Assessment of selected structural parameters of long-staple cottons

The object of the examinations we performed was to establish the impact of climatic conditions governing the growth of a cotton plant on the supermole cular structure of cotton. Long-staple cottons originating from various agr o-climatic areas were examined, in particular the following cottons: the Eg ypt-Giza, Sudan Baracat, India MCU-5 and USA Pima. The following examinatio ns were performed: wide-angle (WAXS) and small-angle (SAXS) x- ray diffract ion; examination of the cross section of cotton fibres with the use of JSM- 15 JEOL scanning microscope, together with examinations performed tinder in fra-red conditions. On the basis of WAXS and SAXS examinations the degree o f crystallisation, the size of crystallites, and the fibre texture were det ermined. Insignificant differences in the structures of the examined sample s were recorded.
