DuPont Lycra is an artificial elastic fiber with the best elasticity and stretchability, suitable for blending with various fibers, and can enhance the advantages of texture sagging and wrinkle resistance. DuPont Lycra swimsuits containing chlorine resistant ingredients have a longer lifespan and are often suitable for one-piece swimsuits.

Nylon fabric belongs to the mid price range, and compared to DuPont Lycra fabric, it lacks solidity, but its elasticity and softness are on par. It is currently the most commonly used fabric for swimwear, suitable for mid-range products.

Polyester fabric is an elastic fabric that stretches in one or two directions. Due to its low elasticity and limitations, it is a low-priced product and is generally designed as a split style swimsuit, which is not suitable for one-piece swimsuits.

The swimsuit fabric mainly made of 18% spandex is the best, as it has excellent elasticity and can stretch and contract freely with body movements.

In addition, there are swimsuits made of materials such as polyester fiber, chloroprene rubber, and nylon. Polyester fiber is usually lightweight, breathable, and has good stretchability, which can fit the body's curves well without restricting movement. Neoprene material swimsuits are relatively tight fitting, providing good support and protection, and have good durability and waterproofing. Nylon swimsuits have a soft texture, comfortable and lightweight feel, but they are easy to absorb water and have average breathability.
