摘要：

This study deals with a series of operations to isolate the micro-cellulose from the palm tree spathe sheath by using a modified chemical method to take into account the low cost and the completion speed and its characterization using X-ray diffraction technique (XRD), infrared spectroscopy (FTIR) and scanning electron microscope coupled with element analyzer (SEM/EDX). The results showed that the extraction method succeeded in obtaining very pure microscopic fibers with a width of 2-10 mu m with a crystallinity index equal to 79.21%, containing the two cellulose features I beta and II, that, the conversion ratio of the first to the second was estimated at 32, 87%.
