Polyester fabrics for swimwear against moisture and UV: performance analysis and buying guide

Polyester fabrics have become a popular choice for swimwear and beachwear due to their unique performance characteristics. They perform well in humid, sunny environments, resisting moisture and effectively protecting against UV rays. So, what are the advantages of this fabric? How to choose the right polyester swimwear for you?

Five core properties of polyester fabrics
Excellent moisture resistance
Polyester fibers' hydrophobicity allows them to quickly wick away moisture, keeping swimwear dry, thereby improving comfort and avoiding stickiness.

Excellent UV resistance
High-quality polyester fabrics are often specially treated to provide UPF (ultraviolet protection factor) to protect the skin from UV damage.

Strong durability
Polyester fibers' molecular structure gives them excellent resistance to stretch and abrasion, making them ideal for high-intensity water sports.

Color durability
Polyester fabrics have strong adsorption of dyes and excellent resistance to fading, and they still retain their bright colors even after long periods of exposure to the sun or soaking in chlorine water.

Lightweight and stretchy
Polyester is light and breathable, while also offering some stretch, which allows for more freedom of movement and activity.

A useful guide to choosing polyester swimwear
Check the UPF rating
Swimwear with UPF50+ blocks 98% of UV rays, making it a great choice for outdoor beach activities.

Pay attention to fabric thickness
Thinner polyester fabrics are better suited to the pool, while thicker ones are better suited to the sun at the beach.

Pay attention to blending ratios
Some swimwear blends polyester with spandex to improve stretch and fit. Choose swimwear with 10%-20% spandex to strike a balance between comfort and durability.

Check the waterproofing treatment
Some polyester fabrics have a waterproof coating that further improves water repellency and reduces the weight of the swimwear after it absorbs water in the water.

Choose sustainable brands
Recycled polyester fabrics are an environmentally friendly choice, while having the same excellent performance as regular polyester, making a contribution to the environmental cause.
