Splitting and authentication of the newest retrieved cellulose-rich organic fiber from the exterior layer of Bangladeshi palmyra seed sprouts

Abstract

The upward trajectory of plant-based cellulosic fiber originating from renewable sources is crucial to visualizing a sustainable future. This article reports a freshly developed and distinctive natural fiber derived from palmyra seed sprout fibers (PSSF) by employing hot water retting. The hygroscopic behavior (moisture regain and content) density, bundle fiber strength, burning behavior, and chemical composition of the fiber are determined using ASTM D1909, ASTM D2654, ASTM D891-18, ASTM D1445, ASTM D1230-22, and TAPPI standards, respectively. Crystallinity, fiber configuration, biological groups, flame behavior, and temperature responsiveness are determined using XRD, SEM, FTIR, burn test, and TGA tests. The reported cellulose-rich textile fiber that contains 64% cellulose with average moisture recovery and content percentages of 14.38% and 12.56%, respectively. The envisioned fiber has an average tensile strength of 11.05 g tex⁻¹, a breaking extension of 1.8 mm, and a crystallinity of 38%. The highest temperature at which the fiber begins to deteriorate is 474 °C. This noble fiber can be utilized to create biological materials, cellulose nanoparticles, composites reinforced with fibers, and more.
