Waterless Textile Dyeing


Sustainability Issue: 

Category: Water

The textile dyeing industry is one of the largest consumers and polluters of water:

  • Water use: The amount of water needed in the dyeing process and the scale of industry put pressure on the availability of clean water in developing nations. Traditional fabric dyeing methods use an estimated 30 liters of water to dye a single t-shirt.
  • Water pollution: Dyes and process chemicals are used inefficiently resulting in large amounts of waste and wastewater that is released often untreated into bodies of water. Between 17 and 20% of water pollution from industrial sources is produced by the textile dyeing process.

Technology Solution:

  • DyeCoo is waterless dyeing technology that uses reclaimed CO2, a waste product, to dye textiles in a closed loop system. The system uses pressure to bring CO2 to a supercritical state where it acts as a highly effective solvent, allowing dye to dissolve and permeate deep within textile fibers. The CO2 used in the system is reused with a 95% efficiency.
  • The DyeCoo technology eliminates the need for water, reduces the amount of dyestuff needed by 50%, and does not require any additional dyeing or process chemicals. This technology eliminates the waste and wastewater produced in traditional textile dyeing.
  • This process of textile dyeing reduces energy usage and operational costs. It is estimated DyeCoo can result in a cost savings of 40-60% for companies.
  • Nike has utilized DyeCoo’s technology to create a collection of polo shirts under the brand of “ColorDry”.


  • Clothing manufacturers
  • Clothing companies
  • Textile dyers
  • Textile manufacturers
  • Dyestuff suppliers


  • In conjunction with dyestuff suppliers, develop dyestuffs that are compatible with DyeCoo machines and all all fabric types
  • Increase the commercial availability of the DyeCoo machines
  • Implement a maintenance and service structure allowing for the correct set up and longterm use of machines around the world

One thought on “Waterless Textile Dyeing

  1. This technology would also reduce the cost of construction of a facility that dyes clothing using this technology (dependent on initial pricing) while reducing construction time as well. A traditional dyeing facility would need extensive water supply and waste ejection plumbing infrastructure that needs to be maintained and inspected.
