壳聚糖(CS)是甲壳素N-脱乙酰基的产物.由于其来源丰富,且为天然高分子,具有生物相容性、安全性、微生物降解性等优良的性能从而被各行各业广泛关注.在纺织领域,随着壳聚糖较好的抗菌活性和抗折皱性能被开发,人们对其应用研究近年来十分活跃.
本文主要研究壳聚糖用于真丝绸织物的整理,首先分析了化学接枝法的整理效果,即采用浸轧焙烘的方法将其附着到织物上;同时对照研究了酶促接枝法催化壳聚糖在真丝表面功能化改性效果,即借助于酪氨酸酶,将壳聚糖接枝到酶促催化氧化的真丝纤维上,并对处理后织物进行染色性能、折皱回复性、强力和抗菌等性能测试.
研究表明,化学交联法整理后真丝织物的抗皱性有所提高,且具有良好的断裂强力和染色性能,但与此同时织物的白度有所下降,且处理过程中存在着化学污染及热污染;采用酪氨酸酶催化交联后,壳聚糖的接枝率有了一定的提高,织物抗皱性进一步得到了提升,同时由于处理工艺条件温和、步骤简单,且酪氨酸酶的生物降解性更确保了此法的环保性.综上表明,酪氨酸酶在催化真丝改性中具有潜在的应用前景.

Chitosan (CS) is acetyl chitin N-to take off the product. Because of its rich source, and for natural polymer, has the biological compatibility and security, microbial degradation of excellent performance by all walks of life to attention. In the textile field, with chitosan good antibacterial activity and photographs by development of performance, people on the application study in recent years very active.
This paper makes a study of the chitosan used for pure silk fabric collection, first analysis of the chemical graft copolymerization of finishing effect, which is a method of curing padding the attached to the fabric; At the same time control study the enzyme graft copolymerization catalytic chitosan in silk surface functionalization modification effect, namely by tyrosinase, will chitosan grafted to the enzyme catalytic oxidation of real silk fiber, and after the treatment of fabric dyeing performance, wrinkles resilience, strength and antibacterial properties test.
Studies show that chemical crosslinking method after finishing silk fabric wrinkle resistance improved, and has good breaking strength and the dyeing performance, but at the same time white degree of fabric has dropped, and processing process there are a chemical pollution and thermal pollution; The tyrosinase catalytic crosslinking, chitosan grafted rate had certain improve, fabric wrinkle resistance further improved, and because the process mild conditions, simple steps, and tyrosinase biodegradation more to ensure that this method environmental protection sex. All show that tyrosinase in catalytic silk modification has potential application prospect.
