摘　　要：采用植酸钠作为双蛋白纤维(大豆蛋白/酪素蛋白/聚乙烯醇)活性染料染色促染和固色助剂,探讨了植酸钠用量、氯化钠用量、植酸钠加入方式、染色时间、染色温度对染色效果的影响,比较了植酸钠染色工艺和常规染色工艺对染色效果的影响,测试了染色纤维的牢度.研究结果表明,植酸钠可在染色初始阶段一次投入,但用量较多,为100 g/L左右;也可采用10 g/L氯化钠和10 g/L植酸钠的混合物作为活性染料染色的促染和固色碱剂,植酸钠加入方式为在始染时加入1/3,升温至60℃,加入剩余的2/3,60℃保温60 min,染色织物的染色效果及染色牢度与常规染色工艺接近.Sodium phytate was used as an accelerant and fixing agent for reactive dyeing of double pro- tein fibers. The influences of sodium phytate concentration, dosage of sodium chloride, input mode, dyeing temperature and time on dyeing performance were investigated. The influence of sodium phytate dyeing meth- od on dyeing performance was compared with conventional reactive dyeing method. The color fastness of dyed fibers was also tested. The results showed that sodium phytate could be added once at the initial stage of dyeing, however, the dosage of sodium phytate was more and reached up to 100 g/L. The method of addi- tion of sodium chloride 10 g/L and sodium phytate 10 g/L to the dyeing system also be used, the optimal addi- tion method for sodium phytate was input 1/3 at the beginning and then the dye bath was heated up to 60 ℃, and the other 2/3 of sodium phytate was input and the dye bath was held at 60 ℃ for 60 min. The dyed fab- rics were found to have the same K/S value and color fastness with the conventional reactive dyeing method.
