Characterisation of Sodium Acetate Treatment on Acacia pennata Natural Fibres

Abstract

The present study concerns the physico-chemical, structural, mechanical and thermal characterization of Acacia pennata, a natural and almost inexpensive fibre, as a potential reinforcement in polymer composites. The effect of treating the fibre with sodium acetate to increase its qualities has been seen through the use of thermogravimetric analysis, scanning electron microscope (SEM) analysis, X-ray diffraction (XRD), mechanical property tester, and Fourier transform infrared spectroscopy (FTIR). According to XRD analysis, the elimination of lignin and wax-like impurities resulted in an increase in the AP fibre’s crystalline index (79.73%). The fibre’s thermal stability was also discovered to be 365 °C. Tensile strength (557.58 MPa) and elongation at break both increased by 2.9% after treatment with sodium acetate. The surface nature and quality of AP fibres improved after sodium acetate treatment. It was confirmed by the reduction of chemical compositions (such as hemicellulose, lignin and pectin). Given its density, the fibre can be suggested as a reinforcement in polymer composites for light-weight applications because its lightweight property will be more useful for composite manufacturing.

“…Finally, the density was measured using the method SITRA/TC/FCC/03. All these methods are specific techniques followed to determine the chemical constituents of any natural fibre by SITRA, Coimbatore, Tamil Nadu, India, where the samples were sent for chemical analysis 23 , 68 .…”

“…Furniture, railroad ties, automobile frames and carpeting, horticultural supplies, packing material, and essentially any use that does not demand a high level of mechanical tolerance but instead requires affordable purchase and low maintenance are examples of already-explored industrial applications. Additionally, swapping out raw polymers with recycled material is easy and practical, improving both economic effectiveness and environmental sustainability 20 – 23 .…”

Characterization of novel natural cellulose fiber from Ficus macrocarpa bark for lightweight structural composite application and its effect on chemical treatment

“…Literature indicates that chemical treatments are particularly effective in removing significant quantities of amorphous constituents like hemicellulose, pectin, lignin, wax, and impurities from the surface of the fibers by breaking down the hydroxyl groups. This removal substantially increases the cellulose-to-amorphous constituent ratio, thereby improving the performance properties of the plant fibers [ 12 ]. Additionally, chemical treatment makes the surface of plant fibers rougher.…”
