Somelos, an integrated textile firm, and Archroma, a pioneer in speciality chemicals for sustainable solutions, have created a water-saving dyeing and finishing method that produces no wastewater in order to promote sustainable cotton processing.
A New Dry Dyeing/Ox Finishing procedure developed by Archroma and Somelos is utilised to make cotton fabrics for shirts and bottoms. Utilising technologies for washdown effects like ozone and laser treatments, as well as Archroma’s Pad-Ox dyeing process, which combines oxidation and fixation into a single step, this cutting-edge method achieves water savings of up to 97 per cent when compared to traditional cotton dyeing and finishing methods.
Water is only used in the New Dry Dyeing/Ox Finishing process to prepare dye and oxidation baths. Pre-washing is not necessary with Archroma’s Diresul RDT liquid pre-reduced sulphur dyes since they allow for simple washdown and direct fixing. Shorter processing times, cleaner manufacturing, and great wash-fastness are the results of this.
The textile effects section at Archroma’s director of the denim market segment, Umberto De Vita, underscored the companies’ shared commitment to advancing sustainability in the textile and clothing sector.
He said, “Together, we have developed a water-saving dyeing and finishing process that not only represents a significant advance in sustainability for the textile industry, but that also empowers brands to protect the environment and deliver eco-friendlier products to an eager buying public.”
Sofia Vale, R&D manager at Somelos, added: We are delighted to be working with Archroma as we take another step on our sustainability journey and prioritise water saving with our new and innovative cotton dyeing and finishing process.”
