What Is Rayon Fabric?
Rayon fabric is made from rayon fibre, a manufactured fibre produced from cellulose, usually taken from wood pulp. Because the cellulose is dissolved and then re-formed into new fibres, rayon is described as a regenerated cellulose fibre. It is not a natural fibre like cotton, which is used as grown, and it is not a synthetic polymer like polyester, which is built from petrochemicals. It sits in between, which explains why it behaves a little like cotton in some ways and quite differently in others.
Brands choose rayon for three reasons: it drapes softly, it feels smooth and cool against the skin, and it takes dye in deep, even colour. Those traits suit dresses, blouses, loungewear and fluid casualwear. The trade-offs are just as important. Rayon is weak when wet, it can shrink and crease, and it needs more care in cutting and sewing than a stable cotton jersey.
The rest of this page is the family overview. Where a topic deserves more depth, we point to the relevant guide, for example modal vs cotton and viscose or the TENCEL and lyocell guide.
Rayon vs Viscose: Is There a Difference?
In everyday buying, rayon vs viscose is mostly a question of vocabulary. Rayon is the generic term, and viscose is the most common process and type of rayon. In the UK and Europe, care labels and fibre composition labels usually say viscose. In the US, the same fabric is more often labelled rayon. If a supplier quotes you rayon and another quotes viscose, they are very likely describing the same family and often the same fibre, but you should confirm which process and which fibre grade is meant.
The distinction matters more when you move beyond standard viscose. Modal and lyocell are also rayon-family fibres, but they are made by modified processes and have different properties, particularly in wet strength and stability. Some are sold under brand names, so a label that says modal or lyocell is not interchangeable with plain viscose in a specification. Our viscose guide covers the standard fibre in depth; this page helps you decide which member of the family fits the product.
Treat rayon as the family name and viscose as the usual type. Always write the exact fibre name you want on the specification, and ask the supplier to confirm it in writing, so that nothing is left to translation between UK and US labels.
The Rayon Family Tree: Viscose, Modal, Lyocell and Others
Several fibres are grouped under the rayon heading. They share a cellulose base but differ in how they are made and how they perform. The table gives a one-line summary of each, written as a general guide rather than a specification.
Rayon-family fibres at a glance
| Fibre | What it is | General character | Where to read more |
|---|---|---|---|
| Viscose (viscose rayon) | The most common regenerated cellulose fibre, made by the viscose process | Soft, fluid drape and good dye uptake; weak when wet; shrinks and creases | Viscose fabric guide |
| Modal | A modified, higher wet-strength type of viscose; Modal is a Lenzing trademark | Very soft and smooth; more stable in washing than standard viscose | Modal vs cotton and viscose |
| Lyocell | A regenerated cellulose fibre made by a solvent spinning process; TENCEL is a Lenzing brand | Strong, smooth and cool; stronger when wet than standard viscose | TENCEL and lyocell guide |
| Cupro | A regenerated cellulose fibre made from cotton by-product material by a different process | Silky, fluid and lining-like; usually a specialist fabric | Ask a specialist mill |
| Bamboo viscose | Viscose made from bamboo pulp; the fibre is still regenerated cellulose | Similar to other viscose in handfeel and care | Bamboo fabric guide |
General descriptions of fibre families. Individual fabrics vary by mill, yarn, construction and finishing. TENCEL and Modal are trademarks of their owner.
For most clothing programmes the realistic choice is between standard viscose, modal and lyocell. Choose based on the wash performance and handfeel you need rather than on the name alone, and sample each option.
How Rayon Fabric Is Made: From Wood Pulp to Garment
Understanding the process explains the fibre. Cellulose is extracted from wood pulp, then chemically treated so that it dissolves into a thick liquid. That liquid is pushed through a spinneret, a plate with many tiny holes, into a bath where it solidifies into filaments. The filaments are washed and finished, then used as continuous filament or cut into short staple fibre and spun into yarn, much like cotton.
From wood pulp to garment
- 1PulpCellulose is taken from wood pulp, ideally from a documented source.
