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.

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.

All standard TENCEL™ Modal fiber types have been certified as biodegradable and compostable under industrial, home, soil, fresh water and marine conditions, thus they can fully revert back to nature.

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.

The ability to absorb moisture makes TENCEL™ Modal fibers tension-free with lower electrostatic charging. In comparison with synthetics, there is an absence of electrostatic charge under normal atmospheric conditions.

Color pigments embedded in spun-dyed LENZING™ Modal Color fiber retain long-lasting color vibrancy better than conventionally dyed fiber, and are less prone to fade even after repeated washing.

TENCEL™ Modal fibers exhibit a smooth surface and high flexibility, resulting in a naturally soft quality of the textile. The softness of TENCEL™ Modal fibers is confirmed by a variety of physical test methods, including Kawabata, TSA, Handle-o-meter, and Phabro-meter:

- Measurements and hand evaluations of softness show that fabrics made with TENCEL™ Modal fibers are twice as soft as cotton fabrics.

- The softness of TENCEL™ Modal fibers lasts longer and is able to withstand repeated wash and dry cycles compared to cotton.

- LENZING™ Modal Micro Air fibers are Lenzing’s finest and lightest wood-based fiber.

- The degrees of softness of LENZING™ Modal, LENZING™ Modal Micro and LENZING™ Modal Micro Air can be measured by handfeel assessment as well as various physical test methods such as the Tissue Softness Analyzer, Phabro-meter and Ring pull-through.
