摘要

The increasing demand for sustainable and eco-friendly materials has led to a rise in the use of non-wood plant materials as textile fibre resources. In India, Sesbania aculeata, referred to as dhaincha locally, is one such underutilised agricultural resource. Dahincha was only utilised for green manuring before the cultivation of paddy and sugarcane. The coarse fibre from the dhaincha plant is strong enough to be used in a variety of sustainable and technical textile industries. Therefore, the purpose of this study was to extract fibre from dhaincha stems and to improve the physical properties of dhaincha fibres, mainly fibre fineness, bundle strength, and elongation, with a pretreatment process. The dhaincha fibres were retted for 8, 15, and 22 days. Dhaincha fibres retted for 15 days were further used for experimentation, which involved the pretreatment of dhaincha fibres with various chemicals and enzymes. The physical properties of pretreated dhaincha fibres were analyzed by using the Duncan Post Hoc test, which helped to ascertain the particular group means that were substantially different from one another. Dhaincha fibres treated with sodium sulphide showed better fineness, bundle strength, and elongation properties. The optimization of conditions was carried out by using the Response Surface Methodology of the Box–Behnken experimental design was used to examine the correlation between three variables and three responses by providing 17 different experimental values¸ which were carried out one by one in the laboratory. The pretreated dhaincha fibres were further evaluated for their characterization by using Scanning Electron Microscope and Fourier Transform Infrared Spectroscopy. The statistical analysis (ANOVA) was carried out in order to establish the relationship between the concentration of Na2S, temperature, and time with fibre fineness, bundle strength, and elongation. The physical properties of dhaincha fibres highlight the sustainable use of the dhaincha plant in the textile sector as well as in the pulp and paper industry.
