Tencel is a regenerated cellulose fiber made from natural wood pulp. Its core material is derived from wood sourced from sustainably managed forests and is primarily produced through an advanced solvent spinning process. This technology was developed by Lenzing AG of Austria and named Lyocell. Later, due to commercialization, it became widely known as "Tencel."
Tencel's primary component is cellulose, specifically derived from the pulp of fast-growing trees such as beech and eucalyptus. This wood is pretreated to extract pure cellulose molecules, which are then dissolved in the non-toxic solvent N-methylmorpholine-N-oxide (NMMO). Through a dry-jet wet spinning process, the cellulose solution is forced through a spinneret to form a fine stream. In a coagulation bath, the cellulose solution is regenerated into fibers, ultimately producing Tencel filaments or staple fibers with unique properties. This process achieves a high solvent recovery rate (over 99%), significantly reducing environmental pollution during production.
Tencel fiber has an irregularly round cross-section, a smooth surface, and a microporous structure. This property gives it excellent moisture absorption and breathability-its moisture regain reaches 11%, far exceeding cotton's 8%. Furthermore, Tencel is naturally skin-friendly, with a low coefficient of friction, making it suitable for sensitive skin. Furthermore, Tencel's strength approaches that of polyester, while combining the softness of cotton with the luster of silk. Its wrinkle-resistant and antibacterial properties can be further enhanced through blending or finishing processes.
In terms of environmental attributes, Tencel's entire life cycle meets sustainable development requirements: its raw materials are sourced from renewable resources, its production process is low-carbon and water-efficient, and its waste is biodegradable. Consequently, Tencel fabrics are gaining popularity in clothing, home furnishings, and other fields, becoming a high-end alternative to traditional cotton and linen fibers.
