摘要

Pineapple leaf fiber (PALF) represents a prolific but largely untapped lignocellulosic agricultural byproduct. Despite its commercial potential, a transition toward integrated biorefinery strategies is required to harness PALF for high-value applications, particularly in sustainable textiles. This review evaluates the conversion of raw PALF into functional woven and non-woven architectures, framed within the paradigms of cleaner production and waste valorization. We analyze how fiber morphology, chemical/enzymatic pretreatments, and bonding density dictate the final physicochemical characteristics of the textile. A comparative assessment reveals that while woven PALF mats provide superior mechanical tensile strength and dimensional stability for structural composites, non-woven mats offer enhanced thermal/acoustic insulation and scalability for bioleather and filtration media. Furthermore, this study addresses critical bottlenecks in the PALF value chain, including fiber quality variability and the environmental footprint of treatment residues. By integrating Life Cycle Assessment (LCA) perspectives, this review establishes a roadmap for the industrial adoption of PALF-based materials, aligning with global circular bioeconomy strategies and green manufacturing pathways.
