Spandex, nylon, and polyester are the most commonly used materials for swimwear, and manufacturing processes such as jacquard and hollowing cannot be separated from these three types of elastic characteristics. However, currently, spandex is the main material for swimwear in the market, and many of them incorporate special properties such as UV resistance, chlorine resistance, and waterproofing.

Spandex fabric: A type of artificial elastic fiber, usually composed of multiple filaments. The fabric with the best elasticity can extend 6-7 times, has excellent ductility, and has a strength 23 times higher than latex silk. It is suitable for blending with various fibers, can strengthen the texture and sagging, and has excellent acid and alkali resistance and wear resistance. The international standard for the content of spandex yarn is around 18%, which makes swimwear very elastic. The popular spandex fabric with chlorine resistant ingredients now provides swimwear with a longer lifespan than ordinary swimwear materials.

Nylon fabric: Although the texture is not as strong as spandex fabric, its elasticity and softness are evenly matched. Many mid priced swimwear products often use nylon fabric.

Polyester fabric: This is a one-way, two-way stretch elastic fabric, which is mostly used in swimwear or split half swimwear due to elastic limitations. It is not suitable for one-piece styles and can also be partially cut and used in swimwear
