PLA and PHBV are 100% bio-based, biodegradable, nontoxic and biocompatible polymers. This project developed technologies for low temperature yarn texturing and dyeing processes in shorter time made from PHBV/PLA fibre. The production process achieves high dye uptake and colour fastness. The textile products have naturally anti-bacterial and mite-resistant properties without using any additional chemical agents. New antimicrobial yarns, knitted and woven fabrics, socks, compression stockings, shoe uppers and wound dressing such as non-adherent absorbent pad and bandage were developed by the technology of bio-based PLA/PHBV fibres. These products and technology have wide range of potential application in hospital, healthcare clothing and home textiles. Research Institute The Hong Kong Polytechnic University
