New water-saving dyeing process for denim with Jeanologia


The launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks, has been announced by the producer of dyes and specialty chemicals Archroma Management LLC, Reinach/Switzerland, and the supplier of sustainable technologies for garment finishing, Jeanologia, Paterna/Spain.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.
Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions. Its G2 Dynamic was the first ozone treatment for continuous fabric that reduces the amount of water and chemicals used, thus saving costs further down the textile chain. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser.
In their joint project, the 2 companies have come up with a way to apply the Pad-Ox dyeing process at room temperature, whilst still improving fastnesses and allowing higher contrasts after washdown. 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 finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.
