In X-ray diffraction analysis studies for different pulping methods in this study, it was found that the half height width (H.H.W.) do not vary much from one method of pulping to the other, but they are all lower than that of the starting bagasse. Moreover, the crystallinity indices for different bagasse pulps are in good agreement with the results of IR-spectra for these pulps where, it was found that, the higher crystallinity index is for (AO) and PA-EDTA bagasse pulps while, the lower crystallinity index is for curde bagasse. Moreover, it was found that the interplanar spacing (d) values of different bagasse pulps are slightly affected by the pulping methods. In case of bleached bagasse pulps, it has been found that, the (H.H.W.) of bleached different bagasse pulps is lower than that of unbleached pulps. However, it has been also found that the crystallinity indices of bleached different bagasse pulps were higher than that of unbleached bagasse pulps. Moreover, the interplanar spacing (d) values for bleached different pulps are also slightly affected during bleaching process.
