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 .
Properties of synthetic fibers
Extraordinarily elastic spandex. The fabric, consisting of its fibers, stretches to five hundred percent of its length. This elasticity is manifested due to the chemical composition of the material. It consists of numerous polymer threads of two types. The first of them are amorphous and long. The threads of the second type are hard and short. All these properties and shows spandex. The fabric created from it is highly durable and stretches well.
Key Features of Spandex
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.
Fabrics containing synthetic polymer fiber are easy to clean. They hardly wrinkle and iron well. Some manufacturers who refer to their fabric as spandex are exaggerating. Such materials contain only a certain percentage of this synthetic fiber. However, this allows several times to increase the consumer properties of the fabric.
There are materials made entirely of spandex threads. To identify such materials for proper care, carefully study the label. The fabric, fully composed of spandex fibers, resembles soft rubber in its properties. This material does not crease, but the body fits like a second skin.
What is spandex used for?
Light and elastic fabric is used when sewing various clothes. As a rule, these are things that should not restrict the movement of its owner.
For example, a tracksuit. This fabric is used when sewing swimwear, bicycle pants, underwear, bras and stockings. Fancy dresses are also often sewn from material such as spandex. Fabric, the price of which is within 135 rubles per square meter, is purchased, as a rule, in wholesale warehouses.
