Title: (EN) PAPER MAKING PROCESSES USING ENZYME AND POLYMER COMBINATIONS
(ES) PROCESOS PARA FABRICAR PAPEL USANDO COMBINACIONES DE ENZIMAS Y POLIMEROS
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.
(ES) La presente invención se refiere a métodos de fabricación de papel o cartón. En un método, por lo menos una composición de enzima celulítica y por lo menos una composición polimérica catiónica son introducidas a la pulpa para la fabricación de papel al mismo tiempo para formar una pulpa tratada. La pulpa puede también ser tratada con por lo menos un almidón catiónico. La pulpa resultante es formada a una hoja de pulpa. Otros procesos de fabricación de papel son también descritos. También se describe un aparato de fabricación de papel para llevar a cabo los métodos. También se describen papel y cartón fabricados de acuerdo con los métodos.
