Pine apple leaf fibre (PALF) is an agro residue, extracted by scratching of pineapple leaves followed by retting. PALF has desirable properties of a textile fibre like high cellulose content, good tensile strength and fibre length. Research works were carried on development of various products by blending with fibers with or without physical/ chemical modifications. However the utilization of PALF in the conventional apparel and technical textiles is not fully explored. This is the right time to review the existing extraction methods, retting processes and chemical modifications for PALF, in order to identify the suitable research approaches for its effective utilization.
