Satin refers to the weave of a fabric rather than the material. It typically has a glossy surface and a dull back, one of three fundamental types of textileweaves along with plain weave and twill. The satin weave is characterized by four or more fill or weftyarns floating over a warp yarn, four warp yarns floating over a single weft yarn. Floats are missed interfacings, for example where the warp yarn lies on top of the weft in a warp-faced satin. These floats explain the high luster and even sheen, as unlike in other weaves, the light reflecting is not scattered as much by the fibres. Satin is usually a warp-faced weaving technique in which warp yarns are "floated" over weft yarns, although there are also weft-faced satins. If a fabric is formed with a satin weave using filament fibres such as silk, polyester or nylon, the corresponding fabric is termed a satin, although some definitions insist that the fabric be made from silk. If the yarns used are short-staple yarns such as cotton, the fabric formed is considered a sateen. Many variations can be made of the basic satin weave, including a granite weave and a check weave. Satin is commonly used in apparel: women's lingerie, nightgowns, blouses, and evening gowns, but also in boxer shorts, shirts and neckties. It is also used in the production of pointe shoes for use in ballet. Other uses include interior furnishing fabrics, upholstery, and bed sheets.
Fabrics created from satin weaves are more flexible, with better draping characteristics than plain weaves, allowing them to be formed around compound curves, which is useful in carbon-fiber composites manufacturing. In a satin weave, the fill yarn passes over multiple warp yarns before interlacing under one warp yarn. Common satin weaves are:
4-harness satin weave, also called crowfoot satin, in which the fill yarn passes over three warp yarns and under one warp yarn. It is more pliable than a plain weave.
5-harness satin weave ; the fill yarn passes over four warp yarns and then under one warp yarn.
8-harness satin weave, in which the fill yarn passes over seven warp yarns and then under one warp yarn, is the most pliable satin weave and forms most easily around compound curves.
Baronet or baronette - has a cotton back and a rayon or silk front, similar to georgette.
Charmeuse - is a lightweight, draping satin-weave fabric with a dull reverse.
Double face - satin is woven with a glossy surface on both sides. It is possible for both sides to have a different pattern, albeit using the same colors.
Duchess satin - is a particularly luxurious, heavy, stiff satin.
