PET flame-retardant fabric with the presence of sensitizer trimethylolpropane triacrylate has been prepared by supercritical CO2 progressing method and then irradiated by electron irradiation. Irradiation changed the burning behavior of the PET flame-retardant fabric which had no dripping but burned up with the flaming and char forming. In order to explain the irradiation effect, XPS is used to investigate the change of the chemical bonds. The XPS data analysis indicated that during irradiation, the effective flame-retarded group C–O–P was broken, so its flame retardance disappeared at time of combustion, while there was no melt drip because the crosslinking was introduced by irradiation.
