Abstract
Xylan extracts from southern US hardwood were used for the adsorption of both hardwood and softwood pulp. Pulp beatability and physical strength properties were determined and compared with those of the conventional Kraft pulp and pre-extracted modified Kraft pulp. The results indicated that hemicelluloses adsorption greatly improved pulp beatability. Compared to conventional Kraft pulp, a significant increase in pulp physical strength could be achieved by adsorbing hemicelluloses onto pulp. An increase of up to 20-25% in tensile strength was observed for both hardwood and softwood pulps, as well as an 8-10% increase in tear strength, achieved for comparing pulp tear strength at a certain tensile level. In addition, softwood adsorbed pulp showed a slightly higher bulk property at the same strength level.
