Dyeing Behavior of Yak Hair Fiber Treated with Microwave Low Temperature Plasma

The scales on the surface of yak hair fiber act as barriers during the dyeing process. In order to solve the scale problem and to improve the dyeability of yak hair, yak hair fiber was treated by microwave low temperature plasma （MLTP） in this study. The weight loss and the dyeing properties of the yak hair fiber modified by MLTP were investigated. Scanning Electron Microscopy （SEM） photographs were taken to observe the changes in the surface shape of yak hair fiber before and after treatment. Results showed that after MLTP treatment, the scale structure of yak hair was weakened and damaged greatly and the noticeable changes on the surface shape took place. At the same time, a significant improvement in dyeing properties of yak hair fiber was exhibited.     

开发羊绒细号纱针织产品的研究

为了开发细号羊绒纱针织产品，选用不同线密度的羊绒纱、棉纱、Ｔ／Ｃ混纺纱、涤纶低弹丝和丙纶长丝在单面圆形纬编机上进行了编织试验。作了上机对比及交织试验，测出了各纱线的强度、最大伸长率、对成圈机件的摩擦系数、最大喂纱张力、最小最大线圈长度。最大允许喂纱张力及最大最小线圈长度之差可综合评价线线的可编织性。羊绒纱的摩擦系数普遍较大，而其强度还不及棉纱的一半，最大允许喂纱张力仅为涤纶纱的１／５。羊绒纱的最小线圈长度为２．８～３．５ｍｍ，最大线圈长度能够测出，说明羊绒纱的可编织性较差。试验表明，用单面纬编机生产以羊绒为正面添纱、交织纱在织物反面的添纱组织，具有羊绒效果且服用性能良好。为了顺利地进行生产，对编织工艺、成圈过程中各阶段纱线的受力情况、上机工艺参数、机器选择和染色工艺等作了分析。
