Sateen, not to be confused with the material satin, is a type of weave, with a satin-like finish, often found in bed sheets.

Sateen is usually applied to cotton, or sometimes rayon. Better qualities are mercerized to give a higher sheen. Some are only calendered to produce the sheen but this disappears with washing and is not considered genuine sateen. Sateen may be bleached, dyed, or printed.

Sateen produces the sheen and softer feel through the use of a different structure in the weaving process. The sateen structure is four over, one under, placing the most threads on the surface, making it extremely soft, though slightly less durable than other weaves.
