标准范围

本文件规定了一种方法，使用甲酸和氯化锌的混合物，在去除非纤维物质后，测定由以下物质制成的纺织品中粘胶、某些类型的铜、莫代尔或lyocell的质量百分比:-粘胶纤维、某些类型的cupro、modal或lyocell、，具有-棉花。本文件最初专门针对粘胶、某些类型的cupro、modal或lyocell与棉花的混合物制定，也适用于与聚丙烯、弹性烯烃和三聚氰胺的混合物。重要事项-如果发现存在cupro或modal或lyocell纤维，则应进行初步测试，以确定其是否可溶于试剂中。该方法不适用于棉花遭受广泛化学降解的混合物。当粘胶纤维、cupro纤维、莫代尔纤维或lyocell纤维由于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可溶时，本标准不适用。

This document specifies a method, using a mixture of formic acid and zinc chloride, to determine the mass percentage of viscose, certain types of cupro, modal or lyocell, after removal of nonfibrous matter, in textiles made of mixtures of— viscose, certain types of cupro, modal or lyocell,with— cotton.This document has been initially specifically established for mixtures of viscose, certain types of cupro, modal or lyocell with cotton, it is also applicable to mixtures with polypropylene, elastolefin and melamine.IMPORTANT — If a cupro or modal or lyocell fibre is found to be present, a preliminary test is 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. It is not applicable when the viscose, cupro, modal or lyocell fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely.
