Pineapple leaf fibre (PALF) is a natural cellulosic fibre extracted from pineapple leaves, a sustainable by‑product of pineapple farming. It is white, silky, and fine‑textured, with high tensile strength, good moisture absorption, and natural antibacterial properties. Widely used in textiles, composites, and eco‑friendly materials, it offers a green alternative to synthetic fibres.
