Orientation distribution of crystallites in polyethylene terephthalate fibers (original) (raw)

This research investigates the orientation distribution of crystallites in polyethylene terephthalate (PET) fibers, highlighting the significance of the (705) plane for evaluating the Hermans orientation function. The study derives a more accurate estimate of the Hermans orientation function through azimuthal scans and presents an analytical method that improves upon previous calculations by addressing off-meridional effects. The results demonstrate variations in crystallite orientation based on heat-setting temperatures, providing valuable insights into the structural properties of PET fibers.
