摘　　要：针对棉和牛奶蛋白纤维的染色性能差异,讨论染料、防染剂、pH值、染色温度和保温时间等工艺因素对棉/牛奶蛋白纤维混纺纱线同浴染色的影响。通过正交试验分析确定棉/牛奶蛋白纤维混纺纱线活性染料同浴染色的最佳工艺。结果表明:选择Red CN-7B、Blue CN-BL和Yellow CN-603三原色染料,在染色温度为70℃、保温时间为40 min、pH值为8、防染剂质量浓度为0.8 g/L的工艺条件下对棉/牛奶蛋白纤维纱线进行同浴染色,能得到良好的同色性及较高的上染率。Aiming at the poor dyeing property of the cotton/milk protein fiber blended yarn, the effects of process factors such as dyestuff, resist agent, pH value, dyeing temperature and time on its homochromatism were discussed. The optimum process of one-bath dyeing of cotton/milk protein fiber blended yarn with reactive dyes was determined through orthogonal experiments. The results indicate that the blended yams have obtained good homochromatism and high dye-uptake when one-bath dyeing of the yarns was performed with pH value 8, resist agent 0.8 g/L and trichromatic reactive dyes such as Red CN-7B,Blue CN-BL and Yellow CN-603 at 70 ℃ for 40 min.
