Spandex yarn and elastic fiber also belong to synthetic fiber, medium polyurea fiber, and middle section polyurea fiber. It has a wide range of uses and can be used as a swimming suit due to its strong flexibility. Diapers; strong resilience and can be used as underwear. Outerwear; strong holding power, can be used as tight underwear. Pantyhose; strong formability, can be used as outerwear, etc. It is used to combine with other fibers to form other yarns or cloths. It has high elasticity, resilience, retention, and makes the fabric straight. Stretching and quickly returning to shape;
Spandex fiber is more difficult to be made into high-count yarn, because the general spandex yarn is core-spun yarn, that is, a layer of short cotton yarn fiber is wrapped around the spandex filament fiber, while the ordinary cotton yarn is directly “twisted” into the yarn by the short cotton yarn fiber. String. Therefore, high-count spandex yarn is more difficult to spin.
The soft segment part of the spandex fiber chain structure has two types: polyester and polyether, which are divided into polyester spandex and polyether spandex. Generally, polyether spandex has a lower glass transition temperature and better elasticity than polyester spandex. Spandex can be directly used to weave stretch fabrics in the form of bare silk, or it can be processed into a certain form of stretch yarn and then used to weave stretch fabrics. Among them, there are three most widely used forms: spandex core-spun yarn, spandex twisted yarn and spandex covered yarn.
The processing principles of the three kinds of elastic yarns are different, which determines that their fiber structure is quite different, which is the fundamental factor that affects the performance of the yarn. Spandex core-spun yarn can be spun by ring spinning, vortex spinning, electrostatic spinning, etc. The most widely used method is ring spinning. Spandex twisted yarn is also called plied yarn, which is processed by refitting on a twisting machine.
