High stretch white spandex yarn

Spandex covered yarn is an elastic yarn formed by covering spandex filaments with filaments or short fiber yarns in a spiral manner. Spandex core-spun yarn is a yarn spun with spandex yarn as the core and wrapped with one or several non-elastic short fibers. The core filament of the core-spun yarn is surrounded by the outer fiber, and the two are tightly combined. The core filament and the outer fiber have the same twist. It has three notable features: first, it has the same feel and appearance as the outer fiber (cotton, wool, polyester, cotton, etc.), and the outer sheath composed of natural fibers has good moisture absorption; the second is good elasticity;
Compared with other elastic yarns, the spandex core-spun yarn has a remarkable feature that the core yarn is not exposed when the yarn is stretched.

Compared with other types of stretch yarns, the strength of core-spun yarns is relatively low. Under normal circumstances, the strength of a single yarn is only equivalent to 80% to 90% of the yarn of the same specification wrapped fiber alone. The core-spun yarn is the first to break the outer fiber, and the strength formed by the outer fiber is the strength of the core-spun yarn. Spandex yarn is a low-strength and high-stretch filament. It does not contribute to the strength of the yarn in the core-spun yarn, but instead destroys the cohesive force between the fibers. Therefore, the higher the spandex content, the lower the strength of the core-spun yarn. It has a wide range of uses and can be used as a swimming suit due to its strong flexibility. Diapers; strong resilience, can be used as underwear. Outerwear; strong holding power, can be used as tight underwear. Pantyhose; strong formability, can be used as outerwear, etc.
