AHMEDABAD – Retail giant H&M has partnered with its long-standing denim supplier Arvind Limited and Indian start-up Deven Supercriticals to explore the feasibility of supercritical CO2 dyeing of natural fibres, a technique that has previously been limited to synthetic fabrics.
With the prototype showing a reduction in energy, water, and chemical use, H&M said it is planning to test Deven’s new Suprauno technology at Arvind to use it as a more sustainable means of denim production.
