As is well known, lycra, nylon, and polyester are currently the most commonly used materials in the swimwear category. Any special material such as wisps and twigs cannot be separated from the above three types of elastic characteristics. Many new swimsuits come with special treatments such as UV resistance, chlorine resistance, or splashing treatment. Lycra is a type of artificial elastic fiber with the best elasticity, which can extend to 4-6 times the original length and has excellent stretching. It is suitable for blending with various fibers and can enhance the advantages of texture sagging and wrinkle resistance. DuPont Lycra, which contains chlorine resistant ingredients, will give swimsuits a longer lifespan than regular swimsuits. Although the texture of nylon fabric is not as solid as that of Lycra fabric, its elasticity and softness are already on par with Lycra fabric. Currently, it is the most commonly used fabric for swimwear and is suitable for mid priced products. Polyester fabric is an elastic fabric that stretches in one direction and two directions. Due to limited elasticity, it is mostly used in swimming trunks or women's split halves, and is not suitable for jumpsuits. Fabrics that can be partially cut or applied with low unit price strategies.

The design of swimsuits is based on the principles of "comfort" and "fit". So most of the lining materials use nylon, which needs to be consistent with the elasticity of the fabric to not affect the comfort of consumers. Therefore, when choosing to use excipients, "elasticity" is an absolutely necessary requirement. In response to the trend of fashion, when using non elastic accessories such as metal, acrylic, and shells, it is necessary to choose a position in the design that does not affect the elasticity of the clothing body. When applied properly, the excipients will have an excellent finishing touch effect. When choosing swimsuit fabrics, it is best to choose elastic fabrics with a spandex content of more than 15%, so that the swimsuit can freely expand and contract with body movements; When swimming in a swimming pool, it is important to pay attention to the adaptability of the fabric to the chlorine molecular content of the water in the pool. Currently, swimwear made of the most popular three-dimensional elastic fabric in the world is most suitable for use in low-temperature water or swimming. Because this fabric has a lot of hollow space, it is easy to maintain body temperature. Try to buy as little or no imitation so-called "imported spandex high elastic fabric" as possible. One is that the spandex content of clothing fabrics is generally around 15-20%, and the other is that imitated fabrics have poor elasticity after being washed into water due to variations in composition.
