Indigo Color technology

Lenzing brings you a new tradition in indigo

A one-step spun-dyeing process incorporates indigo pigment into TENCEL™ Modal fibers. This new product delivers long-lasting indigo color with greater convenience and multiple environmental benefits. Take a look at the advantages of this process compared with conventional indigo dyeing.

As compared with conventional indigo dyeing, TENCEL™ Modal with Indigo Color technology leads to significant savings in water (>99%), chemicals (>80%), electricity (>99%), wastewater (>99%) and heat energy (100%)*:


In general, the higher the percentage of TENCEL™ Modal with Indigo Color technology used in the fabric, the greater the potential savings. Lenzing’s results are based on tests using 100% LENZING™ Modal Color Indigo fibers. Customers are recommended to perform their own calculations based on their individual variables and are responsible for the accuracy of the results.

key benefits

0004 Botanic Origin

botanic origin

TENCEL™ Modal fibers are mainly manufactured from beech wood, sourced from sustainable forests in Austria and neighboring countries. Beech wood forests are a natural and renewable source of raw material. A big share of the wood used at the Lenzing site comes from Austria, harvested from certified and controlled sources following the stringent guidelines of the Lenzing Wood and Pulp Policy.

Moreover, wood and pulp used by the Lenzing Group comes from sustainably managed forests. TENCEL™ Modal fibers have earned United States Department of Agriculture (USDA) BioPreferred® designation.

0014 Sustainable Production

sustainable production

Fully integrated pulp and fiber production at the Lenzing site in Austria makes it possible to produce fibers in an eco-responsible way. At Lenzing, we strive to safeguard resources for future generations by the use of renewable energy from the pulp mill and by recovery of remaining components as co-products. Numerous Lenzing innovations have been integrated in the production of TENCEL™ Modal fibers, to make the process environmentally sound.

0006 Enhanced Breathability

contributes to breathability (TENCEL™ Modal fibers)

TENCEL™ Modal fibers support body temperature regulating properties through their moisture management. Derived from natural material, the sub-structure of modal is structured to regulate the absorption and release of moisture, contributing to fabric breathability that supports the body’s natural thermal regulation.

Tencel Certified Safe

certified safe

The STANDARD 100 by OEKO-TEX® certification confirms that TENCEL™ Modal fibers have been tested for numerous regulated and non-regulated harmful substances and are therefore harmless for human health.

Tencel  Rubbing Fastness

rubbing fastness

As compared with conventionally dyed indigo fibers, color retention of TENCEL™ Modal fibers with Indigo Color technology is superior through dry and wet crocking and rubbing. The color is less prone to fade even after repeated abrasion in everyday wear, and color is not transferred to other surfaces even when garments are wet.

Tencel  Commercial Laundry Color Adjustment

commercial laundry color adjustment

Despite the resistance to home-laundry fading of LENZING™ Modal Color Indigo fibers, wash-down effects can be achieved using commercial denim laundry techniques.
