摘要
探讨了植物靛蓝对棉纱的轧染工艺,其优化的还原工艺参数为:靛蓝∶烧碱∶保险粉用量比为2∶3∶9,还原温度45℃,时间20 min.与合成靛蓝相比,植物靛蓝还原用保险粉的用量要增加50％左右.植物靛蓝优化的轧染工艺为:NaCl质量浓度为60 g/L,浸轧时间20 s,氧化时间2min,浸轧次数12 ～14次.合成靛蓝的轧染工艺为:浸轧时间为20 s,氧化时间为3 min,浸轧次数12～14次.植物靛蓝与合成靛蓝染色纱线的皂洗牢度相当.
Abstract
Pad dyeing of cotton fabric with vegetable indigo is studied. The results show that the optimum reduction process is the ratio of plant indigo: sodium hydroxide: sodium dithionite of 2:3:9, reduction at 45℃ for 20 min. The amount of sodium di-thionite increases by 50% compared with that of synthetic indigo process. The optimum pad dyeing process for vegetable indigo is the concentration of NaCI 60 g/L, dyeing time 20 s, oxidizing time 2 min, padding 12 ~ 14 times. The optimum pad dyeing process for synthetic indigo is dyeing time 20 s, oxidizing time 3 min, padding 12 ~ 14 times. The soaping fastness of cotton yarns dyed with vegetable indigo is similar to that with synthetic indigo.
