  • Apparatus and method for melt spun production of non-woven fluoropolymers or perfluoropolymers
    Publication number: 20110076907
    Abstract: Disclosed is an apparatus, process, and product allowing for the manufacture of non-woven fluoropolymers, perfluoropolymers, and high temperature engineering resin filaments obtained from low melt index polymers. The fibers have continuous structural integrity created by using a heated duct that provides for maintaining an elevated filament temperature during filament draw down. The apparatus allows for entanglement and melt bonding of the fluoropolymers perfluoropolymers, and high temperature engineering resin filaments.

  • Self-crimping fluoropolymer and perfluoropolymer filaments and fibers
    Publication number: 20090197080
    Abstract: Disclosed is a method and device for creating three dimensional (3D) self-crimping fluoropolymer(s) and perfluoropolymer(s) filaments via extrusion through a spinneret plate orifice with a hole and elliptical gap and using die swell to close the elliptical gap in the filament forming a seam causing uneven stresses in the longitudinal length of the filament while cooling thereby causing the filament to self-crimp toward the seam.
