Satin dates back to the medieval China, where it was made exclusively with silk. The weave originated in the Chinese port city of Quanzhou, which was called Zaitun in medieval Arabic, hence the name satin today.
Is satin natural or synthetic?
Satin is a finish of a weave and not a natural fibre like silk. Traditionally satin will have both a glossy side and a dull side. It is made using combinations of other fabrics like nylon, rayon, polyester, and even silk. Most commonly a satin finish is used to make cheap man-made fibres look and feel more luxurious.
What is satin normally made from?
If you're producing a satin weave using filament fibres such as silk, nylon or polyester, then your resulting fabric is a Satin. However, there's some definitions that insist a Satin fabric can only be made from silk.
