牦牛毛的低温等离子体表面改性

为了改善牦牛毛纤维的表面性能,提高其染色性能,研究了低温等离子体表面改性处理牦牛毛对其表面性能的影响。通过SEM分析了处理前后纤维表面形貌的变化,探讨了经氧气和空气等离子体分别处理后,牦牛毛的拉伸强度和染色性能的变化。结果表明,低温等离子体表面改性处理能够刻蚀牦牛毛纤维表面的鳞片,而且空气等离子体的刻蚀效果优于氧气等离子体的刻蚀效果;等离子体处理提高了牦牛毛纤维的染色速率以及染色上染率,同时保持其物理性能即拉伸强度不变。

Surface modification of yak hairs by low temperature plasma

In order to improve the surface performance of yak hair fibers and enhance their dyeing property,the influence of low temperature plasma treatment of the yak hairs on their surface was studied.Scanning electron microscope(SEM) was used to analyze the morphological change of the fibers after treatment and investigated the tensile strength and dyeing property of the yak hair fibers treated by oxygen-plasma and air-plasma respectively.The results indicate that the surface scales of yak hairs are etched by the low temperature plasma treatment,and in the case of etching effect,air plasma is better than oxygen plasma.At the same time,plasma treatment has enhanced the dyeing rate and dye uptake of the yak fibers with the physical properties such as tensile strength remained.
