Special Features of X-ray Analysis of Cellulose Crystallinity and Content in Flax Fibres

Resumo

Experimental X-ray diffraction analysis procedures and calculation algorithms are proposed for determining the degree of crystallinity of flax fibres of varied purity and their cellulose component from the integral values of diffraction by the crystallite regions of the analysis sample and the reference standard, which are normalized, taking account of the scattering mass of the preparations. The possibility of determination of the mass cellulose content in flax fibres by X-ray analysis, which dispenses with the need for labor and time consuming chemical analyses, is substantiated.
