Bulky paper from chemically crosslinked hardwood kraft pulp fibers

Research output: Contribution to journalArticleScientificpeer-review


Chemical crosslinking of hardwood kraft pulp fibres stabilize physical shape and structure of the fibres by forming water resistant covalent chemical bonds between cellulose molecules. In paper and board making chemically crosslinked fibers are less prone to swelling and deformation. Blocking of fibers surface hydroxyl groups by reactions with crosslinking agents reduce fibres ability to form inter-fibre hydrogen bonds. Those parallel effects result in higher bulk, increased light scattering and faster drying of the formed paper. Use of chemically crosslinked pulp offers an attractive option for paper and board makers to produce high bulky papers and boards.
