摘　　要：采用N2微波低温等离子体对牦牛毛进行处理,探讨了微波低温等离子体对牦牛毛鳞片结构的削弱作用,研究了处理工艺对牦牛毛纤维失重率和染色性能的影响,利用扫描电子显微镜(SEM)观察了处理前后其表面的物理形态变化。结果表明,经微波低温等离子体处理后的牦牛毛纤维表面鳞片结构被大大削弱,染色性能显著提高,相同时间内上染率提高20%以上。In this study, microwave low temperature plasma (MLTP) is used to modify yak hairs. The etching effect of MLTP on surface scales of yak hairs is investigated. The effect of the treatment process on weight loss and the dyeing property of the yak hair fibers are also studied. Scanning Electron Microscopy (SEM) is used to observe the changes in the surface structure of the yak hair fibers after treatment. The results indicated that after MLTP treatment, the scale structure of yak hair fibers are weakened and damaged greatly; which enhanced the dyeing property of the fibers significantly. Dye uptake is increased by 20%.
