摘　　要：用自主制备的高分子聚羧酸共聚物、螯合分散稳定剂和烷基糖苷(简称APG)、还原促进剂、表面活性剂等5种净洗剂组分进行复配,研究不同复配体系对一浴染色涤棉织物净洗效果的影响,并以净洗浴中染料对棉、涤的沾色牢度色差值,净洗后织物的摩擦色牢度等作为评价指标,通过单因素试验确定还原净洗剂ST233复配体系的优化工艺参数。还原净洗剂ST233各组分按质量百分比计为:高分子聚羧酸共聚物25%、螯合分散稳定剂5.6%、APG 40%、还原促进剂1.5%、表面活性剂AEO-7 2.5%、去离子水25.4%;净洗浴工艺条件为2g/L的NaOH溶液,净洗温度90℃,净洗时间5min,在该条件下对涤棉织物净洗处理,织物各项色牢度得到显著提高,且对涤、棉贴衬的沾色少。In order to improve the cleaning effect of the polyester / cotton fabric in one bath dyeing method, five kinds of washing agents of self prepared polymer poly carboxylic acid copolymer, chelating dispersant and APG, reducing accelerator, surface active a- gent were compounded and applied to the dyed polyester / cotton fabric. The effects of different compounded system on cleaning of the dyeing polyester / cotton fabric were studied. The optimal process was determined based on the color fastness of dyes to cotton and polyester in bath cleaning and the color fastness to rubbing of the fabric after washing by single factor experiment. The optimum com- pound system was the poly carboxylic acid copolymer 25%, chelating dispersant 5.6%, APG 40%, reducing accelerator 1.5%, surface active agent AEO-7 2.5 % and DI water 25.4 %. The optimum washing process was as follows： NaOH concentration 2 g/L, tem- perature 90 ℃, and time 5 min. The color fastness to rubbing of the fabric after washing was greatly improved and the white staining of dyes to cotton and polyester in bath cleaning was less.
