FIELD: chemistry.
SUBSTANCE: fibre is impregnated in centrifuge with modifying water composition, with module 2.5-3.5. Fibre is kept in modifying composition for 10-30 minutes in static state, then in rotating centrifuge at rate 800-1200 rev/min for 10-30 minutes. Fibres are pressed up to residual moisture content 70-90% and dried to residual moisture content 5-14%.
EFFECT: method is economical due to reduction of amount of technological equipment; obtained cellulose fibres possess high parameters of flame retardation and resistance to wet treatment.
