Jeans and other denim garments
Blended with cotton, the traditional fiber for denim, TENCEL™ fibers can improve the properties of denim garments in various ways such as enhancing their breathability, adding softness for greater comfort, or extending their color retention.
TENCEL™ Lyocell fibers are highly versatile and distinguished by their greater strength among cellulose fibers. TENCEL™ Lyocell fibers in TENCEL™ Denim match the durability of cotton, so has a long-lasting quality.
TENCEL™ Lyocell fibers are naturally smooth to the touch, as evidenced by the TSA/Tissue Softness Analyzer test. When viewed under an electron microscope, TENCEL™ Lyocell fibers exhibit a sleek surface area, enabling fabrics to glide lightly over skin.
Through moisture management, TENCEL™ Lyocell and Modal fibers support the body’s natural thermal regulation. Derived from natural material, the microscopic fibrils of cellulosic fibers are structured to regulate the absorption and release of moisture, contributing to fabric breathability. TENCEL™ Lyocell and Modal cellulose fibers have a higher vapor uptake than cotton combined with their smooth fiber surface. This supports the body’s natural thermal regulating mechanism.
Exquisite softness derives from fine fibers, creating softer textiles. TENCEL™ Modal fibers exhibit a smooth surface and high flexibility, resulting in a naturally soft quality of the textile.
The softness of Modal fiber 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 TENCEL™ Modal fibers are twice as soft as cotton.
- The softness of TENCEL™ Modal fibers lasts longer and is able to withstand repeated wash and dry cycles compared to cotton. (Tested Fabric: Single jersey N/50/1, 120 g/m2, test method: Ring pull-through and TSA.)
- LENZING™ Modal Micro Air is Lenzing’s finest and lightest wood-based fiber.
- The degrees of softness of LENZING™ Modal, Modal Micro and Modal Micro Air can be measured by various handfeel assessment as well physical test methods such as the Tissue Softness Analyzer, Phabro-meter and Ring pull-through.
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.
TENCEL™ Modal fibers are mainly manufactured from beechwood, 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 or controlled sources following the stringent guidelines of the Lenzing Wood and Pulp Policy. These fibers are also FSC® (C041246) or PEFC™ certified.
Moreover, wood and pulp used by the Lenzing Group comes from natural forests and sustainably managed plantations. TENCEL™ Lyocell and Modal fibers have been certified as Biobased under the BioPreferred® Program of the U.S. Department of Agriculture, a governmental body.
TENCEL™ Lyocell fibers
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%. TENCEL™ Denim gives customers peace of mind knowing their products are eco-responsible and have a low carbon footprint.
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” (2002). TENCEL™ Lyocell fibers have earned United States Department of Agriculture (USDA) BioPreferred® designation. Moreover, all fiber production sites operate according to a certified Environmental Management and Occupational Health and Safety system.
TENCEL™ Modal fibers
Fully integrated pulp and fiber production at the Lenzing site in Austria makes it possible to produce TENCEL™ Modal fibers in an eco-responsible way. Lenzing is committed to being environmentally responsible throughout the production process, by optimizing the use of renewable energy from the pulp mill and recovering remaining components as co-products. Numerous Lenzing innovations have been integrated in the production of TENCEL™ Modal fibers to make the process environmentally sound.
(Eco Color technology)
Color pigments embedded in dope-dyed fiber retain long-lasting color vibrancy better than conventionally dyed fiber, and are less prone to fade even after repeated washing.
