Satin is a weaving technique applied to many types of fabric including polyester, nylon, acetate, rayon, and silk. The shine and softness of the fabric is derived from the weave. When this technique is applied to cotton, the fabric is referred to as sateen. Satin Serenity uses a heavy weight Peau de Soie (meaning skin of silk) 100% polyester satin which is not as shiny or slippery as most satins found in fabric and department stores. This type of satin is also very durable, easy to care for, maintains its color, and has minimal wrinkling.
