Archroma, Jeanologia team on water-saving dyeing process

By Beth Wright

Textile chemicals specialist Archroma has partnered with denim finishing technology specialist Jeanologia to launch a new water-saving dyeing process at room temperature for denim and casual wear.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its Advanced Denim concept. The idea was fairly simple, yet technically revolutionary at the time. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realise substantial resource savings in water, wastewater, cotton waste, and energy.

Over the years the company has worked with its textile manufacturers and partners to improve the Pad-Ox process, in particular woven applications such as chinos and casual wear. It has now partnered with Jeanologia, utilising the firm’s G2 Dynamic ozone treatment, to improve the focus further, particularly in the areas of temperature and fastness.

G2 Dynamic makes fabric more stable and consistent and better prepares it for other technologies like laser. The machinery can be used along with Pad-Ox technology to help cleaning fabric and improve fastness results, while allowing the process to work at room temperature.

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, the firms say.

“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, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality,” says Jean Pierre Inchauspe, business director of G2 Dynamic at Jeanologia.
