Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, have announced the launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks.

Archroma introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its ADVANCED DENIM concept. By combining the oxidation and fixation steps, it can shorten the dyeing process and thus realize resource savings. The company has been working with its partners to improve the Pad-Ox process.

To achieve maximum positive impact, Archroma is using its Diresul range of low sulfide sulfur dyes and, more recently, its innovative plant-based range of EarthColors. A wide selection of dyes from these two ranges has received the Cradle-to-Cradle Product Innovation Institute’s Platinum Level Material Health Certification.

Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions for more than 25 years. In 2008, it developed G2 Dynamic, the first ozone treatment for continuous fabric that reduces the amount of water and chemicals used, while saving costs at the mill and eventually at the garment finishing facilities.

This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser. The machinery can be used along with Pad-Ox technology to help cleaning fabric and improve fastness results. While it allows process to work at room temperature.

Archroma and Jeanologia therefore decided to team up and combine their expertise in sustainable dyeing and finishing technologies. After several months of development, they have come up with a way to apply the Pad-Ox dyeing process at room temperature, whilst still improving fastness and allowing higher contrasts after wash-down.

A binder-free technology to obtain end articles that are softer and have greater color durability to repetitive washing and solidity against rubbing than other wash-out processes.

The new ‘Pad-Ox G2 Cold’ dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional benchmark fabric finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.

Maximum savings can be achieved by mills and garment manufacturers who wish to switch from a conventional dyeing process straight to ‘Pad-Ox G2 Cold’ to obtain high quality fabrics for comfortable and casual wear.

Manel Jimenez, Business Development Manager at Archroma’s Competence Center for Denim & Casual Wear, commented, “It was very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize results.”

For Jean Pierre Inchauspe, Business Director of G2 Dynamic at Jeanologia, “This association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment.”
