HeiQ’s DYEFAST offers lower carbon dioxide emissions

May 7th, 2015 / By: / What's New?

Swiss textile producer HeiQ has developed a polyester-dyeing technology that it says will lead to less energy and water consumption, lower costs, and a reduced carbon footprint. The process, named DYEFAST, will be introduced at Techtextil Frankfurt.

HeiQ says the new technology will cut dyeing time by a third, leading to a lower environmental footprint. If used throughout the global polyester dyeing industry, potentially 50 million metric tons of CO2 emissions a year could be saved, the company says.

The dyeing process, reaching temperatures up to 130 degrees Celsius, strongly affects the environment, including high water and energy consumption, wastewater burden and up to 4kg CO2 emission per kilogram of textile produced. DYEFAST contributes to improving the productivity by 33 percent for dye house processing using existing equipment, the company says.

The technology also aims to provide improved dyeing quality without having to change dye recipes. The system provides enhanced color leveling and reduced risk of spotting, potentially prolonging the useful life of textiles.
