Abstract
Fibers and yarns of polyethylene terephthalate (PET) and PET copolymers with a sheath/filamentous core microstructure are formed from unoriented and non crystalline 'as spun' source fibers and yarns by drawing to high draw ratios in one step. Fibers and yarns with the sheath/filamentous core microstructure are stiffer than commercial PET fibers. Fibers and yarns with the sheath/filamentous core microstructure may be annealed and relaxed to increase their dimensional stability without loss of the sheath/filamentous core microstructure.
