What Is Viscose Fabric?
Viscose fabric is made from viscose fibre, a manufactured fibre produced from cellulose, usually taken from wood pulp. Because the cellulose is dissolved and then re-formed into a fibre, viscose belongs to the group called regenerated cellulose fibres. In the United States and in some other markets the same fibre is sold under the name rayon. In the UK and EU, viscose is the standard fibre name and the one that appears on care labels.
Viscose is neither a fully natural fibre nor a fully synthetic one. The raw material is a plant, but the fibre is created in a chemical process, which is why textile professionals call it man-made or semi-synthetic. Its chemistry is close to cotton, so it takes dye in a similar way and absorbs moisture readily, but its fibre length, shape and surface are very different, which gives it a smooth, fluid character.
Viscose has several close relatives, including modal, TENCEL lyocell and the so-called bamboo fabrics. We compare them later in this guide.
How Viscose Fabric Is Made
The manufacturing route explains both the appeal and the sourcing questions. At a high level, wood pulp is treated and dissolved in chemicals to form a thick syrup. That solution is pushed through fine nozzles into a bath where the cellulose solidifies again as continuous filaments. The filaments are washed, finished and then used as filament yarn or cut into short staple fibre that can be spun like cotton.
From tree to viscose yarn
- 1Wood pulpCellulose is separated from wood and prepared as dissolving pulp.
- 2DissolvingThe pulp is treated with chemicals until it forms a viscous solution.
- 3SpinningThe solution is extruded through spinnerets into a bath that sets the filaments.
- 4Washing and finishingResidual chemicals are washed out and the fibre is finished.
- 5Yarn and fabricFibres are spun or used as filament, then woven or knitted into fabric.
Simplified overview. The details differ by producer and by fibre type.
Some of the chemicals used in conventional viscose production are hazardous if they are not handled in controlled, well-managed systems. That is the main reason buyers are encouraged to ask about the mill and the fibre producer, rather than assuming that all viscose is the same.
Viscose Fabric Properties
Viscose fabric is valued first for how it moves. The fibres are smooth and fine, so woven viscose hangs and flows and knitted viscose feels cool and fluid. The table below summarises the properties that matter most when you are choosing it for a garment.
Viscose fabric properties at a glance
| Property | Typical behaviour | What it means for a garment |
|---|---|---|
| Drape | Fluid, soft and heavy for its weight | Dresses, blouses, wide-leg trousers and skirts that hang well |
| Handfeel | Smooth, cool and soft | Comfortable next to skin; premium look for the price |
| Absorbency | Absorbs moisture readily | Comfortable in warm weather; slow to dry |
| Wet strength | Weakens noticeably when wet | Needs gentle washing; fabric can stretch or distort when wet |
| Shrinkage | Can shrink and relax significantly if not controlled | Needs pre-treatment, tested shrinkage and a generous allowance in patterns |
| Wrinkling | Creases easily | Often needs ironing; blends or finishes can help |
| Colour | Takes vivid, deep dyes | Rich colour and strong print definition |
| Durability | Moderate, lower when wet | Not ideal for harsh abrasion or heavy repeated washing |
General characteristics; yarn type, fabric construction and finishing will shift any row.
Typical weights vary a great deal with construction. Light woven challis suits shirts and dresses, while heavier twills and crepes suit trousers and structured pieces. The chart below shows broad bands to guide a conversation with a mill.

Viscose vs Cotton vs Polyester
Viscose is often chosen as a more fluid alternative to cotton, or a more breathable one to polyester. Direct comparison is useful, but remember that each fibre has a job. Our wider guide to cotton vs polyester covers those two in more depth.

Indicative ratings based on typical fabric/process characteristics, not laboratory results.
The pattern is clear: viscose wins on drape and feel, and loses on strength when wet, shrink stability and ease of care. That is why viscose is often blended, for instance with polyester for structure or with elastane for recovery.
Where Viscose Fabric Is Used and How It Is Blended
Viscose fabric turns up across womenswear, menswear and loungewear, mostly where drape and a soft, cool feel are the selling points. Typical uses include dresses, blouses, relaxed shirts, wide-leg trousers, skirts, scarves, soft jersey tops and linings. In plain tees and hoodies it is less common, because cotton is stronger and easier to care for.
Blending is the most practical way to manage the weaknesses of viscose. Each partner fibre solves a different problem:
- Viscose with elastane adds stretch and recovery in jersey, so tops and dresses keep their shape.
- Viscose with polyester adds wet strength, crease resistance and easier care, at some cost to breathability.
- Viscose with cotton in jersey gives a softer, more fluid feel than cotton alone, with better stability than pure viscose.
- Viscose with linen or other fibres in woven fabrics creates textured, relaxed casualwear cloths.
Whenever you choose a blend, check the proportion on the specification and the label. The fibre that dominates sets the character of the fabric, and the fibre content declared on the care label must match what is actually in the cloth.
Woven vs Knit Viscose Fabric
Viscose appears in both woven and knitted fabrics, and the construction decides how it behaves in cutting and sewing. Woven viscose, such as challis, twill or crepe, is stable across the grain but frays easily and can slip when cut. Knitted viscose jersey is very soft and stretchy but can twist, curl and grow in length when hung.
