Position of the European Parliament adopted at first reading on 18 May 2010 with a view to the adoption of Regulation (EU) No …/2010 of the European Parliament and of the Council on textile names and related labelling of textile products and repealing Council Directive 73/44/EEC, Directive 96/73/EC and Directive 2008/121/EC

(Text with EEA relevance)

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty on the Functioning of the European Union, and in particular Article 114 thereof,

Having regard to the proposal from the European Commission,

Having regard to the opinion of the European Economic and Social Committee (1),

Acting in accordance with the ordinary legislative procedure (2),

Whereas:

(1)

Council Directive 73/44/EEC of 26 February 1973 on the approximation of the laws of the Member States relating to the quantitative analysis of ternary fibre mixtures (3), Directive 96/73/EC of the European Parliament and of the Council of 16 December 1996 on certain methods for the quantitative analysis of binary textile fibre mixtures (4) and Directive 2008/121/EC of the European Parliament and of the Council of 14 January 2009 on textile names (recast) (5), have been amended several times. Since further amendments are to be made, those acts should be replaced by a single legal instrument, in the interest of clarity.

(2)

The Union legislation on textile names and related labelling of textile products is very technical in its content, with detailed provisions that need to be adapted regularly. In order to avoid the need for Member States to transpose the technical amendments into national legislation and thus reduce the administrative burden for national authorities and in order to allow for a faster adoption of new textile fibre names to be applied at the same time throughout the Union , a Regulation appears to be the most appropriate legal instrument to carry out the legislative simplification.

(3)

In order to eliminate potential obstacles to the proper functioning of the internal market caused by diverging provisions of the Member States with regard to the names, composition and labelling of textile products, it is necessary to harmonise the names of textile fibres and the indications appearing on labels, markings and documents which accompany textile products at the various stages of their production, processing and distribution.

(4)	It is appropriate to lay down rules enabling the manufacturers to ask for the inclusion of a new textile fibre name on the list of permitted fibre names.

(5)	Provision should also be made in respect of certain products which are not made exclusively of textile materials but have a textile content which constitutes an essential part of the product or to which attention is specifically drawn by the economic operators .

(6)	The tolerance in respect of ‘ extraneous fibres’, which are not to be stated on the labels, should apply both to pure products and to mixtures.

(7)

Composition labelling should be compulsory to ensure correct information is made available to all consumers in the Union at a uniform level. Where it is technically difficult to specify the composition of a product at the time of manufacture, it should be possible to state, on the label, only those fibres which are known at the time of manufacture provided that they account for a certain percentage of the finished product.

(8)

In order to avoid differences in practice among the Member States, it is necessary to lay down the exact methods of labelling for certain textile products consisting of two or more components, and also to specify the components of textile products that need not be taken into account for purposes of labelling and analysis.

(9)	Textile products subject only to the requirements of inclusive labelling, and those sold by the metre or in cut lengths, should be made available on the market in such a way that the consumer can fully acquaint himself with the information affixed to the overall packaging or the roll.

(10)

The use of descriptions or names which enjoy particular prestige among users and consumers should be made subject to certain conditions. Furthermore, in order to provide information to users and consumers, it is appropriate that the textile fibre names are related to the characteristics of the fibre.

(11)

Market surveillance of products under the scope of this Regulation in the Member States is subject to the provisions of Directive 2001/95/EC of the European Parliament and of the Council of 3 December 2001 on general product safety (6) and those of Regulation (EC) No 765/2008 of the European Parliament and of the Council of 9 July 2008 setting out the requirements for accreditation and market surveillance relating to the marketing of products (7).

(12)

It is necessary to lay down methods for the sampling and analysis of textile products in order to exclude any possibility of objections to the methods used. The methods used for official tests carried out in the Member States to determine the fibre composition of textile products composed of binary and ternary mixtures should be uniform, as regards both the pre-treatment of the sample and its quantitative analysis; therefore this Regulation should lay down uniform methods of analysis for most of the textile products composed of binary and ternary mixtures that are on the market. In order, however, to simplify this Regulation and adapt such uniform methods to technical progress, it is appropriate that the methods set out in this Regulation be turned into European standards. To that end, the Commission should organise the transition from the current system, where the methods are described in this Regulation, to a European standard-based system .

(13)

In the case of fibre mixtures for which there is no uniform method of analysis at Union level, the laboratory responsible for the test should be allowed to determine the composition of such mixtures ▐, indicating in the analysis report the result obtained, the method used and its degree of accuracy ▐.

(14)

This Regulation should set out the agreed allowances to be applied to the anhydrous mass of each fibre during the determination by analysis of the fibre content of textile products, and should give two different agreed allowances for calculating the composition of carded or combed fibres containing wool and/or animal hair. Since it cannot always be established whether a product is carded or combed, and consequently inconsistent results can arise from the application of the tolerances during checks on the conformity of textile products carried out in the Union , the laboratories carrying out those checks should be authorised to apply a single agreed allowance in cases of doubt.

(15)	Rules should be laid down in respect of products exempt from the general labelling requirements of this Regulation, in particular disposable products or products for which only inclusive labelling is required.

(16)	It is appropriate to establish a procedure , including specific requirements , to be observed by any manufacturer or any person acting on his behalf that wishes to include a new textile fibre name on the harmonised list of textile fibre names set out in Annex I. ▐

(17)

In order to ensure that the objectives of this Regulation are attained while keeping pace with technical progress, the Commission should be empowered to adopt, in accordance with Article 290 of the Treaty on the Functioning of the European Union, delegated acts designed to supplement or amend non-essential elements of Annexes I, II, IV, V, VI, VII, VIII and IX to this Regulation.

(18)

In its resolution of 25 November 2009 on origin marking (8) , the European Parliament underlined that consumer protection requires transparent and consistent trade rules, including indications of origin. The aim of such indications should be to enable consumers to be fully aware of the exact origin of the products they purchase, so as to protect them against fraudulent, inaccurate or misleading claims of origin. Harmonised rules should be put in place for that purpose in respect of textile products. As regards imported products, those rules should take the form of mandatory labelling requirements. Concerning products not subject to mandatory origin labelling at Union level, provision should be made for rules ensuring that possible claims of origin are not false or misleading.

(19)

Origin labelling requirements provided for in this Regulation with regard to the specific sector of textile products should be without prejudice to ongoing discussions on a generally applicable regime of origin marking for products imported from third countries, to be set up as part of the Union*s common commercial policy.

(20)

Since the objectives of the action to be taken, that is the adoption of uniform rules for the use of textile names and related labelling of textile products, cannot be sufficiently achieved by the Member States and can therefore, by reason of the scale of the action, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union . In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve those objectives.

(21)	Consumers, in order to be able to make informed choices, should know when purchasing a textile product whether such product comprises non-textile parts of animal origin. It is therefore essential to indicate on the label the presence of animal-derived materials.

(22)

This Regulation is limited to rules concerning the harmonisation of textile fibre names and the labelling of the fibre composition of textile products. In order to eliminate possible obstacles to the proper functioning of the internal market, caused by divergent provisions or practices of Member States, and in order to keep pace with the development of electronic commerce and future challenges in the market for textile products, the harmonisation or standardisation of other aspects of textile labelling should be examined. To that end, the Commission should submit a report to the European Parliament and the Council regarding possible new labelling requirements to be introduced at Union level with a view to facilitating the free movement of textile products in the internal market and achieving throughout the Union a high level of consumer protection. The report should examine in particular consumer views with regard to the amount of information that should be supplied on the label of textile products, and investigate which means other than labelling may be used to provide additional information to consumers. The report should be based on an extended consultation of all stakeholders, consumer surveys and a thorough cost/benefit analysis and should be accompanied, where appropriate, by legislative proposals. The report should examine, in particular, the added value to the consumer of possible labelling requirements in relation to care treatment, size, hazardous substances, flammability and environmental performance of the textile products, the use of language-independent symbols for identifying the textile fibres, social and electronic labelling as well as the inclusion of an identification number on the label to obtain additional on-demand information, especially via the Internet, about the characteristics of the products.

(23)	Directives 73/44/EEC, 96/73/EC and 2008/121/EC should be repealed,

HAVE ADOPTED THIS REGULATION:

Chapter 1

General provisions

Chapter 2

Textile fibre names and related labelling requirements

Article 5

Textile fibre names

1. Only the names of textile fibres listed in Annex I shall be used to indicate the fibre composition of textile products .

2. Use of the names listed in Annex I shall be reserved for fibres whose nature corresponds to the description set out in that Annex.

Those names shall not be used for other fibres, whether on their own or as a root or as an adjective.

The term ‘silk’ may not be used to indicate the shape or particular presentation in continuous yarn of textile fibres.

Article 6

Applications for new textile fibre names

Any manufacturer or any person acting on his behalf may apply to the Commission to add a new textile fibre name to the list set out in Annex I.

