Archroma a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, , a world leader in sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.

The production of denim requires a succession of several steps aimed at imparting the qualities we love in our favorite pair of jeans.

The breakthrough alternative to the fabric cleaning concept presented by Jeanologia and Archroma combines the use of the aniline-free Pure Indigo Icon dyeing system of Archroma, and the water-free** and chemical-free “G2 Dynamic“ finishing technology of Jeanologia.

The Archroma Pure Indigo Icon is based on an innovation launched by the company in May 2018: its aniline-free* Denisol® Pure Indigo. Aniline is a key ingredient to make the indigo molecule. Unfortunately, during this process some aniline impurities are carried through into the indigo dyestuff. When the indigo is dyed on the fabric, a lot of the aniline impurity is locked into the pigment in the fabric. The remainder of the aniline impurity, approximately 300 metric tons annually, 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. The new Denisol® Pure Indigo 30 liq was therefore developed as an aniline-free(1) indigo solution for designers, manufacturers and brand owners who long for authentic indigo inspiration.

The Archroma/Jeanologia solution can also be used with additional Archroma coloration systems such as Indigo Reflection or Pure Undertones.
