| 摘 要： | 研究了大麻纤维高温脱胶技术,讨论了脱胶温度和碱量对大麻纤维成分与结构的影响。用SEM、FT-IR、XRD对大麻纤维高温脱胶前后的表面形态结构、聚集态结构进行了表征。实验结果表明:高温脱胶后大麻纤维中的半纤维素和木质素含量分别下降了79.1%和83.5%,纤维素含量提高;大麻纤维的结晶度上升,其结晶度与NaOH的质量分数及反应温度有关。

| Abstract: | The technique of high temperature degumming of hemp was researched,and the effect of temperature and concentration of alkali on the composition and structure of hemp was discussed.Scanning electron microscope(SEM),Fourier-Transform-Infrared(FT-IR) and wide angle X-ray scattering(WAXS) were used to characterize the morphology and structure of aggregating state of hemp before and after high temperature degumming.The experiment results demonstrated that after high temperature degumming the contents of hemicellulose and lignin of the hemp have reduced by 79.1% and 83.5% respectively.The crystallinity of treated hemp is raised,which is related to the treatment temperature and concentration of alkali. |
