Our analysis data showed that the procedure of extracting bamboo fibers from bamboo did not change the crystalline feature( cellulose) of bamboo fibers,but their degree of crystallization from WAXD and crystallinity index from FT-IRwere higher than those of cotton.Thermal stability property and decomposition mechanism of natural bamboo fibers were the same as those of cotton,whereas they exhibitedslightly lower heat-absorption and heat-release than cotton when decomposed under nitrogen and air respectively due to the stronger hydrogen bonding interaction between their molecular chains.
