纳米催化剂在毛织物防皱整理中的应用

Nano-materials as the catalyzator applications in the crease-resistant finish of wool fabric

纳米材料是一种新型功能材料,具有表面积大,表面活性中心多,吸附性强等一般材料所不能比拟的优异性能,易引发交联反应,且对环境无污染。用纳米氧化硅作催化剂,对经剥鳞处理的毛织物进行马来酸酐的抗皱整理,通过实验分别测定不同浓度和不同焙烘温度的整理效果,确定最佳纳米氧化硅的浓度和最佳焙烘温度,整理后织物的干湿折皱回复角有明显提高,且断裂强度保持率也较高,手感较好。

The wool fabrics were treated with chlorine for stripping scale and the finished with maleic anhydride as crease-resistant agent and nano-silica as catalyzator for crease resistance.The effect of the concentration of nano-silica and heating temperature,the optimum process conditions were obtained,As the result,the finished fabrics,featured better dry-wet elastic recovery,satisfactory mechanical property and style.
