Nanofibrils are the key to the performance possibilities of TENCEL®. The unique technology of nanofibrils allows the production of textiles, which, until now, could only be dreamed of. This is the first cellulose fiber to use this nano technology. Controlled and regular arrangement of nanofibrils in the TENCEL® fiber leads to new functional properties. The nanofibrils are hydrophilic and optimize absorption of moisture with excellent cooling properties.
Moisture transport as a result of nano technology. In contrast to synthetic fibers, with reduced wicking properties, TENCEL® offers unique moisture transport. The completely new nano technology of TENCEL® supports this natural fiber property, guaranteeing optimum conditions for the skin. Synthetic fibers cannot absorb moisture into the inside of the fiber. The illustration shows that in contrast to cotton and polyester fibers, TENCEL® controls and regularly absorbs moisture. Also TENCEL® absorbs 50 % more moisture than cotton. By contrast polyester does not absorb moisture.

Moisture transport is determined by climate. Depending upon climate conditions, TENCEL® either absorbs or releases moisture. Compared to other fibers, TENCEL® features the highest moisture absorption-rate: with air humidity at 65 %, TENCEL® still has unused capacity to absorb moisture from the skin.
The graph shows the increase of moisture in a textile when the textile is moved from a relative humidity of 65% to a relative humidity of 100%. The moisture refers to the weight of the dry textile.
The skin is the largest human respiratory organ. Human skin acts as a protective shell, regulates body temperature and maintains water balance. TENCEL® supports these body functions acting like a second skin.

A subjective feeling of well-being depends considerably on moisture absorption and on surface structure of the fibers. Rougher fibers can lead to skin irritation. The extremely smooth surface of TENCEL® feels soft and pleasant to the skin. The reason for the fine surface of the fiber is low fiber stiffness.
Smoothness across the board. A comparison of the fiber surfaces makes the difference patently obvious. TENCEL® fiber has a smoother and more supple surface than wool or cotton. Wool tends to have a scaly surface, while cotton is irregular and rough.

TENCEL® is a godsend for anyone with sensitive skin. The combination of a smooth fiber surface and excellent moisture absorption creates a positive environment for healthy skin, making TENCEL® ideal for anyone with sensitive skin.
According to recent dermatological studies, wearing clothing made of TENCEL® significantly improves comfort and promotes a feeling of well being.* (Dermatological study of the textile compatibility of TENCEL®, 2004, Univ.-Prof. Dr. T.L. Diepgen, Heidelberg, Germany) Also, TENCEL® is chemical free, an important factor for sensitive skin and another asset in comparison to other fibers of a natural origin.
When it comes to hygiene and the growth of bacteria, the inherent and natural properties of TENCEL® deliver a variety of benefits for sensitive skin.

TENCEL® does not give bacteria a chance to grow. Bacterial growth is prevented in a completely natural way. The perfect moisture management of the fiber is the key. When moisture is produced it is directly absorbed from the skin and transported to the inside of the fiber. Thus no water film is produced on the skin where bacteria could grow.
When it comes to water absorption capacity, TENCEL® is definitely superior to other fibers. Bacterial growth was observed in various fibers, and TENCEL®, with its rapid absorption of moisture and high absorption capacity proved most effective in inhibiting growth.
The result demonstrates that TENCEL® is the most naturally hygienic fiber. TENCEL® prevents the growth of bacteria naturally without the addition of chemical additives. With synthetic fibers on the other hand, the growth of bacteria increases 2000 fold in comparison to TENCEL®.
TENCEL® knows no limits. TENCEL® can be manipulated in a creative manner to produce a diversity of fabric aesthetics. Manipulating or controlling fibrillation produces a wide variety of fabrications, from suede-like or peach touch surfaces to a clean, smooth silky touch. Depending on the form of processing employed, very fine hairs form on the surface of the fiber to a greater or lesser extent.

TENCEL® has an extensive fiber portfolio which include filling and micro fiber variants. TENCEL® FILL is the answer to the search for a natural filling material for bedding. The excellent moisture management guarantees a pleasant and dry climate as you sleep. Moreover, TENCEL® regulates the temperature when sleeping.
TENCEL® MICRO, a very fine and smooth fiber type, completes the portfolio. The silky feel of TENCEL® MICRO is a guarantee of outstanding comfort.
TENCEL® offers a variety of styling possibilities. Fabrics with natural elongation and recovery properties can be created using innovative techniques without having to use elastomeric fibers.
The high tenacity of TENCEL® in both a wet and dry state increases the dimensional stability of the end product. Even a small percentage of TENCEL® in the yarn or fabric makes textiles particularly durable.
The future belongs to TENCEL®. The production of TENCEL® is revolutionary. The production process is based on a solvent spinning process. It represents the greatest achievement in cellulose fiber technology. The closed loop circuit recycling the solvent is what makes this process revolutionary. The solvent is recovered up to 99.5 % and the emissions, which remain, are decomposed in adapted biological purification plants. The manufacturing process was awarded the “European Award for the Environment” by the European Union.
The basis is a natural raw material. TENCEL® is extracted from wood pulp and is 100 % biodegradable. The wood used comes from tree farms that practice sustainability. Wearing TENCEL® makes you feel good.

TENCEL® has received numerous awards for its environmentally friendly manufacturing process. |
Wood is a replenishable raw material. For TENCEL® only wood from tree farms which practice sustainability is used.

The TENCEL® fiber can be used in a wide range of applications and contains no toxic substances. This purity makes it suitable for baby’s wear as well as adults. |
