Common Questions About TENCEL™ Lyocell

How is TENCEL™ Lyocell Made?

TENCEL™  Lyocell’s raw materials are rooted in nature. The wood used to make TENCEL™  is sourced from certified and sustainably managed forests. Different types of wood are used to make TENCEL™ . While eucalyptus is the main source, beech, spruce, birch, and pine are also used. A man-made, closed-loop process is then followed to transform wood into the fiber.

Making regenerative cellulose fibers requires two steps. In the first stage, pulp is produced from renewable wood. In the second stage, the wood pulp is dissolved in an organic, non-toxic solvent called NMO (N-Methylmorpholine-N-oxide). This forms a “cellulosic solution” which then goes through a solvent-spinning process. The mixture is pressed through tiny holes to form fiber strands which are treated and formed into bales that are later spun into yarn for clothing.

A Note on TENCEL™  Garment Production 

After TENCEL™ fibers are purchased by a fashion brand, they are then made into garments. The extent to which this process is sustainable and ethical depends on the brand.

In the realm of fast fashion, a cocktail of synthetic dyes and treatments are used to make clothing. Fast fashion brands also tend to outsource garment making to countries that exploit workers.

Pro tip: Opt for brands that are transparent about every step of the supply chain. Simply put, you should know how your TENCEL™ garment is produced, where it was made, and by whom. For example, we produce our TENCEL™ activewear in a GOTS-certified factory. We also use natural and non-toxic dyes and treatments. Check out our manufacturing process to see a 100% transparent supply chain in action!

Where is TENCEL™ Lyocell Made?

TENCEL™ Lyocell is sourced and produced worldwide with Lenzing headquarters based in Austria. Dissolving wood pulp production happens in Austria, the Czech Republic and Brazil. 

Austria, the United Kingdom, the USA, and Thailand are where the lyocell fibers are made.  Lenzing also obtains dissolving wood pulp in the global market. 

Take a look at the Lenzing location map for more information on production sites and office locations.

What is the Difference Between Lyocell vs TENCEL™?

In your search for more sustainable alternatives, you may have come across ‘TENCEL™ Lyocell’ and generic ‘lyocell’. Surely they are the same, right? Well, not quite.

In short, TENCEL™ is the trademark of the Austrian company Lenzing. They make the TENCEL™ branded lyocell fibers. Lyocell is the generic name for the plant-based fibers produced from wood pulp. TENCEL™ branded lyocell is often considered the gold standard in sustainable lyocell production. 

If you’re considering lyocell fiber clothing without the TENCEL™ trademark, it's worth doing some research before you buy. Without the TENCEL™ trademark, there’s no guarantee the fabric meets the same high standards or that its wood pulp is responsibly sourced from FSC or PEFC-certified forests. You don’t want to unknowingly fall into a greenwashing trap! 

Yet that’s not to say all lyocell fibers without the TENCEL™ trademark are unsustainable. For example, Excel by Birla is considered another eco-friendly lyocell alternative.

What is the Difference Between TENCEL™, Rayon and Modal?

Rayon. Modal. TENCEL™ Lyocell. Confused about the difference between these fabrics? If so, you’re not alone!

It’s easy to tangle them in the same web. For starters, all three originate from wood pulp and have the same silky smooth texture. 

Rayon (also known as viscose) and modal are the first and second generations, respectively, of cellulose fiber production. TENCEL™ Lyocell is the third generation, paving the way towards a more sustainable future for cellulose fibers.

So, how do rayon and modal production differ from TENCEL™ Lyocell? Let's unravel the basics!

Deforestation and Raw Material Sourcing

Due to their leafy origins, rayon and modal are often touted as eco-friendly materials. Yet the way the trees are sourced is unregulated and rooted in environmental concern. According to not-for-profit Canopy, around 50% of wood sourcing for rayon comes from ancient and endangered forests. Plus, 70% of the tree is wasted during production! 

In contrast, TENCEL™ Lyocell is sourced exclusively from sustainably managed forests.  They follow FSC and PEFC standards to reduce environmental impact. Lenzing also uses 100% of the tree. Go to the “TENCEL™ Lyocell and the Environment” section to learn more about Lenzing’s wood sourcing process.

Chemical Processing

Transforming trees into textiles for rayon and modal requires hazardous chemicals. The main culprits? Carbon disulphide and sodium hydroxide which are released throughout production. They poison the environment and devastate the lives of viscose workers and their communities.

