Viscose is a fabric made from plant cellulose, most often wood pulp, that has been chemically processed into a soft, breathable fiber. You’ll see it on clothing labels for dresses, blouses, and loungewear because it drapes like silk but costs far less. It’s sometimes called rayon (the more common term in North America), while viscose is the standard name in Europe. Despite coming from plants, it’s not a natural fabric in the way cotton or linen is. The wood pulp goes through extensive chemical processing to become a wearable fiber, placing viscose somewhere between natural and synthetic.
How Viscose Is Made
The process starts with wood pulp, usually from beech, eucalyptus, or pine trees. That pulp is soaked in a strong alkaline solution to break down the cellulose, then pressed, shredded, and aged. The critical step involves treating the cellulose with carbon disulfide, a reactive chemical that converts the material into a thick, honey-like liquid. That liquid is forced through tiny holes in a device called a spinneret, producing fine filaments that harden into fiber.
The entire process involves 13 steps from raw pulp to finished fiber, including filtering, degassing, washing, and cutting. It’s a far cry from simply harvesting and spinning a plant fiber the way you would with cotton. This heavy processing is why viscose is classified as a “regenerated cellulosic fiber,” meaning the original plant structure is completely dissolved and rebuilt into something new.
What Viscose Feels Like to Wear
Viscose has a smooth, cool hand feel that sits close to silk in terms of softness. It absorbs moisture well, with a moisture regain of about 11.5%, which means it pulls sweat away from your skin rather than trapping it the way polyester does. That absorption makes it feel cool and comfortable in warm weather.
The fabric’s biggest appeal in clothing is its drape. Viscose falls and flows rather than holding a stiff shape, which is why designers use it for wrap dresses, bias-cut skirts, wide-leg pants, and relaxed blouses. It can mimic some of silk’s visual qualities, especially in satin or voile weaves, without the price tag or the obviously shiny look of cheaper synthetics. Many brands use it for elevated basics and contemporary fashion lines where softness and movement matter more than structure.
Where You’ll Find It on Labels
Viscose shows up most often in:
- Dresses and blouses where fluid movement is the goal
- Linings inside jackets and coats, where its smoothness helps garments slide on easily
- Loungewear and casual tops where comfort against the skin is the priority
- Knit tees and ribbed tops that need softness without bulk
You’ll less commonly see it in structured outerwear, activewear, or anything designed for heavy-duty use, because its strengths are comfort and aesthetics rather than durability.
The Weak Spot: Water
Viscose has a well-known vulnerability. When wet, it loses about 60% of its tensile strength, a much larger drop than cotton experiences. This is why viscose garments can feel fragile during washing and why many carry “dry clean only” or “hand wash” labels.
Shrinkage is the other concern. Viscose typically shrinks 8 to 10% if washed carelessly, compared to 4 to 7% for cotton and just 1 to 3% for polyester. If you do wash viscose at home, use cold water, a gentle cycle, and lay the garment flat to dry. Wringing, twisting, or tumble drying on high heat will almost certainly damage the fabric or change the garment’s shape permanently. Keeping water temperature at or below 30°C helps minimize both shrinkage and fiber weakening.
Viscose vs. Modal vs. Lyocell
All three fabrics start from the same place: plant cellulose dissolved and reformed into fiber. The differences come down to how they’re processed, which changes the final fiber’s performance.
Modal uses a very similar chemical process to viscose, but the fibers are stretched after spinning to increase molecular alignment. This makes modal stronger, lighter, and finer. Practically, that means modal holds up better in the wash and can handle tumble drying without damage. If you’ve ever noticed a t-shirt label listing modal, that extra durability is the reason it was chosen over standard viscose.
Lyocell (often sold under the brand name Tencel) takes a different route entirely. Instead of carbon disulfide, the production uses a non-toxic organic solvent that can be filtered and recycled in a closed loop. This makes it significantly more environmentally friendly. The different process also produces a fiber with a more uniform internal structure, which improves moisture absorption and breathability beyond what standard viscose offers. Lyocell tends to be the most expensive of the three but also the most durable and eco-conscious.
Environmental Concerns
Viscose’s environmental footprint is complicated. The raw material is renewable (trees grow back), but the manufacturing process relies heavily on carbon disulfide, a chemical with a troubling history. Workers exposed to carbon disulfide in viscose factories have experienced neurological disease and increased rates of cardiovascular illness, a pattern documented as far back as the early 20th century and continuing for decades. Research published in the American Journal of Public Health described how reports of these harms were “intentionally ignored, minimized, and buried” by the industry.
The environmental damage extends beyond factories. Carbon disulfide has contaminated waterways and towns near major production sites. The chemical is still in wide use today, though modern factories vary significantly in how well they control emissions and worker exposure. If environmental impact matters to you, look for viscose certified by programs like the EU Ecolabel or OEKO-TEX, or consider lyocell as an alternative that avoids carbon disulfide entirely.
How to Care for Viscose Clothing
The simplest rule: treat viscose like a delicate fabric, because when wet, it essentially is one. Hand washing in cold water is the safest approach. If you machine wash, use a mesh laundry bag, the gentlest cycle available, and cold water only. Never wring out a viscose garment. Instead, press it gently between towels to remove excess water, then lay it flat or hang it to dry away from direct heat.
Ironing works best on a low setting while the fabric is still slightly damp, or with a pressing cloth between the iron and the garment. Steam can help release wrinkles without direct contact. Viscose wrinkles easily, which is one of its less convenient traits, but proper drying (flat, not bunched in a dryer) reduces the problem considerably.
