Bagasse, an industrial agro waste is treated with alkali initially to remove hemicelluloses fraction followed by treatment with sodium chlorite solution varying the treatment time. The novelty of the work lies in the bleaching with chlorite treatment in alkaline medium. The treated bagasse fiber was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), particle size analysis by dynamic light scattering technique (DLS), optical microscope, scanning electron microscope (SEM), atomic force microscope (AFM), UV spectroscope, and thermogravimetric analysis (TGA). It was found that during alkali treatment, a lattice transformation from cellulose I to cellulose II took place. Chlorite treatment removed lignin initially, and then with increasing time, the amorphous portion of cellulose is removed, rendering high crystallinity in the fiber. All the changes have been accounted by evaluation of LOI (lateral order of index), TCI (total crystallinity index), and HBI (hydrogen bond intensity) from FTIR study. XRD study also revealed the same fact. AFM study also supported the same fact indicating generation of sharp crystal and rough surface. Morphological study of treated and untreated bagasse fiber also exhibited fibrillation of fiber. Radius of hydration as estimated by DLS analysis followed a decreasing trend with increase in chlorite treatment time. The loss of transparency in cellulose fiber has been exposed by UV spectra analysis. TGA study showed that thermal stability has been increased with chlorite treatment. Such alkali treatment along with sodium chlorite for cellulose extraction from bagasse has not been performed by earlier investigators. Extracted cellulose fiber will be a very suitable reinforcing agent due to highly fibrillated morphology.

最初用碱处理工业废料蔗渣，以除去半纤维素部分，然后用亚氯酸钠溶液处理，改变处理时间。这项工作的新颖之处在于在碱性介质中用亚氯酸盐处理进行漂白。通过傅里叶变换红外光谱（FTIR），X射线衍射（XRD），通过动态光散射技术（DLS）进行的粒度分析，光学显微镜，扫描电子显微镜（SEM），原子力显微镜（AFM）对经过处理的蔗渣纤维进行表征），紫外光谱仪和热重分析（TGA）。发现在碱处理期间，发生了从纤维素I到纤维素II的晶格转变。亚氯酸盐处理首先去除了木质素，然后随着时间的增加，去除了纤维素的无定形部分，使纤维具有高结晶度。通过FTIR研究评估LOI（指数的侧向顺序），TCI（总结晶度指数）和HBI（氢键强度）可以说明所有这些变化。XRD研究也揭示了相同的事实。原子力显微镜研究也支持同样的事实，表明产生了尖锐的晶体和粗糙的表面。经处理和未经处理的蔗渣纤维的形态学研究也显示出纤维的原纤化。通过DLS分析估计的水合半径随着亚氯酸盐处理时间的增加而呈下降趋势。纤维素纤维中透明度的损失已经通过紫外光谱分析暴露出来。TGA研究表明，亚氯酸盐处理可提高热稳定性。早期的研究人员尚未进行过这种碱处理以及亚氯酸钠从蔗渣中提取纤维素的研究。由于高度原纤化的形态，提取的纤维素纤维将是非常合适的增强剂。
