In the paper the authors tried to use chemical disposal to bring the activity mass onto the surface of Kevlar fiber with the purpose of surface graft modification. In the paper the authors used the FTIR spectra to discuss the graft of toluene-2, 4-diisocyanate onto Kevlar fiber. The authors studied and analysed the effect of hydrolytic time on the content of -O-H group of the production, and the effect of hydrolyzation and hexyl-lactam steadily disposing on the graft reaction. The result showed that the content of -O-H group increased after hydrolyzation, it's helpful for the graft reaction, and hexyl-lactam steadily disposing made the graf product more stable. Through the research the authors came to the conclusion that by bringing some activity masses onto the fiber surface the authors can improve the interface of fiber/resin effectively.
在该论文中，作者试图采用化学处理方法将活性物质引入芳纶纤维表面，以进行表面接枝改性。作者在论文中利用傅里叶变换红外光谱（FTIR）探讨甲苯-2,4-二异氰酸酯在芳纶纤维上的接枝情况。作者研究并分析了水解时间对产物中-OH基团含量的影响，以及水解和己内酰胺稳定处理对接枝反应的影响。结果表明，水解后-OH基团含量增加，这有利于接枝反应，且己内酰胺稳定处理使接枝产物更稳定。通过该研究，作者得出结论：通过在纤维表面引入一些活性物质，可以有效改善纤维/树脂界面。
