摘　　要：涤棉混纺织物采用常规工艺进行染色能够获得较好的色牢度,但是染色时间长而且污水处理成本高,不符合低碳环保的要求。采用分散/活性染料一浴一步法染色改进工艺替代常规工艺。在常温(40℃)状态下,以元明粉150 g/L,促染剂1 g/L,2℃/min升温至80℃并保温1 min,以1℃/min升温至95℃并保温1 min,以1℃/min升温至127℃并保温30 min进行分散染料与活性染料染色。实验结果表明,染色织物耐干摩擦色牢度可达4~5级,耐湿摩擦色牢度可达3~4级,耐皂洗色牢度可达4~5级,耐汗渍色牢度达到4~5级,同时能够缩短染色时间、节约用电、减少污水排放,对降低生产成本起到了积极作用,满足了实际生产需求。The polyester cotton blended fabrics could be dyed by conventional process to obtain good col-or fastness of the fabric,but the dyeing time was long and the sewage treatment cost was high,which did not meet the requirements of low carbon environmental protection.One bath one step dyeing process with disperse/reactive dyes was adopted instead of conventional process.At room temperature(40℃),with 150 g/L powder,1 g/L dye promoter,2℃/min heating to 80℃and holding for 1 min,1℃/min heating to 95℃and holding for 1 min,disperse dyes and reactive dyes were dyed with 1℃/min heating to 127℃and kept warm for 30 min.The results of the experiments showed that the color fastness of dyed fabric to dry friction could reach 4-5 level,the color fastness to wet friction could reach 3-4 level,the color fastness to soap could reach 4-5 level,and the color fastness to perspiration could reach 4-5 level.At the same time,it could shorten the dyeing time,save electricity and reduce sewage discharge,which played a positive role in reduc-ing the production cost and met the needs of actual production.
