FIELD: textiles, paper.
SUBSTANCE: first the straw is cut into pieces of the predetermined length, then the straw is refined by passing the chopped straw of the predetermined length through the disk-type refiner with the energy consumption of less than 150 kW/t. The refined straw is sorted for separation of the refined straw to separate fractions containing pure bast fibres, coarse bast fibers, coarse core and dust.
EFFECT: invention enables to obtain fibers of a predetermined length.
