Satin is a weave with long floats and widely separated, non-adjacent interlacings, giving a smooth, lustrous face dominated by either warp (satin) or weft (sateen).
In detail
In a satin, each yarn floats over several crossing yarns and interlaces only once per repeat, and neighboring interlacings are scattered rather than stepped in a diagonal. The binding points are hidden under adjacent floats, so the face looks unbroken. Light reflects specularly from the long parallel floats, which is why filament yarns such as silk or polyester in satin appear glossy. Warp-faced satins show warp floats; sateen, often cotton, is weft-faced.
The science and numbers
A satin is defined by its repeat, the number of ends and picks before the pattern recurs, and its move or counter, the step between successive interlacings. The smallest regular satin has a five-end repeat; eight-end satins are common and are sometimes written 8/3 to show the move. A regular satin needs a move greater than one, less than the repeat minus one, and sharing no common factor with the repeat, so that interlacings never touch. With only one interlacing per yarn per repeat, crimp is low and yarns pack densely. Studies of weave structure report that satin fabrics differ measurably in stiffness and tensile behavior from plain and twill fabrics made from the same yarn, consistent with float length.
A practical example
Compare a silk charmeuse and a cotton sateen sheet. Both feel smooth and reflect light, but in the charmeuse the floats run lengthwise in the warp, while in the sateen they run crosswise in the weft. Rubbing a fingernail gently along the float direction feels slicker than across it. The long floats that give this smoothness are also why a rough ring can snag the face.
What to distinguish
Satin names a structure, not a fiber: satin can be silk, polyester, acetate or cotton. The shine comes largely from structure and filament yarns, so a lustrous fabric is not necessarily silk. Long floats trade durability for smoothness and are more prone to snagging and abrasion. Sateen and satin are related but face in different directions.
Origins and history
Satin requires at least five sheds, so it demands more loom shafts or a figure-harness mechanism than plain or twill. Historically it is closely associated with silk filament, whose long smooth fibers make the most of long floats, and later with lustrous manufactured filaments and mercerized cotton sateens. This edition did not verify etymological claims about the word satin and so does not repeat them.
