A process for the production of paper |
abstract |
The present invention relates to a method for making paper from a suspension containing cellulose fibers and fillers, comprising separately adding an anionic polymer having an aromatic group and a cationic polymer having an aromatic group to the suspension, and forming and dehydrating the suspension on a wire. Is selected from condensation polymers, polysaccharides, natural aromatic polymers and modified substances thereof, and when the anionic polymer is selected from the condensation polymer, it relates to a papermaking process characterized in that it is not an anionic melamine-sulfonic acid condensation polymer. The invention also relates to a process for making paper from suspensions containing cellulose fibers and fillers comprising the steps of separately adding an anionic polymer having aromatic groups and a cationic polymer having aromatic groups to the suspension and forming and dehydrating the suspension on a wire. The polymer relates to a papermaking process characterized in that it is not anionic polystyrene sulfonate or anionic melamine-sulfonic acid condensation polymer. |
