in this work. Cellulose content was found to be increased after alkalization due to the removal of the non-cellulose substances,which was evidenced by attenuated total reflectance-Fourier transform infrared(ATR e FTIR) spectroscopy spectrum analysis and thermogravimetric analysis(TGA) measurements. The highest cellulose content was obtained in the bleached fibers. TGA analysis revealed an improvement......