TENCEL™ Lyocell, by comparison, uses a toxic-free and responsible production process. It’s also certified by designations like OEKO-TEX® STANDARD 100. This ensures high environmental and health standards are upheld.

Is TENCEL™ Natural or Synthetic? 

TENCEL™ Lyocell’s fibers are derived from cellulose – a natural polymer. The process of transforming wood pulp into regenerated cellulose fibers is man-made. This means TENCEL™ is considered semi-synthetic. 

The term ‘semi-synthetic’ might evoke images of plastic or chemically-infused materials. Yet it’s important to note TENCEL™ isn’t cut from the same cloth – quite the opposite, in fact! 

Lenzing’s lyocell process emerges as an eco-friendly alternative to viscose. It’s completely free from synthetic materials and toxic substances and only uses one non-toxic organic solvent during production. TENCEL™ may follow a man-made process, but it remains very sustainable and safe to wear.

Note: TENCEL™ can be blended with synthetic dyes and materials like elastane. The solution? Opt for TENCEL™  clothing mixed with natural dyes and materials like ROICA V550 – a non-toxic, compostable version of plastic-based elastane. ROICA V550 is what we use to make our TENCEL™ activewear stretchy and high-performing! 

TENCEL™ Lyocell and the Environment 

TENCEL™ Lyocell is an exceptionally eco-friendly material. This is because its production works with nature rather than against it.

Taking a leaf out of Nature’s book, Lenzing’s lyocell process follows the “cellulose cycle”.

It begins with photosynthesis to form cellulose – the essential building block of all trees and other plant life. The wood pulp that’s sustainably-sourced from trees is then transformed into lyocell fibers via a closed-loop, resource-saving process.  At the end of its life, TENCEL™ can biodegrade, returning to nature without leaving a trace.

This is radically different to synthetic and traditional viscose materials. Both follow a fossil fuel-dependent and chemically-intensive production. In other words, a linear process that has devastating consequences for the environment.

Plus, TENCEL™ gives waste a new life! Pre-consumer cotton scraps and post-consumer garments are sometimes mixed with the wood pulp. As a result, this diverts tons of waste from entering landfills and incinerations. TENCEL™ fibers with recycled content require 95% less water compared to conventional cotton. They also use significantly less land.

Does TENCEL™ Lyocell Contribute to Deforestation?

No, TENCEL™ Lyocell does not contribute to deforestation.

The wood used to make TENCEL™ is sourced from semi-natural forests and plantations. According to the European Environment Agency, a semi-natural forest is:

“A stand which is composed predominantly of native trees and shrubs species which have not been planted. Also, a forest which has been developed gradually or accidentally.”

Lenzing’s Wood and Pulp Policy outlines its deep commitment to sustainable forestry. This includes eliminating controversial wood sourcing such as illegal logging and extracting from endangered or ancient forests. 

Over 99% of the renewable wood and dissolving wood pulp used by Lenzing are certified by FSC and PEFC. If not certified, the forests are inspected in line with strict sustainability criteria. 

The timber for TENCEL™ comes from sustainable forestry practices like thinning, a process which removes select trees to improve overall forest health. As a result, wood unsuitable for high-grade products, such as furniture, finds a meaningful purpose in the production of botanic fibers. This also includes wood damaged by storms, droughts, or calamities.

In Europe, Lenzing also follows the 300-year-old silvicultural principle. This is where trees are felled only at a rate at which they can back.

Does TENCEL™ Use Lots of Pesticides and Water?

TENCEL™ Lyocell production doesn’t drain natural resources or cause environmental harm. The trees used for TENCEL™ are grown without the use of synthetic pesticides or fertilizers.

Lenzing’s sustainably-managed forests also play a vital role in the natural water cycle. This means they rely solely on rainfall–no artificial irrigation needed! By stabilizing local water ecosystems, they help prevent flooding and ensure a steady water supply during dry spells. In fact, forested catchments supply 75% of the freshwater used in TENCEL™ production.

Plus, Lenzing maximizes water efficiency by implementing closed water loops at their production sites, allowing for the reuse of water. The company’s Lyocell process uses around a third of the water needed in the traditional viscose process. 

Water stewardship is also a key focus in TENCEL™’s eucalyptus plantations. Learn more about Lenzing’s sustainable practices in the “How Sustainable is TENCEL™ Lyocell’s Eucalyptus Production?” section.

