摘　　要：利用等离子体对惰性丙纶非织造布进行修饰处理,在织物表面引入羧基和羟基极性反应位点。通过接触角测试和显微镜观察确认了改性织物的亲水性和形貌,然后将自制的羧甲基壳聚糖与乙二胺四乙酸在使用缩合剂N,N-二环已基碳酰亚胺的条件下接枝处理织物。研究了等离子体处理时间、吸附时间对铜离子吸附性能的影响。结果表明,低温等离子处理后,织物的亲水性得到了明显改善,织物的接枝率随等离子体处理时间的延长而增大,铜离子吸附能力与吸附时间呈正相关关系。Plasma is used to modify the inert polypropylene nonwoven fabric,and carboxyl and hydroxyl polar reaction sites are introduced on the surface of the fabric.The contact angle test and microscope observation confirm the hydrophilicity and morphology of the modified fabric.Then,the homemade carboxymethyl chitosan and ethylcnediaminetetraacetic acid are grafted on the fabric under the condition of using a condensing agent N,N-dicyclohcxylcarboximide.The effects of plasma treatment time and adsorption time on the adsorption performance of copper ions are studied.The results show that hydrophilcity of the fabric improves largely after plasma treatment,the grafting rate of the fabric increases with the increase of plasma treatment time,and the copper ion adsorption capacity is positively correlated with the adsoiption time.
