Satin is a weave that typically has a glossy surface and a dull back. It is a warp-dominated weaving technique that forms a minimum number of interlacings in a fabric. If a fabric is formed with a satin weave using filament fibers such as silk, nylon, or polyester, the corresponding fabric is termed a satin.

A satin-woven fabric tends to have a high luster due to the high number of floats on the fabric. Floats are missed interlacings, where the warp yarn lies on top of the weft yarn, or vice versa. The floats tend to make the fabric look glossier as well as give it a smoother surface.
