Tencel is the brand name for a family of lyocell fibres made from FSC-certified wood pulp, produced through a closed-loop solvent process that recovers 99.5% of the chemistry used (Lenzing AG, 2024). It's the fastest-growing "preferred fibre" in the European market, with global lyocell demand up 22% year-over-year in 2024 (Textile Exchange, 2024). For fashion brands sourcing production in Portugal, understanding Tencel is the difference between a dress that flows and photographs beautifully, and one that feels stiff on-body.
This guide covers what Tencel actually is, how it's made, the difference between Tencel and generic lyocell, the GSM tiers available for tencel wear in 2026, real EUR pricing per meter across the northern Portuguese textile cluster, MOQ patterns for tencel garments, and how it compares to cotton and modal. Everything below reflects the manufacturer-side view, based on production runs coordinated across our factory group in the Porto, Guimarães, Braga, Barcelos, and Famalicão regions.
Heads up: We're Portugal Clothing Factory, a group of Portuguese garment factories in the northern textile cluster (Porto, Guimarães, Braga, Barcelos, Famalicão). We've documented 80 factories across the region and verified 25 active producers, so the observations in this article come from that research and from lyocell clothing production runs placed across the group between 2024 and 2026.
Key Takeaways
- Tencel is Lenzing's branded lyocell fibre, spun from FSC-certified eucalyptus, beech, and spruce pulp in a closed-loop process that recovers 99.5% of solvent (Lenzing AG, 2024)
- Lyocell fibre demand grew 22% year-over-year in 2024, faster than any other cellulosic fibre (Textile Exchange, 2024)

What Is Tencel Fabric?
Tencel is the registered brand name Lenzing AG uses for its lyocell and modal fibres, both regenerated cellulosic yarns spun from sustainably harvested wood pulp. Roughly 100% of Lenzing's wood inputs came from FSC or PEFC-certified forests in 2024, and the process holds EU Ecolabel certification (Lenzing AG, 2024). In fabric form, Tencel is soft, drapey, moisture-wicking, and biodegradable.
The name "Tencel" specifically covers three fibre types: Tencel Lyocell (the flagship), Tencel Modal, and Tencel Luxe (a filament yarn). Most tencel fabric you'll see on the market is Tencel Lyocell, either in 100% form or blended with cotton, wool, or elastane. The fibre feels closer to silk than cotton, with a fluid drape and a slight sheen that photographs well.
Within the cellulosic family, Tencel sits above generic viscose (rayon) in both performance and environmental profile. Viscose uses an open chemical process; Tencel uses a closed-loop system. Viscose weakens sharply when wet; Tencel keeps roughly 85% of its dry strength when wet. That single property is why Tencel wear survives washing better than most other regenerated fibres.
Citation Capsule: Tencel is Lenzing AG's branded family of lyocell and modal fibres, spun from FSC and PEFC-certified wood pulp using a closed-loop solvent process. In 2024, Lenzing sourced roughly 100% of its wood from certified forests, and the fibre carries EU Ecolabel certification for reduced environmental impact (Lenzing AG, 2024).
Other names you'll see
Tencel is often referred to as "lyocell", though the two are not fully interchangeable. All Tencel is lyocell; not all lyocell is Tencel. Generic lyocell can be produced by any mill under the ISO name "lyocell fibre". Tencel requires a Lenzing supply agreement and comes with brand traceability. In Portuguese factory documentation, you'll see "lyocell", "Tencel", or "malha lyocell" for knit versions.
How Is Tencel Made?
Tencel is made through a closed-loop lyocell process that dissolves wood pulp in N-methylmorpholine N-oxide (NMMO), a non-toxic organic solvent. According to Lenzing's own operations data, 99.5% of the solvent is recovered and reused across production cycles, a level of chemistry recovery unmatched by conventional viscose (Lenzing AG, 2024). The process was patented by Lenzing in the 1990s and remains the gold standard for cellulosic fibre.
