Improvement of Flame Retardancy of PET Fabric via UV Induced Grafting of Organic Phosphorus Monomer
Source abstract
Abstract
Poly(ethylene terephthalate) (PET) fabric was modified with bis[2-(methacryloyloxy)-ethyl] phosphate using 2,4,6-trimethylbenzoyldiphenyl phosphine oxide as photoinitiator via UV induced grafting to improve flame retardant performance. Effects of monomer concentration, initiator amount, grafting time and ethanol-water volume ratio on grafting yield were investigated. The chemical structure of grafted PET fabric was characterized by FTIR and SEM observation. Thermal behaviour of grafted PET fabric was investigated by thermal gravimetry analysis. The results indicated that the residual char of grafted samples reached 13.6% at 800oC, which was higher than that of untreated fabric. The flame retardant bis[2-(methacryloyloxy)-ethyl] phosphate promoted formation of residual char, which improved the anti-dripping property and flame retardancy of PET fabric.
