LENZING – Apparel brands can now use spun dyed indigo modal fibres in their knit and woven denim collections to improve their environmental footprint, thanks to a new development from Lenzing that claims to use fewer natural resources, and provides superior colour fastness compared to traditionally dyed denim.
Developed in partnership with Adriano Goldschmied, founder of House of Gold, the denim mills Candiani and Cone Denim, as well as pigment supplier DyStar, the one-step spun-dyed indigo process gives savings in water and energy consumption and also reduces denim’s impact on wastewater.
Florian Heubrandner, vice president global textiles business at Lenzing, said: “Tencel Modal with indigo technology sets a new benchmark for indigo application and sustainability in the denim industry.”
In this story, we take a technical look at how this could play out in denim mills and what’s new about the technology.
