摘　　要：合成了棉用阳离子改性剂聚乙烯胺羧酸化合物,利用改性剂中大量的—NH3+离子,以消除活性染料与棉织物的负离子相斥效应,从而达到低盐或无盐染色。结果表明,棉织物预处理后的强力、白度虽略有下降,但活性染料无盐染色后的各项色牢度均达到要求。Cationic finishing agent of polyamino carboxylic acids compound is synthesized and applied to cotton cationic modifi- cation. By using large amounts of --NH3 ＋ ions in finishing agent to eliminate ionic repulsion effect between reactive dyes and cotton fabric, the low-salt or salt-free dyeing effect can be achieved. The results show that strength and whiteness of the pre- treated cotton fabric decrease, and color fastness of the salt-free and reactive dyed fabric can meet the requirements.
