Abstract：The mechanism of the modification of Kevlar fiber by polypropylene glycol(PPG) and cis-2-butene-1, 4-diol was studied in the paper, the authors learned the esterification of toluene-2, 4-diisocyanate (TDI) onto Kevlar fiber by infrared spectrum. In the mean time, the infrared spectrograms of the productions which steadily disposed by PPG and butendiol were analysed respectively, the result showed that the intensity of the bands was reinforced at about 1 700-1 720 cm-1 after the samples were steadily disposed, that is to say, the group of —NCO has been stabilized into —NHCO group, the effect of steady disposal was obvious; but the disposal effect of butendiol was apparently better than PPG’s at the same condition. Finally, the authors compared the influence of different mol rates between TDI and butendiol on the productions. Based on the consequence, excessive butendiol would prevent the Kevlar fiber from farther reaction, therefore, the mol rate between TDI and butendiol should approach 1∶1.