- 2DissolveThe cellulose is treated and dissolved into a spinning solution.
- 3SpinThe solution is extruded through a spinneret into filaments, then washed and finished.
- 4YarnFilament is used directly, or cut to staple and spun into yarn.
- 5FabricThe yarn is woven or knitted, then dyed, finished and relaxed.
- 6GarmentThe fabric is cut, sewn, printed or dyed, washed and tested.
A simplified overview. Exact chemicals, solvents and recovery systems differ by fibre type and producer.
The way the solution is made and recovered is what separates viscose, modal and lyocell, and it is also where most of the sustainability questions arise. We return to that in the sustainability section below.
Properties of Rayon Fabric: Drape, Softness and Weakness
The properties of rayon fabric come from cellulose structure. Like cotton, rayon absorbs moisture readily, which is why it feels breathable and comfortable. Viscose typically has a standard moisture regain of roughly 13 per cent, higher than cotton at roughly 8.5 per cent. That absorbency helps with comfort and dye uptake, but it also means the fibres swell in water and lose strength while wet.
Drape is the main commercial attraction. Rayon yarns are smooth and flexible, so woven rayon hangs and flows in a way that stiffer cotton poplin does not. Softness and a slightly cool, silky handfeel add to that. The weaknesses are the other side of the same coin: low wet strength, a tendency to shrink, easy creasing, and a surface that can distort if the fabric is stretched while damp.

Read the ratings as a profile rather than a verdict. Rayon wins on drape and colour, cotton on all-round stability, and polyester on strength and care. For a wider look at the last pair, see our cotton vs polyester guide.
Rayon vs cotton vs polyester: how to choose
The practical question is not which fibre is best but which one fits the garment. Rayon vs cotton is largely a trade between drape and stability. Rayon vs polyester is a trade between breathability and easy care. The table sets the three side by side on the points a buyer usually needs to settle.
Rayon vs cotton vs polyester for clothing
| Factor | Rayon (viscose) | Cotton | Polyester |
|---|---|---|---|
| Fibre origin | Regenerated cellulose from wood pulp | Natural plant fibre | Synthetic polymer |
| Handfeel | Smooth, soft, cool | Soft but drier and more textured | Ranges from slick to soft depending on finish |
| Drape | Fluid and flowing | Structured, crisper | Varies with filament and weave |
| Washing | Often gentle wash; can shrink and lose strength when wet | Robust; shrinks unless pre-shrunk | Robust; very low shrinkage |
| Creasing | Creases easily | Creases easily | Resists creasing |
| Printing and dyeing | Takes dye deeply; suits reactive and pigment methods | Takes many dyes and inks well | Needs disperse dyes or sublimation |
| Typical garments | Dresses, blouses, loungewear, drapey tees | Tees, hoodies, denim, casualwear | Sportswear, outerwear, uniforms |
General characteristics. Blends, yarn quality, construction and finishing can change any row.
Within cotton there is also a quality ladder, and premium long-staple cottons are covered in our Pima vs Supima cotton guide. Many successful fabrics combine fibres. A rayon-polyester blend keeps some drape while improving crease recovery and stability, and a rayon-cotton blend can add softness to a cotton-led fabric. If you are still at an earlier stage, our overview of types of fabric for clothing shows where each fibre family fits.
Woven and Knit Rayon Fabrics, Weights and Blends
Rayon fabric is sold in many forms, and the construction changes the behaviour as much as the fibre does. Woven rayon includes challis, a soft, lightweight plain weave with a brushed feel, as well as crepe, twill and poplin-type weaves. Knitted rayon includes single jersey and rib, usually with elastane added for recovery. Each suits a different type of garment.
