DyeCoo Textile Systems

DyeCoo Textile Systems, established in March 2008, operates as a pivotal force in sustainable textile manufacturing. The company originated as a spin-off from FeyeCon, a research organization exploring CO2 applications, following foundational research at the University of Delft in the Netherlands. Among its founders are Reinier Mommaal and Ernst Siewers, with Geert Woerlee also credited for his foundational role based on over two decades of R&D in the field. Mommaal's 12-year background in sustainable textile production directly influenced the company's trajectory.

The firm's core business is the development and supply of industrial equipment for a water-free and process chemical-free dyeing solution. Its business model centers on selling its large-scale DyeOx machines directly to textile manufacturers, primarily in Asia, with a strategic focus on Taiwan, Vietnam, and Thailand. This B2B approach involves partnerships and collaborations, with revenue generated through the sale of these systems, which cost approximately €2.5 million each. While the initial capital investment is higher than traditional machinery, the long-term operational costs are lower due to the elimination of water treatment plants and reduced energy consumption. DyeCoo has attracted significant investments from entities like IKEA GreenTech, Nike's venture arm, Ingka, and the Otto Group, facilitating its expansion.

DyeCoo’s patented technology employs supercritical carbon dioxide (scCO2) as a solvent to dye textiles, completely sidestepping the use of water. The process involves pressurizing reclaimed CO2 until it reaches a supercritical state, a phase between liquid and gas, where it develops a high solvent power. This scCO2 dissolves pure, powdered dyes and transports them deep into the fabric's fibers, particularly effective for polyester and its recycled variants. The system operates in a closed loop, recycling over 95% of the CO2 for subsequent batches. This method results in a dye uptake of over 98%, creates vibrant colors, and leaves the fabric completely dry. Key benefits include zero wastewater discharge, significantly reduced energy usage, and shorter batch cycles, which collectively lower operating costs and provide geographical freedom from water sources. The technology has been adopted by major brands like Adidas, Nike, and IKEA, and its machines are manufactured in the Netherlands.
