How to Choose the Right Waterproof material for swimsuit

In the scorching summer, swimsuits have become an indispensable part of our lives. Swimming is not only a way to exercise but also a leisure activity to relax. However, choosing the right swimsuit is equally important, especially when it comes to waterproof fabrics, as they directly affect the comfort, durability, and functionality of the swimsuit. The following article will discuss how to select the appropriate waterproof fabric for swimsuits, helping you to fully enjoy the fun in the water at the pool or on the beach.

Waterproof fabrics are typically woven from polyester or nylon fibers, both of which are synthetic fibers with excellent water resistance. These fabrics make swimsuits lightweight, allowing the wearer to move flexibly. The waterproof effect mainly depends on the density of the fabric fibers. In addition, high-quality swimsuit fabrics should be quick-drying and well-ventilated, as the wearer may spend a long time in the water, and excessive moisture absorption can cause discomfort. They also need to adapt to the environment of seawater and pool water, and have the ability to resist the sun. Currently, there are several fabrics with these characteristics, each with different compositions and ratios of fabric fibers, resulting in similar but different properties.

5 most popular waterproof fabrics for swimwear

Lycra

This fabric is composed of various synthetic fibers, among which the most famous is spandex. Lycra fabric is known for its excellent elasticity, capable of stretching to 6 to 7 times its original size, making it very suitable for making swimsuits that require continuous movement. Its texture is smooth, it does not easily deform, dries quickly, and is lightweight. In addition, there is a fabric called spandex-lycra, which is a blend of 90% spandex and 10% Lycra fibers. Spandex-lycra also has high elasticity and features a smooth and shiny fabric characteristic.

ITY (Interlock Twist Yarn) Fabric

This material is a blend of 95% polyester and 5% spandex (Lycra), and it has the following characteristics: waterproof function, extremely high elasticity, shape retention, cool touch, quick-drying, and a variety of color options.

Power Mesh Compression Fabric

This fabric is woven from 15% spandex and 85% nylon fibers, and with its synthetic fiber composition, it has excellent waterproof properties. Its mesh structure is sturdy, providing high elasticity in all directions. Additionally, the fabric is lightweight, quick-drying, and has a soft, smooth texture that is gentle on the skin.

Cristan Fabric

The fabric is woven from polyester and Lycra fibers, creating a dense weave with high elasticity and durability, similar to Lycra fabric. Its texture is soft and smooth, providing a comfortable experience for the wearer.

Nylon Fabric

Nylon fabric is known for its water-resistant properties and durability, maintaining its original shape. It is resistant to chemicals and sunlight, does not shrink easily, dries quickly, and its colors are less likely to fade. It is lightweight and comfortable, with a soft and smooth texture that provides a pleasant wearing experience for the wearer.

In addition to these five fabrics, the swimwear industry is also increasingly focusing on eco-friendly fabrics. Most swimsuit fabrics are made from synthetic fibers such as nylon and polyester, which can cause microplastic pollution during the washing process. Therefore, environmentally friendly synthetic fibers made from recycled plastics like fishing nets and plastic bottles, such as Econyl and Repreve, are gaining attention. Econyl is made from nylon fibers, while Repreve is made from polyester fibers. These eco-friendly fibers have low water absorption and provide excellent characteristics such as UV protection, chlorine resistance, tear resistance, and skin friendliness.

Understanding the types and characteristics of fabrics can help swimwear business owners choose the most suitable fabrics for their brand, ensuring product quality and standards. At the same time, purchasing fabrics from reputable suppliers can enhance the flexibility and growth potential of the business. For instance, suppliers should have ample inventory to support swimwear production and provide fabrics that meet reliable standards, such as OEKO-TEX® STANDARD 100, which certifies that these fabrics have been tested for harmful substances and are produced in environmentally friendly facilities. Furthermore, the AATCC Performance Testing Protocols (PTPs) standard also ensures the fabric's colorfastness, shape retention, fiber analysis, and water resistance.
