Abstract Chemical disposal was used to bring the activity group onto the surface of Kevlar fiber for the purpose of surface grafting modification. The interfacial constitution of the grafting of toluene-2,4-diisocyanate (TDI) onto Kevlar fiber was determined by Fourier transform infrared spectroscopy. In the mean time, hexyl-lactam stabilization and poly-glycol (400, PEG) stabilization on the grafted product were also studied. The effects of different nTDI∶nPEG ratios on the production’s interfacial constitution was analysed. It is concluded that the stabilization took place on the surface. The intensity of the bands relented at about 3 300 cm-1 and was reinforced at about 1 700-1 720 cm-1 when the ratio of nTDI∶nPEG=1∶3, but when the ratio is 1∶1 and 1∶2, the bands at about 3 300 and 1 700-1 720 cm-1 are almost the same.
