摘　　要：针对活性染料利用率低,染深色及盐用量多的问题,利用自制阳离子明胶蛋白助剂对CVC织物进行阳离子化改性,优化出有利于提高活性染料吸附上染性能的最佳改性工艺条件,并且研究了改性CVC织物活性染料无盐染色的性能.结果表明,改性CVC织物无盐染色可获得比未改性CVC织物常规加盐染色更高的上染百分率、K/S值、固色效率和皂洗牢度,但是摩擦牢度有轻微降低,需要进一步研究.CVC fabric is modified with sele-made cationic gelatin protein agent.Then the best modified process conditions are optimized which are conducive to improving the dyeing performance of reactive dyes.And the salt-free dyeing properties of modified CVC fabric are researched.Compared with the unmodified CVC fabric dyeing with salt,the salt-free dyeing modified CVC fabric demonstrates a higher dyestuff up-take,K/Svalue and fixation rate.The fastness to soaping is improved while the rubbing fastness slightly decreases,which needs further study.
