Huntsman International | AVITERA Reactive Dyes for Cotton
“Major potential for environmental impact”
One judge assessed AVITERA dyes as being “an innovative approach with wide potential for impact if scaled over printed fabric production worldwide; major potential for environmental impact.”
Huntsman International, a global manufacturer and marketer of differentiated chemicals, has pioneered innovations in the industry for 40 years. Its most recent dye system is getting rave reviews. Developed with the express purpose of reducing the amount of water and energy required to dye cotton, the AVITERA dye system is economically comparable to conventional dye systems when considering time, energy required (dyeing temperature), dye costs, and water consumption, providing an economically sustainable alternative while also considering an environmental improvement compared to present technology. Making a full color palette of dyes available, Huntsman International developed this new chemistry with the focus on environmental sustainability, and especially to address a more sustainable approach to water use.
AVITERA dyes use tri-functional reactivity that provides a high reaction and fixation rate with cellulosic fiber, leaving very little unfixed dye to be removed, dramatically reducing water waste. Dye that is not reacted is easily removed at low temperatures because the dyes have low intrinsic affinity for the fiber. When using these dyes, up to 50% less water is required, up to 70% less energy is required, and up to 50% less time is used in the dye process.
The judges agreed that this process, already being used in many industries worldwide, was worth expanding. As one judge stated, “The AVITERA dyes were engineered for sustainability and provide a clear economic and sustainable value proposition, particularly in markets facing water constraints but that are also highly dependent on industries that utilize cotton.”
