无引发剂接枝聚合对丝素蛋白纤维性能的影响

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 Effect of Initiationless Graft Copolymerization on Silk Fibre Properties

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.
