New Functional Textiles from Bio-based and Degradable Fibres

This project successfully developed technologies for low temperature yarn texturing and low temperature dyeing processes in a shorter time for green textile products made from PHBV/PLA fibres. PLA and PHBV are 100% bio-based, biodegradable, nontoxic and biocompatible polymers. Although having good spinnability, PLA has low heat resistance, and high rigidity and brittleness after long-term storage. It is difficult to apply to textile processes such as yarn texturing, dyeing and finishing. PHBV is widely used in the production of plastic goods, but because of its poor spinnability and high brittleness, it is rarely used in the textile industry. The blending of PHBV and PLA into textile fibres provides greater heat stability and softness than is the case with pure PLA fibres.

A non-exclusive licensing agreement covers spinning, knitting, dyeing and finishing of the PLA/PHBV yarn and fabrics, production technology of the compression stocking and 3D printing technology for the flexible biomedical materials with complex porous structures.
