A pulp making process in which fibrous cellulosic material is pulped to form an aqueous suspension of cellulosic material, the suspension is drained through a screen to form a pulp sheet and that the pulp sheet is dried to form a dry market pulp, in which a water soluble cationic polymer is added to the suspension as the sole drainage aid wherein the water-soluble cationic polymer is either, The process of the invention provides improved drainage time and solids content of the dewatered pulp.

Manufacture of cellulosic pulp sheets

A method for the production of paper, cardboard and card by adding a microparticle system consisting of a polymer retention agent having a molar mass Mof at least 2 million and a fine-part inorganic component in order to form a paper material having a material density of a 20 g/l maximum and by dewatering the paper material, wherein the paper material undergoes at least one shearing step prior to or after addition of the retention agent and wherein the retention agent is introduced in a dosed manner into the paper material in at least two places and the fine inorganic component is dosed prior to or after addition of the retention agent or between two dosing points for the retention agent.
