易洗涤活性染料轧染染色性能研究

摘要

采用所合成的活性染料对棉织物进行轧染染色性能研究,讨论了固色碱剂和汽蒸时间对染色效果的影响.结果表明:该染料具有较好的匀染性,提升力中等,染色牢度优良.通过对染色织物采用不同的皂洗温度进行后处理,考察了染料的易洗涤性.%The pad dyeing performance of synthesized reactive dyes on cotton fabric was investigated. The effects of fixation alkaii and steaming time on the dyeing performance were discussed. The results showed that the synthesized reactive dyes had good levelness and color fastness, and medium build-up. At the same time, the easy washing-off properties of the reactive dyes were investigated through treating the dyed fabrics at different soaping temperature.