The application shall include a technical file compiled in accordance with Annex II.

Article 7

Pure products

1. Only textile products exclusively composed of the same fibre may be labelled as ‘100 %’, ‘pure’ or ‘all’.

Those or similar terms shall not be used for other products.

2. A textile product may be considered as exclusively composed of the same fibre if it contains no more than 2 % by weight of extraneous fibres, provided this quantity is justified as being technically unavoidable in good manufacturing practice and is not added as a matter of routine.

Under the same condition, a textile product, which has undergone a carding process, may be considered as exclusively composed of the same fibre if it contains no more than 5 % by weight of extraneous fibres.

Article 8

Wool products

1. A textile product may be labelled with one of the names referred to in Annex III provided that it is composed exclusively of a wool fibre which has not previously been incorporated in a finished product, which has not been subjected to any spinning and/or felting processes other than those required in the manufacture of that product, and which has not been damaged by treatment or use.

2. By way of derogation from paragraph 1, the names listed in Annex III may be used to describe wool contained in a fibre mixture if all the following conditions are complied with:

(a)	all the wool contained in that mixture satisfies the requirements defined in paragraph 1;

(b)	such wool accounts for not less than 25 % of the total weight of the mixture;

(c)	in the case of a scribbled mixture, the wool is mixed with only one other fibre.

The full percentage composition of such mixture shall be given.

3. The extraneous fibres in the products referred to in paragraphs 1 and 2, including wool products which have undergone a carding process, shall not exceed 0,3 % of their total weight and shall be justified as being technically unavoidable in good manufacturing practice .

Article 9

Multi-fibre textile products

1. A textile product shall be labelled with the name and percentage by weight of all constituent fibres in descending order .

2. By way of derogation from paragraph 1, and without prejudice to Article 7(2), fibres ▐ which individually account for up to 3 % of the total weight of the textile product, or fibres which collectively account for up to 10 % of the total weight, may be designated by the term ‘ other fibres ’, followed by their percentage by weight, provided that they cannot easily be stated at the time of the manufacture .

3. Products having a pure cotton warp and a pure flax weft, in which the percentage of flax accounts for at least 40 % of the total weight of the unsized fabric may be given the name ‘cotton linen union’ which must be accompanied by the composition specification ‘pure cotton warp — pure flax weft’.

4. Without prejudice to Article 5(1) , for textile products the composition of which cannot easily be stated at the time of their manufacture, the term ‘mixed fibres’ or the term ‘unspecified textile composition’ may be used on the label.

5. By way of derogation from paragraph 1, a fibre not included in Annex I may be designated by the term ‘other fibres’, followed by its total percentage by weight, provided that an application for the inclusion of such a fibre in Annex I has been submitted in accordance with Article 6.

Article 10

Decorative fibres and fibres with antistatic effect

Visible, isolable fibres which are purely decorative and do not exceed 7 % of the weight of the finished product need not be mentioned in the fibre compositions provided for in Articles 7 and 9.

The same shall apply to metallic fibres and other fibres which are incorporated in order to obtain an antistatic effect and which do not exceed 2 % of the weight of the finished product.

In the case of the products referred to in Article 9(3), such percentages shall be calculated on the weight of the warp and that of the weft separately.

Article 11

Animal-derived materials

1. Where a textile product comprises non-textile parts of animal origin, it shall bear a label stating that such parts are made of animal-derived materials. The labelling shall not be misleading and shall be presented in such a way that the consumer can easily understand to which part of the product the information on the label refers.

2. Member States shall inform the Commission of the analytical methods they use to identify animal-derived materials by … (9) , and subsequently whenever required in the light of new developments.

3. The Commission shall adopt delegated acts, in accordance with Articles 24, 25 and 26, specifying the detailed form of and modalities for the labelling on the textile products referred to in paragraph 1 and establishing the analytical methods to be used to identify animal-derived materials.

Article 12

Labelling

1. Textile products shall be labelled ▐ whenever they are made available on the market.

The labelling shall be easily accessible, visible and securely affixed to the textile product. It shall remain legible throughout the product's normal period of use. The labelling and the way in which it is affixed shall be carried out in such a way as to minimise discomfort caused to the consumer when wearing the product.

However, the labelling may be replaced or supplemented by accompanying commercial documents when the products are supplied to economic operators within the supply chain , or when they are delivered in performance of an order placed by any contracting authority as defined by Directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts (10).

The names and descriptions referred to in Articles 5, 7, 8 and 9 shall be clearly indicated in such accompanying commercial documents.

Abbreviations shall not be used with the exception of a mechanised processing code, or where they are defined in internationally recognised standards, provided that the abbreviations are explained in the same commercial document.

2. When placing a textile product on the market, the manufacturer or, if the manufacturer is not established in the Union, the importer shall ensure the supply of the label and the accuracy of the information contained therein.

When making a textile product available on the market, the distributor shall ensure that it bears the appropriate labelling prescribed by this Regulation.

A distributor shall be considered a manufacturer for the purposes of this Regulation, where it makes a product available on the market under its own name or trademark, attaches the label or modifies the content of the label.

The economic operators referred to in the first and second subparagraphs shall ensure that any information supplied when textile products are made available on the market cannot be confused with the names and descriptions laid down by this Regulation.

Article 13

The use of names and descriptions

▐

1. When making a textile product available on the market, the names and fibre composition referred to in Articles 5, 7, 8 and 9 shall be indicated in catalogues and trade literature, on packaging and labelling in a manner that is easily accessible, visible and legible and in uniform letter/number size, style and font . That information shall be clearly visible to the consumer before the purchase, including in cases where the purchase is made by electronic means.

2. Trade marks or the name of the undertaking may be given immediately before or after names and descriptions referred to in Articles 5, 7, 8 and 9.

However, where a trade mark or a name of an undertaking contains, on its own or as an adjective or as a root, one of the names listed in Annex I or a name liable to be confused therewith, such trade mark or name shall be given immediately before or after names and descriptions referred to in Articles 5, 7, 8 and 9.

Other information shall be always displayed separately.

3. The labelling ▐ shall be available in any of the official languages of the Union which is easily understood by the end consumer in the Member State in which the textile products are made available. Where appropriate, the textile fibre names may be replaced by, or combined with, intelligible language-independent symbols .

In the case of bobbins, reels, skeins, balls or other small quantity of sewing, mending and embroidery yarns, the first subparagraph shall apply to the inclusive labelling referred to in Article 16(3). Where such products are individually sold to the end user, they may be labelled in any ▐ of the official languages of the Union, provided they also have an inclusive labelling . Where appropriate, the textile fibre names may be replaced by, or combined with, intelligible language-independent symbols .

The Commission shall adopt delegated acts, in accordance with Articles 24, 25 and 26, establishing detailed conditions concerning the use of the symbols referred to in this paragraph.

Article 14

Multi-component textile products

1. Any textile product containing two or more components shall bear a label stating the fibre content of each component.

Such labelling shall not be compulsory for components other than main linings and representing less than 30 % of the total weight of the product.

2. Where two or more textile products have the same fibre content and normally form a single unit, they may bear only one label.

Article 15

Special provisions

The fibre composition of products listed in Annex IV shall be indicated according to the labelling rules set out in that Annex.

Article 16

Derogations

1. By way of derogation from Articles 12, 13 and 14, the rules laid down in paragraphs 2, 3 and 4 of this Article shall apply.

In any case, the products referred to in paragraph 3 and 4 of this Article shall be made available on the market in such a way that the end consumer can fully acquaint himself with the composition of those products.

2. The indication of textile fibre names or fibre composition on the labels or marking of textile products listed in Annex V is not required.

However, where a trade mark or name of an undertaking contains, on its own or as an adjective or as a root, one of the names listed in Annex I or a name liable to be confused therewith, Articles 12, 13 and 14 shall apply.

3. Where textile products listed in Annex VI are of the same type and composition, they may be made available on the market together under an inclusive label.

4. The composition of textile products sold by the metre may be shown on the length or roll made available on the market .

Chapter 3

Market surveillance ▐

Article 17

Market surveillance provisions

1. ▐ Market surveillance authorities shall carry out checks on the conformity of the composition of textile products with the supplied information related to the composition of those products in accordance with this Regulation .

2. For the purpose of determining the fibre composition of textile products, the checks referred to in paragraph 1 shall be carried out in accordance with the methods or harmonised standards set out in Annex VIII.

For those purposes, the fibre percentages set out in Articles 7, 8 and 9 shall be determined by applying to the anhydrous mass of each fibre the appropriate agreed allowance laid down in Annex IX, after having removed the items set out in Annex VII.

In determining the fibre composition set out in Articles 7, 8 and 9, the items listed in Annex VII shall not be taken into account.

3. Any laboratory accredited and approved by the Member State authorities for the testing of textile mixtures for which there is no uniform method of analysis at Union level shall determine the fibre composition of such mixtures ▐, indicating in the analysis report the result obtained , the method used and ▐ the degree of accuracy of that method ▐.