The steps are straightforward, at least in principle. Certified wood chips (mostly eucalyptus, beech, and spruce) are pulped into cellulose sheets. The sheets are dissolved in warm NMMO to form a clear, viscous solution. That solution is extruded through spinnerets into a water bath, where the fibre precipitates and hardens. The used solvent is then filtered, purified, and cycled back into the process. Almost nothing goes to waste.
After spinning, the raw fibre is cut, baled, and shipped to spinners who turn it into yarn. Portuguese mills then knit or weave the yarn into fabric, dye and finish it, and ship it to garment factories. The finishing stage matters as much for Tencel as it does for cotton. Weak scouring or aggressive dyeing can dull the natural sheen and reduce drape. We've observed that mills who dye at yarn stage rather than piece stage tend to preserve the visual quality of Tencel more consistently.
Why the solvent loop matters: conventional viscose production releases carbon disulfide and other chemistry into wastewater at meaningful levels. Tencel's closed loop keeps solvent inside the system. For brands making sustainability claims, that difference is legally material. It's also the reason Tencel qualifies as a "preferred fibre" under Textile Exchange criteria, while generic viscose usually does not.
Citation Capsule: Tencel is produced through a patented closed-loop lyocell process that dissolves FSC-certified wood pulp in NMMO solvent, then recovers 99.5% of that solvent for reuse across production cycles. The process eliminates the toxic carbon disulfide emissions typical of conventional viscose manufacturing (Lenzing AG, 2024).
The role of FSC and PEFC certification
Every Tencel fibre carries chain-of-custody documentation from the forest to the mill. FSC and PEFC certifications verify that the trees were harvested from responsibly managed forests, with no clear-cutting of primary forest and controlled replanting cycles. This traceability is what allows Tencel garments to make credible sustainability claims under EU Green Claims regulation, which is tightening through 2026.
Is Tencel the Same as Lyocell?
Tencel and lyocell are related but not identical. Lyocell is the generic fibre category defined under ISO 2076; Tencel is Lenzing AG's registered trademark for its specific lyocell product line. Lenzing controlled roughly 80% of global branded lyocell capacity in 2024 (Textile Exchange, 2024), which is why Tencel is often used as a shorthand for the whole category.
The practical differences matter for sourcing. Generic lyocell can be produced by any mill using the closed-loop process, but the level of solvent recovery, wood certification, and quality control varies. Tencel-branded fibre carries a guarantee: Lenzing's process, Lenzing's chain of custody, Lenzing's audit trail. That guarantee has a cost, typically 10 to 20% above generic lyocell at the yarn level.
For most Portuguese factories, that premium is worth paying when a brand wants to make explicit sustainability claims on hangtags or product pages. Regulators in the EU are increasingly strict about unverified environmental claims, and Tencel's branded documentation reduces legal risk. For brands that want the fibre performance without the marketing angle, generic lyocell is a valid choice.
When to specify "Tencel" vs "lyocell" on a tech pack
We've found that founders who specify "Tencel Lyocell" on their tech pack, rather than "lyocell", get more consistent yarn sourcing and fewer questions from the factory. Portuguese mills either stock Tencel branded yarn or don't; specifying it forces a clear yes/no. A vague "lyocell" spec leads to substitution with cheaper alternatives that may or may not deliver the same drape and colour. Small detail, real impact.
What Are the Properties of Tencel Fabric?
Tencel's core properties come from the way its fibre cross-section holds and releases moisture. The fibre wicks moisture roughly 50% more efficiently than cotton and dries measurably faster, which is why athleisure and performance brands often specify it (Lenzing AG, 2024). Beyond moisture management, the fibre is soft, biodegradable in soil and marine conditions, and colour-holds well through repeated washes.