Common rayon constructions and typical uses
| Fabric | Structure | Typical use |
|---|---|---|
| Rayon challis | Woven, plain weave, lightweight with a soft handle | Dresses, blouses, skirts, scarves |
| Rayon crepe | Woven, twisted yarns give a pebbled surface and fluid drape | Dresses, tops, trousers |
| Rayon twill | Woven, diagonal weave, a little more body | Shirts, trousers, light jackets |
| Rayon poplin | Woven, tight plain weave, smoother and crisper | Shirts and shirt-dresses |
| Rayon jersey | Knit, single jersey with a soft, drapey handle | T-shirts, loungewear, dresses |
| Rayon rib | Knit, vertical ribs with good stretch | Fitted tops, cuffs, bodycon styles |
General descriptions. Names and exact structures vary between mills; always confirm against a swatch.
Weight is the next specification after construction. The chart shows broad typical weight bands in grams per square metre. Real fabrics can fall outside these ranges, so use them to sense-check a quote, not to set one. Our fabric GSM guide explains how to read and specify weight.
Typical weight bands for rayon fabrics
Grams per square metre (GSM)
Typical ranges only; they vary by product, yarn, mill and finish. Not a specification.
Blends are common. Rayon-spandex jersey adds stretch and recovery for fitted garments (see our spandex and elastane fabric guide for how stretch is specified), while rayon-polyester blends improve crease recovery and reduce shrinkage risk. Rayon-cotton blends are used to add a softer, more fluid feel to cotton-led fabrics. In any blend the minority fibre still changes the behaviour, so test the actual blend rather than assuming it falls halfway between the two.
What Is Rayon Fabric Used For in Clothing?
Rayon fabric suits garments where fluid drape and a soft, cool feel are the point of the product. Woven rayon is a familiar choice for summer dresses, blouses, relaxed shirts, wide-leg trousers and wrap styles. Rayon jersey is common in loungewear, nightwear, drapey t-shirts and bodycon tops, often with a little elastane.
Garments and rayon options
| Garment | Usual rayon option | What to watch |
|---|---|---|
| Dresses and skirts | Challis or crepe, medium to light weight | Seam slippage, shrinkage, lining or opacity needs |
| Shirts and blouses | Challis, twill or poplin-type weave | Creasing, collar and placket stability, interlining |
| Loungewear | Rayon jersey or rayon-spandex jersey | Growth, pilling and shrinkage after washing |
| T-shirts | Rayon or rayon-blend jersey | Curling at edges, neckline stability, shrinkage |
| Trousers and shorts | Twill or crepe with some body | Knee and seat bagging, creasing |
General guidance for typical constructions. Confirm every choice with samples and testing.
A note on fit with our own range: most of the above sits partly outside the core categories Ruhrose develops, which are cotton and cotton-blend jersey, fleece, French terry, denim and woven cotton casualwear. Rayon blends in jersey or casual wovens can be discussed with the factory case by case, but availability is never assumed. For comparison, our jersey fabric guide shows how the knit constructions work in our core cotton range.
Cutting, Sewing and Printing Rayon
Rayon is slippery and moves under the cutter and the needle, so factories treat it differently from cotton. The most important step happens before cutting: let the fabric relax. Rolled fabric holds tension from weaving, knitting and finishing, and if it is cut straight from the roll it can shrink or distort after washing. Relaxing the fabric, laying it without stretch and allowing it to rest reduces that risk.
Sewing rayon without puckering
Use a fine, sharp needle so that it pierces rather than pushes the yarns. Light-weight rayon is prone to seam puckering and slippage, so factories typically adjust stitch length, thread tension and presser foot pressure, and may use stay tape or interlining at stress points. Test seam strength and appearance on a sample before the whole run is cut.
Printing and dyeing rayon
Rayon takes dye deeply, which is why saturated, rich colours are one of its strengths. As a cellulose fibre it is dyed in much the same family of dye classes as cotton, although shades and fastness need checking fabric by fabric. Printed rayon can look very sharp, but wet processing can cause shrinkage, so confirm print placement after finishing. For decoration choices see our guide to DTG printing, and ask the printer about rayon blends before committing.
