A continuous-filament yam made by extruding a synthetic polymer so that a substantial degree of molecular orientation is present in the resulting filaments, but further molecular orientation is possible.
Note.1: The resulting yarn will usually require a positive draw-ratio in subsequent processing in order to orient fully the molecular structure and optimize tensile properties.
Note 2: Yarns of this type made by high-speed spinning are commonly used as a feedstock for producing draw-textured yarns.
