Apparatus and method for melt spun production of non-woven fluoropolymers or perfluoropolymers

摘要

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.