Article 18

Tolerances

1. For the purposes of establishing the composition of textile products intended for the end consumer, the tolerances laid down in paragraphs 2, 3 and 4 shall apply.

2. The presence of extraneous fibres in the composition to be provided in accordance with Article 9 does not need to be indicated if the percentage of those fibres does not reach the following:

(a)	2 % of the total weight of the textile product, provided that this quantity is justified as being technically unavoidable in good manufacturing practice and is not added as a matter of routine;

(b)	under the same condition , 5 % of the total weight in the case of textile products which have undergone a carding process.

Point (b) of this paragraph shall be without prejudice to Article 8(3).

3. A manufacturing tolerance of 3 % shall be permitted between the stated fibre percentages to be provided in accordance with Article 9 and the percentages obtained from analysis carried out in accordance with Article 17, in relation to the total weight of fibres shown on the label. Such tolerance shall also apply to the following:

(a)	fibres which are listed with no indication of their percentage in accordance with Article 9(2);

(b)	the percentage of wool referred to in Article 8(2)(b).

For the purposes of the analysis, the tolerances shall be calculated separately. The total weight to be taken into account in calculating the tolerance referred to in this paragraph shall be that of the fibres of the finished product less the weight of any extraneous fibres found when applying the tolerance referred to in paragraph 2.

The addition of the tolerances referred to in paragraphs 2 and 3 shall be permitted only if any extraneous fibres found by analysis, when applying the tolerance referred to in paragraph 2, prove to be of the same chemical type as one or more of the fibres shown on the label.

4. In the case of particular products for which the manufacturing process requires tolerances higher than those laid down in paragraphs 2 and 3, higher tolerances may be authorised by the Commission when the conformity of the product is checked pursuant to Article 17(1) only in exceptional cases and where adequate justification is provided by the manufacturer.

The manufacturer shall submit a request providing sufficient reasons and evidence of the exceptional manufacturing circumstances.

Chapter 4

Indication of origin for textile products

Article 19

Indication of origin for textile products imported from third countries

1. For the purpose of this Article, the terms ‘origin’ or ‘originating’ shall refer to non-preferential origin in accordance with Articles 35 and 36 of Regulation (EC) No 450/2008 of the European Parliament and of the Council of 23 April 2008 laying down the Community Customs Code (Modernised Customs Code) (11).

2. The importation or placing on the market of textile products imported from third countries, except for those originating in Turkey and the Contracting Parties of the EEA Agreement, shall be subject to origin labelling under the conditions laid down in this Article.

3. The country of origin of textile products shall be indicated on the label of those products. In cases where products are packaged, the indication shall be made separately on the package. The indication of the country of origin may not be replaced by a corresponding indication in accompanying commercial documents.

4. The Commission may adopt delegated acts, in accordance with Articles 24, 25 and 26, to determine cases in which the indication of origin on the packaging shall be accepted in lieu of labelling of the products themselves. This may, in particular, be the case where products normally reach the end consumer or user in their usual packaging.

5. The words ‘made-in’ together with the name of the country of origin shall indicate the origin of textile products. The labelling may be made in any of the official languages of the European Union, which is easily understood by the end consumer in the Member State in which the products are to be made available on the market.

6. The origin labelling shall appear in clearly legible and indelible characters, shall be visible during normal handling, markedly distinct from other information, and shall be presented in a way which is neither misleading nor likely to create an erroneous impression with regard to the origin of the product.

7. Textile products shall bear the required labelling at the time of importation. Such labelling may not be removed or tampered with until the products have been sold to the end consumer or user.

Article 20

Indication of origin for other textile products

1. Where the origin of textile products other than those referred to in Article 19 is indicated on the label, such indication shall be subject to the conditions laid down in this Article.

2. The product shall be deemed to originate in the country where it underwent at least two of the following stages of manufacture:

—

spinning;

ANNEX VIII

METHODS FOR THE QUANTITATIVE ANALYSIS OF BINARY AND TERNARY TEXTILE FIBRE MIXTURES

CHAPTER 1

I. Preparation of test samples and test specimens to determine the fibre composition of textile products

1. FIELD OF APPLICATION

This Chapter gives procedures for obtaining laboratory test samples of a suitable size for pre-treatment for quantitative analysis (i.e. of a mass not exceeding 100 g) from laboratory bulk samples, and for selecting test specimens from the laboratory test samples that have been pre-treated to remove non-fibrous matter (1).

2. DEFINITIONS

2.1. Bulk source— The quantity of material which is assessed on the basis of one series of test results. This may comprise, for example, all the material in one delivery of cloth; all the cloth woven from a particular beam; a consignment of yarn, a bale or a group of bales of raw fibre.

2.2. Laboratory bulk sample— The portion of the bulk source taken to be representative of the whole, and which is available to the laboratory. The size and nature of the laboratory bulk sample shall be sufficient to adequately overcome the variability of the bulk source and to facilitate ease of handling in the laboratory (2).

2.3. Laboratory test sample— That portion of the laboratory bulk sample that is subjected to pre-treatment to remove non-fibrous matter, and from which test specimens are taken. The size and nature of the laboratory test sample shall be sufficient to overcome adequately the variability of the laboratory bulk sample (3).

2.4. Test specimen— The portion of material required to give an individual test result, and selected from the laboratory test sample.

3. PRINCIPLE

The laboratory test sample is selected so that it is representative of the laboratory bulk sample.

The test specimens are taken from the laboratory test sample in such a way that each of them is representative of the laboratory test sample.

4. SAMPLING FROM LOOSE FIBRES

4.1.

Unorientated fibres — Obtain the laboratory test sample by selecting tufts at random from the laboratory bulk sample. Mix thoroughly the whole of the laboratory test sample by means of a laboratory carder (4). Subject the web or mixture, including loose fibres and fibres adhering to the equipment used for mixing, to pre-treatment. Then select test specimens, in proportion to the respective masses, from the web or mixture, from the loose fibres and from the fibres adhering to the equipment.

If the card web remains intact after pre-treatment, select the test specimens in the manner described in 4.2. If the card web is disturbed by the pre-treatment, select each test specimen by removing at random at least 16 small tufts of suitable and approximately equal size and then combine them.

4.2.

Orientated fibres (cards, webs, slivers, rovings) — From randomly selected parts of the laboratory bulk sample cut not less than 10 crosssections each of mass approximately 1 g. Subject the laboratory test sample so formed to the pre-treatment. Recombine the cross-sections by laying them side by side and obtain the test specimen by cutting through them so as to take a portion of each of the 10 lengths.

5. SAMPLING YARN

5.1.

Yarn in packages or in banks — Sample all the packages in the bulk laboratory sample.

Withdraw the appropriate continuous equal lengths from each package either by winding skeins of the same number of turns on a wrap-reel (5), or by some other means. Unite the lengths side by side either as a single skein or as a tow to form the laboratory test sample, ensuring that there are equal lengths from each package in the skein or tow.

Subject the laboratory test sample to the pre-treatment.

Take test specimens from the laboratory test sample by cutting a bunch of threads of equal length from the skein or tow, taking care to see that the bunch contains all the threads in the sample.

If the tex of the yarn is t and the number of packages selected from the laboratory bulk sample is n, then to obtain a test sample of 10 g, the length of yarn to be withdrawn from each package is 106/nt cm

If nt is high, i.e. more than 2 000, wind a heavier skein and cut it across in two places to make a tow of suitable mass. The ends of any sample in the form of a tow shall be securely tied before pre-treatment and test specimens taken from a place remote from the tie bands.

5.2.

Yarn on warp — Take the laboratory test sample by cutting a length from the end of the warp, not less than 20 cm long and comprising all the yarns in the warp except the selvedge yarns, which are rejected. Tie the bunch of threads together near one end. If the sample is too large for pre-treatment as a whole divide it into two or more portions, each tied together for pre-treatment, and reunite the portions after each has been pre-treated separately. Take a test specimen by cutting a suitable length from the laboratory test sample from the end remote from the tie band, and comprising all the threads in the warp. For warp of N threads of tex t, the length of a specimen of mass 1 g is 105/Nt cm.

6. SAMPLING FABRIC

6.1. From a laboratory bulk sample consisting of a single cutting representative of the cloth

Cut a diagonal strip from one corner to the other and remove the selvedges. This strip is the laboratory test sample. To obtain a laboratory test sample of x g, the strip area shall be x104/G cm2.

where G is the mass of the cloth in g/m2.

Subject the laboratory test sample to the pre-treatment and then cut the strip transversely into four equal lengths and superimpose them. Take test specimens from any part of the layered material by cutting through all the layers so that each specimen contains an equal length of each layer.

