FIELD: production of fibril system filaments. SUBSTANCE: fibril systems contain at least one macromolecular film-forming polymer, and they have structure in which fibrillated filaments with diameter of 10 microns or less are branched from main filaments having width within the range of 0.1-500 microns and length within the range of 10 microns to 10 cm. Fibril systems of such structure may be used for manufacture of filters and may be used as artificial leather. EFFECT: wider range of usages of fabric produced from fibril systems and simplified manufacture method. 23 cl, 32 dwg, 5 tbl, 5 ex
