Serger thread is finer than regular sewing machine thread, in order to avoid bulky seams. It must be smooth and consistent in diameter since it passes through so many guides in a serger. Serger thread should not leave a lot of lint, so that it does not clog the serger. Serger thread is sold on a large spool, called a cone, and generally has a length of 3000 yards. Serger thread can be made of cotton, polyester, nylon, or wooly nylon.
100% Polyester - Multi-use, the most common type.
Nylon - very strong; recommended for swimwear, lingerie, sportswear, elasticized fabric
100% Cotton - not quite as strong, use on woven materials or in the loopers, with polyester or nylon in the needles
Woolly Nylon - texturized, soft, and strong, can stretch & recover; comes in "kinked" or "flossy;" use for swimwear, lingerie, sportswear, elasticized fabric
