Whether a fabric wrinkles more or less depends mainly on the type of fibers it is made from, as well as how the fabric is constructed.
Not all fabrics react the same way to creases, movement and everyday wear.
The different types of textile fibers
Before talking about wrinkle-free fabrics, it’s essential to understand the main families of fibers:
- Natural fibers: derived from plants or animal hair (linen, hemp, cotton, ramie, wool…)
- Man-made (artificial) fibers: derived from processed plant materials (wood, algae, bamboo…)
- Synthetic fibers: derived from petrochemicals
In general, knitted fabrics (such as jersey) wrinkle less than woven fabrics like plain weave or twill.
Similarly, synthetic fibers tend to wrinkle less than fibers of natural origin.
Not all natural fabrics wrinkle in the same way
It’s important to add nuance: not all natural fabrics have the same tendency to wrinkle.
This depends both on the structure of the fiber and its flexibility.
Generally speaking:
- linen is the natural fiber that wrinkles the most
- cotton wrinkles less than linen, but still naturally creases
- viscose (a plant-based man-made fiber) wrinkles even less, thanks to its fluid drape
The more rigid and dry a fiber is, the more visible the creases will be.
Conversely, softer and more fluid fibers tend to wrinkle more gently, creating a more natural appearance.
Why some fabrics wrinkle less than others
Adding synthetic fibers to a natural fabric makes a garment significantly less prone to wrinkles. However, this blend also makes the garment much harder to recycle once the proportion of synthetic fibers exceeds around 5–6%.
Synthetic fibers wrinkle less because they are inert: they do not react to body heat, humidity or movement.
By contrast, natural and plant-based fibers interact with the body and evolve over time.
Linen, for example, changes with washing, wear and body temperature. These materials crease, soften and adapt with movement — they follow our lifestyle and live with us.
In terms of comfort, they are also more breathable than synthetic fibers.
Wrinkle-resistant fabrics: beware of chemical treatments
Fabric composition is not the only factor. The textile industry widely uses chemical finishes, especially to make fabrics wrinkle-resistant.
A natural fabric such as cotton — originally very prone to wrinkling — can undergo chemical treatments to become wrinkle-free.
A natural-fiber shirt that barely wrinkles may seem convenient, but this result is far from natural: it often comes from a cocktail of chemicals that can be harmful to health.
These treatments are still very common, particularly when garments are produced outside Europe, where environmental and health regulations are often less strict. In some regions, such as parts of Asia, the use of more aggressive chemicals remains widespread to meet visual standards (wrinkle-free appearance, perfect hold, easy care).
The same applies to polyester: a polyester garment that does not wrinkle at all has almost always been chemically treated.
This doesn’t mean that every wrinkle-resistant fabric should be avoided — but it is important to understand how and why a fabric behaves the way it does.
How to care for wrinkle-prone garments
A few simple habits can help reduce wrinkles naturally:
- Remove laundry from the washing machine promptly and hang it to dry
- Use steam when ironing to relax the fibers
- After a hot shower, hang shirts on hangers in the bathroom — the steam helps naturally release wrinkles

Looking for fabrics that don’t wrinkle often means prioritizing a perfectly smooth appearance over natural qualities.
Natural fibers wrinkle because they are alive — and that’s exactly what gives them their beauty, comfort and character.
Understanding these differences helps make more informed choices, without guilt, in line with your values, lifestyle and everyday needs.
