摘　　要：将PLA纤维完全溶解于NaOH溶液中,对溶液的紫外光谱进行了测试与分析。结果表明:PLA纤维溶液的紫外特征吸收波长是233nm,纤维浓度越大,溶液的吸光度值越高;测试温度越高,吸光度越大;PLA纤维溶液的紫外吸光度随纤维溶解温度的升高及NaOH浓度的增大而增大。The UV spectrum of the solution was tested and analyzed when the PLA fiber was dissolved in theNa OH solution absolutely. The result shows that 233 nm is the characteristic absorption wavelength of the PLA fiber solution. The greater the fiber concentration is, the higher the absorbance value of the solution is. The higher the temperature is, the greater the absorbance is. The UV absorbance of PLA fiber solution increases with the increase of the fiber solution temperature and the increase of NaOH concentration.
