What is spandex yarn fabric
Spandex yarn is a man-made fiber, its scientific name is polyurethane fiber, and it is an elastic fiber with very good elasticity. It can be stretched 6 to 7 times under normal conditions, and it will return to its original state when the tension disappears.
1. The elasticity of spandex yarn is very high. Generally, 100% polyurethane is not used in general products, but 5~30% is mixed in the fabric.
2. The core-spun elastic fabric is made of polyester and other cortex, which has good adaptability to the body and is very suitable for tights without feeling of pressure.
3. The appearance style and wearing performance of the spandex elastic fabric are close to those of similar products covered with the outer fiber fabric.
Application of spandex yarn
1. The grade of fabrics and clothing mainly depends on the technology of textile and clothing making, and has little to do with the raw material fibers.
2. Nylon or spandex is generally not used alone in underwear fabrics, but is often blended and interwoven with other fibers. Especially spandex, the general content is about 5%.
Because spandex yarn has very good elasticity, it is widely used to make underwear, casual wear, sportswear, pantyhose and others. In medicine, it can be used to make bandages, surgical protective clothing, etc., and it is also the fabric for short sleeves for cycling and wrestling vests.
