| titleOfInvention | Process for producing paper |
| abstract | In the present invention, there is disclosed a process for producing paper from an aqueous suspension containing cellulose fibers and optional fillers. Process comprises separately adding to the suspension cationic processing polymer with one or several aromatic groups and anionic polymer with one or several aromatic groups. The latter is selected from polymers prepared according to stepped molecule growth mechanism, naturally occurring polysaccharides and aromatic polymers and modifications thereof, provided that, if anionic polymer is polymer prepared according to stepped molecule growth mechanism, then it cannot be anionic condensation polymer based on melaminesulfonic acid. Another condition that could be alternatively fulfilled is that anionic polymer is not anionic polystyrenesulfonate or anionic condensation polymer based on melaminesulfonic acid. Suspension is then molded into sheet and dehydrated on screen. |
