Production polyamide yarn, fibers or filaments comprises spinning and/or drawing in the presence of an electric field to modify mechanical properties

摘要

Production of polyamide yarn, fibers or filaments by spinning a molten polyamide-based composition to produce a filament or bundle of filaments and optionally drawing the filament(s) during or after spinning comprises exposing the filament(s) to an electric field over at least part of the spinning and/or drawing path.
