Abstract:

Polyethylene terephthalate（PET）fabric was functional finished with graphene oxide (GO) and coupling agent KH560 by conventional pad-dry-cure method. The influence of functional finish on anti-dripping property and structure of the fabric was investigated. The results showed that PET fabric had no dripping with the good char forming at time of combustion. SEM result show that the graphene oxide film is formed uniformly on the surface of PET fabric and the residue char after burning had the intrinsic structure of PET fabric with the dense and tight sate. The thermal property changed a little, and XPS data analysis show that the ratio of C/O decreased and the function group C=O increased in the char after vertical burning test. Hence, the addition of GO play the physical role on the dripping resistance of coated PET fabrics apparently.
