Satin is the weave in a Satin structure. The satin weave (or atlas structure) is a weaving technique, wherein the intersections of the warp and weft yarns are evenly dispersed, it is a warp-dominated weaving technique that forms a minimum number of interlacings in a fabric. The satin effect is formed by the weft threads when they cover the points of attachment. With this technique, yarns can be woven quite densely, which makes the fabric low in density, light and comfortable. If glossy and matte weft warp threads are used, the backside of the fabric will be dull, but front side will be shiny because of the loose weft threads. This gives the fabric a luxurious look. The satin word comes from the Italian word for silk: seta. Satin is not only made of silk, but also, for example, cotton and viscose. Satin shimmers and shines and takes dyes very well. Satin is commonly used in apparel: satin baseball jackets, athletic shorts, women's lingerie, nightgowns, blouses and evening gowns, but also in some men's boxer shorts, shirts and neckties. It insulates very well, which makes it warm in the winter and cool in the summer. Other applications include interior furnishing fabrics, upholstery, and bed sheets.
