摘要

Cold draw processing of poly(ethylene terephthalate) yarns has been discovered that yields a sheath/fibrillar core (s/fc) microstructure in the each fiber of a yarn.When aged,unoriented,noncrystalline spun yarns were cold drawn,high(>5.7:1) draw ratios could be achieved and an s/fc microstructure resulted.Cold drawing also generated a high oriented amorphous content.The tensile and shrinkage properties of yarns wiht the s/fc microstructure and high oriented amorphous content were examined as function of processing (drawing,annealing,and relaxing).The microstructure was examined by scanning electron microscopy,transmission electron microscopy,smallangle X-ray scattering,wide-angle X-ray scattering,and optical microscopy.The fibrillar microstructure survives all processing.Management of the oriented amorphous component under heat and tension contributes to the greater stiffness (modulus) and dimensional stability of processed s/fc yarns.The properties of yarns with an s/fc microstructure are compared with more conventional hot drawn yarns.