If the fabric has a woven design, make the width of the laboratory test sample, measured parallel to the warp direction, not less than one warp repeat of the design. If, with this condition satisfied, the laboratory test sample is too large to be treated as a whole, cut it into equal parts, pre-treat them separately, and superimpose these parts before selection of the test specimen, taking care that corresponding parts of the design do not coincide.

6.2. From a laboratory bulk sample consisting of several cuttings

Treat each cutting as described in 6.1, and give each result separately.

7. SAMPLING MADE-UP AND FINISHED PRODUCTS

The bulk laboratory sample is normally a complete made-up or finished product or representative fraction of one.

Where appropriate determine the percentage of the various parts of the product not having the same fibre content, in order to check compliance with Article 14.

Select a laboratory test sample representative of the part of the made-up or finished product, whose composition must be shown by the label. If the product has several labels, select laboratory test samples representative of each part corresponding to a given label.

If the product whose composition is to be determined is not uniform, it may be necessary to select laboratory test samples from each of the parts of the product and to determine the relative proportions of the various parts in relation to the whole product in question.

Then calculate the percentages taking into account the relative proportions of the sampled parts.

Subject the laboratory test samples to the pre-treatment.

Then select test specimens representative of the pre-treated laboratory test samples.

II. Introduction to the methods for the quantitative analysis of textile fibre mixtures

Methods for the quantitative analysis of fibre mixtures are based on two main processes, the manual separation and the chemical separation of fibres.

The method of manual separation shall be used whenever possible since it generally gives more accurate results than the chemical method. It can be used for all textiles whose component fibres do not form an intimate mixture, as for example in the case of yarns composed of several elements each of which is made up of only one type of fibre, or fabrics in which the fibre of the warp is of a different kind to that of the weft, or knitted fabrics capable of being unravelled made up of yarns of different types.

In general, the methods of chemical quantitative analysis are based on the selective solution of the individual components. After the removal of a component the insoluble residue is weighed, and the proportion of the soluble component is calculated from the loss in mass. This first part of the Annex gives the information common to the analyses by this method of all fibre mixtures dealt with in the Annex, whatever their composition. It shall thus be used in conjunction with the succeeding individual sections of the Annex, which contain the detailed procedures applicable to particular fibre mixtures. Occasionally, an analysis is based on a principle other than selective solution; in such cases full details are given in the appropriate section.

Mixtures of fibres during processing and, to a lesser extent, finished textiles may contain non-fibrous matter, such as fats, waxes or dressings, or water-soluble matter, either occurring naturally or added to facilitate processing. Non-fibrous matter must be removed before analysis. For this reason a method for removing oils, fats, waxes and water-soluble matter is also given.

In addition, textiles may contain resins or other matter added to confer special properties. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble component and/or it may be partially or completely removed by the reagent. This type of added matter may thus cause errors and shall be removed before the sample is analysed. If it is impossible to remove such added matter the methods for quantitative chemical analysis given in this Annex are no longer applicable.

Dye in dyed fabrics is considered to be an integral part of the fibre and is not removed.

Analyses are conducted on the basis of dry mass and a procedure is given for determining dry mass.

The result is obtained by applying to the dry mass of each fibre the agreed allowances listed in Annex IX to this Regulation.

Before proceeding with any analysis, all the fibres present in the mixture shall have been identified. In some methods, the insoluble component of a mixture may be partially dissolved in the reagent used to dissolve the soluble component(s).

Where possible, reagents have been chosen that have little or no effect on the insoluble fibres. If loss in mass is known to occur during the analysis, the result shall be corrected; correction factors for this purpose are given. These factors have been determined in several laboratories by treating, with the appropriate reagent as specified in the method of analysis, fibres cleaned by the pre-treatment.

These correction factors apply only to undegraded fibres and different correction factors may be necessary if the fibres have been degraded before or during processing. The procedures given apply to single determinations.

At least two determinations on separate test specimens shall be made, both in the case of manual separation and in the case of chemical separation.

For confirmation, unless technically impossible, it is recommended to use alternative procedures whereby the constituent that was the residue in the standard method is dissolved out first.

CHAPTER 2

Methods for quantitative analysis of certain binary fibre mixtures

I. General information common to the methods given for the quantitative chemical analysis of textile fibre mixtures

I.1. Scope and field of application

The field of application for each method specifies to which fibres the method is applicable.

I.2. Principle

After the identification of the components of a mixture, the non-fibrous material is removed by suitable pre-treatment and then one of the components, usually by selective solution (6). The insoluble residue is weighed and the proportion of soluble component calculated from the loss in mass. Except where this presents technical difficulties, it is preferable to dissolve the fibre present in the greater proportion, thus obtaining the fibre present in the smaller proportion as residue.

I.3. Materials and equipment

I.3.1. Apparatus

I.3.1.1.

Filter crucibles and weighing bottles large enough to contain such crucibles, or any other apparatus giving identical results.

I.3.1.2.

Vacuum flask.

I.3.1.3.

Desiccator containing self-indicating silica gel.

I.3.1.4.

Ventilated oven for drying specimens at 105 ± 3 °C.

I.3.1.5.

Analytical balance, accurate to 0,0002 g.

I.3.1.6.

Soxhlet extractor or other apparatus giving identical results.

I.3.2. Reagents

I.3.2.1.

Light petroleum, redistilled, boiling range 40 to 60 °C.

I.3.2.2.

Other reagents are specified in the appropriate sections of each method. All reagents used should be chemically pure.

I.3.2.3.

Distilled or deionized water.

I.3.2.4.

Acetone.

I.3.2.5.

Orthophosphoric acid.

I.3.2.6.

Urea.

I.3.2.7.

Sodium bicarbonate.

All reagents used shall be chemically pure.

I.4. Conditioning and testing atmosphere

Because dry masses are determined, it is unnecessary to condition the specimen or to conduct analyses in a conditioned atmosphere.

I.5. Laboratory test sample

Take a laboratory test sample that is representative of the laboratory bulk sample and sufficient to provide all the specimens, each of at least 1 g, that are required.

I.6. Pre-treatment of laboratory test sample (7)

Where a substance not to be taken into account in the percentage calculations (see Article 17 of this Regulation) is present, it shall first be removed by a suitable method that does not affect any of the fibre constituents.

For this purpose, non-fibrous matter which can be extracted with light petroleum and water is removed by treating the air-dry test sample in a Soxhlet extractor with light petroleum for one hour at a minimum rate of six cycles per hour. Allow the light petroleum to evaporate from the sample, which is then extracted by direct treatment consisting in soaking the specimen in water at room temperature for one hour and then soaking it in water at 65 ± 5 °C for a further hour, agitating the liquor from time to time. Use a liquor-specimen ratio of 100:1. Remove the excess water from the sample by squeezing, suction or centrifuging and then allow the sample to become air-dry.

In the case of elastolefin or fibre mixtures containing elastolefin and other fibres (wool, animal hair, silk, cotton, flax, true hemp, jute, abaca, alfa, coir, broom, ramie, sisal, cupro, modal, protein, viscose, acrylic, polyamide or nylon, polyester, elastomultiester) the procedure just described shall be slightly modified, in fact light petroleum ether shall be replaced by acetone.

In the case of binary mixtures containing elastolefin and acetate the following procedure shall apply as pre-treatment. Extract the specimen for 10 minutes at 80 °C with a solution containing 25 g/l of 50 % orthophosphoric acid and 50 g/l of urea. Use a liquor-specimen ratio of 100:1. Wash the specimen in water, then drain and wash it in a 0,1 % sodium bicarbonate solution, finally wash it carefully in water.

Where non-fibrous matter cannot be extracted with light petroleum and water, it shall be removed by substituting for the water method described above a suitable method that does not substantially alter any of the fibre constituents. However, for some unbleached, natural vegetable fibres (e.g. jute, coir) it is to be noted that normal pre-treatment with light petroleum and water does not remove all the natural non-fibrous substances; nevertheless additional pre-treatment is not applied unless the sample does contain finishes insoluble in both light petroleum and water.

Analysis reports shall include full details of the methods of pre-treatment used.

I.7. Test procedure

I.7.1. General instructions

I.7.1.1. Drying

Conduct all drying operations for not less than four hours and not more than 16 hours at 105 ± 3 °C in a ventilated oven with the oven door closed throughout. If the drying period is less than 14 hours, the specimen must be weighed to check that its mass has become constant. The mass may be considered to have become constant if, after a further drying period of 60 minutes, its variation is less than 0,05 %.

Avoid handling crucibles and weighing bottles, specimens or residues with bare hands during the drying, cooling and weighing operations.

Dry specimens in a weighing bottle with its cover beside it. After drying, stopper the weighing bottle before removing it from the oven, and transfer it quickly to the desiccator.

Dry the filter crucible in a weighing bottle with its cover beside it in the oven. After drying, close the weighing bottle and transfer it quickly to the desiccator.

Where apparatus other than a filter crucible is used, drying operations in the oven shall be conducted in such a way as to enable the dry mass of the fibres to be determined without loss.

