Abstract

A method of processing a high ethylene random copolymer comprising nucleating a high ethylene random copolymer to form a high ethylene polymeric composition, melting and extruding a high ethylene polymeric composition, spinning a high ethylene polymeric composition to form a fiber, cooling the fiber, guiding the fiber with an aspirator, and recovering the fiber.
