摘　　要：用自制阳离子改性剂WLS对棉织物进行阳离子化改性,然后采用活性染料无盐染色.确定了阳离子改性剂WLS改性棉织物的最佳工艺条件及其染色工艺条件,评价了改性织物的染色性能,结果表明:改性棉织物采用活性染料无盐染色,可获得比未改性棉织物常规加盐染色更高的K/S值和染色牢度.阳离子改性剂WLS改性的棉织物可实现活性染料无盐染色,并适用于不同的活性染料.Self-made cationic agent WLS was applied in cationic modification of cotton fabric.the modified cotton fabric was salt-free dyed with reactive dyes.The optimal modification and dyeing technology of cationic agent WLS modified cotton fabric was determined.The dyeing behavior of modified cotton fabric was evaluated.The results showed that the modified fabric dyed with reactive dyes without salt addition had better K/S value and color fastness compared with those of the conventional salt dyed fabric.Cotton fabric modified with cationic agent WLS could be dyed with various reactive dyes without salt addition.
