What is Lyocell?

Lyocell is a biodegradable fiber made from sustainably managed eucalyptus trees.

Some highlights are below:


Derived from nature, all TENCEL™ standard Lyocell fiber types have been certified as biodegradable and compostable under industrial, home, soil and marine conditions, thus they can fully revert back to nature.

TENCEL™ Lyocell fibers are naturally soft to the touch and offer long-lasting
comfort. When viewed under an electron microscope, TENCEL™ Lyocell
fibers exhibit a smooth surface area, giving fabrics a soft feel and ensuring
comfort for sensitive skin.

TENCEL™ Lyocell fibers support body temperature regulating properties through their moisture management. Derived from natural material, the microscopic fibrils of cellulosic fibers are structured to regulate the absorption and release of moisture, contributing to fabric breathability that supports the body’s natural thermal regulation. The TENCEL™ Lyocell cellulose fibers have a higher vapor uptake than cotton.

TENCEL™ Lyocell fibers are derived from sustainable wood sources, harvested from certified and controlled sources following the stringent guidelines of the Lenzing Wood and Pulp Policy. These fibers are also available with FSC®(C041246) or PEFC™ certification upon request. Moreover, wood and pulp used by the Lenzing Group comes from natural forests and sustainably managed plantations. TENCEL™ Lyocell fibers have earned United States Department of Agriculture (USDA) BioPreferred® designation.

TENCEL™ Lyocell fibers have gained the reputation for their environmentally responsible, closed loop production process, which transforms wood pulp into cellulosic fibers with high resource efficiency and low ecological impact. This solvent-spinning process recycles process water and reuses the solvent at a recovery rate of more than 99%. This economically viable manufacturing process received the European Award for the Environment from the European Commission in the category “The Technology Award for Sustainable Development”. TENCEL™ Lyocell fibers have been certified as Bio-based by the U.S. Department of Agriculture (USDA). Moreover, all Lenzing fiber production sites operate according to a certified Environmental Management and Occupational Health and Safety system (ISO14001, OHSAS 18001).
