【摘要】 为正确把握蛋白质纤维与氨纶混纺产品的服用性能与生产工艺,需要对该类产品的混纺比进行准确的测定。以天然蛋白质纤维中的羊毛和桑蚕丝纤维为例,采用二甲基甲酰胺法、次氯酸盐法及拆分法分别对5种不同的羊毛/氨纶混纺产品和桑蚕丝/氨纶混纺产品纤维含量进行测试与对比分析,试验结果完全符合FZT 01095—2002《纺织品氨纶产品纤维含量的试验方法》和GB/T 2910.4—2009《纺织品定量化学分析第四部分:某些蛋白质纤维与某些其他纤维的混合物》的要求。且在测试中从纤维溶解过程来看,采用次氯酸钠盐法测试蛋白质纤维与氨纶纤维的含量比用二甲基甲酰胺法更为合理。为蛋白质纤维与氨纶纤维混纺产品纤维含量测试与分析提供了很好的依据。更多还原

【Abstract】 Based on the natural protein fiber of wool and silk,for example,by using dimethyl formamide,hypochlorite method and splitting method respectively for five different products and silk /spandex and wool / spandex fiber blended product content has carried on the contrast and analysis discussion,test results completely conform to the FZ / T 01095—2002 ″ the textile fiber product fiber content test method″ and GB / T 2910. 4—2009 ″textile quantitative chemical analysis the fourth part: the mixture of some protein fiber and other fibers″ requirements. And in the test from the point of fiber dissolving process, using sodium hypochlorite salt method to test the content of protein fiber and polyurethane fiber than using dimethyl formamide method is more appropriate. For protein fiber and polyurethane fiber mixed textile fiber content test and analysis provides a good basis.更多还原
