TENCEL vs Lyocell: What Is the Difference?
Lyocell is a generic fibre name for a regenerated cellulose fibre made by dissolving wood pulp in a solvent and spinning it into fibres. TENCEL is a brand name owned by Lenzing for its own lyocell and modal fibres, such as TENCEL Lyocell and TENCEL Modal. So all TENCEL Lyocell is lyocell, but not all lyocell is TENCEL. When a supplier says TENCEL lyocell fabric, the correct next question is whether the fibre is actually the Lenzing brand and whether it can be documented.
This distinction matters for labelling and for claims. A garment label should show the fibre name, which is lyocell, while the brand can appear as additional information when the supplier is licensed to use it. Ask for the licence or traceability documents from the fibre owner or its authorised chain before using the brand name in marketing.
Lyocell sits in the same family as viscose and modal, and shares some, but not all, of their behaviour. The rest of this guide explains where it differs.
How TENCEL Lyocell Fabric Is Made
Lyocell uses a direct dissolving method that is simpler than the viscose route. Wood pulp is dissolved in an organic solvent without first being chemically converted into another compound, and the solution is then spun into fibres in a bath that sets them. The solvent is washed out and, in a well-run plant, is typically recovered and reused in a closed loop. This is where the phrase closed-loop process comes from.
From wood pulp to lyocell yarn
- 1Wood pulpCellulose is separated from wood and prepared for dissolving.
- 2DissolvingThe pulp is dissolved in an organic solvent to make a spinning solution.
- 3SpinningThe solution is extruded through fine nozzles into a bath that forms fibres.
- 4Solvent recoveryThe solvent is washed out, and typically recovered and reused.
- 5Yarn and fabricFibres are cut or kept as filament, spun into yarn, and woven or knitted.
Simplified overview. Individual producers and plants differ, and a closed-loop process does not by itself make the whole garment low impact.
Closed-loop solvent recovery is a genuine point of difference compared with conventional viscose, but it is only one part of the footprint. Wood sourcing, energy use, dyeing and finishing, shipping and the garment's lifespan all matter too.
TENCEL Lyocell Fabric Properties
Lyocell fibres are smooth, strong and highly absorbent. They combine the cool, fluid feel of viscose with better wet strength, so lyocell can be machine washed more confidently than viscose. The table summarises the properties that matter for clothing.
TENCEL lyocell fabric properties
| Property | Typical behaviour | What it means for a garment |
|---|---|---|
| Softness and hand | Smooth, cool, sometimes silky | Comfortable next to skin; premium feel |
| Drape | Fluid and heavy for its weight | Soft shirts, dresses and relaxed trousers that hang well |
| Moisture handling | Absorbs moisture into the fibre and releases it readily | Comfortable in warm conditions; fabric can feel cool |
| Wet strength | Good; much better than standard viscose | More tolerant of washing, though gentle care helps |
| Fibrillation | Fibres can split into fine fibrils on the surface when wet and abraded | Can create a peach-skin surface, or unwanted fuzzing if uncontrolled |
| Crease behaviour | Creases moderately; recovers better when blended with cotton or polyester | Often needs finishing or blending for casualwear |
| Colour | Takes dye well, with good depth | Rich colours and smooth prints |
General characteristics. Yarn, construction and finish change any row.
Fibrillation is the property that makes lyocell unusual. When the fibre is wet and rubbed, tiny filaments lift from the surface. Mills use that deliberately to create a soft peach skin finish, and then control it with enzyme treatments so the fabric does not keep fuzzing. A poorly finished lyocell fabric can pill or look worn early, so ask how the finish is controlled.
Where TENCEL Lyocell Fabric Is Used in Clothing
TENCEL lyocell fabric is used wherever a soft, fluid and cool-feeling cloth adds value. Because it is strong enough when wet to be machine washed with reasonable confidence, it has moved from occasional luxury uses into mainstream casualwear, particularly in blends. It is rarely chosen for rugged, abrasion-heavy products, where cotton or polyester blends are more durable and cheaper.
- Lightweight denim for jeans, shirts, shorts and dresses, where lyocell adds softness and drape.
- Casual woven shirts, shirt-dresses and relaxed trousers.
- Soft knit tops and loungewear, often blended with cotton or elastane.
- Linings and scarves, where a smooth surface and cool feel are valuable.
- Bedding and home textiles, which is outside the scope of clothing manufacturing but shows how widely the fibre is used.
Think of lyocell as a way to change the character of a cloth, not as a drop-in replacement. A small lyocell share in a cotton fabric changes the hand noticeably, while a high share makes the fabric more fluid, more sensitive to finishing and usually more expensive.
TENCEL Lyocell vs Viscose vs Modal vs Cotton
A comparison across the cellulosic family makes the choice clearer. Lyocell, modal and viscose are close relatives, and cotton is the benchmark that most brands start from. The ratings below are indicative only.

Indicative ratings based on typical fabric/process characteristics, not laboratory results.
Lyocell leads on wet strength and moisture management among the regenerated fibres, but it can cost more and it demands careful finishing. If your priority is a very soft knit tee, modal may be the more common choice. If your priority is a fluid woven shirt, lyocell is a strong candidate.
