REINACH – Advance Denim Co will become the first Chinese denim manufacturer to offer a collection made with Archroma’s aniline-free Denisol Pure Indigo. Denisol Pure Indigo was launched last year by the Swiss-based textile chemical specialist amid concerns over the fact that aniline – a potentially hazardous indigo precursor molecule – could be the subject of increased legislative restrictions moving forwards. The new Denisol Pure Indigo was therefore developed as an aniline-free indigo solution for designers, manufacturers and brand owners.

During traditional indigo dyeing process production, some of the aniline stays locked into the indigo pigment and is difficult to wash off the fabric. The remainder of the aniline impurity is discharged during dyeing. This can be an issue as aniline is toxic to aquatic life. In addition, exposure levels to factory workers can be high. As a result of its toxicity it is now starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers.
Established in 1987, Advance Denim is the oldest denim mill in China. The company has its own innovative research and development, manufacturing and sales teams, including a 120,000 square meter manufacturing facility in Shunde, China, and well as offices in Hong Kong, Shanghai, Amsterdam and New York.
Umberto De Vita, global business development, denim & casual wear, at Archroma, said: “At Archroma, we try to do our part, step by step, and that is why we developed the purest pre-reduced liquid aniline-free indigo available on the market. Together with the most eco-conscious denim mills out there, such as Advance Denim in China, we can make clean indigo – and clean denim. Because it’s our nature!”
“Advance Denim and Archroma are demonstrating, through action, how a traditional industry can transform and become sustainable while remaining profitable,” added Amy Wang, managing director, Advance Denim.
