Short answer
Modal is similar to cotton in several everyday ways: it is breathable, absorbent and comfortable against the skin, and it is used for many of the same things, such as T-shirts, underwear, loungewear and bedding. But modal is not cotton. It is a regenerated cellulose fiber, typically made from beech wood pulp, so it is usually described as semi-synthetic. Compared with cotton, it generally feels smoother and drapier, and it tends to resist shrinking and fading better than basic rayon.
What modal is
Modal belongs to the rayon family. Like viscose, it starts as dissolved plant cellulose that is spun into fiber, but it is made with a modified process that gives a stronger fiber, particularly when wet. This is why modal is sometimes called a high-wet-modulus rayon. For the wider family, see our pillar article on whether viscose is breathable.
How modal and cotton are similar
- Cellulose-based. Both are made of cellulose, which supports their absorbent, plant-like comfort.
- Breathable. Both let moisture and air move reasonably well and suit warm-weather clothing.
- Absorbent. Both take up sweat. Modal is often described as absorbing as much as or more than cotton, but precise comparisons depend on the fabric, so treat claims with a number attached with some caution.
- Common uses. T-shirts (see types of cotton for T-shirts), underwear, pajamas, sheets and casual wear.
How they differ
| Feature | Modal | Cotton |
|---|---|---|
| Origin | Regenerated cellulose, commonly from beech pulp | Natural fiber from the cotton plant |
| Feel | Silky, smooth, fluid drape | Can be crisper at first, softens with use |
| Shrinkage | Generally lower than basic viscose; can still shrink | Can shrink, especially the first wash |
| Pilling and fading | Often resists fading, may pill depending on knit | Varies by quality and staple length |
| Durability | Good but less sturdy than strong cottons, especially in rough use | Often very durable |
| Cost | Typically higher than plain cotton | Wide range |
These are general tendencies, not guarantees. A high-quality combed cotton can feel extremely soft, and a loosely knit modal can pill.
Is modal fabric made of plastic?
No. Modal is made from cellulose from wood, not from petroleum, so it is not plastic in the way that polyester or nylon are. It is, however, chemically processed, which is why it is called semi-synthetic or regenerated rather than natural. The finished fiber is also usually described as biodegradable under suitable conditions, although dyes, finishes and blended synthetic fibers can affect that. If you want to see how it compares with an actual synthetic, read modal vs polyester.
Is modal fabric 100% cotton?
No, modal is a separate fiber. However, many garments combine them. Cotton-modal blends, especially in T-shirts, aim for the structure and familiarity of cotton with the smoothness and drape of modal. Check the label for the actual proportions, as they vary by brand.
Can you put modal in the dryer?
Check the care label first. In general, modal is more tolerant of washing than basic viscose, and many modal garments are labeled machine washable on gentle or cool cycles. Heat is the main risk for any regenerated cellulose fiber, so low heat or air drying is the safer choice, particularly for knits and blends. Tumble drying on high can contribute to shrinkage and a worn look. Cotton has its own shrinkage habits, covered in does cotton shrink in the wash, and modal’s give is covered in does modal fabric stretch. Compared with ordinary rayon, which often needs more careful treatment, see rayon vs cotton for the care differences.
What fabric is most similar to modal?
Other rayon-family fibers are the closest relatives: viscose, which is similar in feel but usually less stable, and lyocell, which is also smooth and typically strong. See our lyocell care guide for more. Cupro and fine pima or Supima cotton jersey can also feel comparable depending on the construction.
Which should you choose?
- Choose modal if you want a softer, silkier feel, good drape and a smooth surface for underwear, tees and loungewear.
- Choose cotton if you prioritize a natural fiber, a lower price, a crisper structure or maximum everyday durability.
- Choose a cotton-modal blend if you want a compromise, and follow the care label.