How Does TENCEL™ Production Protect Biodiversity?

TENCEL™ plantations prioritize biodiversity in multiple ways:

• Certified Sustainable Forests: FSC® and PEFC™ certifications ensure responsible forestry, protecting biodiversity and preventing illegal logging.
• Biodiversity Island in Austria: At Lenzing’s Austrian site, a wildflower meadow is planted between solar panels. This creates vital habitats for insects, birds, and native species while also generating renewable energy.
• 40-Hectare Green Belt: Lenzing maintains a protected forest around its main plant, providing a thriving habitat for wildlife. Sustainable forestry practices, such as selective tree removal instead of clear-cutting, help preserve ecosystems.
• Partnerships for Sustainable Plantations: Lenzing collaborates with its partners to manage eucalyptus plantations in ways that support biodiversity. More on this in the next section!

How Sustainable is TENCEL™ Lyocell's Eucalyptus Production? 

Eucalyptus can be a highly sustainable crop when sourced and produced responsibly–and TENCEL™ ensures just that! 

The problem with eucalyptus lies in intensive, unregulated monoculture. According to forest conservation charity Canopy:

“Eucalyptus is often grown on concessions that have had natural forest cleared and carbon-rich peatlands drained, causing massive social and environmental concerns. However grown in the right place, under the right conditions, eucalyptus can be fabulous!”

TENCEL™ 's eucalyptus is as sustainable as it gets. 

Lenzing sources eucalyptus from Sappi in South Africa and Dexco (LD Cellulose) in Brazil. All sourcing of eucalyptus for TENCEL™ aims to protect land, water, and biodiversity. 

Sustainability standards for TENCEL™’s eucalyptus plantations:

• Lenzing’s eucalyptus plantations rely on rainfall and do not require irrigation. They are also strategically located in areas with enough rainfall to prevent water shortages. 
• Lenzing’s eucalyptus plantations produce wood with high cellulose content and exceptional yields per unit. The result? Significantly reduced land use compared to other natural fibers!
• All plantations are certified or controlled by FSC® and PEFC™ standards – protecting natural resources and biodiversity. 
  

Sustainability standards for TENCEL™’s eucalyptus plantations in Brazil: 

• Works closely with the Brazilian Forestry Code (2012) – one of the most rigorous standards globally.
• 90,200 hectares of eucalyptus plantation is managed for wood.19,884 hectares are conserved to protect fauna and flora.
• Performs annual monitoring programs in dry and rainy seasons to assess impacts on local biodiversity.
• Establishes ecological corridors that link fragmented native rainforests, enabling wildlife and plants to migrate, thrive, and reproduce.
• Plantations are located in the Triângulo Mineiro region of Minas Gerais, over 800 km from the Amazon rainforest. No native forests are converted for eucalyptus plantation and works with Canopy to ensure strict sustainability standards are maintained. 
  

Sustainability standards for TENCEL™’s eucalyptus plantations in South Africa: 

• Approximately 35% of Sappi’s total land is dedicated to conserving natural habitats and promoting biodiversity.

• Sappi safeguards surrounding streams, rivers, and wetlands by maintaining buffer zones and regulating drainage to prevent erosion and runoff. Trees are not planted too close to riparian zones, minimizing water use impact.

• Sappi owns seven nature reserves and 160 other significant conservation sites. It also doesn’t harvest or buy wood from any tropical natural forest areas. 

Does TENCEL™ 's Eucalyptus Production Harm Koalas and Their Habitats?

No, TENCEL™ Lyocell production doesn’t harm koalas and their habitats. The eucalyptus sourced for TENCEL™ is grown in Brazil and South Africa. Koala habitats are found in Australia where vast native eucalyptus forests grow. 

A Note on Trees and Climate Action

Did you know wearing TENCEL™ Lyocell isn’t just a fashion choice, it’s a powerful step toward climate action? This is because sustainably sourced wood is inherently renewable. Simply put, trees grow back! 

Forests are a vital tool in the fight against climate change. They are natural carbon sinks, absorbing twice as much CO2 as they emit each year. Trees naturally soak up carbon as they grow which then converts it into plant matter through photosynthesis. 

