摘　　要：利用化学预处理结合纤维素酶的作用对竹原纤维进行改性,借助于扫描电镜、傅立叶红外吸收光谱、X-射线衍射等实验技术,研究处理前后竹原纤维的形态和内部结构变化。研究结果表明:酶处理切断并还原纤维素分子链为葡萄糖,同时也降解了部分半纤维素,使竹原纤维的结晶度降低;酶处理后的竹原纤维横截面微孔变大,纵面出现明显的侵蚀,裂纹有所增加;热稳定性基本不变。Implementing chemistry pretreatment and cellulase treatment on bamboo fiber for modification,the morphology and internal structure changes of treated bamboo fibers were studied by SEM,FTIR,WAXS and other experimental techniques.The results showed:cellulase treatment cut off and restored the cellulose molecular chain to glucose and also decompose some hemi-cellulose which lead to lower crystallinity;the cross-section micro-porous of treated bamboo fiber became larger longitudinal-section appeared obvious ero...
