1. The material of the swimsuit

Commonly used materials for swimsuits include DuPont Lycra, nylon, and polyester, with good waterproofing and elasticity.

DuPont Lycra: Artificial synthetic elastic fiber, with excellent elasticity that can be extended to 4-6 times its own. This fabric can be blended with various fibers to increase the drape and wrinkle resistance of the fabric. DuPont Lycra swimsuits with chlorine resistant ingredients have a longer lifespan.

Nylon: Compared to DuPont Lycra, it is not strong enough, but the fabric's softness and elasticity are similar, and the price is relatively cheap, making it the most commonly used fabric for swimsuits nowadays.

Polyester: also known as polyester fiber, this fabric has poor elasticity, so it is often used on split swimsuits and trunks and is not suitable for one piece swimsuits.

2. The difference between swimsuits and underwear

Swimwear: The materials of the swimsuit are mostly DuPont Lycra, nylon, polyester, etc., and the style is mostly tight, with good waterproof and elastic properties, which can reduce the burden on the body and reduce resistance during swimming.

Underwear: It belongs to daily clothing and is mostly made of pure cotton, with good skin affinity and breathability, and a lighter and thinner touch.
