Enzymatic beating of unbleached softwood kraft pulp is investigated in this paper.At the same time, the optimum conditions for enzymatic beating are found out. Moreover, the power consumption of enzymatic beating is discussed under the optimum conditions. The results show that the optimum conditions for enzymatic beating are as follows： temperature 40 ℃, enzyme dosage 1. 000 g/t, pH 6, time 60 rain. Under the optimum conditions, the power consumption of enzymatic beating would drop by 33% and the pulp property could be improved. Studies are also conducted with electron microscope scanning, the resuits show that not only the fiber surface has more denudation, and fibrillating is improved, but also pulp fiber has less cutting.
