Lenzing Ecovero™, Lenzing TENCEL™, TENCEL Modal™, TENCEL Luxe™, TENCEL Refibra™
Lenzing™ fibres are man-made from natural wood cellulose molecules derived from renewable sources and are eco-consciously manufactured with innovative and sustainable processes. At the end of their lifecycle, Lenzing™ fibres are fully biodegradable. Therefore they decompose back into their original components of C02 and water, preparing the ground for new plants to grow.

STSC represent Lenzing™ by offering Lenzing™ textiles through their Indian partner. Lenzing™, who is the producer of the yarn is based in Austria and have been working to develop the best environmental fabrics for the past 80 years.
These fabrics are trademarked to Lenzing™ and accredited as Closed-Circle systems using mills with high speed air jet & rapid looms. Lenzing™ is also able to supply's swing tags and high resolution logos for your products marketing. Therefore only trademarked accredited Lenzing™ fabrics can give the guarantee that they are accredited to the world standard. Fabrics showing the same name, such as TENCEL™ or Modal without the trademark, cannot be assured of being accredited closed-circle and of the highest sustainable standards that designers wish to uphold.
Additionally, fabrics using the name Lyocell (bamboo pulp) often listed as Made in China, and are not guaranteed to be accredited closed-circle system. Additionally, bamboo crops do not meet the highest environmental standards because they are water consumptive and the crops are non-replenish-able.
“This light and versatile material is a cellulosic fibre made by dissolving wood pulp, and it has exploded in popularity in recent years. As it is 50% more absorbent than cotton, its superior moisture-wicking and anti-bacterial properties make it ideal for use in activewear.
Requiring less energy and water than cotton, TENCEL™ is also biodegradable and according to Lenzing™, sourced from sustainably managed eucalyptus plantations.
Although it does require petrochemicals in the production process, they are used in a closed-loop system meaning the same solvent is recycled time and time again to minimise harmful waste.” - https://goodonyou.eco
The Lenzing’s wood and pulp utilised in all fabric blends are sourced from forests which are either FSC (Forest Stewardship Council) or PEFC (program for Endorsement for Forest Certification Schemes). 60% of the Birch and Eucalyptus trees used in Lenzing™ fibres are harvested from forests in Austria and Bavaria to minimise emissions and the fibre’s transport eco-footprint as its processed on-site at Lenzing™ Austria.
The Lenzing™ fibres are spun into yarns using a closed loop system which has significantly lower emissions and water impact than conventional viscose.
The yarn is then shipped to STSC’s fabric mills in India, China or Indonesia who Manufacture the Lenzing™ yarns into textiles. Woven fabrics include 100% Modal™, Modal™ and Linen blends, 100% TENCEL™ and TENCEL™LUXE (eco-couture for luxury brands) and blends.
We also wholesale ECOVERO™ woven as well as jersey knits using 100% ECOVERO™ and REFIBRA™ blends knitted in Indonesia.
Lenzing Tencel™ is a fibre made from cellulose wood pulp, a natural component sourced from FSC/ PEFC certified trees. The wood pulp is the converted into fibre using a non-toxic organic compound called N-Methylmorpholine N-oxide (NMMO) that has low toxicity and is filtered and recycled in a closed loop process, where 99.5% of chemicals are reused.
Composed from nano-fibrils which are hydrophilic ensures that tencel fabrics have a strong attraction to absorbing moisture, giving the fabric properties such as high absorbency and breathability. With a smooth hand feel, the fibre is soft on the skin and is luxurious in shine and low while having the exceptional capability for thermal regulation.
Lenzing™ Ecovero™ is a sustainable viscose with the lowest environment impact in the industry. These branded viscose fibres utilise certified and controlled sustainable wood sources which are created with ecological production processes while striving for supply chain transparency.
Ecovero™ is a semi synthetic cellulose fibre which is chemically manufactured from sustainable FSC / PEFC certified wood and pulp by extracting the long chains of cellulose molecules from the wood using sodium hydroxide (caustic soda). The cellulose is then dissolved and realigned to make useful long continues fibres. It is this plant-based chemical structure that gives Lenzing™ textiles their desirable properties, such as a natural next-to-skin softness, breathability and good moisture management.
Both Tencel Modal™ (viscose) and Lenzing Tencel™ (lyocell) are the same plant-based wood pulp fibres but are made using a slightly different process. Tencel Modal fibres are treated differently after spinning to make the filaments stronger. This involves stretching the fibres to increase molecular alignment, creating later and finer fibres which can be tumble dried without damage.
In some ways its a sturdier fibre especially for activewear, swimwear etc therefore we have blended Tencel Modal™ with ROICA™ V550 to make CircStretch eco-stretch collection. Also see woven's using 100% Tencel Modal™.
Tencel™ Luxe is the latest in eco-couture cellulose fabrics. The fine lyocell yarn can be compared to those of silk due to its airy feeling on the silk and the matte finish creating a fabric with a silky smooth feel and liquid like drape. This fibre stands out because of its extensive strength and high level of environmental compatibility. It is also perfectly suited for very fine fabric blending fibre of silk cashmere and wool.
Lenzing™ is “committed to setting industry standards in order to enhance the protection of our environment while making filaments for fabrics that are designed to appeal tp the most sophisticated consumers”.
STSC’s Tencel Luxe™ is currently blended with 100% GOTS Organic Peace silk to create our Malmal 80% Tencel Luxe™ & 20% Peace Silk and our Kela 55% Tencel Luxe™ & 45% Peace Silk. STSC is also working with Lenzing™ India to develop 100% Tencel Luxe™ fabrics as well as other Tencel Luxe™ blends.
Tencel™ x Tencel Refibra™
Tencel Refibra™ is a fibre produced by utilising the pioneering REFIBRA™ technology. This involves up-cycling a substantial proportion of cotton scraps, e.g. from garment production or post consumer waste and decomposing it into fibres alongside discarded lyocell wood pulp by using Refibra Technology.
World-renowned marine research institute confirms biodegradability of LENZING™ fibers
"Results of experiments conducted by the University of California’s prestigious Scripps Institution of Oceanography in San Diego provide further scientific proof that LENZING™ fibers offer an effective substitute to synthetic fibers that are part of the pressing problem of plastic pollution in our oceans.
The results of these experiments are striking: while wood-based cellulosic fibers fully biodegraded within 30 days, the fossil-based fibers tested were practically unchanged after more than 200 days."
“Working closely with our partners, Lenzing is evolving our product offering to further drive the decarbonization of the textile value chain.
The launch of the first CarbonNeutral® fibers under the TENCEL™ brand in September 2020 is a milestone on our shared path towards CO2 neutrality. The new CO2 neutral fibers are certified as CarbonNeutral® products for the textile industry in accordance with the Carbon- Neutral Protocol.
These carbon-zero TENCEL™ branded fibers will help Lenzing’s customers, especially brands and retailers to reduce their scope 3 emissions from raw material production and fulfill their scope 3 science-based target commitments.”
