Effects of Thermal Treatment on Chemical Transformation of Short Bamboo-Fibers

Abstract

This study was performed to investigate the influence of the thermal treatment on the chemical transformation of short bamboo-fibers. Results showed that cleavage of acetyl groups of the hemicellulose occurred at elevated temperature and completed beyond 190 ºC for more than 3 h, resulting a noticeable increase of cellulose content at up to 190-205 ºC during 3 h and a significant mass loss at elevated temperature beyond 205 ºC for 3 h. The possible effects of chemical changes on the reduction of hygroscopicity have been discussed.
