Sometimes satin has chemical stabilizers in it to make it easier to work with.
To test your particular piece of fabric, take a 4″ square scrap and either serge the edge or otherwise stitch around the square to keep it from fraying.
Hand-wash it in mild soap and blow dry it with your hairdryer on a low setting.
The answer will be in your hands!
Hope this helps – good luck! ;D
