What Is Lyocell Fabric? Lyocell vs Tencel, Cotton and Viscose

The Short Answer

Lyocell is a smooth, strong, semi-synthetic fabric made from regenerated cellulose, usually from wood pulp. It belongs to the same family as viscose and modal, but it is made by a different route: the pulp is dissolved directly in a solvent that is recovered and reused, with no chemical conversion of the cellulose along the way. Tencel is a brand name owned by Lenzing AG and is the best-known lyocell on the market, which is why the two words are often used as if they meant the same thing.

For a brand, lyocell is a trade-off. It is stronger than viscose and modal, keeps much more of that strength when wet, drapes well and feels cool. It also costs more, can develop a fuzzy surface called fibrillation if the finish is not controlled, and branded fiber names come with documentation and licensing questions. This guide explains how lyocell is made, how it compares with Tencel, cotton, viscose and modal, whether it shrinks, and how to specify it for a factory.

What Is Lyocell Made Of?

Lyocell starts as dissolving pulp, a purified form of cellulose. The pulp usually comes from wood such as eucalyptus, beech, spruce or birch, and it can also come from bamboo or, in some newer fibers, partly from recycled cotton waste. The cellulose is dissolved and re-formed into fiber, so the structure of the original plant does not survive into the yarn.

That puts lyocell between the two usual fiber categories. The raw material is natural, but the fiber is manufactured. It is not a natural fiber like cotton or linen, and it is not an oil-based synthetic like polyester. The usual descriptions are semi-synthetic, man-made cellulosic or regenerated cellulose.

Lyocell vs Tencel: Are They the Same?

Not quite. The difference is between a fiber type and a brand.

The Tencel name dates from the first commercial lyocell, launched by the British company Courtaulds in the early 1990s. Lenzing acquired the business in 2004. So all Tencel Lyocell is lyocell, but not all lyocell is Tencel. When a mill offers "Tencel", ask whether it means the Lenzing fiber or generic lyocell, and ask for documentation. The price, the paperwork and what you are allowed to write on a hangtag all depend on the answer.

How Lyocell Is Made

The lyocell process is shorter than the viscose process and works differently:

Two points explain most of the fabric's behavior. First, the cellulose is dissolved without being turned into a different compound, which is the main difference from viscose and the reason carbon disulfide is not used. Second, the cellulose chains in the finished fiber are long and highly aligned along its length. That alignment gives lyocell its strength, and it is also the reason the fiber surface can split into fine fibrils when it is rubbed while wet.

Properties of Lyocell Fabric

Lyocell vs Cotton, Viscose, Modal and Polyester

Lyocell vs Cotton

Lyocell is smoother, drapes more and has a subtle sheen. Cotton has more body, a matte look and a drier hand. Both are absorbent and comfortable in warm weather. Cotton is more widely available, usually costs less and tolerates harsh laundering well. Lyocell is the stronger choice when the design depends on movement and a soft, cool surface. The two are often blended, especially in denim, shirting and jersey, to add softness and drape to a cotton base.

Lyocell vs Viscose

Both are regenerated cellulose, but lyocell is stronger, far more stable when wet and generally less prone to shrinking and distorting. Viscose usually costs less and is available in a wider range of printed and fashion wovens. Lyocell is the better fit for garments that will be washed often. Viscose can be enough for a dress or blouse washed occasionally. Our viscose fabric guide covers viscose, rayon and why viscose shrinks.

Lyocell vs Modal

Modal tends to feel softer and more fluid, which is why it is common in underwear, sleepwear and loungewear. Lyocell is stronger and has a cleaner, slightly crisper hand, which suits shirts, trousers, dresses and denim. Both hold up better in washing than regular viscose. Our modal fabric guide covers modal and micromodal in detail.

Lyocell vs Polyester

Polyester is an oil-based synthetic. It resists creasing, dries quickly, holds its shape and costs little, but it absorbs very little moisture and can feel warm. Lyocell feels cooler and more natural against the skin, but it costs more and needs more care in finishing. Lyocell-polyester blends trade some of that comfort for durability and easier care.

Common Lyocell Fabrics and Uses

Lyocell is a fiber, not a construction, so the name alone does not tell a factory what fabric you want. Common types include:

Whether the fabric is knitted or woven changes how the garment is cut, sewn and tested. The knit vs woven guide covers that choice.

Does Lyocell Shrink?

It can, but usually less than viscose. Lyocell is more stable when wet than regular viscose, and a properly finished lyocell fabric holds its dimensions reasonably well in gentle washing. Hot water, tumble drying and loose constructions can still cause shrinkage, and the first wash usually shows most of it.

The result depends on the construction, the finish and the care, so treat shrinkage as a specification item and not a fiber fact. Set a maximum dimensional change, name the test method and test the bulk fabric, not only the sample. A garment wash adds another variable, as our guide to enzyme and garment washing explains. The test logic in our pre-shrunk cotton guide applies here as well.

Care instructions should come from testing. In the US, a care label needs a reasonable basis under the FTC Care Labeling Rule. If the garment is meant to be machine washed and tumble dried, the fabric should be developed and tested for that.

What Is Fibrillation?

Fibrillation is the splitting of fine fibrils from the fiber surface when the fabric is rubbed while wet. It is the production issue most specific to lyocell.

It can work for or against a product. Mills use controlled fibrillation, followed by an enzyme treatment and tumbling, to produce the soft, slightly sueded peach-skin surface that many lyocell fabrics are known for. Uncontrolled fibrillation is a fault. It shows up after home washing as a fuzzy or matted surface, pilling, or a pale, frosted look on dark shades, most visibly along seams and creases.

There are three practical controls:

If a clean surface matters, say so in the specification. "Lyocell twill" on its own leaves the finish to the mill.

