摘　　要：以紫甘薯红色素水溶液为染液,采用直接染色及黄土、亚铁盐和铝盐为媒染剂对大豆蛋白复合纤维织物进行染色。通过正交试验和综合分析确定了紫甘薯红色素上染大豆蛋白复合纤维织物的最佳工艺条件为:染液质量浓度5 g/L,染液pH值3,染色温度60℃,染色时间40 min,浴比1∶40。织物经过媒染后,色牢度、色差和上染百分率都有明显提高,预媒染与后媒染相比,预媒染效果较佳,色彩红艳,亚铁盐在后媒染中,体现出了其增色效果,上染百分率大,但上染效果不稳定且颜色发暗。This article takes three kinds of dyeing crafts and the loess,ferrous salt,the aluminum salt as mordant to dye the soybean protein woven fabrics with purple sweet potato colorant.Through the orthogonal experiments,it generalizes analysis and obtains the optimum process conditions of soybean protein fabrics.The optimum dyeing condition is 5 g/L dyeing bath,pH value 3,bath temperature 60 ℃,dyeing time 40 min and bath ratio 1∶40.The color fastness,the chromatic aberration and the dye-uptake of the dyed fabric have the distinct enhancement after treating with mordant.The pre-mordant dyeing effect is better compared with after-mordant dyeing,because the color of fabric is redder through pre-mordant dyeing.It can improve color value and dye-uptake treated with ferrous salt but unstable and darkly.
