摘要

This experiment aimed to graft PP non-woven fabric with a silane coupling agent, then process it with chitosan orAgNO3, 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 non-woven 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 orAgNO3. In addition, the PP non-woven fabric attained good antibacterial and water imbibitious properties through post-processing the non-woven fabric with polyacrylic acid sodium (PAANa) and chitosan orAgNO3.
