Sateen

Sateen is a fabric made using a satin weave structure, but made with spun yarn instead of filament yarn. It is a cotton or other non-silk fabric that has the characteristics of silk satin but is less expensive.

The dense weave, sheen and softer feel of sateen is produced through the satin weave structure. Standard plain weaves use a one-over, one-under structure. For a satin weave, warp yarns are floated over weft yarns, for example four over and one under (for a five-harness satin weave). In a weft-faced satin or sateen, the weft yarns are floated over the warp yarns. This weave structure is prone to fraying and is less durable than plain weave fabrics.

Some sateen is mercerized, a chemical process that makes fibers softer, smoother, and more resilient.
