ABSTRACT OF THE DISCLOSURE A method and apparatus of treating cellulose fibres in a cellulose pulp with a concentration of 10-90% with a liquid is disclosed. The pulp is intermittently given elastic compression forces and the cellulose fibres are subjected to pressure shocks with a duration not exceeding 1 second and of such a magnitude that the pressure in the interior of the fibres is increased to a valve exceeding 0.2 atmospheres excess pressure. The fibres are allowed to expand between the pressure shocks without remaining deformation and the treatment is maintained until complete impreg- nation and/or exchange of liquid enclosed in the fibres has been accomplished.