Rayon fabric: strengths and limits
Strengths
- Soft, fluid drape that flatters
- Cool, smooth handfeel
- Deep, rich colour from dye and print
- Breathable and comfortable in warm weather
Limits
- Low wet strength
- Can shrink noticeably if not relaxed and tested
- Creases easily
- Needs more careful cutting and sewing
General characteristics of standard viscose rayon. Modal and lyocell perform differently on wet strength.
How to Wash Rayon and Control Shrinkage
Learning how to wash rayon correctly protects the garment, and this is the question most customers ask after buying. Because the fibres are weakest when wet, a rayon garment should be handled gently. Follow the care label first. Many rayon garments call for a cool, gentle machine wash or hand wash, with a low spin and no wringing or twisting. Dry flat or hang to dry, avoid hot tumble drying, and iron on a low setting if needed.
Specify the care label from the test results, not from habit. Wash cool and gentle, avoid wringing, dry flat or hang, and use a cool iron. If the garment will be dry-clean only, say so clearly on the label so that customers are not caught out.
Shrinkage deserves its own specification. Rayon fabric can shrink more than treated cotton, and the amount depends on construction, finishing and whether the fabric was relaxed. Factories and test houses use home-laundering test families such as AATCC 135 and ISO 6330, often together with a dimensional change method such as ISO 5077, to measure how much a fabric changes. Ask which method will be used and what tolerance is acceptable. Our garment testing guide explains the main tests, including colour fastness and pilling.
Is Rayon Sustainable?
Rayon fabric is not automatically eco-friendly, and it is not automatically harmful either. The fibre starts as a plant material, which is a point in its favour, but turning wood pulp into fibre involves chemical processing, energy and water. The impact depends heavily on where the wood comes from and how the producer manages chemicals, emissions and waste.
Two questions matter most. First, wood sourcing: ask whether the pulp comes from certified or documented forests, and look for schemes such as FSC or PEFC. Second, process management: ask whether the mill uses recognised chemical management and recovery systems and holds independent certifications. OEKO-TEX Standard 100 addresses harmful substances in finished textiles, and some fibres are sold with their own producer certifications. Avoid broad claims in your marketing that you cannot back up with documents.
Fibre choice also affects the end-of-life picture. Cellulose fibres can break down in suitable conditions, but blends with elastane or polyester are harder to recycle. Our guide to sustainable fabrics for clothing brands goes further on certification and on how to word claims carefully.
How to Specify Rayon Fabric With a Mill or Factory
A clear specification avoids most rayon problems. Name the exact fibre or fibres, the percentages in any blend, the construction, the weight and the finish. Ask for a handloom or swatch, then request a lab test on the swatch before you approve bulk fabric. The checklist below covers what to include and what to ask for.
What to ask for on a rayon swatch and sample
- Exact fibre name (viscose, modal, lyocell) and blend percentages
- Fabric construction (challis, crepe, twill, jersey) and weight in GSM
- Fibre source and any wood-sourcing certificates such as FSC or PEFC
- Relevant certifications, for example OEKO-TEX Standard 100, if you want to claim them
- Shrinkage results after a home-laundering test, in warp and weft or wales and courses
- Colour fastness to washing, rubbing and perspiration for dyed or printed shades
- Pilling and seam slippage results for the actual fabric
- Care instructions based on the wash test, not copied from another garment
Agree test methods and tolerances in writing before bulk fabric is ordered.
Ask the factory to make the pre-production sample from the actual bulk fabric, not a similar one. Wash it, measure it, and compare it with the grade you approved. Rayon is forgiving of mistakes in a flat sample and unforgiving in bulk if the fabric differs.
How Ruhrose Approaches Rayon Fabric
Ruhrose develops hoodies, jersey, denim and woven casualwear for UK buyers, with development and production in Bangladesh. Our core fabrics are cotton and cotton-blend jersey, fleece, French terry, denim and woven cotton casualwear. Rayon blends in jersey or casual wovens can be discussed with the factory case by case, and we do not promise availability before a swatch and sample have been checked. For specialist rayon dresses or shirting, a mill or factory that focuses on fluid wovens may suit you better. If you are comparing fabric options for a range, our types of fabric guide is a good place to start.
