菠萝叶纤维的脱胶工艺及其结构与性能研究

Degumming process, structure and properties of pineapple leaf fiber

使用SEM、FT-IR、TG、DTG、DSC与力学性能统计法对菠萝叶纤维的脱胶工艺进行研究,分析脱胶工艺对菠萝叶纤维结构与性能的影响,并且对酶法脱胶工艺与化学脱胶工艺进行对比。结果表明:与化学脱胶工艺相比,酶法脱胶工艺的菠萝叶纤维杂质更复杂,分裂度与线密度更大,热稳定性更高。

The degummi ng process of pin eapple leaf fiber was an alyzed by SEM, FT-IR, TG, DTG, DSC and mechanical properties statistical method. And the effect of degumming process on the structure and prop erties of pin eapple leaf fiber was analyzed. The enzymatic degummi ng process and chemical degumming pro cess were compared. The results showed that compared with chemical degumming process, the impurities of pin eapple leaf fiber treated by enzymatic degummi ng process was more complicated, the cracking strength and linear density were higher, and the thermal stability was better.
