摘　　要：采用自制阳离子助剂WLS-20先将棉织物改性,然后用活性染料对改性棉织物进行无盐染色,最后采用新配制的WLS-20溶液或改性使用过的WLS-20残液对染色棉织物进行固色处理。通过与未改性棉织物传统活性染料有盐染色工艺的对比发现,WLS-20助剂既可作为棉织物的改性剂,实现活性染料无盐染色;又可作为固色剂,提高染色产品的色牢度;且可重复利用改性使用过的WLS-20残液对染色棉织物进行固色处理,其固色效果与新配制的WLS-20固色效果相当。In this paper, cotton fabrics are modified by using self-made cationic modifier WLS-20, then reac- tive dyes are chosen to dye the modified cotton fabrics, at last, new prepared WLS-20 solution or WLS-20 solu- tion which has been used in modification process is applied in the fixation process of dyed modified cotton fabrics. Compared with the traditional dyeing process of reactive dyes in the presence of salt for unmodified cotton fabrics, it is found that WSL-20 can not only be used as modifier to realize dyeing without salt for reactive dyes, it also can be used as fixing agent to improve color fastness of fabrics; Meanwhile, it is found that WLS-20 solution can be reused, which means WLS-20 residual solution from modification process can be used in the fixation process a- gain, and the fixing effects are the same with that using new prepared WLS-20 solution in fixation process.
