摘　　要：羊毛纤维表面存在特殊的鳞片层结构,织物亲水性较差,易产生静电、起毛起球以及毡缩等问题,给织物的服用性能造成较大影响。文中采用聚乙二醇二丁二酸酯(PEGDSA)对羊毛进行改性,首先采用还原处理剂和过氧化氢处理羊毛织物,暴露更多的氨基,然后采用1-乙基-(3-二甲基氨基丙基)碳二亚胺盐酸盐(EDC)和N-羟基琥珀酰亚胺(NHS)交联剂方法将PEGDSA接枝到羊毛织物表面。结果表明:经过10%PEGDSA改性后羊毛织物具有良好的亲水性,织物毛效可以达到100 mm以上,毡缩率下降至10%以下;羊毛的抗起毛起球性能即使在2000次摩擦后仍然能够达到5级,同时织物强力保留率可达80%。There is a scale layer on the surface of wool fiber,which leads to poor hydrophilicity of the wool fabrics.The scale layer also makes wool prone to static electricity,pilling,felt shrinkage and other problems,which has a great impact on the wearing performance of wool fabric.In this paper,wool was grafted with polyethylene glycol disuccinate(PEGDSA).The wool fabric was first treated with LKZ-610 and hydrogen peroxide to expose more amino groups,and then the small molecule polymer PEGDSA was grafted onto the surface of the wool fabric by the EDC-NHS method.The results show that PEGDSA is successfully grafted onto the wool surface.After being grafted with 10%PEGDSA,the wool fabrics have good hydrophilicity,and the wicking height of wool fabrics can reach more than 100 mm,and the felting shrinkage of wool fabrics decreases rapidly to less than 10%.The anti-pilling properties of wool fabrics are also greatly improved to class 5 after 2000 times.Meanwhile,the strength retention rate of fabrics can reach 80%.
