摘　　要：针对棉织物姜黄染料直接染色表面色深度(K/S值)低、染色牢度差的问题,利用壳聚糖与2,3-环氧丙基三甲基氯化铵制备壳聚糖季铵盐阳离子改性剂,并对棉织物进行改性和染色。通过单因素和正交试验,确定改性后棉织物姜黄染料染色优化工艺为:在浴比为1∶40条件下,姜黄染料用量为7.5%(omf)、染色温度为50℃、染色时间为30 min。经改性后的棉色织物皂洗牢度、摩擦牢度较未改性棉织物普遍提高了0.5～1.0级,达到了Oeko-Tex标准100要求。In view of low color depth （K/S value） and poor color fastness of natural dye curcumin on cotton fabrics, cationic modification is carried out with chitosan quaternary ammonium salt, which is prepared from chitosan and （2,3-epoxypropyl） trimethylammonium chloride. The dyeing processes of curcumin on modified cotton fabrics are optimized by single and orthogonal tests, and the best conditions are defined as follows： dyeing liquor ratio 1：40 , 7.5% （omf） curcumin, 50℃ for 30 min. The color fastness to soaping and rubbing of the modified cotton fabric are 0.5 - 1 level higher than those of the unmodified fabric, the former can meet the standard of Oeko-Tex Standard 100.
