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.
