Nylon or polyester, which one is better for swimsuits?

When choosing swimsuit fabrics, nylon and polyester each have their pros and cons, but polyester is generally better for swimsuits. Here are some comparisons:

Durability:

Polyester: Polyester has better chlorine resistance, so it can keep its color longer in pool water and is more resistant to chemicals in the water.

Nylon: Although nylon is durable, it is less durable than polyester in chlorine water and is more prone to fading and damage.

Breathability and comfort:

Nylon: Nylon has better breathability and is more comfortable, making it suitable for long-term wear.

Polyester: Polyester is relatively less breathable than nylon, but it dries faster after getting wet, making it more suitable for water activities.

Stretchability and elasticity:

Nylon: Nylon fabrics are generally more stretchy, fit comfortably, and are not easy to deform.

Polyester: Polyester is slightly less elastic, but it can still maintain a certain stretch, making it suitable for making fitted swimsuits.

UV resistance:

Polyester: Polyester is more UV-resistant and suitable for outdoor activities, especially when exposed to the sun while swimming.

Nylon: Nylon has poor UV resistance and is easily damaged by long-term exposure to the sun.

Polyester is a more suitable fabric for swimsuits, especially in swimming pool water environments, because of its good chlorine resistance and durability. Nylon is suitable for occasions with higher requirements for comfort and breathability, but it should be noted that it has poor chlorine resistance. Many modern swimsuits will mix these two materials to balance the advantages of both.