When trees die and decay, they release CO2 back into the atmosphere. Unlike the fossil fuel industries, the forest ecosystem has a unique “give and take” relationship with carbon. This makes wood, if sourced responsibly, an extremely eco-friendly material to produce, and wear!

That said, monoculture forests – if not managed sustainably – can actually turn into carbon emitters. Because they lack biodiversity, they’re more prone to pests, diseases, and fires – all of which release carbon. In contrast, natural forests with multiple tree species store 70% more carbon compared to monoculture systems. 

Monoculture woodland can also deteriorate soil health (healthy soils are essential for carbon storage!) and are often planted by clearing natural forests. This further releases CO2 and wipes out native ecosystems.

So, how does TENCEL™ tackle the problems linked to monoculture forests?

As mentioned above, much of the wood used for TENCEL™ comes from semi-natural forests, which are crucial for biodiversity and act as effective carbon sinks. 

Unlike monoculture plantations, semi-natural forests aren’t created by clearing native grasslands or converting endangered ecosystems. Instead, TENCEL™ relies on sustainable forestry practices, such as thinning and silviculture. These methods encourage biodiversity, help with soil health, reduce the risk of wildfires and promote water security.

What about Lenzing’s eucalyptus plantations? Aren’t they essentially monoculture?

Yes, eucalyptus plantations are considered monocultures. But when managed sustainably, eucalyptus can actually store lots of carbon. 

Lenzing follows strict environmental standards, ensuring no native forests are cleared to make way for their plantations. Plus, by responsibly managing eucalyptus, they actually help take the pressure off natural forests, which protects wildlife and water supplies.

And don’t forget: all the wood used for TENCEL™ is FSC and PEFC certified. That means it meets high sustainability standards, keeping forests as carbon sinks instead of carbon emitters!

Does TENCEL™ Lyocell Require Lots of Resources to Produce? 

The manufacturing of TENCEL™ Lyocell operates within a closed cycle. This means the resources used to transform wood pulp into fiber are not intensive, wasteful or cause harm to the natural world. 

Here’s how Lenzing ensures circularity throughout the forest to fiber production process:

• Energy: Traditional pulp and fiber production is energy-intensive. To address this, Lenzing has developed innovative biorefinery technology. The wood not used for TENCEL™ fibers is transformed into thermal energy and electricity. Many of the major TENCEL™ production sites are powered by bioenergy. Lenzing's pulp factories actually produce excess green energy which is used or supplied to the local power grid.
• Water and Solvents: Water is used to dissolve wood pulp along with one organic solvent N-methylmorpholine N-oxide (NMMO). After the TENCEL™ fibers are made, the evaporated water is captured and fed back into the process. Up to 99.8% of water and chemicals are recovered and reused. Only a tiny fraction of wastewater is sent to treatment plants to be purified. 

What Sustainable Certifications Does TENCEL™ Lyocell Have?

Sustainable certifications are meaningful designations given by third-party bodies. They verify a product or company is meeting high environmental and social standards. 

In a sea of greenwashing claims, certifications are your best friend. They give you the confidence you need to make truly sustainable and healthy fashion choices. 

TENCEL™ Lyocell fibers are covered by several credible certifications. This means you can trust the fabric hugging your skin is good for your health, the planet, and the people who made it. 

Here’s a brief overview of some of TENCEL™’s key sustainability credentials: 

• EU Ecolabel is a world-renowned voluntary scheme which demonstrates “environmental excellence”. This means TENCEL™ maintains high environmental standards from creation to disposal. 
• OEKO-TEX® STANDARD 100 is another globally recognized standard, testing textiles for harmful substances. This means TENCEL™ is certified safe and presents no harm to the wearer or the environment. 
• FSC® and PEFC  certifications confirm that TENCEL™ wood sourcing follows strict sustainability criteria.
• TÜV AUSTRIA certifies TENCEL™ fibers are 100% biodegradable and compostable.

Is TENCEL™ Lyocell Biodegradable?

Yes, TENCEL™ Lyocell is certified to be biodegradable and compostable. Simply put, it can return to its natural origin – nourishing the environment, rather than polluting it. 

Under the right conditions, TENCEL™ can degrade in salt water, fresh water, soil and compost. 

Unfortunately, the same can't be said for common synthetic materials like polyester and nylon. When washed or thrown away, synthetics shed toxic microplastics. These tiny plastic particles are insidious by nature. They contaminate ecosystems, harm wildlife, and have even been found in the human body.

