Innovation: Indigo Color Technology

Blue jeans, not blue rivers

Lenzing AG has developed a new resource-friendly technology to dye denim. The Indigo Color technology directly incorporates colour pigments into fibres and therefore hinders the release of toxic chemicals.

March 2021

From 6,000 to 10,000 litres of water are required to make one pair of jeans. But using Lenzing AG's Indigo Color technology, denim can now be dyed using far fewer resources. The Austrian fibre manufacturer has long worked on the sustainable optimisation of textile production processes and is regarded as an industry pioneer. Indigo Color technology introduces the blue pigments directly into TENCEL™ branded modal fibres using a one step spun-dyeing process that uses less water and energy. "By upending traditional manufacturing processes and implementing our pioneering technology along with renewable and eco-responsible materials, TENCEL™ Modal with Indigo Color technology sets a new benchmark for indigo application and sustainability in the denim industry,” says Florian Heubrandner, Vice President Global Textiles Business, Lenzing AG.

Until now, chemicals were added to the indigo pigment to dye denim.  The new process does without these and therefore supports not only water protection, but also health.  According to a report by the World Health Organisation (WHO) 20,000 deaths per year are caused by the adverse effects of chemicals used in textile production. With the new technology, Lenzing aims to create an alternative to environmentally harmful denim production. Fabrics derived from wood: The new product is sourced from sustainably managed Austrian beech forests. According to Lenzing, the TENCEL™ Modal fibre with Indigo Color technology has another advantage: The colour retention is greater and the fibre itself more versatile by nature, which enables its use in a range of multi-fibre blends.

The latest industry developments will be showcased at the upcoming edition of the leading international trade shows Techtextil and Texprocess, held from 21–24 June 2022 in Frankfurt am Main. New approaches were also discussed at the previous edition under the taglines Sustainability at Techtextil and Sustainability at Texprocess.  The exhibitors included Lenzing AG, presenting innovations focused on efficiency, the circular economy and eco-sustainability in textile production.
