摘　　要：天然河水净化后,需要通入氯气杀死水中的细菌、微生物,以提高自处理水的品质。染色前要脱除残余氯气,否则活性染料在残余氯气存在的水中容易被氧化。残余氯气生成的次氯酸根对活性染料的发色基团有一定消色作用。为了防止染色出现走色,探讨硫代硫酸钠脱氯的准确用量与工艺。After the purification of natural river water,chlorine gas needs to be introduced to kill bacteria and mi⁃croorganisms in the water,in order to improve the quality of self treated water.Before dyeing,residual chlorine gas should be removed,otherwise reactive dyes are prone to oxidation in water containing residual chlorine gas.The hypochlorite gen⁃erated by residual chlorine gas has a certain decolorization effect on the chromogenic groups of reactive dyes.To prevent color fading,precise dosage and process for dechloridation using baking soda are discussed.
