    摘要: Provided by this invention is a modified synthetic polyamide polymer yarn produced by an improved melt extrusion process. Yarn of this invention are either partially oriented yarns (POY) or drawn oriented yarns. The improved process provides for modification of a polymer in a melt extruder. Following this modification of the polymer, a filament forming process step is provided which is coupled to a drawing stage prior to winding a package of yarn.
