The crystallite sizes and degrees of lattice distortion of annealed PET fibers have been determined with the variance-range functions of 105 diffraction profile with the assumption that the crystallites in the materials are paracrystalline. The corrections of the diffraction profile data were simple and reliable because there was not any overlapping with other reflexions in tie range of 2θ=35°—51°.
It has been shown that: (1) the use of the variance-range function for the determination of crystallite size results in a “number-average” size; (2) annealing produces larger crystallite sizes and smaller degrees of lattice distortion; (3) the correlation between the crystallite sizes and distortion factors is in od agreement with Hosemann′s a~* law~[11].
