Properties and application of wet rubbing fastness improver assisted by copper particles

为提高活性染料深色织物湿摩擦牢度,在丙烯酸丁酯、甲基丙烯酸甲酯及十二烷基苯磺酸钠水溶液混合体系中制备了铜颗粒增效湿摩擦牢度提升剂。使用扫描电子显微镜对其形貌进行表征,测试其粒径,研究了其作为湿摩擦牢度提升剂对活性染料染色棉织物的最佳整理工艺及应用性能。结果表明：铜颗粒增效湿摩擦牢度提升剂的平均粒径为2 472 nm,改性铜微粒在水溶液中呈石榴状聚集。浸轧法的最佳整理工艺为：湿摩擦牢度提升剂质量浓度20 g/L,p H值5-6,焙烘温度110-120℃,焙烘时间2 min。当活性染料用量分别为6%、8%（o.w.f）时,经铜颗粒增效湿摩擦牢度提升剂整理后活性染料染色棉织物的耐摩擦色牢度提高1-1.5级。

In order to improve the wet rubbing fastness of fabrics in dark shade,the wet rubbing fastness improver assisted by copper particles was synthesized from butyl acrylate,methyl methacrylate and sodium dodecyl benzene sulfonate.Morphology and dispersion distribution of the wet rubbing fastness improver assisted by copper particles was analyzed by scanning electron microscopy and particle size analysis.It was found that the modified copper particles were assembled like a pomegranate in water.Mean particle diameter of the wet rubbing fastness improver assisted by copper particles is around2 472 nm.Thus,the finishing processes and application of the wet rubbing fastness improver on cotton fabrics dyed with reactive dyes were investigated.It was found that the optimal finishing process was：the wet rubbing fastness improver mass concentration 20 g / L,p H value 5-6,baking temperature 110-120 ℃,baking time 2 min,and padding method.The wet rubbing fastness of cotton fabrics dyed with reactive dyes increased by 1-1.5 grades after treatment with wet rubbing fastness improver,when reactive dyes concentration was at 6% and 8%（o.w.f）,respectively.
