Lycra is a kind of artificial elastic fiber, which was originally produced by DuPont company in the United States. Its extraordinary extension and recovery performance increase the value of the fabric, so the clothing will be more fit, comfortable and elegant. Lycra is a registered trademark of DuPont and a patented product. Because of its superior performance, many garments use lycra fabric to improve their wearability.

Many brands of clothing contain lycra fabric, and the performance depends on the ingredients contained in Lycra. Generally, the fabric of daily clothes contains Lycra 5% to 10%, while stockings, swimsuits and some sportswear have higher requirements, generally between 14% and 40%. The higher the lycra content, the better the performance and, of course, the more expensive. You must pay the patent fee to DuPont.

In addition, if you buy clothes containing Lycra, you must see whether there is a patented trademark of DuPont Lycra! Lycra content on the ingredient label is also an important reference.
