Viscose is a regenerated cellulose fibre, a type of rayon, made from plant cellulose (usually wood pulp) that gets chemically dissolved and then spun back into filaments. That chemical journey means it sits between natural and synthetic: the raw material is plant-based, but the processing is industrial. You’ll find it in dresses, blouses, linings and curtains, prized for its soft, silky feel and fluid drape.
TL;DR:
- Modal usually shrinks less than standard viscose, while high wet modulus rayon holds its shape better; lyocell uses a separate solvent process.
- Standard viscose weakens when wet, so check the sewn in care label; use cool water, avoid tumble drying, and reshape the garment while damp.
- Cotton is generally easier to wash and stronger when wet, while polyester resists abrasion and wrinkles; viscose feels softer and drapes more fluidly.
- A viscose label does not reveal forest sourcing or mill chemical controls; seek pulp traceability, recognized forestry certification, supplier disclosure, and independent mill standards.

Viscose, rayon and its relatives: what the labels mean
If you’ve ever checked a garment label and seen “viscose” on one dress and “rayon” on another that feels almost identical, you’re not imagining it. Both terms often describe the same family of fibre, and the difference is mostly geography rather than chemistry.
In the UK and much of Europe, “viscose” is the standard term you’ll see on care labels and in shops. In the United States, “rayon” is more common, and it can refer to the same regenerated cellulose fibre or to a close relative made with a slightly different process. The Cambridge Dictionary defines viscose as a man-made cellulosic fibre made from wood pulp, often described as silk-like because of its smoothness and drape, which is a fair summary of why shoppers reach for it.
Beyond the basic viscose versus rayon naming split, a few related fibres show up often enough that it’s worth knowing how they differ:
- Standard viscose: the most common form, soft and fluid but prone to weakening when wet.
- High-wet-modulus (HWM) rayon: a stronger, more durable variant made with adjustments to the viscose process, better suited to garments that need to hold shape.
- Modal: a type of HWM rayon typically made from beech pulp, known for extra softness and better shrink resistance than standard viscose.
- Lyocell: a separate regenerated cellulose fibre made with a different solvent process, generally considered to have lower chemical intensity than conventional viscose.
The practical takeaway for anyone reading a label: “viscose” tells you the fibre family, not the specific manufacturing route or its environmental footprint. A dress labelled viscose and one labelled modal can behave quite differently in the wash, even though both started life as wood pulp. High-wet-modulus viscose, for instance, resists the sagging and shrinkage that plague standard viscose, which is why some brands use it for fitted knitwear rather than loose, draped pieces.
Manufacturers also blend these fibres with cotton, polyester or elastane to borrow strengths from each, so a single “viscose blend” garment might carry very different care needs from a pure viscose one. That’s one reason the sewn-in label matters more than the fibre name alone. We’ll come back to that later.
How is viscose made? The process from wood pulp to fabric
The word “viscose” actually describes a step in the manufacturing process, not just the finished fibre. At one stage, the cellulose is turned into a thick, honey-like liquid, a “viscous” solution, which gets forced through tiny holes to form threads. That’s where the name comes from.
The conventional route from tree to textile runs through several distinct stages:
- Pulping: wood (often from fast-growing species like eucalyptus, pine or bamboo) is broken down to extract cellulose, the structural material in plant cell walls.
- Alkaline treatment: the pulp is treated with sodium hydroxide, which prepares the cellulose for the next chemical step.
- Xanthation: carbon disulfide is added, converting the treated cellulose into a compound called cellulose xanthate.
- Dissolving: the cellulose xanthate is dissolved into a viscous, syrup-like solution, the viscose itself.
- Filtering and ripening: the solution is filtered to remove impurities and left to mature to the right consistency for spinning.
- Extrusion: the viscose is forced through spinnerets (devices studded with tiny holes) into an acidic bath.
- Regeneration: the acid bath converts the dissolved cellulose back into solid cellulose filaments, chemically similar to the original wood pulp.
- Washing, drying and spinning: the filaments are washed to remove residual chemicals, dried, then either cut into short fibres for spinning into yarn or kept as continuous filament, before being woven or knitted into fabric.
What’s notable is that the finished fibre ends up with the same basic molecular structure as the cellulose it started from. The manufacturing process temporarily converts it into a soluble chemical form purely to make it spinnable, then regenerates it back. That’s the technical reason viscose is often called “regenerated cellulose” rather than a true synthetic.
