FIELD: fiber production. SUBSTANCE: filaments are manufactured from melt of copolymers formed from tetraflouroethylene and perflourovinyl monomers. Method involves drawing filaments from melt with flow rate of 1-30 g/10 min at least 500 times. Method provides manufacture of filaments having strength of at least 190 MPa and shrinkage less than 15%. EFFECT: simplified method and improved qualities of filaments. 17 cl, 3 dwg, 5 tbl, 12 ex
