The Fiber and Biopolymer Research Institute, a division of Texas Tech University’s department of plant and soil science, today revealed a new foam-dyeing process for denim at a special event. Heritage denim brands Wrangler and Lee, as well as the Wal-Mart Foundation, are early investors in the technology and were in attendance at the event hosted by Indigo Mill Designs to show support for the initiative.

Foam-dyeing is a cost-effective and environmentally friendly process for dyeing yarns, but its use was limited for denim manufacturing. The indigo dye that creates denim’s blue color reacted to oxygen in the air and rendered the process ineffective — but Indigo Mill Designs’s Indigo Zero solution maintains oxygen-free conditions throughout the dyeing process until yarns are ready for “oxygen environments,” namely open-air or oxidation chambers. And the process “reduces chemical usage while achieving the same or better dye quality compared to conventional processes” in addition to “[resulting] in net reductions of water and energy usage of more than 90 percent.”