I.7.1.2. Cooling

Conduct all cooling operations in the desiccator the latter placed beside the balance, until complete cooling of the weighing bottles is attained, and in any case for not less than two hours.

I.7.1.3. Weighing

After cooling, complete the weighing of the weighing bottle within two minutes of its removal from the desiccator. Weigh to an accuracy of 0,0002 g.

I.7.2. Procedure

Take from the pre-treated laboratory test sample a test specimen weighing at least 1 g. Cut yarn or cloth into lengths of about 10 mm, dissected as much as possible. Dry the specimen in a weighing bottle, cool it in the desiccator and weigh it. Transfer the specimen to the glass vessel specified in the appropriate section of the relevant Union method, reweigh the weighing bottle immediately and obtain the dry mass of the specimen by difference. Complete the test as specified in the appropriate section of the applicable method. Examine the residue microscopically to check that the treatment has in fact completely removed the soluble fibre.

I.8. Calculation and expression of results

Express the mass of the insoluble component as a percentage of the total mass of fibre in the mixture. The percentage of soluble component is obtained by difference. Calculate the results on the basis of clean, dry mass, adjusted by (a) the agreed allowances and (b) the correction factors necessary to take account of loss of matter during pre-treatment and analysis. Calculations shall be made by applying the formula given in I.8.2.

I.8.1.

Calculation of percentage of insoluble component on clean, dry mass basis, disregarding loss of fibre mass during pre-treatment.

Formula

where

P1%	is the percentage of clean, dry insoluble component,
m	is the percentage of dry mass of the test specimen after pre-treatment,
r	is the dry mass of the residue,
d	is the correction factor for loss in mass of the insoluble component in the reagent during the analysis. Suitable values for ‘d’ are given in the relevant section of each method.

Of course, these values for ‘d’ are the normal values applicable to chemically undegraded fibres.

I.8.2.

Calculation of percentage of insoluble component on clean, dry mass basis, with adjustment by conventional factors and, where appropriate, correction factors for loss of mass during pre-treatment

Formula

where

P1A%	is the percentage of insoluble component adjusted by conventional agreed allowances and for loss in mass during pre-treatment,
P1	is the percentage of clean dry insoluble component as calculated from the formula shown in I.8.1,
a1	is the conventional agreed allowance for the insoluble component (see Annex IX),
a2	is the conventional agreed allowance for the soluble component (see Annex IX),
b1	is the percentage loss of insoluble component caused by pre-treatment,
b2	is the percentage loss of soluble component caused by pre-treatment.

The percentage of the second component is P2A% = 100 – P1A%.

Where a special pre-treatment has been used, the values of b1 and b2 shall be determined, if possible, by submitting each of the pure fibre constituents to the pre-treatment applied in the analysis. Pure fibres are those free from all non-fibrous material except that which they normally contain (either naturally or because of the manufacturing process), in the state (unbleached, bleached) in which they are found in the material to be analysed.

Where no clean separate constituent fibres used in the manufacture of the material to be analysed are available, average values of b1 and b2 as obtained from tests performed on clean fibres similar to those in the mixture under examination, shall be used.

If normal pre-treatment by extraction with light petroleum and water is applied, correction factors b1 and b2 may generally be ignored, except in the case of unbleached cotton, unbleached flax and unbleached hemp, where the loss due to the pre-treatment is conventionally taken as 4 %, and in the case of polypropylene, where it is taken as 1 %.

In the case of other fibres, losses due to the pre-treatment are conventionally disregarded in calculations.

II. Method of quantitative analysis by manual separation

II.1. Field of application

This method is applicable to textile fibres of all types provided they do not form an intimate mixture and that it is possible to separate them by hand.

II.2. Principle

After identification of the constituents of the textile, the non-fibrous material is removed by suitable pre-treatment and then the fibres are separated by hand, dried and weighed in order to calculate the proportion of each fibre in the mixture.

II.3.2.

Desiccator containing self-indicating silica gel.

II.3.3.

Ventilated oven for drying specimens at 105 ± 3 °C.

II.3.4.

Analytical balance, accurate to 0,0002 g.

II.3.5.

Soxhlet extractor, or other apparatus giving an identical result.

II.3.6.

Needle.

II.3.7.

Twist tester or similar apparatus.

II.4. Reagents

II.6. Laboratory test sample

See I.5.

II.7. Pre-treatment of laboratory test sample

See I.6.

II.8. Procedure

II.8.1. Analysis of yarn

Select from the pre-treatment laboratory test sample a specimen of mass not less than 1 g. For a very fine yarn, the analysis may be made on a minimum length of 30 m, whatever its mass.

Cut the yarn into pieces of a suitable length and separate the fibre types by means of a needle and, if necessary, a twist tester. The fibre types so obtained are placed in pre-weighed weighing bottles and dried at 105 ± 3 °C until a constant mass is obtained, as described in I.7.1 and I.7.2.

II.8.2. Analysis of cloth

Select from the pre-treated laboratory test sample, well away from all selvedges, a specimen of mass not less than 1 g, with edges carefully trimmed to avoid fraying and running parallel with weft or warp yarns, or in the case of knitted fabrics in the line of wales and courses. Separate the different fibre types, collect them in pre-weighed weighing bottles and proceed as described in II.8.1.

II.9. Calculation and expression of results

Express the mass of each fibre constituent as a percentage of the total mass of the fibres in the mixture. Calculate the results on the basis of clean, dry mass, adjusted by (a) the agreed allowances and (b) the correction factors necessary to take account of loss of matter during pre-treatment.

II.9.1.

Calculation of percentage masses of clean, dry fibre, disregarding loss of fibre mass during pre-treatment:

Formula

P1%	is the percentage of the first clean, dry component,
m1	is the clean, dry mass of the first component,
m2	is the clean, dry mass of the second component.

II.9.2.

For calculation of the percentage of each component with adjustment by agreed allowances and, where appropriate, by correction factors for loss of matter during pre-treatment, see I.8.2.

III.1. Precision of the methods

The precision indicated in individual methods relates to the reproducibility.

The reproducibility refers to the reliability, i.e. the closeness of agreement between experimental values obtained by operators in different laboratories or at different times using the same method and obtaining individual results on specimens of an identical consistent mixture.

The reproducibility is expressed by confidence limits of the results for a confidence level of 95 %.

Therefore, the difference between two results in a series of analyses made in different laboratories would, given a normal and correct application of the method to an identical and consistent mixture, be exceeded only in five cases out of a 100.

III.2.2.

Give details of any special pre-treatment (see I.6).

III.2.3.

Give the individual results and the arithmetic mean, each to an accuracy of 0,1.

METHOD No 1

ACETATE AND CERTAIN OTHER FIBRES

(Acetone method)

1. FIELD OF APPLICATION

This method is applicable, after removal of non-fibrous matter, to binary mixtures of:

1.	acetate (19) with

wool (1), animal hair (2 and 3), silk (4), cotton (5), flax (7) true hemp (8), jute (9), abaca (10), alfa (11), coir (12), broom (13), ramie (14), sisal (15), cupro (21), modal (22), protein (23), viscose (25), acrylic (26), polyamide or nylon (30), polyester (35) elastomultiester (46), elastolefin (47) and melamine (48).

In no circumstances is the method applicable to acetate fibres which have been deacetylated on the surface.

2. PRINCIPLE

The acetate is dissolved out from a known dry mass of the mixture, with acetone. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of dry acetate is found by difference.

3. APPARATUS AND REAGENTS (additional to those specified in the general instructions)

3.1. Apparatus

Glass-stoppered conical flasks of at least 200 ml capacity.

3.2. Reagent

Acetone.

4. TEST PROCEDURE

Follow the procedure described in the general instructions and proceed as follows:

To the specimen contained in a glass-stoppered conical flask of at least 200 ml capacity, add 100 ml of acetone per gram of specimen, shake the flask, stand it for 30 minutes at room temperature, stirring from time to time, and then decant the liquid through the weighed filter crucible.

Repeat the treatment twice more (making three extractions in all), but for periods of 15 minutes only, so that the total time of treatment in acetone is one hour. Transfer the residue to the filter crucible. Wash the residue in the filter crucible with acetone and drain with suction. Refill the crucible with acetone and allow to drain under gravity.

Finally, drain the crucible with suction, dry the crucible and residue, and cool and weigh them.

5. CALCULATION AND EXPRESSION OF RESULTS

Calculate the results as described in the general instructions. The value of ‘d’ is 1,00, except for melamine, for which ‘d’ = 1,01.

6. PRECISION

On a homogeneous mixture of textile materials, the confidence limits of results obtained by this method are not greater than ± 1 for a confidence level of 95 %.

