| Abstract | Bamboo is fast growing and has long, thin fibers and therefore has potential as a raw material for pulping and papermaking, especially in those wood deficient regions, bamboo also can replace some part softwood in paper furnish. Usually, bamboo pulping is kraft process. The research study concerned on the effect of alkali charge and sulfidity on the kappa number, yield, viscosity and brightness in the case of Vietnamese bamboo kraft pulping. Besides that, the effects of cooking parameters on oxygen delignification and bleaching were studied also in this research. Higher alkali charge can get lower yield, higher residual alkali, lower kappa number, lower viscosity and higher brightness. Higher sulfidity can obtain higher yield, lower residual alkali, lower kappa number, higher viscosity and higher brightness. In 02-delignification and bleaching, pulp of higher kappa number consumes more chemicals to get lower kappa number. It is more difficult to remove residual lignin from pulp of higher kappa number in cooking. |
