Physical Properties of Isolated Cellulose Fiber from Jute and Banana Fiber through Kraft Pulping: Promising Applications in Packaging and Regenerated Fibers

Abstract Cellulose, a naturally abundant biopolymer, holds great potential as a sustainable alternative to synthetic fibers. However, the lack of knowledge and awareness regarding cellulose usage, especially derived from agricultural sources, has impeded the full exploitation of this highly biodegradable resource. This study aimed to extract and characterize cellulose from jute and banana fibers. The extracted cellulose exhibits a light yellow to white color, and microscopic analysis of the fibers showed micro fibrils. X-ray Diffraction (XRD) characterization indicated that the cellulose samples encompass both cellulose-I and cellulose-II structures. Moreover, increasing the M:L ratio of alkali enhanced the percentage of cellulose extraction. The findings of this study carry significant implications for the efficient production of cellulose fibers, with diverse applications spanning from high-volume products like regenerated fibers, automotive parts, packaging, absorbent products (diapers), textiles, and precast concrete, drug delivery mediums, electronics, additive manufacturing, bone and tissue scaffolding, and so on. This research opens the door to harnessing the potential of cellulose derived from jute and banana fibers in various industries.
