Abstract: Crystallinity, crystallite size and lattice distortion (rnicrostrain) of wild banana (Musa velutina) cellulose were studied using X-ray line broadening analysis. The degree of crystallinity of cellulose was found to be 45%. Microstrain and crystallite size were calculated for quantitative comparison along (002) and (040) directions using both paracrystalline (Hosemann) and integral methods (Cauchy and Gaussian assumptions) for separation of lattice distortion and crystallite size. The average crystallite size has been found to be 15.9 nm (corresponding to 20 cellulose unit cells) in (002) plane direction and 21.5 nm (corresponding to 21 cellulose unit cells) in (040) plane direction. The average microstrain has been found to be 0.33 in (002) plane direction and 0.54 in (040) plane direction. The banana cellulose fibres, however, are suitable for use as a raw material for textile and pulp-paper industries.
