真丝织物新型抗皱技术研究

Study of the New Anti-wrinkle Technology for Silk Fabric

为考察乙烯基单体的微波聚合对真丝抗皱性能的影响,选择了五种乙烯基单体(VAM、MMA、MA、St、AA)处理真丝织物;采用微波聚合法探讨了乙烯基单体及混合物对真丝织物的折皱回复角、白度、毛细管效应的影响。结果表明,在微波作用下乙烯基单体能在真丝纤维上发生聚合反应,能很好地改善织物的抗皱性,且对织物的白度、毛效和手感的影响较小。最优处理工艺为:单体质量浓度20%,VAM∶St质量比1∶0.7,快速渗透剂T 2.5%,引发剂KPS 0.8%,AA为0.05%,浴比1∶30,中高温微波3min。

Five kinds of vinyl monomers（VAM, MMA, MA, St and AA）were used to finish silk fabric by microwave polymerization in order to study the influences of microwave.polymerization of vinyl monomers and its blends on the wrinkle resistant performances of silk fabric. The influences of vinyl monomers and its blends on the wrinkle recovery angle, whiteness and capillary effect of silk fabric were discussed. The results showed that the polymerization reactions of vinyl monomers were proceeded on the silk fiber under the ac- tion of microwave polymerization. The fabric winkle resistance was improved. It had little influences on the whiteness, capillary effect and hand feeling. The optimal modification process was monomers concentration of 20%, mass ratio of VAM：St 1 ： 0. 7, emulsifier T of 2. 5 %, initiator KPS of 0. 8 %, AA of 0. 05 %, bath ratio of 1：30, high microwave temperature and time of 3 min.
