|
摘要
本文基于锦纶与氨纶在不同溶剂中溶解性的差异,探讨用化学溶解法测定锦纶与氨纶混纺比的可行性与使用何种溶剂进行溶解的最优性。采用FZ/T 01095-2002的手拆法和20%盐酸法、GB/T 2910.20-2009的二甲基乙酰胺法、GB/T 2910.7-2009的80%甲酸法分别测定锦氨织物的混纺比,并对比这几种方法各自的优劣特点。结果表明,20%盐酸法的测试数据与拆分法相差只有0.04%,标准偏差0.04,置信界限为0.05%,操作简便,准确度与精密度较高,完全能够满足锦氨混纺织物纤维含量定量分析的要求。
In this paper,based on the difference in solubility of nylon and spandex in different solvents,this paper discussed the feasibility of determining the blend ratio of nylon and spandex by chemical dissolution method and the optimum solvent for solvent dissolution. The blending ratio of the nylon and spandex fabric was determined by the split method and the 20%HCL(FZ/T 01095-2002),the dimethylacetamide(GB/T 2910.20-2009),and the 80% formic acid(GB/T 2910.7-2009).The results show that the difference between the test data and the split method of 20% HCL is only 0.04%,the standard deviation was 0.04,and the 95% confidence limit was 0.05%. The dissolution method of 20% HCL is easy to operate with accuracy and precision,it can fully meet the requirements of quantitative analysis of nylon and spandex fiber content.
