TENCEL™ is a trademarked brand of fibers produced by the Austrian company Lenzing AG. It includes both TENCEL™ Lyocell and TENCEL™ Modal, which are regenerated cellulose fibers made from sustainably sourced wood — primarily eucalyptus, beech, or spruce. What sets TENCEL™ apart is its closed-loop production process, which reuses over 99% of the water and solvents (like non-toxic NMMO) during manufacturing. The resulting fibers are biodegradable, soft, strong, and certified to meet high environmental standards.

TENCEL™ is widely used in fashion, bedding, and personal care textiles for its smooth texture, breathability, and moisture-wicking qualities. Lenzing’s supply chain transparency and sustainability certifications (including FSC® and OEKO-TEX®) make TENCEL™ one of the most trusted and eco-conscious branded fibers available in the market today.

Generic modal is produced from beechwood cellulose through a viscose-based regeneration process. While softer and more durable than traditional viscose, sustainability varies depending on sourcing and chemical management. Modal is commonly used in underwear, loungewear, and everyday garments where softness and shape retention are key.
