Abstract
Process for making high strength paper comprising providing a pulp produced by mechanically treating a high consistency cellulosic pulp, substantially defibrated between two rough, opposite surfaces, having movement in relation to each other and separated by a distance greater than the thickness of the fibers which are being treated to cause friction between the fibers, twist and fibrillate them without substantially cutting the fibers, mix the pulp with sufficient water to form a pulp of low consistency, form said pulp as a continuous sheet of wet paper and then dry said sheet of paper to produce a paper having increased characteristics of strength, toughness and tear resistance.
