METHOD FOR REFINING, IN AN ENZYMATIC MEDIUM, PAPER PULP COMPRISING CELLULOSE FIBERS IN ORDER TO REDUCE THE LENGTH OF SAID FIBERS

摘要

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.