This conventional sequence isn’t the only way to turn cellulose into fibre. Two alternative routes matter for anyone trying to understand the wider fabric landscape. The cuprammonium process, an older and now much less common method, dissolves cellulose using a copper-ammonia solution instead of carbon disulfide, producing a very fine, silk-like filament historically used in linings. Lyocell, by contrast, uses a different solvent system in what’s generally described as a more contained process, and several assessments point to it carrying lower chemical intensity than the conventional viscose route, which is part of why it’s gained ground as an alternative.
The chemical steps involving sodium hydroxide and carbon disulfide are also where environmental and worker-safety concerns concentrate, something documented in technical industry coverage. Carbon disulfide exposure and the treatment of wastewater from viscose mills have been long-standing points of scrutiny in the sector, which is worth keeping in mind before assuming “plant-based” automatically means low-impact.
How viscose feels and performs compared with other fabrics
Pick up a viscose dress and the first thing you’ll notice is how it moves. It has a fluid, almost liquid drape that clings and flows rather than holding a stiff shape, closer to silk than to cotton in the way it falls. The fibre is also highly absorbent, which is why viscose can feel cool and comfortable against skin in warm weather, though it absorbs moisture rather than wicking it away quickly.
That same absorbency is behind its biggest drawback. Viscose loses a significant amount of its strength when wet, which is why it’s prone to stretch out of shape, creasing deeply and shrinking if washed carelessly. It also pills and abrades more readily than sturdier synthetics under repeated wear.
According to Sewport’s fabric comparison, viscose is typically softer and more absorbent than polyester, but it’s often less durable and notably weaker when wet, with actual performance depending heavily on the yarn, weave and finish used.
Set against three fabrics shoppers compare it with most, the pattern looks like this:
- Polyester: generally stronger, faster-drying and more resistant to wrinkling and abrasion than viscose, but it lacks viscose’s breathability and soft, natural-feeling hand.
- Silk: shares a similar silky look and fluid drape, but silk commands a higher price and carries different care demands, usually dry-clean or careful hand-wash.
- Cotton: more breathable and generally easier to care for day-to-day, with better wet strength, though it doesn’t match viscose’s slinky drape or sheen.
A heavier viscose twill will resist creasing far better than a lightweight viscose chiffon, even though the fibre content is identical. If you’re deciding between a silk-look dress and a satin alternative, our piece on satin versus silk walks through how weave and fibre interact to produce very different handfeel.
Where you’ll find viscose and why it’s chosen so often
Designers reach for viscose because it solves a specific problem: it gives the look and movement of silk at a fraction of the cost, while taking dye and print exceptionally well.
Common places you’ll encounter it include:
- Dresses and blouses, where the drape creates flattering movement without the price tag of silk.
- Linings, where its smoothness improves comfort against skin inside jackets and coats.
- Knit tees and jersey tops, where blended viscose softens the feel of cotton-based fabric.
- Curtains and soft furnishings, where its sheen and fluidity suit draped, decorative fabric.
- Upholstery blends, where it’s combined with tougher fibres to balance comfort with durability.
Printability is a major reason viscose turns up so often in patterned clothing. The fibre absorbs dye readily and holds colour with good vibrancy, which is why so many floral and abstract print dresses use it as a base cloth. Blending matters here too: adding elastane improves stretch and recovery for fitted silhouettes, while blending with cotton or polyester can offset viscose’s tendency to lose shape, trading away a little drape for more resilience. A viscose-elastane jersey behaves nothing like a pure viscose crepe, even though both share the same core fibre.
Is viscose sustainable? Sourcing, chemicals and worker safety
Plant origin alone doesn’t settle the sustainability question, and that nuance matters more than most shopping guides let on.
Textile Exchange frames viscose as the most widely used man-made cellulosic fibre, and its central argument is that viscose should be judged as a supply-chain material, not simply by the fact that it starts life as a plant. A garment label reading “viscose” identifies the fibre family; it says nothing about which forest the wood pulp came from, whether that sourcing was traceable, or how the mill that processed it managed its chemicals and waste.
Two separate sets of concerns feed into that assessment. On the feedstock side, there’s a real risk of deforestation, biodiversity loss and damaging land-use change when wood pulp is sourced without scrutiny, a concern the Good On You material guide highlights alongside energy and water use across production. On the processing side, the chemicals involved, particularly carbon disulfide, along with the wastewater and emissions they generate, create documented risks for both surrounding communities and mill workers when controls are weak. The JRC technical reference from the European Commission lists viscose among the main textile fibre types and sets out how environmental impacts accumulate across fibre preparation, dyeing and finishing, not just at the growing stage.
