What is Rayon?

Rayon is a manufactured fibre made from cellulose, a natural material found in plants. The cellulose, most commonly sourced from wood pulp, is chemically processed, dissolved and regenerated into fibres that can be spun into yarn and made into fabric. Because it begins with a natural plant based material but requires substantial processing to become a textile fibre, rayon is commonly described as a regenerated or semi-synthetic cellulose fibre.

Rayon fabrics are generally known for being soft, smooth and highly absorbent, with excellent drape. Depending on the type and construction, rayon can be used to create fabrics with characteristics similar to cotton, linen or silk.

Is rayon natural or synthetic?

Rayon sits in an interesting middle ground.

Its raw material is cellulose, which occurs naturally in plants. However, cellulose doesn't come off a tree looking remotely like a shirt. It has to undergo considerable chemical processing before it can be transformed into a usable textile fibre.

For this reason, rayon is usually classified as a regenerated cellulose fibre or sometimes a semi-synthetic fibre.

It isn't considered a natural fibre in the same way as cotton, wool or linen, but it also isn't a fully synthetic petroleum derived fibre like conventional polyester or acrylic.

What is rayon made from?

Rayon is made from cellulose, usually obtained from wood pulp.

The basic process involves extracting cellulose, chemically treating and dissolving it, and then forcing the resulting solution through extremely small openings called spinnerets.

The cellulose is regenerated into fine filaments, which can then be processed into yarn.

That yarn is subsequently knitted or woven into fabric.

There are several different processes for producing regenerated cellulose fibres, which is why rayon isn't really one single, identical material.

Is rayon the same as viscose?

Viscose is a type of rayon.

The terminology can be confusing because rayon and viscose are sometimes used almost interchangeably in everyday clothing descriptions.

Technically, rayon is the broader family of regenerated cellulose fibres, while viscose describes rayon produced using the viscose manufacturing process.

In Australia, you're particularly likely to encounter the word viscose on garment fibre-content labels, while "rayon" is commonly used as the broader textile term in other markets.

So if a garment says 100% viscose, you're looking at a regenerated cellulose fibre belonging to the rayon family.

Are there different types of rayon?

Yes, this is where things get interesting.

Viscose

Viscose rayon is probably the most familiar form. It is known for softness, absorbency and fluid drape and is widely used in clothing.

Modal

Modal is another regenerated cellulose fibre, commonly made from beechwood cellulose. It is particularly associated with soft, smooth fabrics and is often found in underwear, T-shirts, active basics and garments designed for next-to-skin comfort.

Lyocell

Lyocell is also a regenerated cellulose fibre, but it is produced using a different manufacturing process from conventional viscose.

TENCEL™ is a well-known branded range of lyocell and modal fibres rather than another generic name for rayon.

There are important differences between the manufacturing processes and performance characteristics of these fibres, so it isn't quite accurate to treat every regenerated cellulose textile as identical.

What does rayon feel like?

Rayon is generally known for feeling soft, smooth and comfortable against the skin.

One of its most distinctive characteristics is its drape.

Rather than producing a particularly stiff or structured fabric, rayon yarns can be used to make fabrics that fall and move fluidly, making them popular for dresses, blouses, skirts and flowing garments.

However, the finished feel depends on the particular rayon fibre, yarn, fabric construction, weight and finishing process.

Just like polyester, saying something is "rayon" doesn't tell you exactly what the finished fabric will feel like.

Is rayon breathable?

Rayon is generally highly absorbent, which can contribute to comfortable clothing in warmer conditions.

It readily absorbs moisture, unlike fibres such as conventional polyester, which have relatively low moisture absorbency.

However, breathability is influenced by much more than fibre content. The weight, density and construction of the fabric also determine how easily heat and moisture can move through a garment.

A lightweight rayon fabric can therefore feel beautifully cool and fluid, while a heavier or more densely constructed rayon fabric will behave differently.

Does rayon stretch?

The rayon fibre itself isn't normally considered highly elastic.

However, the finished fabric may have some give depending on its construction.

