Silk is usually not prone to wrinkles. However, it tends to become wrinkled from the wash, or it has folded deep folds after it comes back from the dry cleaners. You are not allowed to iron silk with a hot iron or apply any kind of direct heat for that can damage the silk, thus it is really hard to get wrinkles out of silk. If your clothes dryer has a very low heat-free setting, you can safely use it to remove wrinkles. Steps are shown below.
First, place silk fabric in a drier, and then set the dryer to lowest heat setting or preferably to a no-heat setting. (This can be labeled as “Cool”, “No Heat”, or “Air Fluff”.)
Always check the silk in the dyeing machine to make sure it is dry and the wrinkles disappear.
