Abstract [en]

In this work we have investigated the potention to maximize wet strength of papers made from lignin rich pulps by combining wet strength chemicals in with hotpressing. We have earlier shown that it is possible to increase density, dry and wet-strength of lignin rich paper sheets by hotpressing utilizing the softening properties of lignin. This work indi-cated that it was possible to achieve synergistic effects when using wet strength agents.
