G-Star ramps up aniline-free collection
04/04/2024
In traditional denim production, the aniline remains bound with the indigo pigment on the fabric with the remaining aniline discharged during the dyeing and washing process, said the partners.
As a 30% pre-reduced indigo solution, Denisol Pure Indigo 30 makes it possible to produce indigo-dyed denim without aniline impurities throughout the process.
It also reduces chemical consumption while allowing high reproducibility and creating deep indigo shades, said Archroma.
Umberto De Vita, director for denim at Archroma Textile Effects, said. “If we remove aniline from the indigo dyes, we also remove it from the denim production process and its wastewater, and thus eliminate the risk of pollution. Denim that is free of aniline can also be more efficiently and sustainability recycled and reused, making circularity a more viable option.
“We are delighted to see trendsetters like G-Star ramping up aniline-free production.”
G-Star is working towards making 20% of its collection from Cradle to Cradle-certified fabrics by 2025. Denisol holds a Gold Level Material Health Certificate from the Cradle to Cradle Products Innovation Institute.
Amy Wang, managing director of Advance Denim, said: “We were the first mill in China to launch an aniline-free collection with Archroma and our new plant in the Nha Trang in Vietnam is a 100% aniline-free indigo factory.”
