National foreword This standard has been prepared by Technical Committee ISO/TC 38 “Textiles” in collaboration with Technical Committee CEN/TC 248 “Textile and textile products” (Secretariat: BSI, United Kingdom). The responsible German b
5、ody involved in its preparation was the Normenausschuss Materialprfung (Materials Testing Standards Committee), Working Committee NA 062-05-12 AA Textilchemische Prfver-fahren und Fasertrennung. The Introduction of ISO 1833-1 is summarized below as a help to users of this standard: In general, the m
6、ethods described in the various parts of ISO 1833 are based on the selective solution of an individual component. Once a component is dissolved from a test specimen, the insoluble residue is weighed and the percentage of the soluble component(s) is calculated from loss in mass. ISO 1833-1 gives info
7、rmation that is common to all of these analytical methods for all fibre mixtures, regardless of their composition. This general information should be used when applying the other parts of the ISO 1833 series; each of these parts contains a more detailed description of a method that is applicable for
8、 a specific fibre mixture. If one of these methods is based on a principle other than selective solution, this is expressly stated and described in detail in the respective part of the standards series. Fibre mixtures used during processing and, to a lesser extent, in finished textiles may contain f
9、ats, waxes or dressings which either occur naturally or are added to facilitate processing. Fibre mixtures may also contain salts and other water-soluble matter. Some or all of these substances can separate during analysis and be erroneously calculated as soluble fibre components. To avoid this erro
10、r, 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 bind the fibres or to confer special properties, such as
11、water repellence or crease resistance. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble components and/or may be partially or completely removed by the reagents. This type of added matter can thus also cause errors and should be remov
12、ed before the sample is analysed. If it is impossible to remove such added matter, the methods are no longer applicable. Dye in dyed fibre is considered to be an integral part of the fibre and is not removed. Most textile fibres contain water, the amount of which depends on the type of fibre and the
13、 relative humidity of the ambient air. These analyses are conducted on the basis of dry mass, and a procedure for determining the dry mass of analytical samples and residues is given in ISO 1833-1. The result is thus obtained on the basis of the dry mass of the dry fibres only. Provisions have been
14、made for recalculating results on the basis of a) permissible deviations agreed upon for moisture content1)b) permissible deviations agreed upon for humidity, as well as for 1) the fibrous matter separated during pre-treatment, and 2) non-fibrous matter (e.g. dressings, processing oils or sizing ass
15、istants) which can be considered as being a commonly used commercial article that is part of the fibre. 1) Commonly used conditioning values shall be used for each fibre, where these are available. DIN EN ISO 1833-2:2011-01 3 In some methods, the insoluble components of a mixture may be partially di
16、ssolved in the reagent used to dissolve the soluble component(s). Whenever 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 should be corrected; correction factors are given for this purpose
17、. These factors have been determined in several laboratories by treating, with the appropriate reagent as specified in the method of analysis, fibres cleaned by pre-treatment. These correction factors apply only to undegraded fibres. If the fibres have been degraded during processing, different corr
18、ection factors may be necessary. The methods described in this series apply for single determinations; at least two determinations should be made on separate samples, further determinations can be made where desired. Before the analyses are carried out, all fibres in the mixture should be identified
19、. For the purposes of confirmation, it is recommended that alternative methods be used in which the component that would have made up the residue when using the standard method is dissolved first, unless this is not technically possible. Where practically possible, the components of a mixture are to
20、 be manually separated if the method described in ISO 1833-1:2006, Annex B is to be primarily used instead of the chemical analytical methods described in the other parts of ISO 1833.

DIN EN ISO 1833-2:2011-01 EN ISO 1833-2:2010 (E) 3 Introduction The methods of quantitative analysis of mixtures of
41、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. It can be used for all textiles whose component fibr
42、es 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 capable of being unravelled and made up of yarns of dif
43、ferent 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 different test specimens, component (a) is dissolved
44、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 the third component (c) is calculated by difference.
45、 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 the component (a) is calculated from the loss in ma
46、ss. 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 dissolved from the first test specimen and two compone
47、nts (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 components is removed, after which the insoluble r
48、esidue 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 ma
49、ss. 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 other 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 mi
