Related Projects: Non-aqueous Solvent Medium (NASM) Dyeing for Textile

This project will focus on the development of a two in one non-aqueous solvent medium (NASM) dyeing system. The system would be able to specifically dye the yarn and garment respectively with an innovative design of dyeing vessel mechanism, in order to facilitate a uniform uptake of dye molecule on the substrate.

This innovation offers an alternative to traditional dyeing process, in which water acts as a solvent medium to dissolve the dyestuff and bring the dyestuff to the substrate to conduct the dyeing process. It overcomes the limitation of water resource issue as supercritical fluid carbon dioxide and other different types of organic solvent can be a substitute. It also overcomes limitation of existing system and high engineering requirement of the new system such that these waterless dyeing technologies can be widely adopted by the industry.
