What's in Sunscreen and Why It Matters

First off, we need to understand what sunscreen is made of. Most sunscreens contain a mix of chemicals that work to protect our skin from the sun's harmful UV rays. These can include organic filters like oxybenzone, avobenzone, and octinoxate, as well as inorganic ones like zinc oxide and titanium dioxide.

The organic filters are great at absorbing UV rays, but they can also be a bit tricky when it comes to swimwear fabric. They're often dissolved in solvents or oils, which can interact with the fibers in the fabric. Inorganic filters, on the other hand, are more like tiny particles that sit on the surface of the skin and reflect UV rays away. They're generally less likely to cause problems for the fabric, but they can still leave a white residue, which might not look so great on your swimwear.

How Different Swimwear Fabrics React

Now, let's talk about the different types of swimwear fabrics and how they handle sunscreen.

Polyester Blend Fabrics

Polyester is a popular choice for swimwear because it's durable, quick - drying, and retains its shape well. When it comes to sunscreen, polyester blend fabrics usually do a pretty good job. The synthetic nature of polyester makes it less likely to absorb the chemicals in sunscreen. However, if you're using a sunscreen with a high concentration of oils or solvents, you might notice a bit of a build - up over time. This can make the fabric look dull and feel a little sticky.

To keep your polyester blend swimwear looking its best, it's a good idea to rinse it thoroughly with fresh water after each use. This will help remove any sunscreen residue before it has a chance to set in. You can also use a mild detergent specifically designed for swimwear to give it a deeper clean every once in a while.

Nylon Blend Fabrics

Nylon is another common fabric in swimwear. It's soft, stretchy, and has a nice feel against the skin. But nylon is a bit more porous than polyester, which means it can absorb sunscreen more easily. When sunscreen gets absorbed into nylon, it can cause the fabric to lose its color and elasticity over time.

If you have a nylon blend swimsuit, be extra careful when applying sunscreen. Try to avoid getting it directly on the fabric as much as possible. And just like with polyester, rinse it well after swimming to prevent sunscreen from building up.

Our Sustainable Swimwear Fabric

We also offer Sustainable Swimwear Fabric, which is made from eco - friendly materials. These fabrics are designed to be both kind to the environment and resistant to the effects of sunscreen.

The sustainable materials we use are often treated to be more hydrophobic, which means they repel water and sunscreen better. This helps to keep the fabric in top condition, even after repeated exposure to sunscreen and water. So, if you're looking for a more environmentally friendly option that can handle sunscreen well, our sustainable swimwear fabric is a great choice.

Chlorine Resistant Swimwear Fabric

In addition to sunscreen, chlorine in swimming pools can also be tough on swimwear. That's why we offer Chlorine Resistant Swimwear Fabric. This fabric is specially formulated to withstand the harsh chemicals in chlorine - treated water.

When it comes to sunscreen, our chlorine - resistant fabric has an added advantage. The treatment that makes it resistant to chlorine also helps to protect it from the chemicals in sunscreen. This means your swimsuit will last longer, even if you're using a lot of sunscreen and spending a lot of time in the pool.

Ribbed Swimwear Fabric

Our Ribbed Swimwear Fabric is not only stylish but also has unique properties when it comes to sunscreen. The ribbed texture can help to prevent sunscreen from pooling on the surface of the fabric. Instead, the sunscreen is more evenly distributed, which reduces the chances of it causing damage to the fabric.

However, because the ribbed fabric has more surface area, it's still important to rinse it well after use. And if you notice any sunscreen residue, you can gently rub the fabric between your hands to help remove it.

Tips to Protect Your Swimwear from Sunscreen

Here are some tips to keep your swimwear in good shape when using sunscreen:

  • Apply sunscreen before putting on your swimwear: This will reduce the amount of sunscreen that comes into contact with the fabric.
  • Wear a rash guard or cover - up: If you're going to be applying a lot of sunscreen, consider wearing a rash guard or a cover - up over your swimwear. This will create a barrier between the sunscreen and the fabric.
  • Rinse immediately: As soon as you're done swimming, rinse your swimwear with fresh water. This will help to remove any sunscreen and chlorine before they can cause damage.
  • Don't wring or twist: When drying your swimwear, gently squeeze out the excess water. Avoid wringing or twisting it, as this can damage the fabric.
