Abstract:

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 showed that after the functional treatment, the PP fabric showed good metallophilicity. In addition, the hygroscopicity and dyeability are improved to some extent.

Key words: low-temperature plasma, polypropylene nonwoven fabric, aziridine bridging ahent, chelator, metallophilicity
