Our previous study shows that surface photografting modi fi cation with maleic anhydride followed by
reacting  with  triethanolamine  can  improve  the fl ame  retardancy  of  nylon-6,6  fabric.  In  this  study,
acrylamide was used as a grafting monomer to improve the fl ame retardancy of nylon-6,6 fabric. The
effects of monomer concentration and irradiation time on photografting were investigated. The surface
structure of the sample was analyzed by attenuated total re fl ection infrared spectroscopy (ATR-FTIR).
Flame retardancy was characterized by limiting oxygen index test (LOI), the vertical burning test and
cone calorimeter. The grafted sample has a higher LOI value than the untreated sample, and has no
melting  drip  during  the  vertical  burning  test.  The  improvement  of  the fl ame  retardancy  and  char
formation of the nylon-6,6 fabric have also been veri fi ed by the thermogravimetric analysis (TGA) and
scanning electron microscopy (SEM) analysis.