METHOD No 2

CERTAIN PROTEIN FIBRES AND CERTAIN OTHER FIBRES

(Method using hypochlorite)

1. FIELD OF APPLICATION

This method is applicable, after removal of non-fibrous matter, to binary mixtures of:

1.	certain protein fibres, namely: wool (1), animal hair (2 and 3), silk (4), protein (23) with

2.	cotton (5), cupro (21), viscose (25), acrylic (26), chlorofibres (27), polyamide or nylon (30), polyester (35), polypropylene (37), elastane (43), glass fibre (44) elastomultiester (46), elastolefin (47) and melamine (48).

If different protein fibres are present, the method gives the total of their amounts but not their individual quantities.

2. PRINCIPLE

The protein fibre is dissolved out from a known dry mass of the mixture, with a hypochlorite solution. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of dry protein fibre is found by difference.

Either lithium hypochlorite or sodium hypochlorite can be used for the preparation of the hypochlorite solution.

Lithium hypochlorite is recommended in cases involving a small number of analyses or for analyses conducted at fairly lengthy intervals. This is because the percentage of hypochlorite in solid lithium hypochlorite — unlike that in sodium hypochlorite — is virtually constant. If the percentage of hypochlorite is known, hypochlorite content need not be checked iodometrically for each analysis, since a constant weighed portion of lithium hypochlorite can be employed.

3. APPARATUS AND REAGENTS (other than those specified in the general instructions)

3.1. Apparatus

(i)	Erlenmeyer flask with ground-glass stopper, 250 ml.

(ii)	Thermostat, adjustable to 20 (± 2) °C.

3.2. Reagents

(i) Hypochlorite reagent

(a) Lithiumhypochloritesolution

This consists of a freshly prepared solution containing 35 (± 2) g/l of active chlorine (approximately 1 M), to which 5 (± 0,5) g/l of previously dissolved sodium hydroxide is added. To prepare, dissolve 100 grams of lithium hypochlorite containing 35 % active chlorine (or 115 grams containing 30 % active chlorine) in approximately 700 ml of distilled water, add 5 grams of sodium hydroxide dissolved in approximately 200 ml of distilled water and make up to 1 litre with distilled water. The solution which has been freshly prepared need not be checked iodometrically.

(b) Sodiumhypochloritesolution

This consists of a freshly prepared solution containing 35 (± 2) g/l of active chlorine (approximately 1 M) to which 5 (± 0,5) g/l of previously dissolved sodium hydroxide is added.

Check the active chlorine content of the solution iodometrically before each analysis.

(ii) Acetic acid, dilute solution

Dilute 5 ml of glacial acetic acid to 1 litre with water.

4. TEST PROCEDURE

Follow the procedure described in the general instructions and proceed as follows: mix approximately 1 gram of the sample with approximately 100 ml of the hypochlorite solution (lithium or sodium hypochlorite) in the 250 ml flask and agitate thoroughly in order to wet out the sample.

Then heat the flask for 40 minutes in a thermostat at 20 °C and agitate continuously, or at least at regular intervals. Since the dissolution of the wool proceeds exothermically, the reaction heat of this method must be distributed and removed. Otherwise, considerable errors may be caused by the incipient dissolution of the non-soluble fibres.

After 40 minutes, filter the flask contents through a weighed glass-filter crucible and transfer any residual fibres into the filter crucible by rinsing the flask with a little hypochlorite reagent. Drain the crucible with suction and wash the residue successively with water, dilute acetic acid, and finally water, draining the crucible with suction after each addition. Do not apply suction until each washing liquor has drained under gravity.

Finally, drain the crucible with suction, dry the crucible with the residue, and cool and weigh them.

5. CALCULATION AND EXPRESSION OF RESULTS

Calculate the results as described in the general instructions. The value of ‘d’ is 1,00, except for cotton, viscose, modal and melamine for which ‘d’ = 1,01, and unbleached cotton, for which ‘d’ = 1,03.

6. PRECISION

On homogeneous mixtures of textile materials, the confidence limits for results obtained by this method are not greater than ± 1 for a confidence level of 95 %.

METHOD No 3

VISCOSE, CUPRO OR CERTAIN TYPES OF MODAL AND COTTON

(Method using formic acid and zinc chloride)

1. FIELD OF APPLICATION

This method is applicable, after removal of non-fibrous matter, to binary mixtures of:

1.	viscose (25) or cupro (21), including certain types of modal fibre (22), with

2.	cotton (5), elastolefin (47) and melamine (48).

If a modal fibre is found to be present, a preliminary test shall be carried out to see whether it is soluble in the reagent.

This method is not applicable to mixtures in which the cotton has suffered extensive chemical degradation nor when the viscose or cupro is rendered incompletely soluble by the presence of certain dyes or finishes that cannot be removed completely.

2. PRINCIPLE

The viscose, cupro or modal fibre is dissolved from a known dry mass of the mixture, with a reagent consisting of formic acid and zinc chloride. The residue is collected, washed, dried and weighed; its corrected mass is expressed as a percentage of the dry mass of the mixture. The percentage of dry viscose, cupro or modal fibre is found by difference.

3. APPARATUS AND REAGENTS (other than those specified in the general instructions)

3.1. Apparatus

(i)	Glass-stoppered conical flasks of at least 200 ml capacity.

(ii)	Apparatus for maintaining flasks at 40 (± 2) °C.

3.2. Reagents

(i)

Solution containing 20 g of fused anhydrous zinc chloride and 68 g of anhydrous formic acid made up to 100 g with water (namely 20 parts by mass of fused anhydrous zinc chloride to 80 parts by mass of 85 % m/m formic acid).

NB:

Attention is drawn, in this respect, to point I.3.2.2, which lays down that all reagents used shall be chemically pure; in addition, it is essential to use only fused anhydrous zinc chloride.

(ii)	Ammonium hydroxide solution: dilute 20 ml of a concentrated ammonia solution (specific gravity 0,880 g/ml) to 1 litre with water.

4. TEST PROCEDURE

Follow the procedure described in the general instructions and proceed as follows: place the specimen immediately in the flask, pre-heated to 40 °C. Add 100 ml of the solution of formic acid and zinc chloride, pre-heated to 40 °C per gram of specimen. Insert the stopper and shake the flask vigorously. Keep the flask and its contents at a constant temperature of 40 °C for two hours and a half, shaking the flask at hourly intervals.

Filter the contents of the flask through the weighed filter crucible and with the help of the reagent transfer to the crucible any fibres remaining in the flask. Rinse with 20 ml of reagent.

Wash crucible and residue thoroughly with water at 40 °C. Rinse the fibrous residue in approximately 100 ml of cold ammonia solution (3.2.ii) ensuring that this residue remains wholly immersed in the solution for 10 minutes; then rinse thoroughly with cold water.

Do not apply suction until each washing liquor has drained under gravity.

Finally, drain the remaining liquid with suction, dry the crucible and residue, and cool and weigh them.

5. CALCULATION AND EXPRESSION OF RESULTS

Calculate the results as described in the general instructions. The value of ‘d’ is 1,02 for cotton, 1,01 for melamine and 1,00 for elastolefin.

6. PRECISION

On a homogeneous mixture of textile materials, the confidence limits of results obtained by this method are not greater than ± 2 for a confidence level of 95 %.

METHOD No 4

POLYAMIDE OR NYLON, AND CERTAIN OTHER FIBRES

(Method using 80 % m/m formic acid)

1. FIELD OF APPLICATION

5. TEST PROCEDURE

5.1. General instructions

Follow the procedure described in the general instructions as regards the selection, drying and weighing of the specimen.

Transfer the specimen to a Kjeldahl digestion flask. To the specimen weighing at least 1 g contained in the digestion flask, add, in the following order, 2,5 g potassium sulphate, 0,1 — 0,2 g selenium dioxide and 10 ml sulphuric acid (relative density 1,84). Heat the flask, gently at first, until the whole of the fibre is destroyed, and then heat it more vigorously until the solution becomes clear and almost colourless. Heat it for a further 15 minutes. Allow the flask to cool, dilute the contents carefully with 10 — 20 ml water, cool, transfer the contents quantitatively to a 200 ml graduated flask and make up to volume with water to form the digest solution. Place about 20 ml of boric acid solution in a 100 ml conical flask and place the flask under the condenser of the Kjeldahl distillation apparatus so that the delivery tube dips just below the surface of the boric acid solution. Transfer exactly 10 ml of digest solution to the distillation flask, add not less than 5 ml of sodium hydroxide solution to the funnel, lift the stopper slightly and allow the sodium hydroxide solution to run slowly into the flask. If the digest solution and sodium hydroxide solution remain as two separate layers, mix them by gentle agitation. Heat the distillation flask gently and pass it into steam from the generator. Collect about 20 ml of distillate, lower the conical flask so that the tip of the delivery tube of the condenser is about 20 mm above the surface of the liquid and distil for 1 minute more. Rinse the tip of the delivery tube with water, catching the washings in the conical flask. Remove the conical flask and replace it with another conical flask containing roughly 10 ml of boric acid solution and collect about 10 ml distillate.