Is Lyocell Sustainable?

Lyocell has a stronger starting point than regular viscose, but the fiber name does not answer the question. The process avoids carbon disulfide and recovers the solvent in a closed loop, and the fiber is biodegradable under suitable conditions. The outcome still depends on the producer and on everything that happens after the fiber is made.

Useful questions for a mill include who produced the fiber, whether the pulp is traceable, and whether the finished fabric is certified to OEKO-TEX or another harmful-substance standard. If the product is positioned as organic, check how a lyocell blend fits the rules in our GOTS certification guide. Avoid broad claims such as "eco-friendly" unless you can substantiate them.

What Is Bamboo Lyocell?

Bamboo lyocell is lyocell made from bamboo pulp. Once the bamboo has been dissolved and re-formed, the result is regenerated cellulose, so it is not a bamboo fiber in the way that linen is a flax fiber. The FTC has taken repeated action against sellers of rayon textiles marketed as bamboo.

Do not label or advertise this fabric simply as "bamboo", and do not assume the mill's trade description is safe to reuse. Get the exact wording approved by a compliance adviser before labels and product pages are finished.

Common Production Issues With Lyocell

How to Specify Lyocell Fabric for a Factory

"Tencel shirt" is not a specification. A useful tech pack line covers:

Agree acceptance limits with the factory before bulk. Then write them into the order and check them at inspection, as covered in our guide to AQL sampling.

Labeling and Using the Tencel Name

Under the FTC's Textile Rules, rayon is the generic name for regenerated cellulose fiber, and the rules allow the term lyocell to be used as a generic description for fiber made by this direct solvent process. A brand name is not a generic fiber name, so a trademark such as Tencel does not replace the fiber content statement. Confirm the exact fiber wording, along with the care and country-of-origin details, with a compliance adviser before labels are printed.

TENCEL and LENZING are trademarks of Lenzing AG. If a brand wants to use those names on a hangtag or product page, it should check the brand owner's licensing and fabric certification requirements first, and it needs documentation that the fiber is genuine. Do not use a branded fiber name on the strength of a mill's verbal description.

Apparel sold in the US must also meet the flammability standard at 16 CFR Part 1610, so ask your adviser whether a light or brushed fabric needs testing. For duties, classification depends on the garment and its fiber content, and a lyocell garment may not fall under the same tariff line as its cotton version. Ask a customs broker to confirm this before you compare landed costs.

MOQ and Cost Factors

Lyocell programs depend on the fabric as much as the garment. Factors that affect minimums and cost include:

Actual minimums and prices vary by factory and quality, so they should be confirmed in a written quote. Comparing quotes only works when composition, fiber source, construction, GSM and finish are the same on each one.

Sourcing Lyocell Garments in Turkey

Turkey has a large weaving, knitting, denim, dyeing and finishing base serving apparel brands, and its garment manufacturers regularly produce shirts, dresses, jersey tops and denim. Which lyocell qualities a factory can source, whether the fiber is branded or generic, and whether fabric comes from stock or through a partner mill all vary by factory. Confirm them at the quote stage, along with documentation of the fiber source.

SourceBridge responds to a textile brief within 24 hours with options from 2–3 pre-vetted Turkish factories. The published starting point for textiles is 300 units per style. Samples typically take 7–14 days, plus 5–7 days for international courier, and production typically runs 4–8 weeks depending on product complexity, with a pre-shipment inspection against the approved sample before goods leave the factory. Our guides on how to find a clothing manufacturer and clothing manufacturers for startups cover the steps before and after the specification.

FAQ: Lyocell Fabric

What is lyocell fabric?

Lyocell is a smooth, strong semi-synthetic fabric made from regenerated cellulose, usually from wood pulp. The pulp is dissolved in a solvent that is recovered and reused, then re-formed into fiber. It is used for shirts, dresses, denim, T-shirts and bedding.

Is lyocell the same as Tencel?

Not exactly. Lyocell is the generic fiber name. Tencel is a trademark of Lenzing AG, used for its lyocell fibers and for some modal fibers. All Tencel Lyocell is lyocell, but lyocell from other producers is not Tencel.

Is lyocell a natural fiber?

No. Lyocell starts from natural cellulose, but that cellulose is dissolved and re-formed in an industrial process. It is usually called semi-synthetic or man-made cellulosic, and it is not an oil-based synthetic like polyester.

Does lyocell shrink?

It can, though usually less than viscose. Hot water, tumble drying and loose constructions increase the risk, and most shrinkage shows in the first wash. Set a maximum dimensional change and test the bulk fabric.

Is lyocell breathable?

Generally yes. Lyocell absorbs moisture readily and feels cool against the skin, so it is comfortable in warm weather. The weight and construction of the fabric matter as much as the fiber.

Is lyocell stretchy?

Not much on its own. Woven lyocell has little stretch unless elastane is added. Lyocell jersey has stretch from its knit structure, and it is often blended with elastane for better recovery.

Is lyocell better than cotton?

Neither is better in every case. Lyocell is smoother and drapes more, while cotton has more body, is more widely available and usually costs less. The right choice depends on the garment and how it will be washed.

Is lyocell sustainable?

It has a stronger starting point than regular viscose because the solvent is recovered and reused. Pulp sourcing, the fiber producer and fabric processing still matter. Ask for fiber producer documentation, and avoid broad environmental claims unless you can substantiate them.

What is fibrillation in lyocell?

Fibrillation is the splitting of fine fibrils from the fiber surface when lyocell is rubbed while wet. Controlled, it gives a soft peach-skin finish. Uncontrolled, it causes fuzz, pilling or a frosted look, so specify the surface and wash test before bulk.
