Abstract

About 80% of pulp is imported from abroad which is used in most of paper mills in Korea. In order to reduce production cost, abundant non-woody pulps attracts interest to papermaker when it has high quality with low price. Bagasse pulp has high brightness with low price among non-woody pulps. Bagasse pulp is widely used to produce newsprint, printing paper, and paperboard in subtropic and tropical countries. Bagasse pulp has short fiber length, thick fiber width, and high fines content. In order to replace hardwood bleached kraft pulp (Hw-BKP) efficiently, handsheet’s physical properties depending on bagasse pulp mixing ratios were analyzed. When the bagasse pulp mixing ratio was increased, breaking length, stretch, folding endurance, tear strength, and stiffness of handsheets were decreased. Therefore the mixing ratio of the bagasse pulp up to 10-15% was considered proper to replace Hw-BKP.
