Photo-induced surface grafting with glycidyl methacrylate (GMA) as monomer in
association with a pad-curing treatment by using a flame retardant (FR) solution
which contains 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP) and sulfamic
acid (H 2 NSO 3 H) has been used to improve the fire performance of PET fabric in
this study. The effects of initiator concentration, monomer concentration and the
irradiation time on the grafting percentage were investigated. The chemical structure
of grafted surface of the PET fabric was characterized by an attenuated total
reflection-infrared (ATR-IR) spectroscopy. The fire performance was evaluated by
the LOI and the vertical flammability tests, and the results indicate that the photo
grafting treatment could improve the flame retardancy and dripping resistance of PET
fabric. Thermal behaviour of treated PET fabric samples was investigated by
thermogravimetric (TG) and differential scanning calorimetric (DSC). The
morphology of the sample char residue was also investigated by scanning electron
microscope (SEM).
