Abstract
Tissue and paper manufacturing companies have common problems with increasing cost of imported virgin pulp and the restriction of using woods in the forest. Possibility of using bagasse pulp for solving those problems was studied. In order to reduce the production cost and study the dependency on pulps, bagasse pulp has been studied for mixing with Sw-BKP and Hw-BKP. Optimum blending ratio of wood pulps and bagasse pulp to enhance tissue properties were analyzed. Various properties of the hand sheet after blending of wood pulp and bagasse pulp were measured. As results, the bagasse pulp could substitute the hard wood pulp with similar properties of tissue. Therefore, we judged that the bagasse pulp was suitable for replacement of the hardwood pulp.
