DyeCat

Polymer Coloration

Polyesters used for apparel applications account for over 40% of world textile consumption and their use is increasing, consuming fossil fuel resources and adding to landfill sites. Polyester coloration is an environmentally unfriendly process, using large amounts of water and a cocktail of chemicals.

The DyeCat process is a significantly simpler process, which removes the wet processing coloration step altogether. Whereas dyeing currently occurs after the polymerisation step, involving numerous chemicals and gallons of water requiring treatment, the use of DyeCat technology in the process would result in pre-coloured polymer.

DyeCat aims to develop optimized additives for:

	Coloration of polymers for apparel, packaging, coatings etc. in both high value and commodity sectors
	Functional polymers e.g. intrinsic UV protection, IR applications e.g. security

We have a range of patented technology for the preparation of light absorbing polymeric materials (IR, visible, UV).

Variety of approaches allows flexibility in:

Example of a drawn
DyeCat-colored PLA
polymer fibre

		Polymer composition
		Polymer molecular weights and polydispersities
		Coloration strength
		Range of light absorbing chromophores

Superior coloration technology:

		Homogeneous colorant throughout cross section of polymer
		Increased wash and light fastness

Greatly improved preparative method:

		Significant cost reductions on comparable conventional technology
		Reduced environmental impact

The technology is particularly applicable to sustainable, biodegradable polymers such as PLA and PHB.
