Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mechanical pulping method to enhance the efficiency of mechanical refining process and develop the quality of pulp. SOLUTION: A mechanical pulping method comprises:defibrating a comminuted cellulosic material in a pre-treatment step;mechanically refining the defibrated cellulosic material in a primary refining step;introducing to the cellulosic material at least one of a chemical agent and a biological during the pre-treatment step or the primary refining step; and outputting a refined and defibrated cellulosic material from the primary refining step.
