This project made use of 100% bio-based and degradable PHBV/PLA fibers to develop a low temperature dyeing process for creating new functional textiles. This green production process of disperse dyes achieves high dye uptake and colour fastness. The process can save 32% energy compared with that for dyeing PET fabrics. The resulting textiles have outstanding natural anti-bacterial and mite-resistant properties without using any additional chemical agents. The research has explored high-value functional applications like medical textiles, home textiles, intimate apparel and footwear. The developed fabrics have soft and smooth hand feel, excellent anti-pilling and anti-snagging performance, thermal conductivity and drapability.
