Raw material - eucalyptus

The basis for TENCEL® is eucalyptus wood solely grown in sustainable forestry. Eucalyptus is an interesting raw material, as it is fast growing and can be planted for industrial use in so called “wood farms”- without artificial irrigation or genetic engineering. It is an evergreen plant and can grow up to 40 meters.

The eucalyptus tree originates from Australia and Tasmania as well as eastern Indonesia. Nowadays some species are also grown in different other subtropical countries in the world. In Australia 70 % of the tree population consists of eucalyptus. There’s no other continent with such a domination by one single kind of tree.


Eucalyptus is being barked, hackled and boiled up until the so called “wood fiber pulp” develops. This pulp is the mass where the natural cellulose fibre TENCEL® is gained from. During the production process for TENCEL® the cellulose is being solved in an organic solvent (aminoxid, which is also used in body cosmetics), extruded again using a wet-spinning method and regenerated to the fiber.


Due to its nano fibril structure TENCEL® combines a variety of advantages.

Moisture management

In a very natural way TENCEL® absorbs excessive moisture and yields it back to the environment. New functional features can be created thanks to the controlled and regular arrangement of the nano fibrils in the TENCEL® fiber. Nano fibrils are hydrophilic and guarantee an ideal absorption of humidity with an optimal microclimate on the skin

The ideal moisture transport is unique compared to synthetic fibers. Those are not able to absorb humidity into the inner fiber. Compared to cotton TENCEL® absorbs 50 % more humidity. With an air humidity of 65 % TENCEL® in contrast to other fibers has still capacities to transport wetness away from your skin.

Skin sensibility

The skin is our biggest respiratory organ. It protects us, regulates our body temperature and maintains our water balance. TENCEL® supports those functions and acts like a second skin. The subjective wellbeing depends strongly on moisture absorption and the structure of the fiber surface. Harsh fibers in particular can lead to skin irritations. TENCEL® has an extraordinarily smooth surface and guarantees a feeling like being “fondled”. The secret of its smooth surface is the low stiffness of the fiber.

When comparing the surface of cotton, wool and TENCEL® fibers, the difference is obvious. Wool has a flaked surface while cotton has a rugged and snatchy one. TENCEL® on the other hand is smooth and limber.

The combination – smooth fiber surface and ideal moisture absorption – favours a positive microclimate on the skin, reducing the disturbances of people with delicate skin. According to a research conducted in Germany wearing clothes made of TENCEL® helps to improve the subjective well-being. (Dermatological research on skin kindness of TENCEL®, 2004, conducted by Univ. Prof. Dr. T.L.Diepgen, Heidelberg, Germany).

Furthermore the use of chemicals in the fiber plays a crucial role when it comes to very delicate skin. TENCEL® is pure and does not irritate the skin. One more advantage compared to other natural fibers.

Hygiene in a natural way

When it comes to hygiene and bacterial growth, TENCEL® due to its natural properties offers whole new perspectives that help our skin to relax and look healthier. Bacterial growth has no chance on TENCEL®. In a natural way bacterial growth is being avoided. The decisive factor for this is the fiber’s optimal moisture management.

When humidity emerges it is transported directly from the skin into the inner fiber. Therefore no liquid film develops on the skin and bacteries cannot emerge.

Completely without any addition of chemicals TENCEL® prevents bacterial growth. In synthetic fibers bacterial growth is 2.000 times higher than in TENCEL®


High firmness in wet as well as dry conditions increases the stability of each textile product. Even if TENCEL® accounts for only a small share of the yarn or tissue, the cloth becomes particularly resistant.

Sustainable progress derives from nature

The production of TENCEL® is revolutionary. The production process is based on a spinning method using organic solvent and it presents the most important achievement in cellulose fiber technology. The revolutionary part is the recycling system leading the solvent through the process. The solvent is being recycled to 99,5 %, the remaining emissions are degraded in adapted biological clarification plants.

The production process has been awarded with the “European Award for the Environment” by the European Union. TENCEL is gained from eucalyptus wood and thus bio-degradable to 100%. The wood used to produce TENCEL is grown in sustainable forestry.


The Lenzing company has been awarded with the European ECO-Label. This award is given only to the best companies in their industry, as the European Union sets very stringent directives that have to be followed in order to receive the award. Not only the product itself is being controlled, but the whole production process. The ECO-flower therefore stands for the best eco-friendly products.

TENCEL® – the eco fiber

In contrast to the cultivation of conventional cotton eucalyptus does not need any use of water or pesticides. Furthermore it can be grown on margin areas that cannot be used for food production. The crucial advantage is that TENCEL® fibers produce an outcome which is ten times higher than the outcome of conventional cotton fibers.

6 square meters of ground are the basis for one cotton T-shirt or even 10 T-shirts made of TENCEL®. An argument getting more and more important in a world where the population is fast growing and ground is a scarce property.
