National foreword This docum
5、ent (EN ISO 1833-22:2013) has been prepared by Technical Committee ISO/TC 38 “Textiles” in collaboration with Technical Committee CEN/TC 248 “Textiles and textile products” (Secretariat: BSI, United Kingdom). The responsible German body involved in its preparation was the Normenausschuss Materialprf
6、ung (Materials Testing Standards Committee), Working Committee NA 062-05-12 AA Textilchemische Prf-verfahren und Fasertrennung. For the information of the user the introduction to ISO 1833-1:2006 is given below: In general, the methods described in the different parts of ISO 1833 are based on the se
7、lective solution of an individual component. After the removal of a component, the insoluble residue is weighed, and the proportion of soluble component is calculated from the loss in mass. This part of ISO 1833 gives the information which is common to the analyses, by this method, of all fibre mixt
8、ures, whatever their composition. This information should be used in conjunction with the other parts of ISO 1833; these parts contain the detailed procedures applicable to particular fibre mixtures. Where, occasionally, an analysis is based on a principle other than selective solution, full details
9、 are given in the appropriate part. Mixtures of fibres during processing and, to a lesser extent, finished textiles may contain fats, waxes or dressings, either occurring naturally or added to facilitate processing. Salts and other water-soluble matter may also be present. Some or all of these subst
10、ances would be removed during analysis, and calculated as the soluble-fibre component. To avoid this error, 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 Annex A of this part of ISO 1833. In additio
11、n, textiles may contain resins or other matter added to bond the fibres together or to confer special properties, such as water-repellence or crease-resistance. Such matter, including dyestuffs in exceptional cases, may interfere with the action of the reagent on the soluble component and/or it may
12、be partially or completely removed by the reagent. This type of added matter may also cause errors and should be removed before the sample is analysed. If it is impossible to remove such added matter, the methods of analysis are no longer applicable. Dye in dyed fibres is considered to be an integra
13、l part of the fibre and is not removed. Most textile fibres contain water, the amount depending on the type of fibre and on the relative humidity of the surrounding air. Analyses are conducted on the basis of dry mass, and a procedure for determining the dry mass of test specimens and residues is gi
14、ven in this part of ISO 1833. The result is therefore obtained on the basis of clean, dry fibres. DIN EN ISO 1833-22:2013-07 3 Provision is made for recalculating the result on the basis of: a) agreed allowances for moisture content1), b) agreed allowances for moisture and also for 1) fibrous matter
15、 removed in the pre-treatment, and 2) non-fibrous matter (for example, fibre dressing, processing oil, or size) that can be properly regarded as part of the fibre as an article of commerce. In some methods, the insoluble component of a mixture may be partially dissolved in the reagent used to dissol
16、ve the soluble component. 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 should be corrected; correction factors for this purpose are given. These correction factors have been determin
17、ed in several laboratories by treating, in 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 during processi
18、ng. The procedures given apply to single determinations; at least two determinations on separate test specimens should be made, but more may be carried out if desired. Before proceeding with any analysis, all the fibres present in the mixture should have been identified. For confirmation, unless it
19、is technically impossible, it is recommended that use be made of alternative procedures whereby the constituent that would be the residue in the standard method is dissolved out first. If it is practicable to separate the components of a mixture manually, the method described in Annex B should be us
20、ed in preference to the chemical methods of analysis given in the individual parts of ISO 1833:2006.
