FIELD: chemistry.
SUBSTANCE: first, a microscopically homogenised solution is obtained by dispersing 75-25 vol. % cellulose and 25-75 vol. % of at least another fibre-forming polymer in a water-containing ionic liquid while adding stabilisers and completely removing water using shear, temperature and vacuum. The solution is formed through at least one die hole into a fibre or bundle of fibres, which is directed through a conditioned gap while drawing in order to deposit directed jets of the solution via treatment with a temperature-controlled solution of a precipitation agent for cellulose and another fibre-forming polymer, mixed with an ionic liquid so that spinodal layering takes place. The directed jets of the solution are removed from the settling bath and undergo subsequent treatment.
EFFECT: obtained fibre has low swelling capacity and high resistance to wet wearing.
