Both bamboo pulp fiber and bamboo fiber cellulosec fibers.In order to compare their difference in performance,this paper has studied the two fibers from longitudinal and cross section morphological structure,anti-ultraviolet capability,resistance to inorganic and organic chemical treatment,and the dying test with tinctorial substance.The results show that their morphological structures are different.They both are resolvable in inorganic acids,but are not resolved in organic solvents.The alkali resistance of bamboo pulp fiber is superior to that of bamboo fiber,and the colorability and the performance of anti-ultraviolet of bamboo fiber are evidently better than those of bamboo pulp fiber.
