The best swimsuit fabric is mainly made of 18% spandex, and do not purchase swimsuits containing a large amount of polyester fabric, especially jumpsuits. The elasticity of the fabric is very high, otherwise it will be cramped during swimming.

1. Spandex fabric

The best material for swimsuits now is spandex, with a minimum spandex content of 15% and 18% being optimal. This type of swimsuit has excellent elasticity and can stretch and contract freely with body movements. When swimming, attention should be paid to the adaptability of the fabric to the chlorine molecular content of the water in the swimming pool. Currently, swimsuits made of the most popular three-dimensional elastic fabric internationally are most suitable for use in low-temperature water or swimming. Because this fabric has more hollow spaces, it is easy to maintain body temperature.

2. Nylon fabric

Nylon fabric is the material used in most mid range swimwear, which is a fabric obtained by blending or interweaving nylon filament or short fibers, combining the characteristics and strengths of each fiber. The characteristics of nylon fabric are toughness and durability, but the disadvantages are poor elasticity, easy wrinkling, decreased wet strength, and easy sagging when worn. Nylon swimsuits belong to the mid price range. Of course, compared to spandex swimsuits, the elasticity is not enough, but the toughness is very good. Due to its low price, it is also the most commonly used swimsuit fabric nowadays.

3. Polyester fabric

Swimsuits made of polyester fabric have less elasticity and are prone to limitations on the limbs, so they are mostly used on small split swimsuits and are not suitable for one-piece swimsuits. They are basically low-end products. This material is rarely used alone, and is mostly mixed with spandex and nylon for use.
