Fabric Dyeing with CO2 instead of water

Sustainability Aspects: The dyeing of fabrics and cloths is very waterpolluting. Using reclaimed and pressurized CO₂ as the dyeing medium in a closed loop process. Thanks to the high permeability of SC CO2, the dyes are transported easily and deeply into fibres, creating vibr


CO₂ dyeing does not need added process chemicals to dissolve dyes. This technology uses 100% pure dyes and with more than 98% uptake there is no waste.
No process chemicals, no water, no waste water and therefore no waste water treatment is necessary. The CO₂ used is reclaimed from existing industrial processes, recycling 95% of it in a closed loop system and on an industrial scale.

CO₂ dyeing is a dry process, eliminating the need to evaporate water which makes the technology very energy efficient. 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.