TENCEL Lyocell Denim and Cotton Blends
Blending lyocell with cotton is one of the main ways it enters everyday clothing. In denim, lyocell-cotton blends give a softer, smoother handfeel and a more fluid drape than rigid 100 per cent cotton denim, which is why they are popular in lighter weight jeans, shirts, dresses and relaxed trousers. The blend can also feel cooler against the skin.
Common lyocell blends in clothing
| Blend | Character | Typical use |
|---|---|---|
| Lyocell-cotton denim | Soft, fluid denim; lighter weights drape well | Relaxed jeans, dresses, shirts, jackets |
| Lyocell-cotton woven | Smooth and cool with more body than pure lyocell | Casual shirts, trousers, shirt-dresses |
| Lyocell-elastane | Stretch and recovery in a fluid fabric | Fitted trousers and tops, lightweight denim |
| Lyocell-linen | Softens linen's texture while keeping a relaxed look | Summer shirts and trousers |
Ask the mill for the exact blend proportions, as the majority fibre sets the character of the cloth.
Lyocell denim behaves differently in dyeing and washing, so wash recipes developed on rigid cotton do not transfer automatically. Our guide to denim fabric composition and the overview of types of denim fabric help you place a lyocell blend in the wider range. Availability depends on the mill and the minimum quantities, so ask early.
TENCEL Lyocell Fabric Care, Fibrillation and Shrinkage
TENCEL lyocell fabric usually tolerates machine washing better than viscose, but care instructions still need to come from testing. Cool to moderate temperatures, gentle spin speeds and avoiding aggressive tumble drying help preserve the surface and limit shrinkage.
- Wash inside out on a gentle or cool cycle to reduce surface abrasion.
- Avoid harsh detergents and bleach, which can roughen the fibre.
- Dry flat or tumble on low heat; high heat can harden the hand and increase shrinkage.
- Iron on a moderate setting while slightly damp, or steam.
Request shrinkage, colour fastness and pilling tests on the actual bulk fabric. Our garment testing guide lists what to request. If the fabric has a peach skin finish, ask for a pilling test after several washes, not just the initial result.
Sustainability: What to Ask About TENCEL Lyocell Fabric
Lyocell is often marketed as a sustainable fibre, and the closed-loop process is a good reason to take it seriously. A balanced view recognises that sustainability depends on the whole chain: pulp sourcing, the energy mix at the fibre plant, dyeing, finishing and how long the garment lasts. The fibre's own claims do not extend automatically to the finished fabric or garment.
Questions to ask a supplier about lyocell
| Topic | Question | Evidence to request |
|---|---|---|
| Fibre identity | Is it generic lyocell or branded TENCEL Lyocell? | Brand licence or traceability from the fibre owner |
| Wood source | Where is the pulp from, and is forestry certified? | FSC or PEFC chain-of-custody documents |
| Process | Is the solvent recovered in a closed loop? | Producer documentation, not marketing language |
| Fabric stage | How are dyeing and finishing managed? | Mill certifications, such as OEKO-TEX Standard 100 |
| Claims | What will you say on the label and website? | Evidence for each specific claim |
See our guide to sustainable denim suppliers for how this applies to denim.
Other Cellulosic Fibres: Where Cupro Fits
Lyocell, modal and viscose are not the only regenerated cellulose fibres. Cupro is another, made from cotton linter, the short fibres left on cottonseed after ginning, and it is sometimes used for linings and silky fabrics. It is a specialist material with its own supply chain, and it is rarely part of everyday casualwear. If you need it, treat it as a separate sourcing question and ask for the same fibre documentation you would ask for with lyocell.
How to Specify a Lyocell Blend
The steps below help you brief a factory or mill on a lyocell fabric in a way that can be quoted, sampled and tested consistently. Each step turns a vague wish for something soft and drapey into something checkable.
Specifying a lyocell blend
- 1Define the end productName the garment, the drape you want and the price point.
- 2Choose the blendState the fibre percentages, for example lyocell and cotton, and any elastane.
- 3Set weight and constructionGive GSM, weave or knit, and finish such as peach skin or washed.
- 4Ask for documentsRequest fibre origin, brand licence if relevant, and mill certifications.
- 5Sample and wash-testWash the sample several times and check shrinkage, pilling and colour.
Lyocell fabric brief checklist
- Fibre content and blend ratio, with tolerance
- Whether TENCEL branded fibre is required, and proof if so
- Fabric weight in GSM and the construction
- Finish: peach skin, enzyme wash, resin or none
- Shrinkage, pilling and colour fastness targets
- Care label wording agreed after testing
How Ruhrose Approaches Lyocell Blends
Ruhrose develops hoodies, jersey, denim and woven casualwear for UK buyers, with production in Bangladesh. Lyocell-cotton blends in denim and soft woven casualwear, including drapey shirts and trousers, are a legitimate thing to discuss, though availability depends on the mill and cannot be promised in advance. We would ask for your target handfeel, weight and price, source suitable swatches, and sample before any bulk commitment. Specialist technical or performance cellulosics sit outside our core range.
