Title (EN) PAPER MAKING PROCESSES USING ENZYME AND POLYMER COMBINATIONS
(FR) PROCEDES DE FABRICATION DE PAPIER UTILISANT DES COMBINAISONS D'ENZYME ET DE POLYMERE
Abstract:
(EN) Methods of making paper or paperboard are described. In one method, at least one cellulytic enzyme composition and at least one cationic polymer composition are introduced to a paper making pulp at about the same time to form a treated pulp. The pulp may also be treated with at least one cationic starch. The resulting pulp is formed into a sheet of pulp. Other paper making processes are also described. A paper making apparatus is also described for carrying out the methods. Paper and paperboard made according to the methods are also described.
(FR) L'invention concerne des procédés de fabrication de papier ou de carton. Dans un procédé, au moins une composition d'enzyme cellulytique et au moins une composition de polymère cationique sont introduits dans une pulpe de papier à peu près simultanément pour former une pulpe traitée. La pulpe peut aussi être traitée à l'aide d'au moins un amidon cationique. La pulpe résultante peut être façonnée en une feuille de pulpe. D'autres procédés de fabrication de papier sont également décrits. Un dispositif de fabrication de papier également décrit permet de mettre en oeuvre les procédés. L'invention concerne aussi le papier et le carton fabriqués selon les procédés.