The key physical properties fashion founders care about:
- Softness: natural silk-like hand, no chemical softeners needed
- Drape: fluid, almost liquid on-body, ideal for dresses and blouses
- Moisture-wicking: roughly 50% more efficient than cotton
- Wet strength: retains around 85% of dry strength when wet
- Breathability: highly breathable, temperature-regulating
- Biodegradability: decomposes within months in soil and marine conditions
- Wrinkle resistance: moderate, better than pure linen, weaker than polyester blends
- Colour depth: dyes deeply and evenly, with strong colour retention
The property most founders underestimate is drape. Tencel has a hand and flow closer to silk than to cotton. That means garments cut for cotton will not sit the same way when the fabric is switched to Tencel. Patterns often need adjustment. Structured tailoring rarely works with 100% Tencel because the fabric wants to move.
Isn't more softness always better? Not for every silhouette. A boxy oversized hoodie in 100% Tencel french terry loses the structure that makes the silhouette work. In our experience, Tencel shines in womenswear dresses, drapey blouses, wide-leg trousers, and athleisure that benefits from moisture management. It's a poor fit for tailored jackets and structured menswear.
Citation Capsule: Tencel fibres wick moisture roughly 50% more efficiently than cotton and retain around 85% of their dry strength when wet, according to Lenzing operational testing. This wet-strength property is why lyocell clothing survives repeated washing better than viscose, and why Tencel dominates in dresses, blouses, and performance layers where cotton would sag (Lenzing AG, 2024).
What Garments Are Made with Tencel?
Tencel garments cluster in three main categories: womenswear (dresses, blouses, skirts), athleisure (tees, joggers, sports bras with moisture management), and premium loungewear (drapey knits, robes, pyjamas). Roughly 65% of Tencel-branded fibre sold in Europe in 2024 went into womenswear applications (Textile Exchange, 2024), with athleisure the fastest-growing sub-segment.
Specific garment applications by fabric type:
- Tencel woven (150-200 GSM): dresses, blouses, shirts, wide-leg trousers, midi skirts
- Tencel jersey knit (140-200 GSM): drapey tees, dresses, athleisure tops, lightweight loungewear
- Tencel french terry blend (240-320 GSM): premium hoodies with silky hand, athleisure sets, robes
- Tencel-cotton blend (180-260 GSM): everyday tees, elevated basics, sustainable capsules
- Tencel-elastane blend (180-220 GSM): activewear leggings, sports bras, moisture-wicking layers
Emerging brand founders often overlook Tencel's role in athleisure. The fibre wicks moisture better than cotton, dries faster, and doesn't hold body odour the way polyester does. That combination is why sustainable performance brands increasingly specify Tencel-elastane blends in leggings and layering pieces. It's a category with real growth in Portuguese production over the last two years.
Womenswear remains the biggest application, though. A 160 GSM Tencel woven dress drapes better than any comparable cotton fabric, holds colour depth beautifully, and photographs well in both natural and studio light. For brands building a womenswear line in Portugal, Tencel is often the fabric that unlocks the on-body look their design team wants.

What GSM Ranges Are Tencel Fabrics Available In?
Tencel fabrics span a wide GSM range, from around 100 GSM for lightweight blouses and shirting up to roughly 320 GSM for Tencel-blended french terry. The 140 to 200 GSM band represents the majority of tencel wear production in Europe, particularly for the dress and blouse categories that account for most brand launches (EURATEX, 2025).
Different weight tiers serve different silhouettes. Choosing the wrong tier is a common first-collection mistake. A 130 GSM Tencel dress feels close to sheer in flat lighting. A 280 GSM Tencel french terry hoodie is heavier than most founders expect. Getting the weight right is a first-order decision, same as with cotton.
Light Tencel (100-140 GSM)
Light Tencel is used for summer blouses, camisoles, sheer shirting, layering pieces, and lightweight kimonos. It feels almost slippery on-body and drapes like silk. This tier is not typically used for structured pieces because it lacks the body to hold a shape.
