摘要
将柠檬酸用到蚕丝的脱胶处理中,研究了酸的质量浓度、反应温度和时间等对脱胶效果的影响,得出了最佳工艺:柠檬酸质量浓度15 g/L,温度98℃,浴比1∶60,处理时间30 min.研究了酸脱胶后蚕丝的机械性能和表面形态结构的变化,结果表明:对丝素的损伤较小,脱胶后丝的表面变得平滑.
Citric acid was used in silk degumming. The influences of acid concentration, temperature and time on the degumming were investigated. The optimum technological conditions were obtained： citric acid 15 g/L, 98℃ of degumming temperature, liquor ration 1：60, degumming time 30 min. The mechanical properties and surface morphology of degummed silk fiber were also investigated. The results showed that the citric acid degumming had little damage to silk fibroin, and the surface of degummed silk became smoother.
