Sportswear giant Nike has finally released the first consumer product produced using ColorDry water-free dyeing fabric. ColorDry was developed by DyeCoo Textie Systems in the Netherlands, and they have been working hard for more than ten years. This technology is not only beneficial to Nike or any brand, the impact DyeCoo technology has on the market makes all our hard work worthwhile. We think this is about reducing the use of water and chemicals in textile printing and dyeing, and Nike is one of the company’s investors. DyeCoo uses recycled carbon dioxide to replace water, saving 30 liters of water for each dyed T-shirt. This technology not only benefits the environment, it also ensures color saturation during the fabric dyeing process, saves energy and avoids added chemicals.
“Creating this technology that changes the rules of traditional dyeing is a long process, and it is an important step towards revolution in our industry. This product line proves that our technology is economically feasible, suitable for large-scale production, and can significantly reduce environmental impact. Impact,” said Mates Blacker, CEO of DyeCoo.
Nike’s new product line also includes the use of Nike’s Dri-FIT technology, which uses knitted fabrics to wick sweat away from the body. The polo shirt is also made from 100% recycled polyester, adding to its sustainable nature. ColorDry polo shirts will be available in six different colors.
According to media reports, ColorDry fabrics have started production in a new waterless dyeing and finishing factory in Taiwan last year (2013). The factory was established by a Taiwanese company.
Currently, it is estimated that 100-150 liters of water are needed to process 1 kg of textiles. Industry insiders have analyzed and calculated that before 2015, more than 39 million tons of polyester fiber needed to be dyed every year. This new technology has a lot of room for application and can restructure the printing and dyeing industry.
Nike is one of several companies taking part in the Detox Challenge, a movement launched two years ago by environmental pressure group Greenpeace that aims to achieve zero emissions of harmful chemicals from its supply chain by 2020.
The detox campaign proposes steps to achieve this goal and one of the issues in the joint “road map” is to address the issue of large amounts of water used in processes such as dyeing/finishing – a problem where wastewater treatment varies greatly between different plants. .
Nike said it expects DyeCoo’s supercritical liquid carbon dioxide, or “SCF” carbon dioxide dyeing technology, to have a particularly positive impact on the textile printing and dyeing industry in Asia and will also expand to the world’s textile industry. As this technology becomes increasingly large-scale, a large amount of water for traditional textile printing and dyeing will no longer exist, and there is no need to use fossil fuels to heat large amounts of water.
Water is removed from the textile dyeing process, also eliminating the risk of effluent discharge and environmental harm. The carbon dioxide used in DyeCoo’s dyeing process will also be recovered and reused.
Waterless dyeing technology is currently limited to polyester fabrics, but new research is underway to expand its applicability to other natural and synthetic fabrics.
