Water-Saving Breakthrough: Woolmark Transforms Wool Dyeing with QuantumColour
Brussel, vrijdag, 20 juni 2025.
Woolmark has developed a groundbreaking dyeing method with Colourizd that uses only 0.5 litres of water per kilogram of yarn, compared to 60-120 litres in traditional processes. The QuantumColour procedure eliminates chemical pre-treatments and avoids wastewater production by directly injecting pigments into yarn fibres. Tested on 100% Merino wool and blended yarns, the technology offers a wide colour palette from faded to saturated. This innovation promises not only significant environmental benefits - using just 1% of water compared to conventional methods - but also opens new perspectives for wool producers by rendering wastewater treatment infrastructure unnecessary.
Revolutionary Water-Saving Technology
Woolmark has collaborated with Colourizd to develop an innovative dyeing method that radically transforms traditional wool production. The QuantumColour procedure uses only 0.833 percent of the water consumed by conventional methods, specifically 0.5 litres of water per kilogram of yarn compared to 60-120 litres in traditional processes [1][2][3].
Technical Innovation
The technology works by directly injecting pigments into yarn fibres, eliminating chemical pre-treatments and wastewater production [1]. The procedure has been successfully tested on 100% Merino wool and various blended yarns, including cotton, Tencel, and nylon [2].
Industrial Implications
Julie Davies, General Manager of Processing Innovation at Woolmark, emphasises that the technology provides suppliers with the ability to dye yarns without extensive wastewater treatment infrastructure [3]. The procedure delivers a broad colour palette, ranging from faded to saturated shades [4].
