Exploring Selected Natural Fiber Characteristics though XRD and FTIR Analysis for Textile Applications

<p>Purpose: This study aims to explore the structural and chemical properties of natural fibers in order to<br>inform their selection and optimization for sustainable textile applications.<br>Design/methodology/approach: X-ray Diffraction (XRD) and Fourier-transform infrared spectroscopy<br>(FTIR) were employed to analyze and characterize five natural fibers: bamboo, calotropis, kapok, modal,<br>and nettle.<br>Findings: Significant differences in crystallinity levels were observed among the fibers, with bamboo<br>exhibiting high crystallinity attributed to its cellulose composition, enhancing mechanical strength and<br>durability. Calotropis fibers, on the other hand, demonstrated lower crystallinity due to their<br>proteinaceous nature, offering unique properties for specific applications. FTIR analysis provided<br>insights into the molecular structures of the fibers, with modal fibers showing a higher degree of<br>molecular order and kapok fibers exhibiting a more amorphous structure, contributing to their<br>lightweight and breathable qualities.<br>Originality/value: This comprehensive analysis contributes valuable insights into the structural and<br>chemical properties of natural fibers, facilitating informed decision-making for sustainable textile<br>applications and meeting consumer demands for eco-conscious products.</p>
