聚丙烯非织造布的亲金属离子功能化改性

为得到具有亲金属离子性聚丙烯（PP）非织造布，利用低温等离子体联合技术对PP非织造布进行改性。首先采用氧气低温等离子体预处理PP非织造布，使其表面引入反应活性官能团。然后通过架桥三羟甲基丙烷三3-(2-甲基氮丙啶基)丙酸酯]（TTMAP）使螯合剂在预处理PP非织造布表面发生交联固定反应，利用傅里叶变换红外光谱法与X射线电子能谱分析证实了功能化前后PP非织造布表面的化学成分变化。结果表明：经功能化处理的PP纤维具备了良好的亲金属离子性，同时其吸湿及染色性能也得以改善。

Metallophilicity modification of polypropylene nonwoven fabric

A low-temperature plasma composite technique is used to perform metallophilic modification on polypropylene (PP) fabric. Firstly, the oxygen plasma is used for the pretreatment of PP fabric to produce reactive functional groups, then, the produced reactive functional groups on the PP surface are used to graft chelators in the presence of trimethylolpropane tris 3- (2-methyl aziridinyl) propionate (TTMAP) bridging agent. The chemical constituent change is confirmed by the analysis of FT-IR and XPS. The results showedthat after the functional treatment, thePP fabric showed good metallophilicity. In addition, the hygroscopicity and dyeability are improvedto some extent.
