| 摘 要： | 为利用溶胀剂的膨化和分纤作用提高真丝织物的接枝增重率和改善织物的性能,采用不同浓度的溶胀剂U对真丝织物进行预处理,再以甲基丙烯酰胺(MAA)为单体,过硫酸钾(KPS)为引发剂对真丝织物接枝增重。选择体积分数为10%的溶胀剂U对真丝织物进行预处理,丝纤维直径由11.90μm增加至14.24μm,起到了较好的膨化和分纤作用,织物的强力、折皱回复角、白度损失也较小。与未进行预处理的真丝织物相比,用10%溶胀剂U预处理后真丝织物的接枝增重率提高,织物的强力、折皱回复角、白度得到改善。真丝织物经10%溶胀剂U预处理后进行丝纤维微观结构形貌表征:红外光谱(IR)显示丝纤维仍保持着β-折叠结构;扫描电子显微镜(SEM)观测到丝纤维表面覆盖的聚合物减少,横截面变粗,直径变大,出现分纤现象和微孔特征;X-射线衍射分析表明丝纤维的结晶度提高。

| Abstract: | To increase the weight gain of grafting on silk fabrics and improve the performance of silk fabrics by utilizing the swelling agent's swelling and defibrillation properties,different concentrations of swelling agent U were used to pre-treat the silk fabric.Then,methacrylamide(MAA) was used as the monomer and potassium persulfate(KPS) was used as the initiator to do grafting on the silk fabric.It was found that pre-treatment with swelling agent U of 10% volume fraction could increase silk fiber's diameter fr... |
