摘要: A process for improving freeness of paper pulp which comprises these steps: a) Adding to the at least 0.05% based on dry weight pulp, a cellulolytic enzyme; b) Allowing contact enzyme 20 minutes temperature 20° C.; c) 0.0007% water soluble cationic polymer, and then d) Forming thus treated into paper.
