You take your silk pillowcase off the drying rack and it looks nothing like it did in the box. There are creases across it, a line where it hung, and a few folds that seem set in. This is normal. Silk is a fine natural fibre, and it wrinkles when it dries.
The good news is that silk also lets go of wrinkles easily, as long as you use moisture and low heat instead of force.
The short answer: steam is the gentlest way. If you prefer an iron, use the lowest or silk setting on the reverse side while the fabric is still slightly damp, and keep the iron moving.
Why silk wrinkles in the first place
Silk fibres are fine and smooth, and they take the shape they dry in. If a pillowcase dries bunched up, twisted or folded over a thin line, it keeps those folds. Wringing it out after washing makes this worse, because it presses sharp creases into wet fabric.
Most wrinkles are easier to prevent than to remove, so it helps to look at how you dry your silk before you reach for the iron.
Three safe methods, compared
| Method | Best for | Effort |
|---|---|---|
| Garment steamer | Pillowcases, masks, bedding, anything delicate | Low |
| Cool iron on damp silk | A crisp, flat finish on pillowcases and sheets | Medium |
| Steamy bathroom | Light creases, travel, no equipment | Very low |
How to steam silk
- Hang the piece on a hanger or over a clean rail so it falls straight.
- Hold the steamer a short distance from the fabric. It should not press against the silk.
- Move slowly from top to bottom and let the steam do the work.
- Smooth the fabric gently with a clean hand as you go.
- Leave it to hang for a few minutes until it is fully dry before you put it on the bed.
Steam relaxes the fibres without flattening them, which is why the sheen looks its best after steaming.
How to iron silk
An iron gives a flatter, more polished result, and it is safe if you are careful.
- Check the care label first.
- Turn the piece inside out so you iron the reverse side.
- Set the iron to its lowest or silk setting.
- Iron while the silk is still slightly damp. If it has dried completely, lay a clean, damp cotton cloth over it.
- Keep the iron moving. Do not rest it in one place.
- Avoid ironing over zippers and seams with pressure, which can leave an imprint.
A thin white cotton cloth between the iron and the silk is a good habit even when the fabric is damp. It protects the surface from shine marks.
No steamer and no iron
Hang the silk in the bathroom while you take a hot shower, away from the water itself. The steam in the room softens light creases. Smooth the fabric with your hands afterward and let it air for a while.
This is the easiest method when you travel. It will not remove deep folds, but it takes care of most of what a suitcase does.
What to avoid
- High heat. A hot iron can scorch silk or leave a permanent shiny patch.
- Spraying water on dry silk. Drops can dry into water marks. Dampen the whole piece evenly, or use a damp cloth.
- The tumble dryer. It is sometimes suggested as a shortcut for wrinkles. Heat and tumbling are hard on silk, and we explain why in can you put silk in the dryer.
- Wrinkle-release sprays and starch. They are made for sturdier fabrics and can leave a residue or a stain.
- Pulling and stretching. Tugging wet silk to flatten it can distort the shape.
How to prevent wrinkles next time
Most of the work happens right after washing. Follow a gentle routine, as in our guide on how to wash and care for your silk pillowcase, and then:
- Press the water out between two towels instead of wringing.
- Shake the piece out and smooth it flat with your hands while it is wet.
- Dry it flat or over a wide, padded rail in the shade, not over a thin line.
- Put it on the pillow while it is just dry. The pillow fills the case and smooths it.
- Store spare silk loosely folded or rolled, not pressed under heavy linen.
Heavier silk tends to hang better and crease a little less than lighter silk. That is one of the practical differences between weights, which we cover in what momme means in silk.
Questions people ask
Do I have to iron a silk pillowcase?
No. A few soft creases do not change how silk feels, and most of them relax after a night or two on the pillow. Ironing or steaming is only about how it looks.
Can I use a hair dryer?
It is better not to. A hair dryer gives dry, concentrated heat, which is the opposite of what silk needs. Steam is kinder.
Will a steamer leave water marks?
It can if the steamer spits water. Let it heat fully before you start, keep it a little away from the fabric, and use clean water.
A smooth bed starts with fabric that is cared for gently. If you are choosing your first piece, see our silk pillowcases, or the Mulberry Silk Bedding Set if you want the whole bed in silk.
