染色对山羊绒纤维拉伸性能与表面形态结构的影响

对高温与低温染色工艺下的山羊绒纤维,利用电子单纤维强力仪测试其强伸性能,利用扫描电子显微镜对染色前后纤维的表面形态进行观测.实验结果表明:低温染色纤维的强伸性能比高温染色纤维的强伸性能好,特别是深色染色更为明显.通过扫描电子显微镜可以看出:低温染色工艺中纤维鳞片表面的损伤比高温染色纤维要少得多.

Influence of dyeing on tensile properties and surface morphology of cashmere fiber

The tensile property of dyed cashmere under high temperature and low temperature respectively was tested using single fiber tensile tester.The surface structure of cashmere and dyed cashmere was compared by the scanning electron microscope(SEM).The result showed that the tensile property of cashmere was better under low temperature dyeing than that of high temperature dyeing.The SEM pictures showed that the damage on the surface scale of cashmere was less under low temperature dyeing process compared with t...