Standard Tencel (150-200 GSM)
This is the default womenswear weight and the most commonly ordered tier at Portuguese factories carrying lyocell. It works for dresses, midi skirts, structured blouses, wide-leg trousers, and lightweight jackets with unstructured shoulders. Most first-time Tencel collections launch here.
Mid-weight Tencel (200-260 GSM)
Mid-weight Tencel is used for elevated tees, jersey dresses, athleisure tops, and light loungewear pieces. It has more body than the standard tier, holds shape better through washing, and works well in Tencel-cotton blends. Sustainable performance brands often land in this range for their day-to-day pieces.
Heavier Tencel blends (260-320 GSM)
This tier is where Tencel-french terry blends live. The fabric is soft, has a distinctive silky hand, and holds shape well after multiple washes. It's used for premium hoodies, structured joggers with drape, and robes. This range requires blends: pure Tencel above 260 GSM is uncommon because the fabric loses its characteristic drape.
Citation Capsule: Tencel fabric GSM ranges from 100 (sheer blouses) to 320 (Tencel-cotton french terry blends), with the 150 to 200 GSM standard tier accounting for most European womenswear production. Above 260 GSM, Tencel is almost always blended with cotton or modal because pure Tencel at heavier weights loses its characteristic drape (EURATEX, 2025).
What Does Tencel Cost per Meter in Portugal?
Tencel fabric prices in Portugal in 2026 range from €7 per meter for standard cotton-Tencel blends at moderate GSM, up to €17 per meter for heavier Tencel french terry blends with certification. Composition, GSM, and Lenzing licensing are the three largest cost drivers, together explaining roughly 80% of price variance across Portuguese suppliers (ATP, 2025).
Understanding these tiers helps founders budget realistically during tech pack preparation, and avoid the "why is this so much more than cotton?" moment during first quotes. Tencel is a premium cellulosic, and pricing reflects both the licensed yarn cost and the lower production volumes at Portuguese mills.
Composition drives base cost
100% Tencel is the most expensive standard option because the yarn commands a licensing premium and comes exclusively from Lenzing. Tencel-cotton blends (60/40 or 50/50) reduce the price by 20 to 30% while keeping most of the drape and moisture properties. Tencel-elastane blends add cost for the elastane content and precision knitting. Certified organic combinations (Tencel + GOTS cotton) sit at the top of the price range.
GSM adds cost proportionally
Doubling the GSM roughly doubles the yarn consumption. A 280 GSM Tencel french terry uses about 1.6 times the yarn of a 180 GSM Tencel jersey, which typically increases the fabric price by 40 to 60%. Yarn cost dominates the total for Tencel more than it does for cotton, because the base fibre is more expensive.
Certifications and traceability add measurable premium
Tencel already carries FSC/PEFC and EU Ecolabel by default, so those don't add extra. Combining Tencel with GOTS-certified cotton adds €1 to €3 per meter over conventional cotton blends. OEKO-TEX Standard 100 is standard at most Portuguese mills carrying Tencel. GRS certification (for any recycled content in the blend) adds €0.50 to €1.50 per meter.
Practical planning: for a Tencel dress using 1.8 meters of 160 GSM Tencel woven, fabric cost lands at €18 to €29 per garment. A Tencel-cotton blend hoodie using 1.7 meters of 280 GSM french terry blend costs €19 to €29 in fabric alone. That's roughly 40 to 60% more than the same garment in standard cotton, and this fabric-only difference is often what surprises first-time founders costing a sustainable capsule.

Tencel vs Cotton vs Modal: How to Choose?
The most common founder question is whether to use Tencel, cotton, or modal for a specific silhouette. The short answer: cotton for structure and value, modal for softness and everyday knits, Tencel for drape, sustainability claims, and premium hand. Roughly 30% of European sustainable-positioning brands specified Tencel or lyocell as their primary fibre in 2024-2025 (Textile Exchange, 2024).
