Satin is a weave, not a fibre, in which warp yarns float over several weft yarns before interlacing, which gives the face of the fabric its smooth, glossy surface. In Surat satin is usually woven from polyester filament and is available from light lining weights through dress and blouse weights up to heavy bridal and furnishing qualities. The same weave can be made in silk, viscose or acetate, so the fibre should always be stated alongside the word satin. Weight, usually given in grams per square metre, is the second thing a buyer needs to fix.
How the weave works
In a satin weave each warp yarn passes over four or more weft yarns and under one, and the interlacing points are spread out so they do not form a visible diagonal. The long floats lie flat and reflect light, which produces the sheen. The back of the fabric is duller because it shows mostly weft. Sateen is the reverse arrangement, with weft floats on the face, and is more common in spun cotton than in filament polyester.
Polyester satin is usually woven from fully drawn yarn, which is flat and smooth and gives the strongest sheen. A textured yarn in the weft gives a softer, more matte look that some buyers prefer for daywear.
Weights available
- Light lining satin, at the lower end of the weight range, used inside jackets, bags and dresses where a slippery surface is wanted.
- Dress and blouse satin, a medium weight with enough body for unlined garments and good drape for bias cutting.
- Bridal and heavy satin, often called duchess satin, which is dense, firm and holds structured shapes.
- Crepe-back satin, a double-faced fabric with a satin face and a crepe reverse, used where both sides may show.
- Stretch satin, woven with elastane in the weft for fitted garments and lingerie.
What to watch when buying
Satin shows faults easily because the float surface catches light, so slubs, broken filaments and weaving bars are more visible than on a crepe. It is also prone to snagging and to seam slippage, especially in lighter weights, so a buyer should ask for seam slippage test results rather than relying on hand feel. Colour matching across lots matters because the sheen changes how a shade reads under different light. Width is typically around 44 to 60 inches in Surat, and the heaviest weights may need units with looms set up for dense constructions.
Ask for the fabric to be properly heat set. Poorly set polyester satin can shrink and lose width at the garment maker's pressing stage, which shows up as a shortfall long after the rolls have been paid for.
How we help
We visit the weaving and process units making your satin and confirm the weight and construction against your reference. We audit the units, send sealed samples to an NABL-accredited lab for weight, seam slippage and colour fastness, inspect rolls before loading and supervise loading. Weekly updates keep you informed, and we hold one approved supplier plus one backup. If you are specifying satin for the first time, a free 20-minute sourcing review will help you set the right weight.
