The Lenzing Group is enhancing sustainable offerings for the denim industry with its TENCEL branded modal fibers with Indigo Color technology. The pioneering technology incorporates indigo pigment directly into TENCEL branded modal fibers using a one-step spun-dyeing process.

It delivers good color fastness relative to conventional indigo dyeing whilst using substantially fewer resources. This innovative offering is awarded with the EU Ecolabel, a label of environmental excellence awarded to products meeting high environmental standards throughout their life cycle.

The denim industry’s demand for eco-responsible alternatives is growing rapidly, as brands and supply chain partners seek greater sustainability. Lenzing has been working closely with such partners to counteract environmentally harmful denim production processes via the botanic origin of its raw materials and responsible production processes.

Denim remains an important market for Lenzing, and the introduction of TENCEL Modal with Indigo Color technology is designed to help reduce the ecological footprint of denim fabrics and garments. Produced in Austria, predominantly from beech wood derived from sustainably managed wood sources, this new offering has been designated BioPreferred by the United States Department of Agriculture (USDA).

“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,” said Florian Heubrandner, Vice President Global Textiles Business at Lenzing AG.

Among early launch collaborators for TENCEL Modal with Indigo Color technology is Adriano Goldschmied, founder of House of Gold, who is widely regarded as the “Godfather of Denim” for his progressive vision in denim development.

Indigo Color technology builds upon the credentials of TENCEL Modal fibers with new benefits. Compared to conventional indigo dyeing, the color retention of TENCEL Modal with Indigo Color technology is superior through dry and wet crocking and rubbing.

Despite resistance to home-laundry fading, wash-down effects for denim products can be achieved using commercial laundry techniques. TENCEL Modal fibers with Indigo Color technology are versatile and enable implementation in a range of multi-fiber blends.

Compared to water and energy intensive conventional indigo dyeing, this technology provides indigo coloration with large water, chemical and electricity savings, along with less wastewater produced, and no heat energy used.

Besides, a specially commissioned indigo pigment from dyestuff manufacturer DyStar, ensures that TENCEL Modal with Indigo Color technology can be certified with STANDARD 100 by OEKO-TEX, guaranteeing ultra-low levels of aniline.

In addition, to make the commercial launch of TENCEL Modal with Indigo Color technology possible, Lenzing has partnered with leading supply chain partners including denim mills - Candiani and Cone Denim.
