研究了用己二醇二丙烯酸酯为接枝单体、过硫酸铵(APS)为引发剂对真丝的接枝共聚反应,分析了接枝率的影响因素,并测试了改性真丝的主要应用性能.结果表明:乳液和乙醇 /水为溶剂的2种体系都能在真丝上获得较高接枝率.对于乙醇 /水体系v(乙醇)∶v(H2O)=1∶1,接枝单体20～30g/L,2 %甲酸4ml,引发剂APS0.5g/L,65～70℃接枝60min的接枝率高.改性后真丝的断裂强度、延伸度、吸湿性能都可获得改善,对酸、碱的溶解性提高,但染色性能提高不明显,对泛黄性改善一般
The graft copolymerization of silk with hexanediol diacrylate as grafting monomer and ammonium persulfate (APS) as initiator was studied. The factors affecting the grafting degree were analyzed. The main applications of the modified silk The results showed that both of the two systems with emulsion and ethanol / water as solvent could obtain higher grafting rate on silk.For the ethanol / water system v (ethanol): v (H2O) = 1: 1, The grafting rate of 20 ~ 30g / L, 2% formic acid 4ml, initiator APS 0.5g / L, grafting at 65 ~ 70 ℃ for 60min was improved.The breaking strength, elongation and hygroscopicity of modified silk could be improved , On the acid, alkali solubility increased, but the dyeing performance is not obvious, to improve the general yellowing
