摘要
采用蛋白酶对蚕丝织物进行脱胶，为提高蚕丝脱胶效果，在酶练之前对织物进行预处理，以促进丝胶膨润、软化。酶脱胶工艺的优化条件为：酶2．0-2．5g／L，pH值9～10，温度40～50℃，时间40—45min。与皂碱脱胶效果相比，采用酶脱胶工艺的蚕丝织物断裂强力、毛效与脱胶率均较高，手感较好，较柔软，仅白度稍差。
Degumming of silk fabric with protease is carried out. Pretreatment of silk fabric before degumming can promote swelling and softening of silk gum. The degumming process is optimized as follows： protease 2.0-2.5 g/L, pH value of 9 - 10, degumming at 40-50 ℃ for 40-45 min. The results show that the breaking strength, capillary effect and degumming rate of silk fabric are higher compared with those treated with soap-alkali degumming process. The degummed silk fabric has soft handle but a sliclhtlv decreased whiteness.
