Title (EN) METHOD FOR REFINING, IN AN ENZYMATIC MEDIUM, PAPER PULP COMPRISING CELLULOSE FIBERS IN ORDER TO REDUCE THE LENGTH OF SAID FIBERS
(FR) PROCÉDÉ DE RAFFINAGE EN MILIEU ENZYMATIQUE D'UNE PÂTE PAPETIÈRE COMPORTANT DES FIBRES CELLULOSIQUES AFIN DE RÉDUIRE LEUR LONGEUR
Abstract: front page image
(EN)The invention relates to a method for refining, in an enzymatic medium, paper pulp comprising cellulose fibers from sources other than wood or from recycled material, wherein said pulp comprises more than 10% of fibers having a length greater than around 2 mm, the method being characterized in that it includes the steps of: refining the paper pulp, an enzymatic solution being mixed into the pulp before and/or during the refinement so as to increase and accelerate, during the refinement, the effect of cutting the cellulose fibers, in particular those having a greater length; inhibiting the enzymatic action in the paper pulp at the end of or after the refinement; and recovering the refined paper pulp.
(FR)Procédé de raffinage en milieu enzymatique d'une pâte papetière comportant des fibres cellulosiques issues de sources autres que le bois ou de matière recyclée, cette pâte comportant plus de 10% de fibres ayant une longueur supérieure à 2mm environ, caractérisé en ce qu'il comprend les étapes de : - raffinage de la pâte papetière, une solution enzymatique étant mélangée à la pâte avant le raffinage et/ou pendant le raffinage, de façon à accentuer et accélérer lors du raffinage l'effet de coupe des fibres cellulosiques, en particulier celles de plus grande longueur; - inhibition de l'action enzymatique dans la pâte papetière en fin de raffinage ou après le raffinage; et - récupération de la pâte papetière raffinée.
