During the Olympics, sportswear giants Adidas and Nike made simultaneous announcements of a new dyeing process that uses carbon dioxide instead of water. Though few noted it at the time, this development is a very big deal.
It is estimated that the dyeing of polyester clothing uses 2.4 trillion gallons of water every year, much of it in Asia, where water is becoming an ever more scarce commodity. By turning to CO2 instead, the companies aren’t just garnering a green badge, but gaining a long-term strategic advantage.
But how do you dye a shirt with CO2, which most of us think of as a gas? Read all about the new technology.
