摘　　要：羊绒纤维利用氨气低温等离子体预处理后,在乙二醇二缩水甘油醚(EGDE)、戊二醛(GA)、六亚甲基二异氰酸酯(HDI)交联剂的架桥作用下分别进行丝胶蛋白在其表面的接枝改性。通过探讨羊绒的染色效果与纤维强度,优化了氨气等离子体处理条件。对比常温浸渍反应与浸轧烘两种方式对接枝的影响,优化交联剂的用量。结果表明:浸轧烘的方式要优于常温接枝,丝胶经不同交联剂在羊绒的接枝率顺序为GA﹥EGDE﹥HDI,但GA交联后纤维白度下降严重,EGDE及HDI交联绒的染色能力不受影响;抗菌和抗氧化剂测试发现,丝胶改性羊绒具备了良好的生物活性;另外,改性绒具备了较持久的耐洗牢度。Cashmere modification is achieved by the grafting of sericin using crosslinker(EGDE, GA, HDI)after following the cashmere pretreatment in ammonia low temperature plasma. Combining the dyeing effect and fiber strength of cashmere, the suitable conditions of ammonia plasma radiation to cashmere were confirmed. During the grafting process, the effect of soaking reaction at room temperature and Pad-Dry-Cure on grafting was compared,and the effect of crosslinking agent amount on weight gain was also optimized. After experiment, it was found that the method of Pad-Dry-Cure was better than that of grafting at room temperature, the grafting rate sequence of sericin was GA ﹥ EGDE ﹥ HDI, but the whiteness of sericin-cashmere decreased seriously after GA cross-linking,the fiber dyeing ability of sericin-cashmere was not affected by neither EGDE and HDI as crosslinker. The infrared spectra showed that the increase of amino groups after plasma treatment and sericin grafting, and SEM images proved that a certain amount of attachment produced on the surface of the fiber after sericin grafting. It was found that sericin modified cashmere had good biological activity by testing the antibacterial and antioxidant properties of the grafted samples. Additionally, the modified cashmere is provided with a long-lasting washing fastness.
