Abstract
Bamboo is treated by solution of sodium hydroxide to extract bamboo fiber. The alkaline treatment of bamboo is performed at several conditions, which are the concentration of sodium hydroxide solution, 0.5 to 2.0% and treatment time, 10 to 150 minutes. The diameters of bamboo fiber obtained by alkaline treatment are 0.2 to 0.8mm. The required treatment time to obtain bamboo fiber decreases with increasing concentration of sodium hydroxide solution. Tensile test is conducted to investigate the tensile properties of bamboo fiber. The tensile strength of bamboo fiber after the treatment can be obtained as before the treatment.
