Quick answer: Mulberry silk is a natural protein fiber, while satin is a weave usually made from polyester.

Is satin the same as silk?
No, and the confusion costs brands. Silk is a natural fiber spun by silkworms, while satin is a weave structure often made from polyester or nylon. A product can be called satin yet contain no silk. Mulberry silk refers to silk produced by Bombyx mori silkworms fed on mulberry leaves, yielding long, fine filaments.

What should be confirmed before production?