A study by California’s Scripps Institution of Oceanography compared the biodegradability of polyester and TENCEL™ over time in oceanic conditions. The results were striking: TENCEL™ fibers fully biodegraded in just 30 days. The polyester fibers remained largely unchanged even after 200 days.

So, does this mean I can compost my old TENCEL™ clothing at home?

100% TENCEL™ Lyocell fibers are certified by TÜV AUSTRIA for home composting. Still, it’s important to consider a few factors before you settle your old TENCEL™ clothing into its forever (humus) home:

• Check the clothing label first. It could be interlaced with other non-biodegradable materials. If in doubt, reach out to the brand that made the garment to confirm if it’s safe to compost. 
• Make sure you’ve set up proper composting conditions. This includes the right balance between carbon-rich materials (browns), nitrogen-rich materials (greens), water (moisture), and air (oxygen). 
• Consider repurposing or recycling your clothing first. We would always recommend trying to extend the life of your clothing for as long as possible. Composting should be the final resort. 

TENCEL™ Lyocell and Health 

Is TENCEL™ Lyocell Toxic?

TENCEL™ Lyocell is 100% toxin-free. It’s designed to protect your health and is incredibly safe to wear against your skin. 

In today’s fast fashion world, it’s common practice for our clothing – particularly activewear – to be injected with toxic chemicals. Why? To boost convenience and performance. However, these residues have been found to linger in fabrics, exposing our bodies to harmful substances over long periods of time. 

This is where TENCEL™ really changes the game. It combines the best of nature and performance without relying on toxic chemicals. The non-toxic organic solvent N-methylmorpholine N-oxide (NMMO) used to make TENCEL™ fibers is removed after the fiber is spun. It's also certified by OEKO-TEX® STANDARD 100, guaranteeing the fibers are free from hazardous chemicals.

Note: Be mindful of the finishes and dyes applied to TENCEL™ Lyocell fabric. The treatment and dyeing stages can be one of the most toxic aspects of garment production. When purchasing TENCEL™ clothing or activewear, check for sustainable certifications. For example, at Tripulse, we use gentle, water-based dyes that are certified by OEKO-TEX® and are REACH compliant. This ensures our TENCEL™ activewear protects your health while empowering you to move with confidence and comfort.

Is TENCEL™ Lyocell Skin-Friendly?

Absolutely! TENCEL™ Lyocell is naturally hypoallergenic and the perfect choice for those with sensitive skin. Its ultra-smooth surface ensures a gentle, non-irritating feel, even during prolonged wear. That’s why it’s ideal for intimate clothing like activewear and underwear.

TENCEL™ naturally cares for your skin. Its advanced moisture management system pulls sweat away from your body and into its fibers, allowing it to evaporate efficiently. The lack of moisture discourages the growth of skin-irritating bacteria. This means your skin will always feel dry, comfortable, and itch-free! TENCEL™’s thermoregulating properties are also naturally cooling and prevent overheating.

This is the complete opposite of non-hypoallergenic fabrics like polyester and nylon. These plastic-based fabrics trap heat and sweat, leaving you feeling sticky, itchy, and uncomfortable. Plus, if you’re allergic to wool or find it irritating, TENCEL™ is a fantastic alternative. It’s so much softer, smoother, and gentler on the skin.

Added skin-friendly bonus: TENCEL™ is certified by OEKO-TEX® and Blue Label by Asthma Allergy Denmark. These certifications guarantee it’s free from the skin-irritating toxins and dyes used in most conventional fabrics.

Is TENCEL™ Breathable?

Yes, TENCEL™ Lyocell is highly breathable. Its unique fiber structure promotes airflow and helps regulate body temperature. 

This is why TENCEL™ is the ideal fabric for activewear. It lets your body breathe while providing the flexibility you need to reach your goals.

Conventional fabrics such as polyester have the opposite effect! They are densely woven fibers that trap sweat and heat, preventing air from circulating easily. You end up feeling stuffy and restricted in clothing that stops you reaching your full potential. 

Does TENCEL™ Lyocell Make You Sweat?

No, TENCEL™ Lyocell doesn’t make you sweat. Its natural fibers excel at managing moisture, keeping your body cool and dry even during intense movement. 

