对再生切片中杂质元素来源及其对可纺性影响的探究

摘要

This thesis uses X-ray fluorescence spectrometer to measure the contents and varieties of impurity elements in the discarded textiles and the renewable particles .Besides , it analyzes the source of all kinds of impurity elements and discusses its negative influence on the spinnability .The results show that these impurity elements are mainly from the additives which are used in the manufacturing process of primary textiles and the impurities in the stacking .These impurities affect the performances of renewable particles and reduce the spinnability of renewable particles .%　　利用 X-荧光光谱仪对废旧纺织品及其再生切片中杂质元素的含量和种类进行测试，并分析了各种杂质元素的来源，探讨了各杂质元素对后期纺丝可能产生的不利影响。结果表明，这些杂质元素主要来自于原生纺织品在制造过程中使用的添加剂及其在堆放过程中沾染的杂质，这些杂质影响了再生切片的各项性能指标，降低了再生切片的可纺性。
