摘　　要：借助扫描电镜、红外光谱、X-射线衍射、热重分析、差示扫描量热分析等手段，研究了菠萝叶纤维的化学结构、结晶度和热惜能。结果表明：菠萝叶纤维表面有纵向裂缝和孔洞；红外结晶指数为0．923；其纤维素属于纤维素Ⅰ，纤维结晶度为76．63％，取向度为99．08％；最大热质量损失发生在300—400℃。The chemical structure, crystallinity and thermal property of pineapple leaf fiber are studied by means of SEM, IR, X - ray, TG and DSC in the paper. The result shows that pineapple leaf fiber surface has longitudinal cracks and holes. The degree of crystallinity of PALF is 0. 923 by infrared spectroscopy. The fiber is cellulose Ⅰ. The degree of crystallinity of PALF is 76. 63% and the degree of orientation of PALF is 99.08%. Its greatest weight loss appeares between at 300℃-400℃.