This is where TENCEL™ natural superpowers really shine. By reducing moisture, TENCEL™ prevents odor-causing bacteria from lingering in the threads. You can perform at your best without feeling sweaty, smelly and uncomfortable. Plus, your clothes stay fresh for longer which means fewer washes and outfit changes.

Now, let's bust a common workout myth!

It’s easy to assume that odors are just a natural part of working out. Yet it’s often not you that smells–it’s your workout clothes. Common synthetic sportswear such as polyester, nylon and acrylic trap moisture. This creates the perfect haven for bacteria and bad smells to thrive. A study by Lenzing compared TENCEL™ and polyester activewear in extreme sports. The results showed that odor and bacterial growth were significantly worse in polyester.

Plus, many of our customers simply air-dry their TENCEL™ activewear and it's good to go again the next day! Sounds game-changing, right?! 

Here’s what Tripulse customer Michaela has to say:

“Our technical innovation unlocks the inherent potential of TENCEL™ Lyocell fibers for producing stretch fabrics that move in harmony with the body. This enhances comfort with easy-to-care properties, making it ideal for lightweight apparel,” – Rex Mok, Vice President of Fiber Technical Marketing and Development at Lenzing.

Is TENCEL Lyocell Good For Hot Weather?

Yes! TENCEL™ Lyocell is one of the best fabrics to wear in hot weather. This is due to its naturally cooling, moisture-wicking, odor-resistant and thermoregulating properties. TENCEL™ fibers gently hug your skin, keeping your body cool while drawing sweat away from the body. Unlike denser fabrics such as denim and plastic-based materials, TENCEL™ won't cling, feel tight or uncomfortable.

Caring for TENCEL™ Lyocell 

Does TENCEL™ Lyocell Wrinkle?

TENCEL™ Lyocell is naturally wrinkle-resistant. This makes it a low-maintenance and hassle-free choice for everyday wear and travel.

To avoid wrinkles after washing and between wears, follow these tips:

• TENCEL™ garments generally dry wrinkle-free. To ensure the best results, remove them from the washing machine promptly. Air-dry by hanging them up or laying them flat before storing.
• To avoid wrinkles between wears, always air-dry your garments straight after use.
  

If wrinkles do appear:

• For light wrinkles, use a steamer to refresh the fabric.
• For more pronounced wrinkles, an iron on a low-heat setting can help. Try to avoid ironing whenever possible to preserve the fabric’s integrity.

Note: Always follow the instructions on the care label before steaming or ironing.

Does Tencel Lyocell Shrink?

TENCEL™ Lyocell may shrink slightly (about 3-5%) during the first wash. It typically stabilizes and holds its shape beautifully afterwards.

To prevent further shrinkage, follow the care instructions provided for your garment. TENCEL™ is sensitive to high heat which can cause the fabric to shrink. For best results, gently wash it on a cold cycle (low temperature, max 30°C/86°F) and avoid using a dryer. Instead, air-dry your garments to maintain their shape and longevity.

At Tripulse, we account for TENCEL™ shrinkage in our sizing guides, ensuring the recommended size fits perfectly even after washing.

Does TENCEL™ Lyocell Pill?

TENCEL™ Lyocell is highly resistant to pilling. This is due to its ultra-smooth fiber surface and premium production process. TENCEL™’s uniform threads minimize friction and reduce the chances of threads breaking loose. Other natural fabrics such as wool are more prone to pilling due to their irregular texture.

That said, no fabric is entirely immune to pilling. You can keep your TENCEL™ garments looking pristine by following a few simple care tips. For instance, turn your clothes inside out before washing them on a cool, gentle cycle or hand wash. Always air dry and avoid using the tumble dryer.

Thanks to TENCEL™'s natural odor resistance, you don’t need to wash your clothes as often. This further reduces friction and helps to prevent pilling!

TENCEL Lyocell vs Other Fabrics

How Does TENCEL™ Lyocell Compare to Synthetic Materials Like Polyester?

Synthetic materials have long been steadfast staples in our wardrobes, particularly for activewear. Yet wrapping ourselves in plastic may not be the most practical or healthy choice. 

Here's how TENCEL™ Lyocell outshines synthetics:

• TENCEL™ Lyocell lets your body breathe while synthetics trap heat and sweat. One study tested a group of individuals performing strenuous, sweat-inducing exercise. They were wearing t-shirts with two halves– one side TENCEL™ and the other polyester. TENCEL™ was much better at keeping the body cool and effectively wicking sweat away from the skin. 

