This experiment aimed to graft PP nonwoven fabric with a silane coupling agent, then process it with chitosan or AgNO3, next to analyse and test it with related instruments, such as FT-IR, NMR, SEM, EDS, TGA etc., and finally study the influence of the modification of the silane coupling agent on the properties of the processed fabric. The results indicated that the silane-coupling agent could be effectively grafted onto the surface of the PP nonwoven fabric. On the other hand, the thermal stability of the PP non-woven fabric changed due to the processing of the silane-coupling agent and chitosan or AgNO3. In addition, the PP nonwoven fabric attained good antibacterial and water imbibitious properties through post-processing the nonwoven fabric with polyacrylic acid sodium (PAANa) and chitosan or AgNO3.

Celem badań było szczepienie włóknin polipropylenowych silanami ułatwiającymi adhezję, traktowanie ich chitozanem lub AgNO3 a następnie analiza otrzymanych próbek między innymi za pomocą FT-IR, NMR, SEM, EDS i TGA. Wyniki analiz pozwoliły na określenie wpływu modyfikacji włóknin za pomocą silanów. Stwierdzono, ze silanami można efektywnie szczepić obydwie powierzchnie włókniny. Z drugiej strony stabilność termiczna włóknin polipropylenowych zmieniała się w wyniku oddziaływania silanu, chitozanu i AgNO3. Nadto stwierdzono, ze włókniny polipropylenowe zyskują właściwości antybakteryjne oraz zwiększają nasiąkliwość w wyniku potraktowania włókien po procesie napawania kwasem poliakrylowym (PAANa) i chitozanem lub AgNO3.
