FIELD: pulp and paper production.
SUBSTANCE: invention relates to pulp and paper production, particularly, to production of glued fibrous products. Method of preparing a fibrous composition for paper involves contacting cellulose fiber with a sizing composition consisting of a neutral catalyst for polycondensation reaction of resin, a moisture-resistant agent and a nonionic surfactant, in series and/or simultaneously, followed by composition dehydration, pressing and drying. Water-resistant agent used is trimethylated melamine-formaldehyde resin stabilized with ethylene glycol when mixed with water at ratio of 1:2 to 1:2.5 weight fractions, with average pH from 6.5 to 7.4.
EFFECT: higher strength of paper in wet and dry state, as well as improved stability of sizing composition in neutral medium.
