Effects of Cellulase Treatment on Structures of Bamboo Fiber

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 erosion and cracks increased,but the thermal stability unchanged.
