18、6 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a

19、subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission

20、 (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical com

21、mittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not

22、 be held responsible for identifying any or all such patent rights. ISO 1833-2 was prepared by Technical Committee ISO/TC 38, Textiles.

31、he methods of quantitative analysis of mixtures of textile fibres are based on two processes: the manual separation and the chemical separation of fibre types. The method of manual separation should be used whenever possible, since it generally gives more accurate results than the chemical method. I

32、t 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 one type of fibre, or fabrics in which the warp is of a different type of fibre from the weft, or knitted fabrics capa

33、ble of being unravelled and made up of yarns of different types. In general, the methods for quantitative chemical analysis of ternary fibre mixtures are based on the selective solution of the individual components of the mixture. Four variants of this procedure are possible. Variant 1: Using two di

34、fferent test specimens, component (a) is dissolved from the first test specimen and component (b) from the second test specimen. The insoluble residues of each test specimen are weighed and the percentage of each soluble component is calculated from the respective losses in mass. The percentage of t

35、he third component (c) is calculated by difference. Variant 2: 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

36、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. Variant 3: Using two different test specimens, two components (a and b) are dis

37、solved 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. Variant 4: Using only one test specimen, one of the

38、 components is removed, after which 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

39、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, take care to choose methods prescribing solvents which dissolve only the required fibre or fibres, and leave undissolved the oth

40、er fibre or fibres. By way of example, Annex B 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, w

41、henever possible, chemical analysis using at least two of the four above-mentioned variants should be made. Mixtures of fibres used during processing and, to a lesser extent, in finished textiles may contain non-fibrous matter such as fats, waxes or dressings, or water-soluble matter either occurrin

42、g naturally or added to facilitate processing. Non-fibrous matter should be removed before analysis. A method of pre-treatment for removing oils, fats, waxes and water-soluble matter is given in ISO 1833-1:2006, Annex A. In addition, textiles may contain resins or other matter added to confer specia

43、l properties. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble components and/or it may be partially or completely removed by the reagents. ISO 1833-2:2006(E) ISO 2006 All rights reserved viiThis type of added matter may thus cause er

44、rors and should be removed before the sample is analysed. If it is impossible to remove such added matter, the methods for quantitative chemical analysis given in Annex B are no longer applicable. Dye in dyed fibre is considered to be an integral part of the fibre and is not removed. Analyses are co

45、nducted on the basis of dry mass and a procedure is given for its determination. The result is expressed by reference to the dry mass or by reference to this mass after application of the conventional recovery rate. Before proceeding with any analysis, all the fibres present in the mixture should be

46、 identified. In some chemical methods, the insoluble components of a mixture may be partially dissolved in the reagent used to dissolve the soluble component or components. Whenever possible, reagents have been chosen that have little or no effect on the insoluble fibres. If a loss in mass is known

47、to occur during the analysis, the result should 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 correct

48、ion factors apply only to undegraded 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, should be used, correction fact

49、ors should be applied for possible losses in mass undergone by the fibre in the two treatments. At least two determinations should be made, both in the case of manual separation and in the case of chemical separation.