• TENCEL™ Lyocell is naturally high-performing without relying on toxic chemicals. In contrast, sweating in synthetic fabrics can expose you to harmful toxins. Many are treated with hazardous substances including carcinogens and hormone-disrupting agents. When you sweat, your pores open up, making it easier for the toxic residues to absorb into your skin.

• TENCEL™ Lyocell is skin-friendly and antibacterial while synthetic materials can aggravate sensitive skin. The bacteria and moisture that linger in plastic-based threads can irritate the skin. Disperse dyes are often added to synthetic clothes which can also cause skin problems. 

• One of the major downsides of synthetic fabrics is their inability to biodegrade. They can often take decades or even centuries to break down. TENCEL™, being plant-based, is biodegradable and decomposes naturally. Biodegradable synthetics do exist but they take much longer to degrade than TENCEL™ and can release harmful toxins in the process.

• Synthetic fabrics are dependent on fossil-fuels and release harmful microplastics. Even biodegradable polymers release “biomicroplastics” which have proven to be just as toxic as conventional microplastics. As TENCEL™ is derived from wood, it's 100% plastic-free!

Is TENCEL™ Lyocell Better Than Cotton?

Both TENCEL™ and cotton are natural fibers, but TENCEL™ offers clear advantages for an active and sustainable lifestyle: 

• Performance: TENCEL™ is a game-changer when it comes to performance. Unlike cotton, which can feel heavy and clingy when wet, TENCEL™ retains an impressive 85% of its strength when wet. It’s also 50% more absorbent than cotton. This means it manages moisture better, resists odor, and keeps you feeling fresher for longer. Cotton tends to hold onto moisture, leading to discomfort and odor from bacteria buildup.

• Chemical Use: Conventional cotton relies heavily on harmful pesticides, which harm ecosystems and cotton farming communities. In contrast, TENCEL™ is made without toxic chemicals in a resource-efficient, closed-loop process. 

• Land Use: TENCEL™ is very land-efficient, needing far less space than cotton. In fact, Lenzing fibers deliver four times the fiber yield per acre compared to cotton. What’s more, the beech and eucalyptus trees used for TENCEL™ can thrive on land that isn’t suitable for growing food. Cotton, on the other hand, requires high-quality farmland to grow.

• Water Management: Unlike lots of cotton crops, the trees used for TENCEL™ don’t need artificial irrigation. Cotton farming can use 20 times more water than TENCEL™ and is often grown in water-stressed areas, which can cause problems if farmers aren’t supported properly. TENCEL™ takes water stewardship seriously, using sustainable practices to manage resources responsibly. This is especially true for eucalyptus, which needs careful handling to avoid water scarcity.

• Health and Skin-Friendly Benefits: TENCEL™ is naturally smoother than cotton, so it’s gentler on the skin and causes less chafing and irritation. It’s also hypoallergenic and free from toxins. While cotton is hypoallergenic in its purest form, it’s often treated with azo dyes or pesticides that can irritate the skin. 

Is TENCEL™ Healthier and More Sustainable Than Organic Cotton? 

TENCEL™ Lyocell and organic cotton are both considered safe and sustainable clothing options. That said, TENCEL™  edges slightly ahead when it comes to environmental impact and transparency.

Note: Organic cotton has the same natural fiber composition and performance features as conventional cotton. This means it shares the same challenges with moisture management and odor control.

Environmental Impact

Organic cotton is grown without toxic pesticides. Fairtrade organic cotton uses 14% less water than conventional cotton. 80% of organic cotton is rainfed which reduces irrigation. However, lower yields from non-GMO crops mean organic cotton requires more land and water overall.

TENCEL™, on the other hand, is a low-impact, resource-efficient fabric. Sourced from sustainably managed forests, it doesn’t rely on farmland or irrigation. Its closed-loop production recycles 99.8% of water and chemicals. Plus, TENCEL™ 's eucalyptus plantations produce high-yield wood, using significantly less land and resources. 

Greenwashing

Organic cotton often comes with a complicated and fragmented supply chain, leaving room for mislabeling and fraud. Indian organic cotton has been at the center of controversy, with investigations uncovering that much of it wasn’t organic at all. As the New York Times put it, “an opaque certification system rife with opportunities for fraud” lies at the heart of the issue. Even GOTS, the gold standard in organic certification, had to ban 11 companies for mislabeling 20,000 tons of cotton.

