摘　　要：通过低温等离子体处理技术,对山羊绒纤维进行防毡缩整理.在空气条件下,制定单因素实验,研究低温等离子体处理时间对山羊绒纤维的断裂强力、断裂伸长率和摩擦性能的影响.通过扫描电子显微镜(SEM)观察改性前后纤维表面的微细结构变化.实验结果表明,经不同条件的等离子体处理后,山羊绒纤维的表面出现了不同程度的物理与化学刻蚀作用.在保证单纤维强力损失变化不大的情况下,纤维的表面防毡缩性能得到了较大的改善.当等离子体处理压强为20Pa,功率为60W时,较佳的处理时间为2min.The cashmere fibre was treated by low-temperature plasma in order to enhance its shrink-resist property.Through establishing the single factor experiment,the time effect of low-temperature plasma on breaking strength,breaking elongation and friction property of cashmere fibre is studied.The scanning electronic microscope（SEM）was used to observe the subtle changes in the surface structure of cashmere fiber before and after treatment.The results indicate that the surface of cashmere fiber presented different degrees of physical and chemical etching after treatment.The shrink-resist property of cashmere has improved greatly under the condition of the little single fiber strength loss.The optimized low-temperature plasma treatment condittion is as follows： the cabinet pressure is 20Pa,discharge power is 60W and the time is 2 min.
