标准摘要
[中文适用范围]： 本文件规定了使用蚁酸和氯化锌测定混纺纺织物中去除非纤维物质后的粘胶或某些类型的铜氨、莫代尔或莱赛尔纤维质量百分比的方法。这些混合物由粘胶或某些类型铜氨、莫代尔或莱赛尔纤维与亚麻纤维组成。本文件不适用于亚麻纤维发生严重化学降解的混合物，也不适用于由于存在某些不能完全去除的永久性整理剂或反应性染料而导致粘胶、铜氨、莫代尔或莱赛尔纤维未能完全溶解的情况。 [外文原描述]： This document specifies a method, using formic acid and zinc chloride, to determine the mass percentage of viscose or certain types of cupro or modal or lyocell, after removal of non-fibrous matter, in textiles made of mixtures of — viscose or certain types of the cupro or modal or lyocell fibres with — flax fibres. This document is not applicable to mixtures in which the flax fibre has suffered extensive chemical degradation, nor 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.
