Abstract

A process for improving the freeness of paper pulp, which comprises the steps of adding to the pulp at least 0.05 % , based on the dry weight of the pulp, of a cellulolytic enzyme, allowing the pulp to contact the cellulolytic enzyme for from about 40 minutes to about 60 minutes at a temperature of at least 40°C, adding at least 0.011% , based on the dry weight of the pulp, of a water soluble cationic polymer, adding at least 0.007% , based on the dry weight of the pulp, of a water soluble anionic or nonionic polymer and forming the thus treated pulp into paper.
