This invention pertains to melt spun fibers of copolymers formed from tetra- fluoro ethylene and perfluorovinyl monomers and a process for their formation. In the process of this invention fibers exhibiting high strength and low shrinkage are drawn from the melt at SSFs of at least 500 x.
L'invention concerne des fibres filées à chaud de copolymères formés à partir de monomères de tétra-fluoro éthylène et de perfluorovinyle et leur procédé de fabrication. Dans le procédé de l'invention, des fibres à résistance élevée et à faible retrait sont étirées à partir de la matière fondue à des vitesses d'extrusion (SSF) au moins 500 fois supérieures.
