摘　　要：采用阳离子改性剂色媒体对棉织物进行改性处理,之后用酸性染料染色。探讨并分析了改性剂色媒体用量、染色温度、染色时间、染色浴比等工艺参数对染色效果的影响,优化改性棉织物酸性染料浸染染色工艺,并介绍了改性棉织物染色后的固色处理工艺。结果表明,当染料用量为1.0%时,优化的工艺条件为:改性剂色媒体用量为3.0%,染色温度70℃,染色时间40 min,浴比1∶30;改性棉织物染色后具有较好的耐摩擦色牢度和沾色牢度,但耐皂洗褪色牢度较差,应加以进一步的固色处理,高分子固色剂DM的最佳用量为2.0%。Cotton fabric was modified by cationic modifier color media and dyed by acid dyes. The effects of the dosage of modifier color media, dyeing temperature, dyeing time and bath ratio on dyeing effect were discussed and analyzed, dip dyeing process of modified cotton fabric with acid dyes was optimized, and the fixation process of modified cotton fabric was introduced. The results show that when the dosage of acid dyes is 1.0%, the optimal process conditions are that the dosage of color media is 3.0%, dyeing temperature is 70 ℃, dyeing time is 40 minutes, bath ratio is 1：30; modified cotton fabric has good fastness to rubbing and staining, but the fastness to soaping is poor; it should be treated by further fixation, and the suitable dosage of macromolecule fixing agent DM is 2.0%.
