What is Tencel? A Look at this Popular Fiber
- 5 minute read -
Tencel, a fiber created by the Austrian company Lenzing, has gained attention in recent years as a more sustainable alternative to other fabrics like cotton, polyester, and rayon. Known for its softness, breathability, and eco-conscious production process, Tencel is essentially a type of lyocell or modal, fibers derived from wood pulp. While it’s marketed as environmentally friendly, its production process and benefits also have some nuances worth considering.
What Exactly is Tencel?
The process of making Tencel involves sourcing wood, often eucalyptus, beech, or spruce, and breaking it down into pulp. This pulp is then dissolved with a solvent, turned into fibers, and spun into yarn. Unlike traditional rayon production, which can be resource-intensive, Tencel production uses a “closed-loop” system, meaning most of the water and chemicals are recycled within the process. This has led to Tencel being touted as a more sustainable fiber choice.
Pros of Tencel
Soft and Breathable: Tencel is known for its smooth texture, often described as being softer than cotton, making it ideal for items like bed linens, clothing, and activewear.
Moisture-Wicking: Tencel is effective at wicking moisture away from the skin, which makes it suitable for warm climates and exercise wear.
Hypoallergenic Properties: Due to its smooth fibers, Tencel is less likely to irritate sensitive skin compared to rougher fabrics.
Reduced Environmental Impact: The closed-loop process used in Tencel production limits the chemical waste and water used compared to other fabric manufacturing methods, particularly traditional viscose rayon.
Considerations and Critiques
While Tencel’s production process uses fewer resources and is marketed as eco-friendly, it’s not without criticism. Here are a few considerations:
Chemical Use: Although Tencel production recycles most of its solvents, it still requires the use of chemicals. The environmental impact largely depends on how well individual manufacturers uphold the closed-loop process.
Wood Sourcing and Deforestation: The sustainability of Tencel is closely tied to responsible sourcing. Using certified sustainable forests is crucial to ensuring that the wood used doesn’t contribute to deforestation. However, the demand for Tencel could potentially lead to unsustainable logging practices if it continues to grow rapidly.
Price: Tencel can be pricier than cotton and synthetic alternatives, as its production process is more specialized. This means consumers may end up paying a premium for a more sustainable label, which isn’t always accessible to everyone.
Tencel vs. Other Fabrics
Compared to cotton, Tencel is marketed as being more sustainable due to its closed-loop process and efficient resource use. Cotton, however, is naturally renewable and doesn’t require chemical solvents for production, although conventional cotton farming can be water-intensive. In contrast, synthetics like polyester and nylon are petroleum-based, so Tencel offers an alternative with a smaller carbon footprint. However, Tencel’s status as a “natural” fiber is sometimes questioned due to the chemical steps involved.

Tencel has positioned itself as a responsible choice in the textile market, offering a more environmentally friendly process than many synthetic fibers and traditional rayon. However, while its benefits are appealing, it’s important to remember that Tencel’s environmental impact still depends on responsible sourcing and production practices. As with many sustainable options, Tencel presents a promising, but not perfect, choice for those seeking lower-impact clothing options.
For shoppers interested in sustainability, Tencel can be a positive choice among other natural and eco-friendly fabrics—but, as with any material, understanding the full production story can help make a more
informed decision.