Titrate the two distillates separately with 0,02N sulphuric acid, use the mixed indicator. Record the total titre for the two distillates. If the titre for the second distillate is more than 0,2 ml, repeat the test and start the distillation again using a fresh aliquot of digest solution.

Carry out a blank determination, i.e. digestion and distillation using the reagents only.

1.	chlorofibres (27) based on homopolymers of vinyl chloride, whether after-chlorinated or not, elastolefin (47) with

2.	cotton (5), acetate (19), cupro (21), modal (22), triacetate (24), viscose (25), certain acrylics (26), certain modacrylics (29), polyamide or nylon (30), polyester (35), elastomultiester (46) and melamine (48).

The modacrylics concerned are those which give a limpid solution when immersed in concentrated sulphuric acid (relative density 1,84 at 20 °C).

This method can be used in place of method Nos 8 and 9.

2. PRINCIPLE

The constituent other than the chlorofibre or the elastolefin (i.e. the fibres mentioned in paragraph 1.2) is dissolved out from a known dry mass of the mixture with concentrated sulphuric acid (relative density 1,84 at 20 °C).

The residue, consisting of the chlorofibre or the elastolefin, is collected, washed, dried and weighed; its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of the second constituents is obtained by difference.

3. APPARATUS AND REAGENTS (other than those specified in the general instructions)

3.1. Apparatus

4. TEST PROCEDURE

Follow the procedure described in the general instructions, then proceed as follows:

To the specimen contained in the flask (3.1 (i)) add 100 ml of sulphuric acid (3.2 (i)) per gram of specimen.

Allow the contents of the flask to remain at room temperature for 10 minutes and during that time stir the test specimen occasionally by means of the glass rod. If a woven or knitted fabric is being treated, wedge it between the wall of the flask and the glass rod and exert a light pressure in order to separate the material dissolved by the sulphuric acid.

Decant the liquid through the weighed filter crucible. Add to the flask a fresh portion of 100 ml of sulphuric acid (3.2 (i)) and repeat the same operation.Transfer the contents of the flask to the filter crucible and transfer the fibrous residue there with the aid of the glass rod. If necessary, add a little concentrated sulphuric acid (3.2 (i)) to the flask in order to remove any fibres adhering to the wall. Drain the filter crucible with suction; remove the filtrate by emptying or changing the filter-flask, wash the residue in the crucible successively with 50 % sulphuric acid solution (3.2 (ii)), distilled or de-ionizedwater (I.3.2.3 of the general instructions, ammonia solution (3.2 (iii)) and finally wash thoroughly with distilled or de-ionized water, draining the crucible with suction after each addition.

CHAPTER 3

Quantitative analysis of ternary fibre mixtures

INTRODUCTION

In general, the methods of quantitative chemical analysis are based on the selective solution of the individual components. There are four possible variants of this method:

Using two different test specimens, a component (a) is dissolved from the first test specimen, and another component (b) from the second test specimen. The insoluble residues of each specimen are weighed and the percentage of each of the two soluble components is calculated from the respective losses in mass. The percentage of the third component (c) is calculated by difference.

Using two different test specimens, a component (a) is dissolved from the first test specimen and two components (a and b) from the second test specimen. The insoluble residue of the first test specimen is weighed and the percentage of the component (a) is calculated from the loss in mass. The insoluble residue of the second test specimen is weighed; it corresponds to component (c). The percentage of the third component (b) is calculated by difference.

Using two different test specimens, two components (a and b) are dissolved from the first test specimen and two components (b and c) from the second test specimen. The insoluble residues correspond to the two components (c) and (a) respectively. The percentage of the third component (b) is calculated by difference.

Using only one test specimen, after removal of one of the components, the insoluble residue formed by the two other fibres is weighed and the percentage of the soluble component is calculated from the loss in mass. One of the two fibres of the residue is dissolved, the insoluble component is weighed and the percentage of the second soluble component is calculated from the loss in mass.

Where a choice is possible, it is advisable to use one of the first three variants.

Where chemical analysis is used, the expert responsible for the analysis must take care to select methods employing solvents which dissolve only the correct fibre(s), leaving the other fibre(s) intact.

By way of example, a table is given in Chapter 3.VI which contains a certain number of ternary mixtures, together with methods for analysing binary mixtures which can, in principle, be used for analysing these ternary mixtures.

In order to reduce the possibility of error to a minimum, it is recommended that, whenever possible, chemical analysis using at least two of the four abovementioned variants shall be made.

Before proceeding with any analysis, all the fibres present in the mixture must be identified. In some chemical methods, the insoluble component of a mixture may be partially dissolved in the reagent used to dissolve the soluble component(s). Wherever possible, reagents have been chosen that have little or no effect on the insoluble fibres. If a loss in mass is known to occur during the analysis, the result shall be corrected; correction factors are given for this purpose. These factors have been determined in several laboratories by treating, with the appropriate reagent as specified in the method of analysis, fibres cleaned by the pre-treatment. These correction factors apply only to undergraded fibres and different correction factors may be necessary if the fibres have been degraded before or during processing. If the fourth variant, in which a textile fibre is subjected to the successive action of two different solvents, must be used, correction factors must be applied for possible losses in mass undergone by the fibre in the two treatments. At least two determinations shall be made, both in the case of manual separation and in the case of chemical separation.

I. General information on methods for the quantitative chemical analysis of ternary fibre mixtures

Information common to the methods given for the quantitative chemical analysis of ternary fibre mixtures.

I.1. Scope and field of application

The field of application of each method for analysing binary fibre mixtures specifies to which fibres the method is applicable. (See Chapter 2 relating to certain methods for the quantitative analysis of binary fibre mixtures).

I.2. Principle

After the identification of the components of a mixture, the non-fibrous material is removed by suitable pre-treatment and then one or more of the four variants of the process of selective solution described in the introduction is applied. Except where this presents technical difficulties, it is preferable to dissolve the major fibre component so as to obtain the minor fibre component as final residue.

I.3. Materials and equipment

I.3.1. Apparatus

I.3.1.1.

Filter crucibles and weighing bottles large enough to contain such crucibles, or any other apparatus giving identical results.

I.3.1.2.

Vacuum flask.

I.3.1.3.

Desiccator containing self-indicating silica gel.

I.3.1.4.

Ventilated oven for drying specimens at 105 ± 3 °C.

I.3.1.5.

Analytical balance, accurate to 0,0002 g.

I.3.1.6.

Soxhlet extractor or other apparatus giving identical results.

I.3.2. Reagents

I.3.2.1.

Light petroleum, redistilled, boiling range 40 to 60 °C.

I.3.2.2.

Other reagents are specified in the appropriate sections of each method.

All reagents used shall be chemically pure.

I.3.2.3.

Distilled or deionized water.

I.3.2.4.

Acetone.

I.3.2.5.

Orthophosphoric acid.

I.3.2.6.

Urea.

I.3.2.7.

Sodium bicarbonate.

I.4. Conditioning and testing atmosphere

Because dry masses are determined, it is unnecessary to condition the specimen or to conduct analyses in a conditioned atmosphere.

I.5. Laboratory test sample

Take a laboratory test sample that is representative of the laboratory bulk sample and sufficient to provide all the specimens, each of at least 1 g, that are required.

I.6. Pre-treatment of laboratory test sample (12)

For this purpose, non-fibrous matter which can be extracted with light petroleum and water is removed by treating the air-dry test sample in a Soxhlet extractor with light petroleum for one hour at a minimum rate of six cycles per hour. Allow the light petroleum to evaporate from the sample, which is then extracted by direct treatment consisting in soaking the specimen in water at room temperature for one hour and then soaking it in water at 65 ± 5 °C for a further hour, agitating the liquor from timeto time. Use a liquor:specimen ratio of 100:1. Remove the excess water from the sample by squeezing, suction or centrifuging and then allow the sample to become air-dry.

Where non-fibrous matter cannot be extracted with light petroleum and water, it shall be removed by substituting for the water method described above a suitable method that does not substantially alter any of the fibre constituents. However, for some unbleached, natural vegetable fibres (e.g. jute, coir) it is to be noted that normal pretreatment with light petroleum and water does not remove all the natural non-fibrous substances; nevertheless additional pre-treatment is not applied unless the sample does contain finishes insoluble in both light petroleum and water.

Analysis reports shall include full details of the methods of pre-treatment used.

I.7. Test procedure

I.7.1. General instructions

Conduct all drying operations for not less than 4 hours and not more than 16 hours at 105 ± 3 °C in a ventilated oven with the oven door closed throughout. If the drying period is less than 14 hours, the specimen must be checkweighed to determine whether its mass is constant. The mass may be considered as constant if, after a further drying period of 60 minutes, its variation is less than 0,05 %.

