Why we choose TENCEL™ Lyocell fibers
From forest to fiber. TENCEL™ Lyocell fibers are soft and smooth to touch. They have high tenacity among cellulosic fibers, support a natural dry feeling through moisture control and enable a subtle sheen in fabrics. In addition to these performance benefits, TENCEL™ Lyocell fibers have a lower environmental impact and are made using a closed loop production process which recovers 99.8% of solvent.
