Spandex yarn is a man-made elastic fiber developed. It is a manufactured texture material with elastic properties of the sort referred to nonexclusively as “Elastic Yarn”. It is highly elastic and can be stretched 6-7 times, but it can quickly return to its initial state with the loss of tension. Its molecular structure is a chain like, soft and extensible polyurethane, which is connected with hard chain segments to enhance its characteristics.
Spandex has excellent elasticity. And its linear density is finer, and it is more resistant to chemical degradation. Spandex has good acid and alkali resistance, sweat resistance, seawater resistance, dry cleaning resistance, and wear resistance.
Spandex is generally not used alone, but is added in small amounts to fabrics. This type of yarn has both rubber properties and yarn properties, and is mostly used for core yarns with spandex as the core, called elastic core yarns.
Spandex yarn is ordinarily used in athletic or dynamic dress. Spandex as an attire material is fetishized by a few people, maybe on the premise that the piece of clothing structures a “moment skin” that goes about as a fetishistic surrogate for the wearer’s own particular skin.