Avoid handling crucibles and weighing bottles, specimens or residues with bare hands during the drying, cooling and weighing operations.

Dry specimens in a weighing bottle with its cover beside it. After drying, stopper the weighing bottle before removing it from the oven, and transfer it quickly to the desiccator.

Dry the filter crucible in a weighing bottle with its cover beside it in the oven. After drying, close the weighing bottle and transfer it quickly to the desiccator.

Where apparatus other than a filter crucible is used, drying operations shall be conducted in the oven so as to determine the dry mass of the fibres without loss.

I.7.1.2. Cooling

If normal pre-treatment by extraction with light petroleum and water is applied, correction factors b1, b2 and b3 may generally be ignored, except in the case of unbleached cotton, unbleached flax and unbleached hemp where the loss due to pre-treatment is usually accepted as 4 % and in the case of polypropylene as 1 %.

In the case of other fibres, losses due to pre-treatment are usually disregarded in calculations.

II. Method of quantitative analysis by manual separation of ternary fibre mixtures

II.8.2. Analysis of cloth

Take from the pre-treated laboratory test sample a specimen of mass not less than 1 g, not including a selvedge with edges carefully trimmed to avoid fraying and running parallel with weft or warp yarns, or in the case of knitted fabrics in the line of the wales and courses. Separate the different types of fibres and collect them in pre-weighed weighing bottles and proceed as described in II.8.1.

P2 % is the percentage of the second clean dry component;

P3 % is the percentage of the third clean dry component;

m1 is the clean dry mass of the first component;

m2 is the clean dry mass of the second component;

m3 is the clean dry mass of the third component.

II.9.2.

For calculation of the percentage of each component with adjustment by conventional agreed allowances and, where appropriate, by correction factors for losses in mass during pre-treatment: see I.8.2.

III. Method of quantitative analysis of ternary fibre mixtures by a combination of manual separation and chemical separation

Wherever possible, manual separation shall be used, taking account of the proportions of components separated before proceeding to any chemical treatment of each of the separate components.

IV.1. Precision of the methods

The precision indicated in each method of analysis of binary mixtures relates to the reproducibility (see Chapter 2 relating to certain methods for the quantitative analysis of binary textile fibre mixtures).

Reproducibility refers to the reliability, ie the closeness of agreement between experimental values obtained by operators in different laboratories or at different times using the same method and obtaining individual results on specimens of an identical homogeneous mixture.

Reproducibility is expressed by confidence limits of the results for a confidence level of 95 %.

By this is meant that the difference between two results in a series of analyses made in different laboratories would, given a normal and correct application of the method to an identical and homogeneous mixture, be exceeded only in 5 cases out of 100.

To determine the precision of the analysis of a ternary mixture the values indicated in the methods for the analysis of binary mixtures which have been used to analyse the ternary mixture are applied in the usual way.

Given that in the four variants of the quantitative chemical analysis of ternary mixtures, provision is made for two dissolutions (using two separate specimens for the first three variants and a single specimen for the fourth variant) and, assuming that E1 and E2 denote the precision of the two methods for analysing binary mixtures, the precision of the results for each component is shown in the following table:

Component fibre	Variants
Component fibre	1	2 and 3	4.
a	E1	E1	E1
b	E2	E1+E2	E1+E2
c	E1+E2	E2	E1+E2

If the fourth variant is used, the degree of precision may be found to be lower than that calculated by the method indicated above, owing to possible action of the first reagent on the residue consisting of components b and c, which would be difficult to evaluate.

IV.2. Test report

IV.1.

Indicate the variant(s) used to carry out the analysis, the methods, reagents and correction factors.

IV.2.

Give details of any special pre-treatments (See I.6).

IV.3.

Give the individual results and the arithmetic mean, each to the 1st decimal place.

IV.4.

Wherever possible, state the precision of the method for each component, calculated according to the table in section IV.1.

V. Examples of the calculation of percentages of the components of certain ternary mixtures using some of the variants described in point I.8.1.

Consider the case of a fibre mixture which gave the following components when qualitatively analysed for raw material composition: 1. carded wool; 2. nylon (polyamide); 3. unbleached cotton.

VARIANT No. 1

Using this variant, that is using two different specimens and removing one component (a = wool) by dissolution from the first specimen and a second component (b = polyamide) from the second specimen, the following results can be obtained:

1.	Dry mass of the first specimen after pre-treatment is(m1) = 1,6000 g

2.	Dry mass of the residue after treatment with alkaline sodium hypochlorite (polyamide+cotton) (r1) = 1,4166 g

3.	Dry mass of the second specimen after pre-treatment (m2) = 1,8000 g

4.	Dry mass of the residue after treatment with formic acid (wool+cotton) (r2) = 0,9000 g

Treatment with alkaline sodium hypochlorite does not entail any loss in mass of polyamide, while unbleached cotton losses 3 %, therefore d1 = 1,0 and d2 = 1,03.

Treatment with formic acid does not entail any loss in mass for wool or unbleached cotton, therefore d3 and d4 = 1,0.

If the values obtained by chemical analysis and the correction factors are substituted in the formula under I.8.1.1, the following result is obtained:

P1 % (wool) = [1,03/1,0 – 1,03 × 1,4166/1,6000 + 0,9000/1,8000 × (1 – 1,03/1,0)] × 100 = 10,30

P2 % (polyamide) = [1,0/1,0 – 1,0 × 0,9000/1,8000 + 1,4166/1,6000 × (1– 1,0/,0)] × 100 = 50,00

P3 % (cotton) = 100 – (10,30 + 50,00) = 39,70

The percentages of the various clean dry fibres in the mixture are as follows:

wool	10,30 %
polyamide	50,00 %
cotton	39,70 %

These percentages must be corrected according to the formulae under I.8.2, in order to take account of the conventional agreed allowances and the correction factors for any losses in mass after pre-treatment.

As indicated in Annex IX, the conventional agreed allowances are as follows: carded wool 17,0 %, polyamide 6,25 %, cotton 8,5 %, also unbleached cotton shows a loss in mass of 4 %, after pre-treatment with light petroleum and water.

Therefore:

P1A % (wool) = 10,30 × [1 + (17,0 + 0,0)/100]/[10,30 × (1 + (17,0 + 0,0)/100) + 50,00 × (1 + (6,25 + 0,0)/100) + 39,70 × (1 + (8,5 + 4,0/100)] × 100 = 10,97

P2A % (polyamide) = 50,0 × (1+ (6,25 + 0,0)/100)/109,8385 × 100 = 48,37

P3A % (cotton) = 100 – (10,97 + 48,37) = 40,66

The raw material composition of the yarn is therefore as follows:

polyamide	48,4 %
cotton	40,6 %
wool	11,0 %
	100,0 %

VARIANT No. 4:

Consider the case of a fibre mixture which when qualitatively analysed gave the following components: carded wool, viscose, unbleached cotton.

Suppose that using variant 4, that is successively removing two components from the mixture of one single specimen, the following results are obtained:

1.	Dry mass of the specimen after pre-treatment (m1) = 1,6000 g

2.	Dry mass of the residue after treatment with alkaline sodium hypochlorite (viscose+cotton) (r1) = 1,4166 g

3.	Dry mass of the residue after the second treatment of the residue r1 with zinc chloride/formic acid (cotton) (r2) = 0,6630 g

Treatment with alkaline sodium hypochlorite does not entail any loss in mass of viscose, while unbleached cotton losses 3 %, therefore d1 = 1,0 and d2 = 1,03.

As a result of treatment with formic acid-zinc chloride, the mass of cotton increases by 4 %, so that d3 = 1,03 × 0,96 = 0,9888, rounded to 0,99, (d3 being the correction factor for the respective loss or increase in mass of the third component in the first and second reagents).

If the values obtained by chemical analysis and the correction factors are substituted in the formulae given in I.8.1.4, the following result is obtained:

P2 % (viscose) = 1,0 × 1,4166/1,6000 × 100 – 1,0/1,03 × 40,98 = 48,75 %

P3 % (cotton) = 0,99 × 0,6630/1,6000 × 100 = 41,02 %

P1 % (wool) = 100 - (48,75 + 41,02) = 10,23 %

As has already been indicated for Variant 1, these percentages must be corrected by the formulae indicated in point I.8.2.

P1A % (wool) = 10,23 × [1 + (17,0 + 0,0/100)]/[10,23 × (1 + (17,00 + 0,0)/100) + 48,75 × (1 + (13 + 0,0/100) + 41,02 × (1 + (8,5 + 4,0)/100)] × 100 = 10,57 %

P2A % (viscose) = 48,75 × [1 + (13 + 0,0)/100]/113,2041 × 100 = 48,65 %

P3A % (cotton) = 100 - (10,57 + 48,65) = 40,78 %

The raw material composition of the mixture is therefore as follows:

viscose	48,6 %
cotton	40,8 %
wool	10,6 %
	100,0 %
