摘　　要：以葡萄糖、二氧化硫脲以及甲酸钠作为硫化染料的还原剂。通过单因素实验,分别探讨染料质量浓度、还原剂质量浓度、氢氧化钠质量浓度等对硫化染料染纱线效果的影响,并进一步通过正交实验优选染色工艺配方上染纱线。测试纱线耐皂洗色牢度、色差、K/S值、染液的还原电位变化以及废水COD。实验结果表明,甲酸钠可以替代硫化钠作为液体硫化黑染料的还原剂,在液体硫化黑110 g/L、甲酸钠44 g/L、氢氧化钠42 g/L时,染色纱线能获得很好的染色效果,并减少了生产中硫化氢气体的释放以及含硫废染液的产生。Glucose,thiourea dioxide and sodium formate were used as reducing agents for sulfur dyes.Through the single factor experiment,the effects of the mass concentration of dye,the mass concentration of reducing agent and the mass concentration of sodium hydroxide on the dyeing effect of sulfur dyes on the yarn were discussed,and the dyeing process formula was further optimized by orthogonal experiment.The color fastness to soaping,color difference,K/S value,reduction potential of dye solution and COD of wastewa⁃ter were tested.The experimental results showed that sodium formate could replace sodium sulfide as a re⁃ducing agent for liquid fluidized black dyes.When liquid sulfur black was 110 g/L,sodium formate was 44 g/L,sodium hydroxide was 42 g/L,the dyed yarn could obtain good dyeing effect,and reduce the release of hydro⁃gen sulfide gas and sulfur-containing waste dye liquid in production.
