Hey there! As a supplier of Polyester Swimwear Fabric, I've seen my fair share of swimwear out there. One question I often get asked is, "How can you tell if a swimwear is made of polyester fabric?" Well, I'm here to break it down for you in this blog post.
1. Look at the Label
The easiest way to find out if a swimwear is made of polyester is to check the label. Most swimwear manufacturers are required to list the fabric composition on the label. If you see "polyester" listed, then you know for sure that the swimsuit contains this material. Sometimes, it might be a blend, like "80% polyester, 20% spandex." Spandex is often added to polyester swimwear to give it stretch, which is super important for a good fit in the water.
But be careful! Sometimes the label might be hard to read, or it could be missing. In that case, you'll have to rely on other methods to figure out if it's polyester.
2. Check the Feel of the Fabric
Polyester has a distinct feel. It's usually smooth and slippery to the touch. When you run your fingers over a polyester swimwear, it glides easily. Unlike natural fabrics like cotton, which can feel soft and a bit fuzzy, polyester has a more synthetic and sleek texture.
If you pinch the fabric between your fingers, it should hold its shape well. Polyester is a durable fabric, so it won't wrinkle easily. You can give it a little tug, and it should stretch a bit if there's spandex in the blend, but it will quickly bounce back to its original shape.
3. Examine the Appearance
Polyester swimwear often has a shiny or lustrous appearance. It can look quite sleek and modern, which is why it's a popular choice for swimwear designers. The fabric also tends to have a uniform look, with no visible irregularities or bumps like you might see in some natural fabrics.
Another thing to look for is how the fabric drapes. Polyester has a good drape, meaning it hangs nicely and follows the curves of your body. It won't bunch up or look stiff in all the wrong places.
4. Consider the Color and Print
Polyester is great at holding color. Swimwear made of polyester will usually have vibrant, long - lasting colors. The prints on polyester swimwear also tend to be sharp and well - defined. If you see a swimsuit with really bright, bold colors and detailed prints that don't seem to be fading or bleeding, there's a good chance it's made of polyester.
Also, polyester is resistant to fading from the sun and chlorine in the pool. So, if you see a swimwear that still looks as good as new after a few seasons of swimming, polyester could be the culprit.
5. Do a Burn Test (with Caution!)
This is a more advanced method and should be done with extreme caution. Take a small, inconspicuous piece of the fabric (like a loose thread) and hold it with a pair of tweezers. Then, carefully bring a flame close to it.
Polyester burns with a yellow flame and melts into a hard, black bead. It also gives off a chemical smell, similar to burning plastic. However, this test should only be done if you're confident in your abilities and have a safe environment to do it in. You don't want to damage the swimwear or start a fire!

Why Choose Polyester for Swimwear?
There are several reasons why polyester is a top choice for swimwear. First of all, it's highly resistant to water. It dries quickly, which is essential when you're getting in and out of the pool or ocean. You don't want to be walking around in a wet, heavy swimsuit all day.
Polyester is also very durable. It can withstand the harsh chemicals in pool water, like chlorine, as well as the salt in seawater. This means your swimwear will last longer and keep its shape and color over time.


In addition, polyester is easy to care for. You can usually just throw it in the washing machine on a gentle cycle and it will come out looking good as new.
