Development of disposable and degradable synthetic fibres for textile industry by chelating dual/multiple metal ions masterbatch technology

This project will be divided into two sections. The first part is to develop a metal chelating technique to stabilize metallic pro-oxidants for degradable fibres with a controllable shelf life. And formulate novel recipes for three popular synthetic fibres (polyester, polyamide and acrylic) and to prepare degradable masterbatches accurately by using tailor-made twin-screw system with vacuum drying chamber. Then, the degradable synthetic fibres can be fabricated by melt spin system finally. The second part of the project is to develop a control mechanism for producing degradable fibres with desirable life span. Producing degradable polyester, polyamide and acrylic synthetic fibres would be the first of its kind in the textile industry. The major focus area is the disposal plastic fibres and products. The project deliverables can be applied to textile and apparel, medical and personal healthcare, as well as packaging and environmental industries using disposal plastic products.
