ABSTRACT:
The invention relates to the production of a wholly mechanical pulp of improved strength properties. The lignocellulosic material is fed into a substantially closed chamber where it is mechanically abraded under a power input of fifteen or more horsepower days per ton. During the abrading step, the material is maintained in an inert gaseous atmosphere of a pressure of ten to eighty psig, preferably twenty to forty psig.
