FIELD: chemistry.SUBSTANCE: polysaccharide or a polysaccharide derivative is adsorbed on fibres of a suspension cellulose material for at least 1 minute in the presence of monovalent or polyvalent cations, such as aluminium, calcium and/or sodium salts. The obtained fibrous suspension is subjected to mechanical disintegration with obtaining nanofilbrillated cellulose, modified with polysaccharide or the polysaccharide derivative.EFFECT: invention makes it possible to reduce an amount of energy, spent on defibration, as well as to obtain paper with improved qualities.23 cl, 6 tbl, 6 dwg, 2 ex |
