| Abstract | Three fast growing hardwood Kraft pulps (Eucalyptus camaidaiensis of Thai origin, Eucalyptus grandis and dannis of Latin America origin and Acacia mangium of indonesian origin) were compared in fiber chemistry, fiber morphology, physical properties of 100 % pulp sheet and physical properties of furnish sheet. Study showed that Latin Eaca contained higher pentosan and fiber charge than Acacia and Thai euca. Acacia and Thai Eaca were found to be morphologically similar as well as in chemistry, while Latin Euca was longer and wider. Sheet physical properties made of 100 % pulp under varying refining level clearly showed that Acacia and Thai Euca gave apparently better Opacity and light scattering coefficient, but poorer strength (tensile, tear, Scott bond) than Latin Erica. With regard to bulk and air permeability, Latin Euca was the lowest. Acacia gave lower PPS roughness than Thai Euca. Three fast growing hardwood Kraft pulps were refined and applied in uncoated base paper. In this case, No significant differences in roughness were found; Acacia still showed advantage in opacity, light scattering and bulkiness, Thai euca was in between; Latin Erica was the poorest in these respects- However= advantage of Latin euca in strength was demonstrated when being applied in uncoated base paper. |
