FIELD: textile, paper. ^ SUBSTANCE: according to one version, method includes provision of aqueous suspension that contains cellulose fibres. Addition of cation polysaccharide and polymer P2, which is an anion polymer, to produced suspension after all points of high polymer P1 shearing force, and P1 polymer is an anion polymer. Then water is removed from produced suspension to form paper. According to the other version, auxiliary agents are added for drainage and retention to produced suspension of cellulose fibres after all points of high shearing force. The latter are represented by a cation polysaccharide and polymer P2, being an anion polymer. ^ EFFECT: improved drainage without deterioration in retention and forming of paper, increased speed of paper-making machine and application of lower doses of polymer. ^ 34 cl, 5 tbl, 5 ex |
