Abstract

Process for treating pulp for paper making comprising: (a) introducing a substantially defibrated pulp of high consistency containing cellulose fibers separated in space formed by two rough, opposite surfaces, which are in relative movement with each other, and spaced by a distance greater than the thickness of the introduced fibers . (b) subjecting the pulp to a mechanical treatment in said space under the compression exerted by the said surfaces moving with a sufficiently high relative tangential velocity and under an input of sufficient force to cause friction between the fibers, the twisting and the fibrillation of the fibers without substantially cutting the fibers while the pulp moves rapidly and continuously through said space in a direction away from the point of introduction to the point of its discharge and (c) discharging the treated pulp from said space thereby producing a pulp for the manufacture of high strength paper having increased characteristics of bursting strength, tensile strength, tear strength, stretch resistance and toughness.