Practical checks worth applying if you want to judge a specific brand’s claims rather than take “made from wood” at face value:
- Traceability: does the brand or supplier disclose where the wood pulp comes from?
- Credible forestry standards: look for recognised certification schemes like FSC rather than vague “sustainably sourced” wording.
- Supplier disclosure: brands that name their fibre or fabric suppliers are generally easier to verify than those that don’t.
- Independent standards: third-party frameworks that assess mill-level chemical management carry more weight than marketing copy alone.
Pro Tip: Treat “viscose” on a label as a starting point for questions, not an answer in itself, since the same fibre name can sit on products with very different sourcing behind them.
Caring for viscose: how to wash it without ruining it
Viscose rewards a bit of caution precisely because it loses strength when wet. The single most useful habit is checking the sewn-in label before you assume anything, since care needs vary between woven viscose, knitted viscose and blends.
- Read the label first: don’t assume all viscose garments are machine-washable just because the fibre is the same.
- Choose cool or cold water: a gentle cycle or hand wash reduces the stress that causes shrinking and stretching.
- Skip the tumble dryer: high heat is one of the fastest ways to shrink or distort viscose fibres.
- Reshape while damp: lay the garment flat and smooth it into shape before it dries fully, which helps prevent both shrinkage and stubborn creasing.
- Consider dry-cleaning for structured pieces: tailored viscose garments, or anything with linings, often hold their shape better with professional cleaning.
According to the MasterClass fabric guide, common precautions include cool or cold washing, gentle handling and reshaping while damp, specifically because viscose can shrink, crease and weaken when wet.
If a garment is already creased, a cool iron on the reverse side, or a gentle steam, usually sorts it out without stressing the fibres further.
Pro Tip: If a viscose piece starts pilling, trim the bobbles carefully with a fabric shaver rather than pulling at them, which can leave visible gaps in the weave.
Common myths about viscose, cleared up
Is viscose plastic? No. It’s regenerated cellulose, chemically processed plant material that’s dissolved and then converted back into its original molecular structure. Synthetic fibres like polyester, by contrast, are built from petroleum-derived polymers that never existed as plant cellulose in the first place, a distinction Segura makes clearly: calling viscose simply “natural” or “plastic” both miss the science.
Does the word “viscose” on a label mean the garment was responsibly made? Not on its own. As covered above, the fibre name tells you the family, not the forestry practices or mill standards behind it.
Finally, “rayon”, “viscose”, “modal” and “lyocell” aren’t interchangeable, even though they’re all regenerated cellulose fibres. They differ in manufacturing process and performance, so a label swap between them isn’t just marketing language, it reflects a genuinely different fabric.
Our take on choosing viscose-like fabrics
We look at fabric choice through comfort, drape and how a piece will actually behave after a few washes, not just how it photographs on a hanger. Viscose and its relatives earn their popularity honestly: that fluid movement is hard to fake with cheaper synthetics, and the softness against skin is widely appreciated.
Where we’d push back on the hype is the assumption that “plant-based” settles the sourcing question. It doesn’t, and we think shoppers deserve that honesty rather than a tidy “natural fibre” label.

FAQ
What are the downsides of viscose fabric?
Viscose loses a significant amount of strength when wet, making it prone to stretching, shrinking and creasing if washed carelessly. It also pills and wears faster than sturdier fabrics like polyester, and sourcing concerns around deforestation and mill chemicals mean its environmental profile varies by supplier.
Is viscose better than cotton?
Neither is strictly better: they suit different needs. Viscose offers a softer, silkier drape and takes dye and print more vividly, while cotton is generally more breathable, easier to wash and holds up better when wet.
Is viscose basically plastic?
No. Viscose is a regenerated cellulose fibre made from plant material that’s chemically dissolved and then converted back into cellulose, whereas plastic-based fibres like polyester are built from petroleum polymers that were never plant cellulose to begin with.
Is viscose a good material?
Viscose is widely valued for its soft, silk-like feel, strong drape and good absorbency, which is why it’s common in dresses, blouses and linings. Its performance depends heavily on the weave, finish and any blended fibres, and its environmental impact depends on how responsibly the wood pulp was sourced and processed.
