FIELD: manufacture of fibrous materials, in particular, cardboard.
SUBSTANCE: method involves first subjecting secondary filament-waste paper to breaking-up procedure in hydraulic breaker at temperature of 37-390C and pulp concentration of 2-4%, followed by processing in thermal dispersion apparatus at temperature of 38-550C and pulp concentration of 10-12%.
EFFECT: improved physico-mechanical properties of fibrous materials produced and reduced power consumption.
