When choosing quality women’s pyjamas, the fabric matters more than the cut: the fibre determines how breathable the garment is, how it absorbs moisture, how it drapes and how it looks after many washes. Cotton, modal and viscose can look almost identical in photos, but their properties differ considerably once worn and cared for. This article will help you use the fabric composition to choose the set that suits you best when shopping online: you will find a comparison of the six most popular fabrics, the real differences between modal and viscose, and practical tips.
Key takeaways
- The fabric name in a product description does not tell the whole story: what matters most is how breathable the material is, how much moisture it holds, how it drapes and how it looks after washing.
- Materials that look alike (for example, modal and viscose, or satins made from different fibres) reveal entirely different properties when worn and cared for, so appearance in a photo should not be the main deciding factor.
- The most accurate source of product information is the garment label, as other claims in the description are often only general.
Pyjama fabric guide: cotton, modal and viscose compared
| Fabric | Fibre type | Feel and drape | Breathability and moisture | Care |
|---|---|---|---|---|
| Cotton | Natural plant fibre | Soft, matte surface, holds the garment’s shape well | Highly breathable, absorbs moisture well, but dries slowly | Wash at 30-40 °C, withstands frequent washing, creases easily |
| Cotton and modal | Blend of natural and regenerated cellulose fibres | Smoother and softer surface than pure cotton | As breathable as cotton, but dries faster | Wash at 30 °C, creases less |
| Modal | Regenerated cellulose fibre (an improved form of viscose) | Smooth and silky soft, with a light, elegant drape | Breathable, absorbs moisture well and dries quickly | Wash at 30 °C, stays stronger than viscose when wet |
| Viscose | Regenerated cellulose fibre | Light, thin fabric that drapes beautifully against the body | Breathable, absorbs more moisture than cotton | Wash at 30 °C on a gentle cycle, loses strength when wet, do not wring hard |
| Viscose satin | Regenerated cellulose fibre, satin weave | Subtly lustrous, exceptionally smooth, with a loose drape | Breathable, absorbs moisture well | Wash at 30 °C, ironing through a pressing cloth is recommended |
| Polyester satin | Synthetic fibre, satin weave | Vivid silky sheen, rich texture, keeps prints and colours for a long time | Absorbs almost no moisture, retains body heat | Machine washable, dries very quickly, hardly creases |
What fabrics are used for pyjamas?
Women’s pyjamas are most often made from cotton, modal, viscose, polyester or various blends of these fibres. Cotton is a natural plant fibre. Modal and viscose are made by processing wood cellulose, which gives them a natural character and silky softness, while polyester is a synthetic fibre that adds strength to the fabric.
Which fabric is the most breathable and best at absorbing moisture?
The most breathable and absorbent fabrics are cellulose fibres: modal, viscose and cotton. The main difference between them is how fast they dry:
- Modal and viscose: absorb moisture quickly and dry very fast, keeping you dry and cool throughout the night.
- Cotton: highly breathable and absorbs moisture well, but dries more slowly, so it can cling to the skin when damp.
- Polyester: absorbs almost no moisture and traps heat, so it is better suited to cooler environments.
If you want light coolness, modal or viscose is the best choice. If you prefer cosy warmth, go for cotton or polyester satin.
Modal or viscose: what is the real difference?
Modal and viscose belong to the same family of cellulose fibres, but they differ in production technology and durability. Modal is an improved type of viscose that is particularly resistant to moisture.
The biggest difference shows up in the wash: when wet, viscose loses some of its strength, so it needs gentler care. Modal handles washing more easily and keeps its original shape perfectly, even after many wash cycles.
When choosing pyjamas, the decision is simple: light, floaty viscose is ideal for summer heat, while modal is the best choice if you want an exceptionally soft set that withstands frequent washing.
Fabric texture and drape
Cotton and modal blends and polyester satin keep their original appearance the longest. Pure cotton withstands frequent washing but creases easily, and over time its colour may lose its original vibrancy. Viscose requires gentler care, while modal is considerably more durable.
A cotton and modal blend combines the best qualities of both materials: the strength of cotton with the softness and wash resistance of modal.
Polyester satin stands out for its practicality: it dries very quickly, does not crease and keeps its prints and colours for a long time.
Fabrics made from natural cellulose last longer with proper care:
- Wash at no higher than 30 °C;
- Choose a gentle or delicate programme;
- Dry flat.
Which fabric should you choose for the season and your sleeping habits?
When choosing pyjamas, consider two things: the time of year and how warm you like to sleep. The season helps you choose the fabric weight and style, while your personal sleeping habits determine the fibre itself.
- If you want to stay cool at night: opt for modal, viscose or cotton and modal blends. Lightweight shorts sets or short nightdresses are perfect for the warmer season.
- If you want more warmth: choose a denser cotton jersey or polyester satin, which helps retain body heat.
Remember that warmth comes not only from the fibre itself, but also from the fabric’s density and cut. Light, thin cotton is perfect for summer nights, while a denser long-sleeved set in the same cotton will keep you cosy in winter.
What does the label tell you about the fabric?
A garment label gives the most accurate information about the fabric, because labelling is governed by clear rules. Three key points are worth remembering:
- Fibre order: fibres in the composition are always listed in descending order by weight. For example, “60% viscose, 40% cotton” means the fabric will be dominated by the properties of viscose.
- “100%” labelling: this indicates a pure fibre, although a small amount of other fibres is permitted in production.
- Transparent composition: the exact composition must be clearly visible before purchase, including in an online shop.
For every product, Aruelle lists the exact composition in percentages, care instructions and information about its fabrics and certifications.
Frequently asked questions
What fabric is best for summer pyjamas?
Thin cotton, viscose or modal are great for summer, as these fabrics are breathable and dry quickly.
Is satin a material?
No, satin describes a weaving method that gives fabric its smoothness and subtle sheen. Viscose, cotton or polyester can all be woven in a satin weave, so it is always worth checking the garment’s composition.
What is the difference between viscose and modal?
Both fibres are made from wood cellulose, but modal is processed to be stronger when wet. Modal holds its shape better in the wash, while viscose stands out for its exceptional lightness and softness.
