Abstract

A Process of producing fiberboard according to the wet method in a closed backwater system. Chips of lignocellulose-containing material after defibration to pulp are suspended in backwater so as to obtain a pulp suspension for forming of wet sheets, which are liberated from water by compression under supply of heat, the squeezed-out water being returned to the suspension step. The pulp obtained in the defibration is dewatered mechanically and the obtained aqueous solution of organic substance released during the defibration step is used for impregnation of the chips prior to the defibration, whereby said substance is bound in the pulp.
