回用山羊绒纤维特征参数测定

Determination of characteristic parameters of recycled cashmere fiber

针对回用山羊绒难鉴别的问题,分别对50个原生山羊绒纱线和回用山羊绒纱线进行纤维长度测试,并对2种山羊绒纱线纤维长度测试结果进行比较,分析回用山羊绒纱线纤维长度特点;对124个回用山羊绒纱线含量进行测试,分析回用山羊绒纱线中其他纤维含量特点;并在光学显微镜下观察回用山羊绒纱线纵向形态,总结回用山羊绒纱线纤维的纵向形态特征,可为回用山羊绒鉴别和标准的制定提供参考依据。

In order to solve the problem of identifying recycled cashmere,the fiber length of fifty original and recycled cashmere yarns was tested and compared,and the characteristics of recycled cashmere yarn fiber length were analyzed.The content of 124 recycled cashmere yarns was tested,and the content characteristics of other fibers in recycled cashmere yarns were analyzed.The longitudinal morphology of recycled cashmere yarn was observed under the optical microscope,and the longitudinal morphological characteristics of recycled cashmere yarn fiber were summarized,which could provide reference for the identification of recycled cashmere and the formulation of standards.
