The processes and apparatus of the present invention concerns melt spinning high
viscosity fluoropolymers into single filaments or multi-filament yarns at high
spinning speeds, the melt spinning being carried out at a temperature which is
at least 90 C. greater than the melting point of the polymer or in the case
of perfluoropolymer, at a temperature of at least 450 C., and the yarns produced
by the process, wherein the filaments can exhibit an orientation at the surface
of the filament no greater than at the core of the filament.
