Rayon Meaning on a Care Label
Short answer: The rayon meaning is simple: rayon is another word for viscose, a fibre made from plant material that is processed into thread. On a label it often appears as rayon, viscose or the short code VI. Here is what the word means and how to look after the clothes.
What rayon actually is
Rayon is a fibre made from plant cellulose that is dissolved and spun into thread. Because the raw material is natural but the thread is made in a process, it is often called a man made fibre. Many people know it as artificial silk, since it can have a soft, smooth drape.
Rayon, viscose and artificial silk
The three words are often used for the same thing, but not always in exactly the same way. Viscose is the most common type of rayon, and artificial silk is an older word for these fibres. If a label from abroad says rayon, it is usually the same family as viscose here. That is the practical rayon meaning on most labels.
Where bamboo fits in
Bamboo in clothing is viscose made from bamboo, so it belongs to the same family. The plant is the raw material, but the thread is made through a process. If you browse the full bamboo range for men, the label will often mention viscose, and then you know what you are looking at.
How to read a label
On a label the fibres are listed with percentages, and the largest share shapes the fabric most. Read the whole list, because a blend can behave differently from a single fibre. Look at the care symbols too, which show how the fabric should be washed.
How rayon feels
Many people find rayon soft, smooth and easy to wear. The fabric drapes well and often feels cooler than thick fabrics. At the same time it can wear and crease, so it deserves a little thought in the wash, especially if you wear the garment often.
Washing and drying
Rayon and viscose can be delicate when wet, so wash gently and follow the instructions. Avoid high heat in the dryer, which can shrink clothes. Let them dry flat or on a hanger and shake them out so creases do not set.
Watch out for blends
Many garments are a blend of rayon and other fibres such as cotton or elastane. Then you follow the instructions for the blend, not just for rayon. Elastane adds stretch and cotton adds structure, so washing and drying can differ a little from pure viscose.
What the word does not tell you
The word says something about the type of fibre, but not about quality, knit or sewing. Two sweaters made of rayon can feel very different. For everyday wear, you can for example look at bamboo clothing for men and bamboo T-shirts for men and read the description of each item.
Frequently asked questions
Are rayon and viscose the same?
Almost. Viscose is the most common type of rayon, so many labels use the two words for the same family of fibres. Always follow the instructions for the specific garment.
Is rayon a natural fabric?
The raw material comes from plants, but the fibres are made in a process. That is why rayon is often called a processed fibre rather than a fully natural fibre like cotton.
Can rayon go in the tumble dryer?
It depends on the label. Many garments handle it poorly because heat can shrink the fabric, so read the care symbols and choose flat drying if in doubt.
