标准摘要
[中文适用范围]： ISO 1833 的这一部分规定了一种方法，使用锌酸钠来测定由粘胶纤维或大多数当前铜氨纤维或莫代尔纤维的二元混合物制成的纺织品中去除非纤维物质后粘胶纤维、铜氨纤维或莫代尔纤维的百分比纤维和——原棉、精洗棉、精洗棉或漂白棉。 如果存在铜氨纤维或莫代尔纤维，应进行初步测试，看看其是否可溶于试剂。 该方法不适用于棉花已遭受广泛化学降解的混合物，也不适用于粘胶纤维、铜氨纤维或莫代尔纤维因存在某些无法完全去除的永久性整理剂或活性染料而变得不完全溶解的情况。 [外文原描述]： ISO 1833-5:2006 specifies a method, using sodium zincate, to determine the percentage of viscose, cupro or modal fibre, after removal of non-fibrous matter, in textiles made of binary mixtures of viscose or most of the current cupro or modal fibres and raw, scoured, kiered or bleached cotton. Where a cupro or modal fibre is present, a preliminary test should be carried out to see whether it is soluble in the reagent. The method is not applicable to mixtures in which the cotton has suffered extensive chemical degradation, nor when the viscose, cupro or modal fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely.
