Drying, ironing, storage
a full parameter checklist: tumble dryer, iron, hanger or folding
Lyocell has lower wet strength than cotton, so wet fabric easily stretches under its own weight if you don't take proper care when drying. This is why wringing by twisting is one of the worst possible moves with this fabric: it stretches the fiber while swollen exactly at the fold line and locks in a deformation that no amount of ironing can undo.
The good news is that lyocell forgives almost everything except a handful of specific mistakes. You just need to know the right order of steps for drying and ironing, and recognize the moment when the fabric itself signals that it's better to hand it to a laundry than risk another attempt at home.
Why lyocell behaves differently than cotton
regenerated cellulose, wet strength and fibrillation risk
Lyocell is a regenerated cellulose fiber, made from dissolved wood pulp, not a natural fiber that grows straight into a finished structure the way cotton does. That difference in structure means the fiber swells more under water, and its strength drops more noticeably than cotton's.
While swollen, the microscopic fibrils on the fiber's surface separate more easily under mechanical friction. A high-temperature tumble dryer combines exactly those two factors, moisture and friction, which is why it intensifies fibrillation and surface dulling more than any other drying method. A hot iron carries a different risk: stiffening the fabric and losing its characteristic sheen.
Drying and ironing parameters at a glance
Below 60 degrees Celsius, if using a tumble dryer at all. Safer to dry naturally, on a flat surface or on a hanger
About 110-150 degrees Celsius, silk or wool setting
Slight fabric moisture makes pressing out stubborn wrinkles easier
Avoid direct sun while drying, especially for dyed fabric
Drying and ironing step by step
from pressing out water to the final pass with the iron
- 1
Press out water gently
Never twist wet fabric. Press out excess water with your hands, or wrap the item in a terry towel and press gently so the towel absorbs the moisture.
- 2
Choose low-temperature drying
A high-temperature tumble dryer combines moisture with friction, so it intensifies fibrillation the most. Safer options are drying below 60 degrees Celsius or natural drying.
- 3
Lay flat or hang depending on the cut
Dry structured items, such as shirts or dresses, on a hanger. Lay knitwear flat, because a hanging wet knit stretches under its own weight.
- 4
Dry away from sun and radiators
Direct sunlight fades dyed lyocell unevenly, and a radiator dries the fiber out too quickly and encourages stiffening.
- 5
Set the iron to silk or wool
A temperature of about 110-150 degrees Celsius is enough to press out even stubborn wrinkles without risking scorching.
- 6
Iron through a cloth and lightly dampen stubborn spots
Direct contact between the soleplate and a print or applique at the upper end of the range risks scorching. A little water on wrinkles that won't settle makes them easier to press out, because cellulose responds well to the combination of moisture and heat.
Now that you know how to dry and iron, a quick reference for care symbols on the label will be helpful so you don't have to look up these rules every time. Symbols on the label cover the whole care cycle, not just drying and ironing, so it's worth knowing the ones for washing and bleaching too.
Care symbols relevant for lyocell
Washing
Wash at 30 degrees Celsius
A basin of water with the number 30 means gentle washing at low temperature, the standard recommendation for most lyocell.
Wash at 40 degrees Celsius
Higher threshold allowed for reinforced fabrics, such as bedding, but still with a gentle program.
Bleaching
Ban on chlorine bleach
A crossed-out triangle means no chlorine. It oxidizes cellulose and permanently weakens the fiber structure.
Tumble dryer
Low-temperature drying or ban
A square with a dot or crossed-out square with a circle: high-temperature tumble dryers intensify fibrillation and shrinkage.
Ironing
Ironing up to about 150 degrees Celsius
One or two dots on the iron: low to medium temperature, consistent with silk or wool settings.
Dry cleaning
Dry cleaning (P)
A circle with the letter P applies to some lyocells with water-unstable finishes or glued elements.
Common mistakes when drying and ironing
what to avoid so you don't have to rescue the fabric afterward
Drying and ironing lyocell in a nutshell
Do
- Press out water with your hands or a terry towel
- Dry at low temperature or naturally, flat or on a hanger
- Iron through a cotton cloth or from the reverse side
- Lightly dampen the fabric before pressing out stubborn wrinkles
Don't
- Don't wring wet fabric by twisting it
- Don't tumble dry at high temperature
- Don't leave wet lyocell to dry in direct sunlight
- Don't exceed an iron temperature of about 150 degrees Celsius
Storage: hanger or folding
different rules for structured fabric than for knitwear
When storing structured clothing, such as shirts or dresses, a hanger works better: the fabric keeps the shape of the shoulders and doesn't crease in places you'd have to iron before wearing it anyway. Lyocell knitwear is safer to fold, to avoid permanent stretching under its own weight, especially during longer seasonal storage.
This rule applies only to dry fabric. Never hang wet or even slightly damp lyocell knitwear to dry, because lower wet strength means it stretches fastest right then. Dry it flat until it's completely dry first, and only afterward decide whether the item goes on a hanger or into a drawer.
When to hand lyocell to a laundry
If the fabric has turned dull and rough to the touch after drying, you notice small pills on the surface, or wrinkles won't budge even after steam ironing, home methods have run their course. These are usually signs of fibrillation or overly intense mechanical handling, and another wash in the same dryer won't undo them. In that situation, it's better to hand the item to a professional laundry that will match temperature and technique to the fiber's current condition instead of risking further damage.
Now you know the theory. Practice can be less forgiving.

Frequently asked questions
It's best to avoid high-temperature tumble drying, because it combines moisture with mechanical friction and intensifies fiber surface fibrillation the most. Low-temperature drying below 60 degrees Celsius or natural drying, flat or on a hanger depending on the cut, is safer.
Yes, on silk or wool setting, about 110-150 degrees Celsius, preferably through a cotton cloth or from the back of the fabric. Slight fabric moisture facilitates pressing out wrinkles, because cellulose responds well to the combination of moisture and heat. Avoid direct contact between the soleplate and prints or appliques at the upper end of the range, as it risks scorching. Temperatures above 150 degrees Celsius also risk stiffening the fabric and losing its characteristic sheen.
Yes, steam helps press out wrinkles because cellulose responds well to the combination of moisture and heat. Keep the iron on the silk or wool setting and preferably iron through a cotton cloth, to avoid a burst of hot steam hitting the delicate fiber too directly.
It's usually the effect of fibrillation: while swollen with water, microscopic fibrils on the fiber's surface separate under mechanical friction inside the drum. The surface then loses its sheen and turns rough to the touch. Low-temperature or natural drying limits this risk, because it limits both temperature and friction intensity.
Hang structured items like shirts and dresses on a hanger, but fold lyocell knits, because they stretch permanently under their own weight. Lyocell has lower wet strength than cotton, so never hang a wet knit to dry. Dry it flat and don't wring it by twisting.
