利用扫描电镜、X射线衍射等测试方法对菠萝叶纤维、亚麻纤维、苎麻纤维和棉花纤维的微观形态结构进行了分析。分析认为：菠萝叶纤维的形态结构有区别于其它三种植物纤维，有较大的比表面积；菠萝叶纤维的结晶度与亚麻纤维和苎麻纤维接近，高于棉花纤维。在热带标准状态下，采用烘箱干燥法和回归模型分析法，对测试的四种进行了吸湿、放湿测试与分析。结果表明：在吸湿性能方面，菠萝叶纤维表现最佳，棉花纤维最差；在纤维吸湿平衡回潮率和吸湿速率方面，菠萝叶纤维与亚麻纤维和苎麻纤维相近，且高于棉花纤维；在纤维放湿平衡回潮率和放湿速率方面，菠萝叶纤维高于亚麻纤维、苎麻纤维和棉花纤维。

The article adopts several test methods to analyze the micro morphology of pineapple leaf fiber ,flax fiber , ramie fiber and cotton fiber ,including scanning electron microscopy (SEM ) ,X-ray diffraction (XRD) and others . The Test results show that pineapple leaf fiber's morphological structure is different from the other three's because of its larger specific surface area .Pineapple fiber's crystallinity is close to flax fiber and ramie fiber's but higher than that of cotton fiber .Under the standard tropical condition ,oven-drying method and regression model are used to test and analyze the four fibers'moisture absorption and liberation performances .Test results show that pineapple fiber's moisture absorption performance is the best and cotton fiber's is the worst .Pineapple fiber's moisture regain rate after moisture sorption equilibrium and moisture absorption rate are close to those of flax and ramie fibers and are higher than cotton fiber ;its moisture regain rate after moisture liberation equilibrium and moisture liberation rate are higher than those of flax ,ramie ,and cotton fibers .
