摘要
对近年来的还原糖、二氧化硫脲、-β巯基乙醇等对环境友好的还原剂在硫化染料染色中的应用进展进行了介绍。传统的以硫化钠作为还原剂的硫化染料染色工艺,其高浓度含硫废水的排放给环境带来很大的污染。而新的对环境友好的还原剂的使用可以获得与硫化钠相当的染色效果,应用前景十分广阔。
Recent years' application of environmentally friendly reducing agents such as reducing sugar, thiourea dioxide, ?mercaptoethanol, etc. to the dyeing with sulfur dyes are discussed, and the dyeing result achieved by these reducing agents are comparable to that by sodium sulphide.
