Lycra fabric introduced.

Lycra fabric is a fabric made of spandex fiber (the abbreviation of spandex polyurethane fiber), which is also called "easel" in Cantonese (the Cantonese pronunciation of Lycra) and sometimes directly called "spandex cloth" in Chinese mainland. LYCRA is a transliteration of the English word Lycra. Bayer in Germany was successfully developed in 1937, and DuPont in the United States began production in 1959. It is the registered trademark of DuPont spandex fiber, which can greatly improve the elasticity and extensibility of the fabric. The good resilience of spandex after stretching is its greatest advantage. Different from the traditional elastic fiber, its ductility can reach 500% and it can be restored to its original state. In other words, this kind of fiber can be stretched very easily, but after recovery, it can cling to the surface of human body and has little binding force on human body. Lycra fiber can be used with any fabric, which is called "friendly" fiber, and its good quality has been recognized by peers. As long as Lycra is used, a triangle tag will be hung on the clothes, and this tag has become a symbol of high quality. Lycra is the brand name of NVIDIA, the largest comprehensive fiber and polymer company in the world (formerly a wholly-owned subsidiary of DuPont, which was acquired by Koch Industrial Group in 2004 for $4.4 billion). Invista occupies a monopoly position in the field of spandex, and Lycra is synonymous with almost all spandex yarns. It completely replaces the traditional elastic rubber thread. Lycra is almost an essential component in clothes with special requirements, such as gymnastics clothes and swimming suits. It can show your curves, and your limbs can stretch freely without oppression. Lycra is not only widely used in daily clothes, but also a pet in a popular kaleidoscope made by fashion designers. Lycra is therefore called magic fiber by happy people.
