BJ-04. Harnessing Pineapple Leaf Fiber (PALF) for Sustainable Yarn Manufacturing: A Review of Plant-Based Fiber Technologies, Challenges, and Future Prospects

Abstract

The global textile industry's increasing emphasis on sustainable development has necessitated the search for eco-friendly alternatives to synthetic fibers. Pineapple Leaf Fiber (PALF), an agro-waste byproduct of pineapple cultivation, presents an outstanding opportunity to address these needs due to its favorable mechanical properties, biodegradability, and abundant availability. This review comprehensively explores PALF's extraction, processing, spinning technologies, and the mechanical and physical properties of PALF-based yarns. Comparative analyses with other natural fibers, such as cotton and polyester, reveal PALF’s industrial potential. Additionally, recent innovations, challenges in mass production, economic viability, and the future prospects of PALF-based yarns within the framework of a circular economy are critically discussed. By bridging fundamental research with practical applications, this review aims to contribute to the development of a sustainable fiber ecosystem.
