eng	Influence Of Beating And Chemical Modification On The Structural Characteristic Of Cellulose	The both chemical and mechanical influences upon supermolecular structure of cellulose represented by oxidative-hydrolysis process of oxycellulose preparation and beating of bleached linters, respectively, were studied by use of X-ray diffraction and X-ray computed microtomography methods. In order to elucidate a role of fines, hydrocolloids and dissolved substances in this context, the beating experiments were conducted with and without separation of these ones and the samples of paper sheets were prepared by usually drainage papermaking methods and by drying of pulp slurries at Petri dishes as well as. Received results suggest an increase of crystalline portion of cellulose during beating of native cellulose followed by deeply changes in their qualities in the case of oxycellulose.	cellulose;oxycellulose;microtomography;X-ray diffraction
