Changes in the structure of polyethyleneterephthalate (PET) (Egyptian woollen type) übres, with strain produced by diþ erent stresses, are evaluated from optical and density measurements. Calculation of the optical parameters is carried out using two-beam interference fringes, and the density data a

The orientation of the noncrystalline (amorphous) phase in poly (ethylene terephthalate) fibers is analyzed by separating the amorphous scattering in the wideangle x-ray diffraction patterns into isotropic and anisotropic components. Two parameters are used to characterize the amorphous orientation-
