摘　　要：分别探究Na_(2)CO_(3)、NaHCO_(3)和NaHCO_(3)/Na_(2)CO_(3)缓冲溶液对废旧真丝织物脱胶率的影响,以确定3者的脱胶pH,探求优化工艺。经完全脱胶后的丝素纤维在溴化锂和三元溶液两种溶解方法下进行溶解,并对二者溶解废旧真丝织物时的浓度、浴比、温度和时间进行探究,确定优化溶解工艺为:溴化锂浓度9 mol/L、浴比5∶100、温度75℃、时间60 min。用丝素蛋白增重液对真丝织物进行增重处理,优化的增重工艺为:整理液质量浓度10 g/L、浴比1∶40、温度60℃。测试处理后真丝织物的颜色和性能。在不影响真丝织物正常表观颜色和基础特性的前提下,真丝织物可以获得5.7%左右的增重率。The effects of Na_(2)CO_(3),NaHCO_(3)and NaHCO_(3)/Na_(2)CO_(3)buffer solutions on the degumming rate of waste silk fabrics were investigated separately in order to determine the optimal degumming pH of the two buffer solutions to realize the optimized process.The completely degummed silk fibers were dissolved in lithi⁃um bromide and ternary solution,and the concentration,bath ratio,temperature and time of the two dissolved waste silk fabrics were investigated to determine the optimized dissolution process of lithium bromide concen⁃tration of 9 mol/L,bath ratio of 5∶100,temperature of 75℃,and time of 60 min.Silk fabrics were weighted using a silk protein weighting solution,and the optimal weighting process was 10 g/L finishing solution mass concentration,bath ratio 1∶40,and temperature 60℃.The treated silk fabrics were tested in terms of color and properties,and a silk fabric with about 5.7%weight gain could be obtained without affecting the normal apparent color and basic properties of silk fabrics.
