摘　　要：以PECH-amine为改性剂对棉织物改性,探讨了改性后棉织物的染色性能。结果表明,与未改性棉织物相比,改性棉织物可用直接染料和活性染料在中性无盐条件下染色,染料的上染率明显提高,活性染料的固色率提高;染相同深度时能节约染料80%以上;染色织物的各项性能符合GB 18401—2003的A类要求;染色残液能达到《纺织染整行业水污染物排放标准》(GB 4287—92)中的Ⅱ级标准,实现了染色废水中无盐且基本无染料的清洁生产目的。Dyeing behavior of cotton fabric modified with PECH-amine was investigated. The results show that compared with the unmodified cotton fabric, the modified fabric can be dyed with direct and reactive dyes without salts under neutral conditions, dye uptake is improved obviously, and the fixation rate of reactive dyes is enhanced. When dyeing the same depth of shade, 80% of dyes can be economized. The performance indexes of the dyed fabric of modified cotton have reached the requirements in class A of GB 18401--2003. The dye effluent is conformed to Level II Standard of ＂Waste Water Discharge Standard for the Textile Dyeing and Finishing Industry＂ （GB 4287--1992）. Clean dyeing whose effluent contains zero salt and little dye has been realized.
