Archroma and CleanKore partner to promote sustainable indigo dyeing

Company News, News | February 3, 2021 | By:

Archroma, a global leader in specialty chemicals towards sustainable solutions, has announced a strategic partnership with technology innovator CleanKore, aiming to advance sustainable dyeing processes throughout the denim supply chain.

The agreement will allow Archroma and CleanKore to promote the benefits of each other’s technologies.

This includes Archroma’s robust catalog of dyes and specialty chemicals along with CleanKore’s patented process of dyeing yarns at the denim mill that completely eliminates the need for potassium permanganate (PP) spray and laser booster to achieve the bright white abrasion effect in the garment finishing process.

The result is a large and circular bright white core with a small ring of indigo dye. The technology eliminates the chemicals associated in the PP spray and laser process and also saves significant amounts of water and energy throughout the manufacturing process from fabric to garmenting.

No new equipment or capital expenses are needed to implement the CleanKore technology, which works on all denim fabric, including dark indigo, sulfur top/bottom and sulfur black.

Archroma’s global technical team of denim coloration specialists will provide support to denim mills seeking to implement the CleanKore technology and develop the desired looks and effects with the right colors and chemical systems for their production set-up.

CleanKore estimates that the technology saves up to 15 liters of water per garment, or the equivalent of the drinking needs of five people per day, and up to 0.51 kWh of energy per garment, or the equivalent of five 100-watt light bulbs on for one hour. The CleanKore technology also leads to a 10% to 20% increase in production throughput, as a result of a faster garment wash-down and the elimination of PP spray.
