反应性阳离子改性剂的改性工艺探讨

合成的反应性阳离子改性剂用于对棉织物进行改性处理,并通过正交实验法优化改性工艺条件。实验结果表明,改性的最佳工艺条件为:改性剂用量4%、pH值为9、温度70℃、处理时间40 min。织物改性后染色的K/S值有较大幅度的提高,染色牢度较好。实验中结合X型活性染料低温染色工艺,探讨了棉织物清洁染色的可行性。

The discussion of modification process for reactive cationic modifier

The bifunctional reactive cationic modifier was synthesized, which was used to cotton fabric＇s modification. Orthogonal experiment was used to determine the optimal process conditions. The results showed that the K/S values of reactive dyed fabric were improved under the condition of modifier at 4% （ o. w. f）, pH = 9, and processing at 70℃for 40 minutes. The clean dyeing methods for cotton fabrics were researched combining with low temperature dyeing of X type reactive dyes in the experiment.
