FIELD: textiles, paper.SUBSTANCE: invention relates to chemical technology of cellulosic materials and relates to cellulosic nano-filaments and the method of their production. The nano-filaments are thin filaments with a width of micron interval, the length of 2 mm, and made from natural fibres of wood and other plants. The nano-filament surface may be modified so that it comprises anionic, cationic, polar, hydrophobic or other functional groups. Insertion of the nano-filaments in the batch to obtain paper improves significantly the strength of the wet cloth and strength of the dry sheet much better than the existing natural and synthetic polymers.EFFECT: invention provides creation of the cellulosic nano-filaments which are excellent additives for reinforcing paper and cardboard products and composite materials, and may be used for obtaining superabsorbents.18 cl, 10 dwg, 6 tbl, 11 ex |
