无引发剂接枝聚合对丝素蛋白纤维性能的影响

The Effect of Initiationless Graft Copolymerization on Silk Fibre Properties

通过对不同接枝率的丝素蛋白纤维的耐水洗性、吸湿性、力学性能、热稳定性及染色性等的研究和分析 ,探讨了无引发剂条件下甲基丙烯酸甲酯 (MMA)与丝素蛋白纤维接枝聚合对丝素蛋白纤维性能的影响。结果表明 :接枝聚合后丝素蛋白纤维有良好的耐水洗性 ,力学性能、热稳定性均有提高 ,吸湿性下降不明显 ,染色性有所提高 ,接枝率 2 6 %左右吸色深度最大。

The paper mainly studies the influence of methyl methacrylate initiationless graft copolymerization on silk fibre properties at different graft yield.These grafted fibres washing resistance,wettability,mechanical property,heat stability and dyeability are measured.The results showed that grafted silk fibresmechanical property and heat stability both increased,but wettability decreased a little.When graft yield is twenty-six percent,their dyeability reaches maximum.Meanwhile,the washing resistance is good.The silk original advantages remain well.
