Sewing thread has a variety of descriptions. We generally refer to it as, "two or more yarns twisted together to form a single strand in a plied or corded construction".
However, these days there are other 'Continuous Filament' constructions manufactured using technologies, like intermingling, texturising and air jet texturising which can produce a thread of a single ply construction.
Coats produces many different threads and this will be explained within this technical bulletin.
Most sewing threads today are based on synthetic materials, such as polyester or nylon, which have, to a large extent replaced the use of natural fibres like cotton and linen that used to be the material of choice.
Handicraft threads are still predominantly made out of cotton, especially when the handicraft work is done by hand. However, if the handicraft effect is being created by a machine, (as in the case of embroidery of logos), then synthetic threads are rapidly replacing cotton and rayon threads.
