The surface properties of unbleached softwood (Pinus sylvestris) and hardwood (Betula verrucosa) kraft pulps were modified by treating the fibre surfaces with specific xylanase and mannanase (Trichoderma reesei). The amounts and accessibilities of surface carboxyl groups in untreated and enzyme-treated fibres were analyzed using adsorption of cationic ...

Recycling performance of softwood and hardwood unbleached kraft pulps for packaging papers
TAPPI Journal, 2023The scope of this work is to evaluate the recyclability potential of hardwood and softwood unbleached kraft pulps, leading to a sound basis for comparison and even to support a decision about fibers according to the performance achieved. The influence of successive recycling cycles (up to 10 cycles) on the fiber morphology, pulp suspension drainability,

Characterisation of fines from unbleached kraft pulps and their impact on sheet properties
hfsg, 2008Abstract Fines are an essential component in the papermaking process because they have a profound influence on the behaviour of the wet web and on the mechanical properties of the final sheet. Primary fines are present in the pulp prior to refining, and secondary fines are produced during refining.

Effect of Xylanase and Dosage on the Refining Properties of Unbleached Softwood Kraft Pulp
Journal of Wood Chemistry and Technology, 1999Two xylanase preparations were compared at different doses for their abilities to enhance the refining properties of a never-dried, unbleached kraft pulp derived from radiata pine. These enzymes varied in their ability to solubilise xylan from pulp, and the selective removal of pulp xylan did not reduce intrinsic fibre strength.
