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.
