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.

Tencel Indigo Color Infographic 20210113

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.

*These numbers were calculated in tests conducted by Lenzing. Actual resource savings will vary depending on specific operating parameters.
