Abstract

Mill birch kraft pulp was fractionated using hydrocyclones and a pressure screen equipped with smooth-hole screen basket. Through hydrocyclone fractionation a coarse fraction was obtained having a high tensile stiffness and no extractives. The fine fraction had a high bonding ability and a high xylan and extractives content. The coarse fraction could be used in the top layer of board or in fine paper. The fine fraction obtained by hydrocyclone and pressure screen fractionation could be used for bonding in board middle layer or as a source of xylan. The tensile stiffness and Scott bond of the fractions could be improved further by optimized refining, using lower specific edge load and higher refining consistency.
