标准范围

ISO 1833-21:2006规定了一种使用环己酮测定由醋酸盐、三醋酸盐、氯纤维、某些改性丙烯酸酯、某些弹性纤维和羊毛、动物毛、丝绸、棉、铜、莫代尔、粘胶、聚酰胺、丙烯酸和玻璃纤维的二元混合物制成的纺织品中去除非纤维物质后的氯纤维、改性丙烯酸、弹性纤维、醋酸盐和三醋酸盐百分比的方法。如果存在变性丙烯酸树脂或弹性纤维，则应进行初步试验，以确定纤维是否完全可溶于试剂中。还可以使用ISO 1833-13或ISO 1833-17中所述的试验方法分析含有氯纤维的混合物。

ISO 1833-21:2006 specifies a method, using cyclohexanone, to determine the percentage of chlorofibre, modacrylic, elastane, acetate and triacetate, after removal of non-fibrous matter, in textiles made of binary mixtures of acetate, triacetate, chlorofibre, certain modacrylics, certain elastanes and wool, animal hair, silk, cotton, cupro, modal, viscose, polyamide, acrylic and glass fibre.Where modacrylics or elastanes are present, a preliminary test should be carried out to determine whether the fibre is completely soluble in the reagent.It is also possible to analyse mixtures containing chlorofibres by using the test methods described in ISO 1833-13 or ISO 1833-17.
