New Cotton Dyeing Process Claims Zero Toxic Discharge
August 13, 2012
New York City-based ColorZen launched a new technology to reduce the environmental impact of dyeing cotton.
By pre-treating the cotton, ColorZen says it creates a strong affinity between the dye and the cotton fiber, eliminating the need for harsh chemicals and reducing water and energy consumption.
ColorZen claims the process achieves zero toxic discharge by eliminating the use of toxic chemicals that are often flushed back into fresh waterways and rivers. Additionally, the technology reduces water consumption by 90 percent and can dye the same amount of cotton three times faster than conventional dyeing techniques.
The process is designed to be compatible with any existing equipment used for dyeing, so manufacturers and dye houses will not need to make new capital investments or change dyestuffs.
Oeko-Tex Standard 100, a global certification for textiles, issued its seal of approval to ColorZen LLC, stating that its technology is 100 percent free of harmful substances and safe for use on products for babies through adults.
ColorZen is making its technology available to retailers and brands for upcoming spring and summer lines.
Just last week, sportswear company Adidas unveiled its own process for dying fabric without water. The process, developed with Thailand’s Yeh Group, uses CO2 instead of water.
Adidas, Puma and Nike have all pledged to reduce to zero the discharge of hazardous chemicals throughout their entire supply chains and across the entire lifecycle of its products by 2020.