The three fibres differ in three important ways. Cotton is natural, familiar, and cheapest, but wrinkles easily and doesn't drape like the cellulosics. Modal (which Lenzing also produces under the Tencel brand) is softer than cotton and drapes better, but has lower wet strength than lyocell. Tencel Lyocell has the best drape and moisture management of the three, the highest wet strength among cellulosics, and the strongest environmental profile, at meaningfully higher cost.
| Attribute | Tencel Lyocell | Cotton | Modal |
|---|---|---|---|
| Fibre source | FSC eucalyptus, beech, spruce pulp | Cotton plant, natural | Beech tree pulp |
| Softness | High, silk-like | Moderate | Very high |
| Drape | Excellent, fluid | Moderate | Good |
| Moisture wicking | Excellent (~50% better than cotton) | Absorbent, slow to dry | Good |
| Wet strength | High (~85% of dry) | Moderate | Lower than Tencel |
| Biodegradability | Full, marine and soil | Full | Full |
| Environmental profile | Closed-loop, 99.5% solvent reuse | Water-intensive if conventional | Between viscose and Tencel |
| Cost per meter (Portuguese, 180-200 GSM) | €9 to €14 | €4 to €9 | €7 to €11 |
| Best for | Dresses, blouses, athleisure, drapey knits | Basics, hoodies, structured pieces | Everyday tees, soft loungewear |

When to choose which: we consistently see three patterns across our factory group. Brands building a drapey womenswear line or sustainable premium capsule go with Tencel. Brands prioritising cost, structure, and familiarity (streetwear, basics, structured menswear) stay with cotton. Brands that want silky next-to-skin comfort in high-volume everyday tees split toward modal. Increasingly, we see brands blending: 60/40 cotton-Tencel is the single most-requested "sustainable upgrade" blend at Portuguese mills right now.
Citation Capsule: Tencel Lyocell outperforms cotton and modal on drape, moisture wicking, and wet strength, at roughly 60 to 90% higher fabric cost. Around 30% of European sustainable-positioning brands specified Tencel or generic lyocell as their primary fibre in 2024-2025, with cotton-Tencel blends being the most commonly requested "sustainable upgrade" at Portuguese mills (Textile Exchange, 2024).
How Do Portuguese Factories Work with Tencel?
Portuguese factories produce some of Europe's most respected lyocell clothing, though only a subset of the cluster carries Tencel yarn as a standard offering. Roughly 15% of the 80 documented factories in our group stock Tencel yarn regularly, with another 20% able to book it against confirmed orders (PCF factory documentation, 2026). Fabric mills in the Ave Valley and Vale do Cávado handle most Tencel knitting and weaving for the region.
Portuguese Tencel production follows a specific sequence. Yarn is booked from Lenzing-authorised spinners (typically 3 to 5 weeks lead time). The mill knits or weaves the fabric, dyes and finishes it (7 to 12 days). The fabric ships to a CMT factory for garment assembly. Total lead time from order to shipped tencel garments typically runs 8 to 11 weeks for standard blends, and 10 to 13 weeks for 100% Tencel with certified organic cotton stacks. That's 2 to 3 weeks longer than standard cotton, driven almost entirely by yarn booking.
Production-side observation: across 2024-2026 production runs coordinated through our factory group, the average sample-to-shipment timeline for Tencel-cotton blend dresses at 180 GSM was 61 days. For 100% Tencel woven blouses at 130 GSM with GOTS-certified interlining, the average was 74 days. Fabric MOQ at the mill level ran 300 to 500 meters typical, and garment MOQ at factories carrying Tencel started at 200 units per style at most producers.
Sample rounds for Tencel are comparable to cotton, at 1 to 3 iterations with a clean tech pack. In our experience, the risk isn't the fabric or the factory. It's the yarn booking window. Founders who confirm production two months out and expect standard cotton lead times get frustrated. Founders who plan a longer runway and route the order through a factory that already stocks Tencel land close to on-time.
