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.
