Stretch fabric is a very common type of textile, and it is common to use casual sportswear fabric. There are many types of elastic fabrics. In the early years, elastic cotton was used. With the popularization of man-made fibers, rayon elastic fabrics and Tencel elastic fabrics were also widely popular. In recent years, there are elastic fabrics such as acetate polyester and acetate brocade.

  The basic elastic cotton fabric is made of a hollow crimped fiber and a low-melting fiber as raw materials, and the fibers are three-dimensionally distributed through a certain technological process. Its composition is generally 98% cotton and 2% elastic. DuPont Lycra is a man-made elastic fiber with the best elasticity. It can extend to 4 to 6 times its original length. It has excellent stretch and is suitable for blending with various fibers. Lycra stretch fabric with chlorine-resistant ingredients will make the swimsuit have a longer life than ordinary swimsuits.

  Third, although the texture of nylon fabric is not as solid as that of Lycra elastic fabric, its elasticity and softness are comparable to that of Lycra. Currently the most commonly used fabric for swimwear, suitable for mid-priced products. The last commonly used polyester fabric is a one-way, two-way stretch fabric. Due to the limited elasticity, it is mostly used in swimming trunks or women's swimming split two-section fabrics, which can be partially spliced ​​or applied in a low unit price strategy.
