Lycra fabric, also known as spandex fabric, is a fabric product made of spandex fiber as the main raw material. Lycra originated in Germany and is a new type of chemical fiber developed by Bayer Company in Germany. 1959, DuPont registered spandex fiber as its own trademark for mass production, and quickly won the initiative in market competition. Lycra has also become an indispensable element in all kinds of fabric products with its excellent elasticity, which is deeply loved by customers. Lycra, as the trade name of spandex fabric, has developed from a sub-brand of DuPont Company in the United States to a world-famous chemical fiber. This process is very rapid. Nowadays, Lycra has become synonymous with almost all spandex fibers and plays an important role in various fields. High-quality lycra fabric is mainly used to make gymnastic clothes and swimsuits. Its excellent characteristics create an ideal platform for designers' inspiration and become one of the popular fabrics in the clothing field.
