As brands and supply chain partners seek greater sustainability, the demand for eco-responsible alternatives in denim industry is growing rapidly. 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.

According to the UN, approximately 2,000 gallons of water go into making one pair of jeans. It’s no secret that the conventional dyeing and washing process is one of the most harmful contributors during the production of denim garments.

Recognising the need to reduce the ecological footprint of denim, Lenzing introduced TENCEL™ Modal fibre with Indigo Color technology which delivers superior colour fastness with substantial water, chemical and electricity savings, with less wastewater produced and no heat energy used. 

“Lenzing has continually innovated new technologies to support brand partners in enhancing sustainability, and given the conscious shift toward eco-friendly denim, we saw this as an opportunity to create a new system that could offer an eco-responsible alternative to denim production,” Tricia Carey, Director of Global Business Development for Denim at Lenzing,told Apparel Resources (AR) in an exclusive interview.

“Our Indigo Color technology was born to combat concerning impacts that conventional denim production practices have on our planet, as well as complement our existing sustainable TENCEL™ branded modal fibres to further reduce the ecological footprint of denim fabrics and garments.While Lenzing is already producing spun dyed fibresin our portfolio, so we considered indigo pigment as an option too,” she added.

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).

“Innovation is at the core of what we do, from sustainable fibre sourcing through industry leading features and production processes, with the ever-present goal of safeguarding our environment,” Florian Heubrandner, Vice President Global Textiles Business at Lenzing AG told AR. “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.”

TENCEL™ Modal fibres with Indigo Color technology are inherently versatile and enable implementation in a range of multi-fibre blends. Compared to water and energy-intensive conventional indigo dyeing, this technology provides indigo coloration with substantial water, chemical and electricity savings, along with less wastewater produced, and no heat energy used. In addition to the above, 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.

“This specially commissioned indigo pigment is based on more than a decade of our working experiences on Indigo Synthesis in Germany. Twenty-five years ago, we invented the most eco awarded DyStar® Indigo Vat 40 per cent to meet the demand for sustainable manufacturing and production,” Günther Widler, Head of Technology, Denim of DyStar®said.

How TENCEL™ Modalfibre with Indigo Color technology is superior to conventional denim dyeing processes

The Indigo Color technology is a one-step spun dyeing process that incorporates indigo pigment into TENCEL™ Modal fibres and has a smaller carbon footprint.Based onLenzing’s testing,while comparing this innovation to conventional powder indigo dyeing and pre-reduced liquid indigo dyeing, the resource savings are significant with:

  • Water savings: 99%
  • Chemical savings: 80%
  • Electricity savings: 99%
  • Wastewater savings: 99%
  • Heat energy savings: 100%

In general, the higher the percentage of TENCEL™ Modal fibres with Indigo Color technology used in the fabric, the greater the potential savingsover traditional range rope dyed indigo yarns.

Lenzing gets into new partnerships

To make the commercial launch of TENCEL™ Modal with Indigo Color technology possible, Lenzing partnered with Adriano Goldschmied, widely regarded as the ‘Godfather of Denim’, along with leading supply chain partners including denim mills such as Candianiand Cone Denim.

Commenting on the collaboration, Alberto Candiani, Global Manager of Candiani, said, “With driving sustainability at our core, we look forward to a fruitful collaboration with the production of this eco-responsible fibre type. TENCEL™ Modal with Indigo Color technology also represents a great product to expand denim’s performances and aesthetics around sustainability itself.”

Titled the ‘Seed of Joy’, the concept capsule collection features woven, circular and sweater knit fabrics made using the TENCEL™ Modal with Indigo Color technology, in partnership with mills such as Blue Diamond and In The Loop, as well as machinery producer Shima Seiki.

Commenting on the collaboration, Tricia said, “Since I started working for the TENCEL™ brand in 1998, Adriano has always been interested in our TENCEL™ branded fibres.  For the past 10 years, Adriano has been one of the leading advocates for the denim industry to lower their environmental impact.  So, it was a natural process that we work together on this new denim innovation. It was a great privilege to work with such a legendary designer, his longstanding push for sustainability coupled with his industry experience made the collaboration a truly productive and insightful experience.”

Future denim trends

The denim product is a staple for many people, and as the industry continues to develop different denim designs, cuts and uses,Lenzingis keen to continue to be at the industry forefront to provide the ability to sustainably produce eco-fibres for the denim industry.

On this front, Lenzinghas been actively partnering with different designers, brands, influencers and industry tastemakers to achieve the above.

Currently the denim industry is working hand-in-hand with supply chain stakeholders to tackle all the major apparel industry challenges to reduce the environmental impact, as well as address consumer need for greater comfort apparel with joggers and looser fits.  

“The use of our new fibres has no design limitations and adds the additional comfort of sustainable consumption for our designers and consumers. Denim is tackling all the major apparel industry challenges to reduce the environmental impact and at the same time, is addressing the need for comfort apparel with joggers and looser fits,” Tricia explained.