A rayon jersey, for example, can have substantial mechanical stretch because jersey is a knitted construction, which gives us a perfect internal link to What is Jersey?

Rayon is also frequently blended with elastane when manufacturers want additional stretch and recovery.

This is a good example of why fibre and fabric construction need to be considered separately.

Does rayon wrinkle?

Rayon can be prone to creasing, particularly in lightweight woven fabrics.

Again, the extent depends on the specific fibre, fabric construction and any finishing treatments.

Blending rayon with other fibres can also change its crease resistance and overall performance.

Is rayon durable?

Rayon's durability varies considerably depending on the type of rayon and how the fabric has been manufactured.

Traditional viscose can lose strength when wet, meaning garments may require more careful washing and handling than robust polyester or cotton/polyester uniform fabrics.

Newer regenerated cellulose fibres and different fabric constructions can perform differently.

The care label is therefore particularly important with rayon garments.

Does rayon shrink?

Rayon can shrink or change shape if it isn't cared for correctly.

Heat, agitation and moisture can affect some rayon fabrics, and certain garments may require gentle washing, hand washing or dry cleaning.

You shouldn't assume that because one viscose garment is machine washable, another one will be too.

Always follow the manufacturer's care instructions.

Is rayon biodegradable?

Rayon is made primarily from cellulose and unmodified regenerated cellulose fibres can biodegrade under appropriate environmental conditions.

The environmental story is considerably more complicated.

A finished garment can contain dyes, chemical finishes, blended fibres, elastane, sewing threads and other components, all of which can affect how it behaves at the end of its life.

Manufacturing method and the sourcing of the original cellulose also matter when assessing environmental impact.

So "plant-derived" shouldn't automatically be interpreted as "environmentally friendly."

Is rayon sustainable?

There isn't a universal yes-or-no answer.

Rayon's plant-based cellulose can come from renewable sources, but producing traditional viscose requires chemical processing. Environmental performance therefore depends heavily on factors such as :

where the cellulose came from, how forests were managed, the manufacturing process, chemical recovery systems and wastewater management.

More modern closed-loop manufacturing processes can recover and reuse a high proportion of processing chemicals, which is one reason fibres such as lyocell have become prominent in discussions around lower-impact textiles.

As always, vague green claims are considerably less useful than knowing what the fibre actually is, where it came from and how it was produced.

Rayon vs polyester

Rayon and polyester can both be manufactured into soft, lightweight fabrics, but they're fundamentally different fibres.

Rayon begins with plant-derived cellulose and is regenerated through chemical processing. It is generally absorbent and can produce very soft fabrics with excellent drape.

Polyester is a synthetic polymer fibre. It generally absorbs little moisture, dries quickly and offers excellent durability and easy-care performance.

Rayon vs cotton

Both rayon and cotton are cellulose-based, but they're produced very differently.

Cotton is a natural fibre harvested from the cotton plant.

Rayon takes naturally occurring cellulose, commonly from wood and chemically processes it to regenerate an entirely new textile fibre.

Both can produce soft and absorbent fabrics, but their performance and care requirements can differ considerably.

What clothing is made from rayon?

Rayon and viscose appear across a huge range of clothing, including:

• blouses and tops
• dresses
• skirts
• shirts
• T-shirts
• trousers
• lightweight knitwear
• underwear
• sleepwear
• fashion garments
• corporate clothing

You'll also frequently find rayon or viscose blended with other fibres to alter the feel, drape, stretch or performance of the finished fabric.

Rayon and viscose in uniforms

Viscose is particularly relevant to corporate and fashion led uniform garments where softness, drape and appearance are important.

You'll find it in some women's corporate tops, blouses, knitwear, dresses and stretch garments, often blended with fibres such as polyester, nylon or elastane.

Compared with a traditional polyester/cotton work shirt, a viscose-blend garment may offer a much softer and more fluid feel.

That doesn't automatically make it better or worse, it simply means the garment has been designed around different priorities.

For uniforms that will be washed extremely frequently or exposed to demanding conditions, care requirements and durability should always be considered alongside comfort and appearance.