Citation Capsule: Roughly 15% of the 80 documented Portuguese factories in the PCF group stock Tencel yarn as a standard offering. Fabric MOQ at Portuguese mills for Tencel typically runs 300 to 500 meters, and garment MOQ starts at 200 units per style. Total lead time from order to shipped garments runs 8 to 11 weeks for standard blends, 2 to 3 weeks longer than standard cotton, driven by yarn booking (ATP, 2025).

Conclusion: What This Means for Your Brand
The practical takeaway across the sections above: match tencel to the product categories where its properties actually matter, specify it clearly on the tech pack (name the branded fibre or exact composition), and route production to a Portuguese factory in the subset that stocks the yarn or has the finishing lines built for it.
Get the spec right and the fabric becomes a repeatable, reliable choice. Leave it vague and you invite substitution, wash-cycle problems, and margin surprises.

Frequently Asked Questions
What is Tencel fabric made from?
Tencel is made from FSC and PEFC-certified wood pulp, mostly eucalyptus, beech, and spruce, dissolved in a non-toxic NMMO solvent through a closed-loop process. Roughly 99.5% of the solvent is recovered and reused, giving Tencel one of the strongest environmental profiles of any cellulosic fibre (Lenzing AG, 2024).
Is Tencel better than cotton?
Not universally. Tencel drapes better, wicks moisture roughly 50% more efficiently than cotton, and has a stronger environmental profile. Cotton is cheaper, more structured, and better for basics, hoodies, and menswear tailoring. Around 30% of European sustainable-positioning brands specified Tencel or lyocell as their primary fibre in 2024-2025 (Textile Exchange, 2024).
Is Tencel the same as lyocell?
All Tencel is lyocell, but not all lyocell is Tencel. Lyocell is the generic fibre category under ISO 2076. Tencel is Lenzing AG's branded lyocell product with chain-of-custody, FSC certification, and audit documentation. Lenzing controlled roughly 80% of global branded lyocell capacity in 2024 (Textile Exchange, 2024).
How much does Tencel fabric cost per meter in Portugal?
Tencel-cotton blend at 200 GSM runs €7 to €11 per meter at Portuguese mills. 100% Tencel jersey at 180 GSM costs €9 to €14, and Tencel french terry blends at 280 GSM reach €11 to €17 (ATP, 2025). A typical Tencel dress uses roughly 1.8 meters of fabric.
What is the minimum order for Tencel production in Portugal?
MOQs at documented Portuguese factories carrying Tencel typically start at 200 units per style, with fabric-level MOQs at 300 to 500 meters at the mill. Roughly 15% of our 80 documented factories stock Tencel yarn regularly; another 20% can book it against confirmed orders with a 2 to 3 week additional lead time.
Does Tencel shrink?
Tencel shrinks less than cotton after correct finishing, typically 2 to 4% after the first wash if the fabric was properly compacted at the mill. Poorly finished Tencel can shrink 5 to 8% and lose its drape. In our experience, mills that finish yarn-dyed Tencel at a controlled tension preserve both dimensional stability and the natural sheen best.
Is Tencel biodegradable?
Yes. Tencel is fully biodegradable in both soil and marine environments, typically decomposing within a few months under standard composting conditions. This is one of the reasons the fibre carries EU Ecolabel and Textile Exchange "preferred fibre" status. Blends with synthetic fibres (elastane, polyester) reduce biodegradability proportionally.
Can Tencel be blended with other fibres?
Yes, and blending is the most common way it's produced. Standard blends include Tencel-cotton (60/40 or 50/50), Tencel-modal, Tencel-wool for winter pieces, and Tencel-elastane (typically 95/5 or 92/8) for athleisure. Portuguese mills commonly stock Tencel-cotton and Tencel-elastane blends; other blends are booked to order.
