摘　　要：采用自制改性剂对棉织物进行退煮漂和改性一浴加工,分析了氢氧化钠用量、硅酸钠用量、双氧水用量、温度、时间和改性剂用量对棉织物染色效果的影响。结果表明,优化的棉织物退煮漂和改性一浴工艺为:氢氧化钠20 g/L,硅酸钠3 g/L,30%双氧水24 mL/L,改性剂20 g/L,温度80℃,时间70 min。棉织物经退煮漂和改性一浴处理后,可实现活性染料无盐染色,其耐水洗色牢度及干摩擦色牢度优异,但湿摩擦色牢度有待进一步改进。Desizing-scouring-bleaching and modification of cotton fabrics in one bath is carried out. Factors exerting influence on dyeing results are discussed, such as dosages of NaOH, Na2SiO3 , H202 and the modifier, treatment temperature and time. It is found that the optimized one bath process of desizing-scouring-bleaching and modification is defined： NaOH 20 g/L, Na2SiO3 3 g/L, H202（30%） 24 mL/L, the modifier 20 g/L, and treating at 80 ℃ for 70 min. Salt free reactive dyeing of cotton fabric can be realized, and the dyeings have good color fastness to washing and dry rubbing, but the wet rubbing fastness need to be improved.
