标准摘要
[中文适用范围]： 本文件规定了一种方法，使用二甲基乙酰胺测定去除非纤维物质后，由以下物质制成的纺织品中弹性纤维的质量百分比： ——某些弹性纤维与 — 棉、粘胶纤维、铜氨纤维、莫代尔纤维、莱赛尔纤维、聚酰胺、聚酯或羊毛纤维。 当存在丙烯酸纤维时，该方法不适用。 还可以使用 ISO 1833-12 或 ISO 1833-21 中描述的测试方法来分析含有某些弹性纤维的混合物。 [外文原描述]： This document specifies a method using dimethylacetamide to determine the mass percentage of elastane, after removal of non-fibrous matter, in textiles made of mixtures of: — certain elastane fibres with — cotton, viscose, cupro, modal, lyocell, polyamide, polyester or wool fibres. This method is not applicable when acrylic fibres are present. It is also possible to analyse mixtures containing certain elastane fibres by using the test methods described in ISO 1833-12 or ISO 1833-21.
