摘　　要：选用甲基丙烯酰胺(MAA)作为真丝纱线的接枝增重单体,探讨影响增重率的各种因素,得出了接枝增重的优化工艺:单体MAA浓度为60%(owf)、引发剂KPS 4.74%(对单体重)、甲酸调节pH=3、非离子渗透剂A4g/L、浴比1∶20、80℃反应90 min;真丝纱线接枝增重后,纤维表面变粗糙。Silk yarn was grafted with methyl acrylamide（MAA） as the grafting monomer,and the factors influencing the weighting percentage of the silk yarn were investigated.The optimized process was as followed ：50% of MAA（o.w.f）、4.74% of KPS（relating the monomer weight）、pH value 3 adjusted with formic acid、non-ionic penetrant A 4g/L,bath ratio 1∶20、and reaction at 80℃ for 90min;The surface of the silk fiber after grafting became coarser.
