FIELD: textile industry. SUBSTANCE: method involves extruding polymer solution of 20-90 P viscosity through spinneret openings to form polymer flows of equal diameter de in settling bath with settler concentration value exceeding threshold concentration value by 1.5- 2.5 times; stretching filament or small cord to diameter d1 and allowing it to harden. Diameters ratio d1 and de is 0.65-0.92. Method provides for uniform diameter of filaments through its entire length. EFFECT: simplified method, increased strength and improved quality of filaments and cords. 1 dwg, 6 ex
