Abstract
Process for the manufacture of paper, based on hydrated gelatinized cellulosic fibers and un hydrated cellulosic fibers, characterized in that it comprises draining water from a mixture containing 3 to 40% of unhydrated cellulose fibers and 60 to 97% hydrated fibers, based on the combined weight of the fibers, and hydrate the hydrated fibers to an equivalent of a refined Schopper-Riegler less than 340 cc.
