Now we all love beauty and attach importance to the maintenance of body shape. Many people will choose some elastic clothes to highlight the curve when they have attractive body shape. Elastic jeans have always been the popular style of people.
In recent years, the fabrics of some casual clothes are elastic, comfortable and casual, and are very popular with young people.
Why do these fabrics have such remarkable elasticity?

If you observe carefully, you will find that the elasticity of all elastic fabrics is horizontal, which is equivalent to the weft direction of the cloth surface, while there is no elasticity in the longitudinal direction.
The subtlety of this is that weft yarn uses a kind of yarn called elastic core-spun yarn. Elastic core-spun yarn is a special type of yarn. It uses about 4% - 8% spandex elastic yarn as the core, and about 90% cotton yarn is wrapped around the outside of the spandex yarn in a spring shape. Although the cotton yarn has no elasticity, when the spandex filament stretches, the cotton yarn stretches like a spring, so the fabric has elasticity in the transverse direction.
It can be seen that spandex plays a crucial role in this process. Among the elastic fabrics, spandex only accounts for about 5% of the total amount of all fibers and can have significant elasticity.
Now we understand why this fabric has such remarkable elasticity?
