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.
