摘要

Cotton's dark-dyeing with sulfur black was studied in this paper. It's a simple process for cotton because of no bleaching, just only desizing, scouring and dyeing with two steps in one-bath. Through adjusting technical parameters, the optimum conditions were obtained: NaOH 6 g/L, Na_2SiO_3 2 g/L, scouring agent 2 g/L, JFC 1 g/L, sulfur black 14%, Na_2S 16%, carbamide 2 g/L, bath ratio 1:20, scouring and dyeing at 95°C for 45 min and 35 min separately. Compared the simple process with the traditional one, the former can get similar performance on dyeing. In addition, the simple process showed such advantages as short time, high efficiency, reduced energy consumption, relatively low water consumption and reduced sewage emission.
