<p>A process of delignifying and bleaching a chemical wood pulp with hydrogen peroxide and dicyandiamide as an ativator provides a higher degree of delignification and brightness of the pulp and overcomes problems of fibre degradation. The process comprises adding hydrogen peroxide and dicyandiamide as a bleaching activator to a chemical wood pulp slurry under alkaline conditions.</p> |
