The present work aims to analyze the influence of chemical treatment on thermal, morphological, mechanical, and water absorption characteristics of a new natural Bauhinia Vahlii (BV) stem fiber. In this research study, the BV fiber surface was modified through different chemical treatments such as alkalization, bleaching, and benzoylation. The effect of these chemical treatments on the fiber are visualized through the scanning electron microscope (SEM) micrographs. SEM ensures the presence of voids and rough surfaces with the removal of deleterious substances from the fiber. The results obtained from Fourier transform infrared ensure the presence of cellulose, hemicellulose, and lignin compounds in the case of untreated and treated BV fiber. Also, X‐ray diffraction analysis gives a higher crystallinity index for treated BV fiber. Thermogravimetric analysis confirms there is an increase in the thermal stability of the fiber after chemical treatment. The increase in tensile strength and young's modulus confirms improvement in the mechanical properties of the BV fiber after chemical treatment. The water absorptivity test ensures there is a reduction in the hydrophilic nature of the BV fiber after chemical treatment, which promotes better adhesion between fiber and matrix.

新型天然紫荆花茎纤维的综合表征
本工作旨在分析化学处理对新型天然紫荆花的热，形态，机械和吸水特性的影响。（BV）茎纤维。在这项研究中，BV纤维表面通过不同的化学处理（例如碱化，漂白和苯甲酰化）进行了改性。这些化学处理对纤维的影响通过扫描电子显微镜（SEM）显微照片可视化。SEM确保从纤维中去除有害物质，从而确保存在空隙和粗糙表面。在未经处理和未经处理的BV纤维的情况下，从傅立叶变换红外获得的结果可确保存在纤维素，半纤维素和木质素化合物。此外，X射线衍射分析可为处理过的BV纤维提供更高的结晶度指数。热重分析证实化学处理后纤维的热稳定性有所提高。抗拉强度的提高和年轻化 s模量证实化学处理后BV纤维的机械性能有所改善。吸水率测试可确保化学处理后BV纤维的亲水性降低，从而促进纤维与基质之间的更好粘合。