Currently, no major greenwashing scandals have touched TENCEL™. Produced exclusively by Lenzing, it has robust sustainability certifications and a transparent, tightly controlled production process. However, as with any fabric, transparency depends on the brand’s practices and marketing. 

Is TENCEL™  Lyocell Better Than Merino Wool?

TENCEL™ Lyocell and merino wool are powerful natural alternatives to synthetic clothing. 

Both fabrics are naturally soft, odor-resistant and excel at managing moisture. Yet in many ways, merino wool pales in comparison to TENCEL™ supernatural qualities.

Here's why TENCEL™ is the superior choice for your workouts and beyond:

• Performance and Durability: Lightweight merino wool, like baselayers and casual shirts, often pills and develops holes with regular wear. TENCEL™, with its strong and resilient fibers, stands up to wear and tear, meaning your clothes last longer.

• Chemical Use: Merino wool often follows the superwash process. This involves harsh chemicals to make it machine-washable and shrink-resistant. In contrast, TENCEL™ only uses one non-toxic organic solvent during production. Plus, OEKO-TEX® certifies it's free from harmful substances.

• Land and Water Use: Both merino wool and TENCEL™ are natural and biodegradable. As it's derived from livestock, merino wool requires large amounts of land, water and energy to produce. TENCEL™ is less resource-intensive. It's sourced sustainably using fast-growing FSC and PEFC-certified trees and produced within a closed-loop system that recycles chemicals and water.

• Vegan and Ethical: As an animal-derived fabric, merino wool raises ethical concerns. This includes the controversial practice of mulesing. TENCEL™ is entirely plant-based, offering a cruelty-free option for conscious consumers.

• Skin-Friendly Properties: Merino wool is soft and becomes smoother with wear. However, for some, it can feel itchy, especially on sensitive skin. TENCEL™ offers a silky-smooth texture that creates less friction, making it the perfect choice for irritation-free movement.

Common Concerns and Objections

What Are the Disadvantages of TENCEL™ Lyocell?

While TENCEL™ Lyocell offers remarkable benefits, there are a few considerations to keep in mind:

• Extra Maintenance: As a natural fiber, it requires a bit of extra care compared to synthetic materials. It’s sensitive to high heat, so it’s best washed on a low heat setting or by hand to avoid shrinkage. The good news? TENCEL™ doesn’t need frequent washing thanks to its natural odor resistance. A quick air-dry after use often leaves it smelling as fresh as after a full wash.

• Not Readily Available: TENCEL™ is still a relatively new fabric and not yet widely accessible. Many brands using it are slow fashion labels with smaller collections.

• Higher Price Point: Compared to cheaper materials like polyester and nylon, TENCEL™ comes at a premium. However, this cost reflects its superior quality, sustainability, and ethical production. Discover the true value behind TENCEL™ in the next section!

Why Is TENCEL™ Lyocell Expensive?

Ever wondered why TENCEL™ Lyocell clothing comes with a higher price tag? It’s because every thread reflects a deep commitment to ethical and sustainable practices. 

Before it's turned into clothing, TENCEL™ fibers go through a premium, eco-friendly process. If purchased by a conscious brand, the fibers are carefully crafted into high-quality clothing with deep consideration for the wearer’s health, the planet, and the well-being of the garment workers. This focus on high standards and certified quality adds to the cost. Yet it’s worth it for a product that is truly responsible and made to last!

Now, let’s talk about fast fashion–the culprit behind those “too-good-to-be-true” prices. Cheap plastic-based materials, harmful chemicals, and exploitative labor practices are standard. This leads to clothing that deteriorates quickly, exposes you to microplastics and harmful toxins, and contributes to pollution that lasts for generations.

But what if we flipped the destructive fast fashion model on its head and embraced a “less but better” approach? Could investing in a few high-quality TENCEL™ pieces, less frequently, actually be the smarter, more cost-effective choice?

Picture a wardrobe filled with timeless, versatile essentials–pieces you’ll love and wear for years. Garments that feel incredible against your skin, perform effortlessly, and adapt to your lifestyle. No restrictions. No compromises.

Shifting to a slow fashion mindset with TENCEL™ doesn’t just simplify your life, it saves time, money, and energy in the long run. More importantly, it’s a meaningful investment in your health, happiness, and a more sustainable future.
