摘　　要：用环氧氯丙烷、二甲胺、乙二胺合成了阳离子改性剂聚环氧氯丙烷-二甲胺,并将其用于棉织物的阳离子改性,然后用活性染料进行无盐染色.确定了阳离子改性剂对棉织物的最佳改性工艺及改性棉织物的染色工艺.结果表明,棉织物经改性后,可用于活性染料的无盐染色,上染率和固色率均高于常规染色.The cationic modifier polyepichlorohydrin-dimethylamine was synthesized by epichlorohydrin, dimethylamine and ethylenediamine. It was applied in cationic modification of cotton fabric, Then the modified cotton fabric was salt-free dyed with reactive dyes, The optimal cationic modification of cotton fabric and dye- ing process of cationic agent modified cotton fabric were determined. The results showed that the modified cotton fabric could be applied in salt-free dyeing with reactive dyes, The exhaustion rate and fixation rate of modified fabric were higher than those of the traditional dyed fabric.
