摘　　要：为了拓展植物靛蓝在羊毛织物染色中的应用,采用葡萄糖作为还原剂对植物靛蓝进行还原,优化了还原工艺和对羊毛染色的工艺条件,测试了染色后羊毛织物的性能。结果表明,葡萄糖6 g/L,氢氧化钠2 g/L,还原温度60℃,还原时间10 min,25℃时对羊毛织物染色10 min,氧化10 min,重复3次,染色羊毛织物K/S值达到28.56,耐光色牢度和耐臭氧色牢度为4级,耐干摩擦色牢度为2~3级,强力损失率为9.86%,染色前后羊毛纤维的结晶结构没有变化。In order to expand the application of plant indigo in wool fabric dyeing,using glucose as a reducing agent,the reduction and dyeing conditions are optimized,and the properties of dyed wool fabric are tested.The results show that under glucose dosage of 6 g/L,sodium hydroxide dosage of 2 g/L,reduction temperature of 60℃,reduction time of 10 min,when the wool fabric is dyed for 10 min at 25℃,oxidized for 10 min,repeats 3 times,the K/S value of the dyed wool fabric reaches 28.56,the color fastnesses to light and ozone are Grade 4,the color fastness to dry rubbing is Grade 2-3,and the strength loss rate is 9.86%.The crystal structure of wool fiber has no change before and after dyeing.
