Physicochemical characterization of lignocellulose fibers obtained from seedpods of Wrightia tinctoria plant

Abstract

Characterization of new innovative natural seed fibers from seedpods or fruits of various plants has increased popularly in textile, automotive, and construction industries due to various aspects, availability, and biodegradability. In addition, these fibers provide sustainable solutions to support technological innovation in numerous industrial applications. The current research aims to investigate the new lignocellulose fibers extracted from Wrightia tinctoria seedpods. The obtained Wrightia tinctoria seed fibers (WTSFs) were characterized via Scanning electron microscope (SEM), Fourier Transform Infrared-ray (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA), and Differential scanning calorimetry (DSC) to understand the fibers physicochemical properties. Complete experimental study of natural seed fibers of Wrightia tinctoria found to be a lignocellulose fiber and contains unique characteristics. Surface morphological studies reveal that, WTSFs contain smoother surface which is beneficial to develop a good bond with matrix while making composites. It does not get wet quickly with water due to fatty, wax, mineral matters, and higher lignin content on the fiber surface which means the fiber is soft compared with other natural seed fibers. These unique properties of WTSFs ascertain as a suitable material for polymer fabrication process, which would be favourable to develop good bonding with the matrix for making composites and also useful for insulating composite materials.
