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).
