One-bath dyeing of cotton/milk protein fiber blended yarn

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 yarns 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).
