摘　　要：用二氧化硫脲作还原剂将粉末硫化染料变成液体硫化染料,选择轧染工艺对针织布进行染色。对染色后的针织布进行染色效果、色牢度的测试分析。结果表明:只用二氧化硫脲质量浓度为0.5 g/L就可以得到染色效果和色牢度较好的针织布,应用前景很好。Liquid sulfur dye is made from powder sulfur dye using thiourea dioxide as reducing agent and is applied to knitted fabric through pad dyeing process. The dyeing effect and colour fastness on the knitted fabric are analyzed. The results show that better dyeing effect and colour fastness can be got only using 0.5 g/L quality concentration of thiourea dioxide, which has bright application.
