The biggest feature of Lycra stretch fabric is high elasticity, known as the elastic fiber, which can stretch 4-7 times the length. Almost all sports fabrics in the world today use spandex. Especially gym suits and swimming suits. Lycra fabric is a fabric made of spandex fiber (short for Spandex polyurethane fiber), which is also called “pull frame” (the Cantonese pronunciation of Lycra) in Cantonese areas.

In the Mainland, it is sometimes called “spandex cloth” directly. “Lycra” is the transliteration of the English word LYCRA. It was successfully researched by Bayer in Germany in 1937, and DuPont began production in 1959. It is a registered trademark of DuPont spandex fiber, which can greatly improve The elasticity and extensibility of the fabric, and the good recovery of spandex after stretching are its biggest advantages. The difference from traditional elastic fiber is that it can stretch up to 500% and can be restored to its original shape.

In other words, this kind of fiber can be stretched very easily, but it can stick to the surface of the human body after recovery, and the restraint force on the human body is very small. Lycra fiber can be used with any fabric. It is called “friendly” fiber, including wool, hemp, silk and cotton, to increase the close-fitting, elastic and loose nature of the fabric, and it feels more flexible when moving. Moreover, Lycra is different from most spandex yarns. It has a special chemical structure and will not grow mold in a humid and heat sealed space after being wet. Its good quality is recognized by peers. At present, as long as the clothing that adopts Lycra will be hung with a triangle tag, this tag has also become a symbol of high quality.
