摘　　要：为改善黄麻/棉混纺织物的染色性能,实现活性染料低盐低碱染色,对黄麻/棉混纺织物阳离子改性进行研究,并探讨阳离子改性对织物染色性能的影响。通过研究获得了最佳改性工艺:Glytac质量浓度为40 g/L,氢氧化钠质量浓度为8 g/L,JFC质量浓度为2 g/L,温度为60℃,时间为45 min,浴比为1∶20。研究结果表明:黄麻/棉混纺织物经Glytac改性后用活性染料染色时,可大大减少电解质和碱的用量,降低染色温度,提高染料利用率、水洗色牢度和摩擦色牢度;在本文实验条件下,Glytac改性对日晒牢度无显著影响。In order to improve the dyeability of jute /cotton blended fabric and achieve low salt and low alkali dyeing with reactive dyes,the impact of cationic modification on the dyeability of jute /cotton blended fabric were studied.The optimum modification conditions were determined as follows： Glytac 40 g /L,sodium hydroxide 8 g /L,JFC 2 g /L,temperature 60 ℃,time 45 min and liquor ratio 1∶ 20.The results also indicated that Glytac modification could reduce the dosages of electrolyte salt and alkali during reactive dyeing of the fabric and dyeing temperature could be lowered,while utilization percentage of dye,fastness to washing and rubbing were enhanced without obvious influence on the light fastness.
