DyeCoo uses patented and industry-proven technology based on CO2, instead of water.
The technology uses reclaimed CO₂ as the dyeing medium in a closed-loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily. Thanks to the high permeability, the dyes are transported easily and deeply into fibers, creating vibrant colors.
CO₂ dyeing does not need added process chemicals to dissolve dyes. Our technology uses 100% pure dyes and with more than 98% uptake, we don’t waste any of it.
No process chemicals, no water, no wastewater and therefore no wastewater treatment is necessary. The CO₂ we use is reclaimed from existing industrial processes, recycling 95% of it in a closed loop system.
We can proudly say that we deliver great results on an industrial scale, which is not to be taken for granted when implementing a completely new technology. In fact, DyeCoo is the only company that has been able to scale up CO₂-based textile processing technology to a proven industrial scale, winning industrial and commercial endorsements from both textile mills and end-users.
CO₂ dyeing is a dry process, eliminating the need to evaporate water. The addition of efficient colour absorption and short batch cycles makes our technology very energy efficient.
Short batch cycles, efficient dye use, no waste water treatment all contribute to significantly reduced operating costs.
We use 100% pure dyestuff giving beautiful, vibrant colours. The dye is distributed evenly over the fabric and the technology allows for easy colour correction. The dyestuff penetrates deep into the fibres creating intense colours with excellent quality characteristics.
Dyeing without water equals geographical freedom, becoming completely independent from clean water availability. We can dye fabric in the middle of the Sahara. This opens up new opportunities for the textile industry, allowing production to occur closer to market, shorten lead times and disconnect from Earth’s most valuable resource … water.
