Abstract

Utilization of underexploited, unexplored natural fibres from crop waste are not only critical issues in the international scenario but are also the need of the hour in developing countries like India. Pineapple leaf fibre extracted from the green pineapple leaf, an agro waste reveals its immense potentiality in the field of textiles particularly due to the disposal problem after harvesting for cleaner and green environment. Blending of indigenous PALF with acrylic will help development of textiles with better functional properties by combining positive features of both the fibres. Blending of PALF/acrylic did not pose any problem in conventional jute processing system. Wet spun yarn exhibits better characteristics compared to dry spun one. The optimum stage of blending of the above fibres is carding stage. The critical blend level for 3 denier acrylic fibre and indigenous PALF has been found to be 74/26. The theoretical and actual blend composition estimated by chemical method reveals close matching with each other. The PALF/acrylic blended yarn has a bright future prospect for sustainable luxary textiles like fancy apparel products.
