Abstract

A PROCESS FOR THE MANUFACTURE OF CELLULOSE PULP FROM WOOD MATERIAL IN PARTICULATE FORM COMPRISES THE STEPS OF IMPREGNATING THE MATERIAL WITH DIGESTION CHEMICALS IN THE FORM OF AN AQUEOUS SODIUM SULPHITE SOLUTION AND THEN DIGESTING THE TREATED MATERIAL. FURTHER DIGESTION CHEMICALS ARE ADDED FOLLOWED BY MECHANICALLY REFINING THE MATERIAL TO PREDOMINANTLY WHOLE FIBERS. THIS STEP IS THEN FOLLOWED BY A FURTHER DIGESTION STEP WHEREAFTER THE RESULTANT PULP MAY OPTIONALLY BE FURTHER MECHANICALLY REFINED.(FIG. 1)
