标准范围

ISO 1833-6:2007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，测定由粘胶或一些铜纤维、莫代尔纤维和lyocell纤维与棉花的二元混合物制成的纺织品中棉花的百分比。如果发现存在cupro或modal或lyocell纤维，则应进行初步试验，以确定其是否可溶于试剂中。该方法不适用于棉遭受广泛化学降解的混合物，也不适用于粘胶纤维、铜纤维、莫代尔纤维或lyocell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可溶的混合物。

ISO 1833-6:2007 specifies a method, using a mixture of formic acid and zinc chloride, to determine the percentage of cotton, after removal of non-fibrous matter, in textiles made of binary mixtures of viscose or some cupro, modal and lyocell fibres with cotton.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, 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.
