Your nylon shorts came out wrinkled from the wash—and you’re tempted to iron them. But nylon is synthetic and sensitive to heat. So is ironing safe?
Yes, you can iron nylon shorts—but only on the lowest heat setting and with extreme care. Always use a pressing cloth and avoid direct heat, or you risk melting or damaging the fabric.
I’ve seen many customers ruin nylon garments by using a hot iron. Nylon requires a different approach than cotton or linen. With the right steps, though, you can smooth it out safely.

Why is ironing nylon risky?
Nylon is a plastic-based synthetic fiber—and heat is its enemy.
Nylon melts at relatively low temperatures. If your iron is too hot or you skip a pressing cloth, the fabric can scorch, shrink, or become shiny.

Nylon’s heat sensitivity
| Temperature Level | Nylon Reaction |
|---|---|
| High heat (cotton/linen setting) | Fabric may melt or burn |
| Medium heat (wool/poly setting) | Can cause shine or shrink |
| Low heat (synthetic/nylon setting) | Safe with pressing cloth |
Always check the care label symbols—many nylon blends aren’t meant to be ironed at all[^1].
How to safely iron nylon shorts?
If you must iron them, take these steps to avoid damage.
Use your iron’s lowest setting, turn the shorts inside out, place a cotton cloth on top, and never use steam directly. Keep the iron moving gently—don’t press too long on one spot.
Step-by-step ironing guide:
- Set your iron to “synthetic” or “nylon” – usually the lowest temperature
- Turn the shorts inside out – prevents shine or marks on the outside
- Lay a thin cotton cloth on top – acts as a heat buffer
- Gently press and lift—don’t slide – nylon can stretch under pressure
- Let the shorts cool flat – this helps set the smooth shape
If the label says “do not iron,” use a hand steamer like this one from Conair, or hang them in the bathroom during a hot shower to relax wrinkles[^2].
Are there better ways to remove wrinkles from nylon?
Yes—steaming is safer and often more effective.
Use a handheld steamer or steam setting on your iron (without touching the fabric) to gently release wrinkles from nylon shorts. Air drying them flat or hanging them near steam can also help.
Wrinkle removal alternatives
| Method | Effectiveness | Fabric Safety |
|---|---|---|
| Handheld steamer | ✅✅✅ | ✅✅✅ |
| Hanging in steam room | ✅✅ | ✅✅✅ |
| Dryer (low heat, with towel) | ✅ | ✅ if short duration |
| Ironing (low heat + cloth) | ✅ | ⚠️ Use with care |
Nylon is quick-drying and low-absorbent, so wrinkles tend to soften naturally—especially if hung properly after washing[^3].
Conclusion
Yes, you can iron nylon shorts—but only on the lowest heat setting, with a pressing cloth, and extra caution. To avoid damage, steaming or air-drying methods are safer and more effective for removing wrinkles from synthetic fabrics like nylon.
[^1]: Many nylon care labels include a crossed-out iron symbol. This means ironing is not recommended and alternative methods like steaming should be used.
[^2]: Steaming relaxes synthetic fibers gently and doesn’t risk melting the surface. Great for delicate blends.
[^3]: Nylon is hydrophobic, so moisture doesn’t absorb but instead sits on the surface—making it ideal for fast wrinkle release when hung properly.