Woven and knitted viscose fabric
| Aspect | Woven viscose | Viscose jersey |
|---|---|---|
| Common products | Dresses, shirts, skirts, trousers, linings | Tops, tees, loungewear, dresses |
| Cutting | Slippery; needs careful lay-up and sharp cutting | Edges curl and the fabric can grow when hung |
| Sewing | Fine needles and appropriate seam finishes limit fraying and puckering | Ballpoint needles and stretch stitches; stabilise necklines and shoulders |
| Main risk | Seam slippage and fraying | Distortion, growth and twisting after washing |
| Typical fit in a range | Woven casualwear: a legitimate area to discuss | Cotton-viscose and viscose-elastane jersey blends can be discussed |
Ruhrose works in jersey and woven casualwear; pure and blended viscose options should be confirmed at sampling.
For knitted viscose it also helps to understand how base jersey is built and specified. Our jersey buying guide covers the questions to ask any supplier.
Shrinkage, Wet Strength and Why Viscose Fabric Needs Testing
Two behaviours account for most disappointment with viscose fabric. First, it weakens when wet, so a heavily wrung or hot-washed garment can lose shape or even tear at stress points. Second, it can shrink or relax considerably, especially in the first wash, and woven constructions often shrink more in one direction than the other.
Neither problem is a reason to avoid viscose. They are reasons to specify and test carefully. Ask the mill about pre-shrinking or relaxation treatments, set a target shrinkage tolerance, and test the actual bulk fabric. Our guide to garment testing lists the shrinkage and colour fastness tests to request, and a well-run sampling process should include a wash test on the sample, not just a visual check.
Because viscose relaxes after washing, a pattern drafted without considering shrinkage can produce a garment that is shorter or narrower than the size chart. Share the tested shrinkage results with your pattern maker, and re-check measurements after a wash.
Viscose Fabric Care
Care instructions for viscose fabric depend on the construction and any finishing, so the label should come from testing rather than assumption. As a general guide, cool or gentle washing, light spinning and drying flat or on a line reduce the risk of distortion. Some viscose garments are labelled dry clean only because the fabric or the construction cannot be relied on to survive washing.
- Wash cool or on a gentle cycle, and avoid heavy wringing.
- Use a low iron temperature while the fabric is slightly damp, or steam.
- Avoid tumble drying unless the care label says it is suitable.
- For dark or printed fabrics, test colour fastness before choosing home washing.
The care label is a promise to your customer. If testing shows the garment only survives hand or dry-clean care, say so clearly rather than choosing the easiest label.
Sustainability: Questions to Ask About Viscose
Viscose is often described as a natural or sustainable fibre because it starts as wood. That description oversimplifies. Wood pulp can come from well-managed or poorly managed forests, and conventional production uses chemicals that need careful handling, so impact depends heavily on where and how the fibre is made.
Questions to ask about sourcing viscose
| Topic | What to ask | Evidence to request |
|---|---|---|
| Forest sourcing | Where does the wood pulp come from, and is it from certified forests? | Forest certification such as FSC or PEFC chain-of-custody documents |
| Fibre producer | Who makes the fibre, and how is chemical handling managed? | Producer or mill documentation, audit summaries |
| Branded fibres | Is the fibre a branded lower-impact viscose, for example LENZING ECOVERO, and can the supplier prove it? | Brand licence or traceability documents from the fibre owner |
| Mill and dyeing | How is dyehouse wastewater treated? | Relevant certifications such as OEKO-TEX Standard 100 for product safety |
| Claims | What will the label and website say? | Evidence for every claim you intend to make |
Branded fibres can be one route to a lower-impact viscose but should be verified, not assumed. See our guide to sustainable fabrics for how to treat claims.
Be cautious with broad terms such as eco-friendly. A more specific and verifiable statement, for example naming a certification you hold, protects your brand better.
How to Specify Viscose Fabric for Production
A clear specification stops mills and factories from quoting different fabrics under the same name. Treat the fibre as only one line of a longer specification.
Viscose fabric specification checklist
- Fibre content and any blend, for example viscose with elastane or polyester
- Construction: woven type, or knit structure and gauge
- Weight in GSM, with a tolerance
- Finish: pre-shrunk, softened, easy-care, or none
- Shrinkage target after washing in both directions
- Colour fastness requirements and dye method
- Certifications to request: for example FSC or PEFC pulp, OEKO-TEX Standard 100
- Swatch and lab-dip approval before bulk
Weights should always be written as GSM, grams per square metre, so quotes can be compared like for like.
When asking for a swatch, request the actual bulk fabric if possible, and wash it yourself. A handful of wash cycles will reveal more than any description.
How Ruhrose Approaches Viscose Fabric
Ruhrose develops hoodies, jersey, denim and woven casualwear for UK buyers, with production in Bangladesh. Viscose and viscose-blend fabrics can come up in drapey woven casualwear and soft jersey, and we treat them as a sampling question: we discuss the composition, weight and care route, test shrinkage and colour fastness, and tell you early if a fabric is not a good fit. Specialist viscose products such as technical or premium evening wear sit outside our core range.
