Research on One Bath Dyeing Technology of Wool and Silk

In this paper, the one bath dyeing technology of wool and silk was studied, which were colored with neolan dye. The best dyeing conditions of homochromatic property were obtained by the optimization of the dyeing temperature and heat preservation time and the adjustment of the auxiliaries, when the wool and silk dyeing in the same bath. Experiments show that the best homochromatic property of wool and silk in one bath dyeing was obtained when the dyeing temperature was 85 degrees C-95 degrees C, the heat preservation time was 30 minutes and the amount of sodium sulphate was 20g/L.
