Abstract:

In order to improve interfacial adhesive property and prolong service life of polyester fabric/polyvinyl chloride composites, the polyester fabric were subjected to surface modification with homemade fiber surface modifier by deoiling treatment, alkali treatment and modifier coating. The polyester fabric/polyvinyl chloride composites were prepared by using the treated polyester fabrics as reinforcer and polyvinyl chloride as matrix. The surface morphology, surface energy and monlfilament strength of polyester fiers before and after modification as well as the mechanical properties interfacial peeling properties of polyester fabric/ polyvinyl chloride composites were tested by scanning electron microscope, atomic force microscope, dynamic contact angle testing and tensile testing, respectively. The  results show that the roughness of the modified polyester fibers is obviously improved, the surface energy increases by 79.77% compared with untreated polyester fibers, resulting in a 94.82% incerase in the interfacial peeling strength of polyester fabric/polyvinyl chloride composites.
