S
Sailcloth
Any heavy, plain-weave canvas fabric, usually made of cotton, linen, polyester, jute, nylon, etc. that is used for sails and apparel (i.e. bottomweight sportswear).
Saran Fiber
A manufactured fiber which has an excellent resistance to sunlight and weathering, and is used in lawn furniture, upholstery, and carpets.
Sateen Fabric
A fabric made from yarns with low luster, such as cotton or other staple length fibers. The fabric has a soft, smooth hand and a gentle, subtle luster. Sateen fabrics are often used for draperies and upholstery.
Sateen Weave
A variation of the satin weave, produced by floating fill yarns over warp yarns.
Satin Fabric
A traditional fabric utilizing a satin weave construction to achieve a lustrous fabric surface. Satin is a traditional fabric for evening and wedding garments. Typical examples of satin weave fabrics include: slipper satin, crepe-back satin, faille satin, bridal satin, moleskin, and antique satin.
Satin Weave
A basic weave, characterized by long floats of yarn on the face of the fabric. The yarns are interlaced in such a manner that there is no definite, visible pattern of interlacing and, in this manner, a smooth and somewhat shiny surface effect is achieved. The shiny surface effect is further increased through the use of high luster filament fibers in yarns which also have a low amount of twist. A true satin weave fabric always has the warp yarns floating over filling yarns.
Seersucker
A woven fabric which incorporates modification of tension control. In the production of seersucker, some of the warp yarns are held under controlled tension at all times during the weaving, while other warp yarns are in a relaxed state and tend to pucker when the filling yarns are placed. The result produces a puckered stripe effect in the fabric. Seersucker is traditionally made into summer sportswear such as shirts, trousers, and informal suits.
Selvage or Selvedge
The thin compressed edge of a woven fabric which runs parallel to the warp yarns and prevents raveling. It is usually woven, utilizing tougher yarns and a tighter construction than the rest of the fabric.
Serge
A fabric with a smooth hand that is created by a two-up, two-down twill weave.
Serging
An overcasting technique done on the cut edge of a fabric to prevent raveling.
Shantung
A medium-weight, plain weave fabric, characterized by a ribbed effect, resulting from slubbed yarns used in the warp or filling direction. End-uses include dresses and suits.
Sharkskin
A hard-finished, low lustered, medium-weight fabric in a twill-weave construction. It is most commonly found in men's worsted suitings; however, it can also be found in a plain-weave construction of acetate, triacetate, and rayon for women's sportswear.
Silk
A natural filament fiber produced by the silkworm in the construction of its cocoon. Most silk is collected from cultivated worms; Tussah silk, or wild silk, is a thicker, shorter fiber produced by worms in their natural habitat. All silk comes from Asia, primarily China.
Sisal
A strong bast fiber that originates from the leaves of the Agave plant, which is found in the West Indies, Central America, and Africa. End-uses include cordage and twine.
Solution-dyed
A type of fiber dyeing in which colored pigments are injected into the spinning solution prior to the extrusion of the fiber through the spinneret. Fibers and yarns colored in this manner are color-fast to most destructive agents.
Spandex Fiber
A manufactured elastomeric fiber that can be repeatedly stretched over 500% without breaking, and will still recover to its original length.
Spinneret
A metal nozzle type device with very fine holes used in the spinning process of manufactured fibers. The spinning solution is forced or extruded through the small holes to form continuous filament fibers. The holes in the spinneret can vary in diameter to produce fibers of various denier.
Spot Weave
A woven construction in which patterns are built in at spaced intervals through the use of extra warp and/or extra fill yarns are placed in selected areas. These yarns are woven into the fabric by means of a dobby or Jacquard attachment.
Spun Yarn
A yarn made by taking a group of short staple fibers, which have been cut from the longer continuous filament fibers, and then twisting these short staple fibers together to form a single yarn, which is then used for weaving or knitting fabrics.
Staple Fibers
Short fibers, typically ranging from 1/2 inch up to 18 inches long. Wool, cotton, and flax exist only as staple fibers. Manufactured staple fibers are cut to a specific length from the continuous filament fiber. Usually the staple fiber is cut in lengths ranging from 1-1/2 inches to 8 inches long. A group of staple fibers are twisted together to form a yarn, which is then woven or knit into fabrics.
Surah
A light weight, lustrous twill weave constructed fabric with a silk-like hand. Surah is the fabric of ties, dresses, and furnishings. It is available in silk, polyester, and rayon.
