Popis:	Melt spinning of a fluorocarbon copolymer of tetrafluoroethylene and hexafluoropropylene was performed for the first time under various conditions with the take-up velocity up to 800 m min-1 and the draw ratio up to 2.5. The fine long filaments with diameters of 20-60μm were obtained. The molecular orientation in the fiber developed and the melting peak in the DSC thermogram sharpened with an increase in take-up velocity as well as in draw ratio. The mechanical properties of the fiber varied from 0.271 to 1.26 GPa in Young’s modulus, from 0.0285 to 0.137 GPa in the break stress and from 300 to 25% in the break strain under the spinning condition, respectively.
