|Title:||Analysis of structural parameters of acid and alkali treated polyester fibers using SAXS and other techniques|
Behera, R C
|Abstract:||Analysis of structural parameters of normal and chemical (acid and alkali) treated polyester fibers has been done using small angle X-ray scattering (SAXS) technique. Average diameters have been calculated from scanning electron microscope (SEM) micrographs and mechanical parameters have been estimated using Instron. Further, crystallinity parameters of the same fibers have been determined using X-ray diffraction (XRD) and thermal analysis. These results supplement the findings of SAXS, SEM and Instron. Comparison and analysis of results confirm some changes in the microstructure of fiber after chemical treatment due to readjustment of macromolecules. The findings conclude that degradation of fiber treated in strong acid is more prominent than other treated fibers. No specific changes are observed in case of sample treated in weak acid. Increase in crystalline parameters of fibers treated in weak alkali indicates cross-linking.|
