Method for preparing paper pulp, from a fibrous, lignocellulosic and non-woody plant material, characterized in that it includes the steps of moistening the fibers of the plant material and forming an aqueous suspension thereof, wetting the vegetable material by subjecting the suspension to a defibration operation whereby the cord is released from the fiber, further diluting the suspension of loosened cord and fiber, separating the cord and the fiber by sieving, partially draining the resulting fiber suspension, impregnating the fibers by adding a liquid to the suspension comprising an alkali hydroxide solution, and chemically digesting the fiber and the liquid by cooking at high temperature and under pressure.
