Effect of Potassium Permanganate treatment on physico-Chemical and mechanical properties of extracted Pine Needle Fiber

This study investigates the potential of extracted pine needle fiber (PNF) to substitute synthetic fibers in biopolymer composites as a reinforcing material. The is focused on surface modification and characterizing PNF. Water retting method was used extract PNF before being subjected potassium permanganate treatment. treatment with resulted higher density (1058 kg/m 3 ) compared untreated (1017 ). X-ray Diffraction (XRD) analysis shows treatments positively impacted natural fiber’s crystallinity index (CI). Additionally, tensile strength were found be enhanced from 49.67 ± 9.6 MPa (untreated PNF) 56.75 16.54 (treated PNF). Based findings, it can concluded that treated will suitable reinforcement fabricating ecologically friendly composites.
