Spandex is nothing more than a synthetic light fiber. Use it in the manufacture of clothing. The main feature of things sewn with its use is their ability to reach.
The history of the appearance and composition of spandex
The first use of this synthetic fiber began in the fifties of the last century. It was intended to replace rubber. Gradually, new spheres of application were found for this fabric.
Spandex fabric (see photo below) is a synthetic polymer in its structure.
The fibers of this material are a long chain of polyglycol combined with diisocyanate. At the same time, eighty-five percent of polyurethane is in the composition of the synthetic polymer .

The fabric created from synthetic polymer threads can be stretched more than once. In this case, she will always return to its original shape and size. Spandex, the fabric of which is smooth and soft, is easily dyed. The color on the material lasts a long time. Spandex fiber fabric does not respond to human perspiration. Its distinctive feature is that it does not heat up. Spandex perfectly combines with a variety of materials. This allows the production of new types of fabrics.
Rarely found material consisting of one hundred percent spandex. Typically, this polymer fiber is added to cotton, linen, or synthetic materials. Spandex gives them extensibility and greater strength., , . . , , . . .
