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　3300　cm-1　and　was　reinforced　at　about　1700-1720　cm-1　when　the　ratio　of　nTDI:nPEG　=　1:3,　but　when　the　ratio　is　1:1　and　1-2,　the　bands　at　about　3300　and　1700-1720　cm-1　are　almost　the　same.
