this paper shows how the crystallite orientation angle obtained from x-ray diffraction patterms can be used for varietal characterization of cotton at the molecular level. the 40 and 50 x-ray angles are usually taken as representative parameters to correlate with the strength of the fiber. although the 50 x-ray angle has some theoretical justification, like the use of the half-width of spectral lines, the choice of the 40 x-ray angle is arbitrary. from the study of 24 gossypium hirsutum cotton varieties reported in this paper, it is observed that the average angle of orientation $alpha$ //m evaluated from the hermans orientation factor f//c gives better correlations with mechanical properties than the 40 and 50 x-ray angles conventionally used. 36 refs
