Choose Swimsuit Fabric: Polyester vs Nylon

One of the most important thing about swimwear, is to choose swimsuit fabric that really meets your demands.

In other words: It’s useless when you aim at producing long lasting competitive swimwear but using nylon swimsuit fabric.

But why is that? Let’s find out!

Polyester and Nylon blends are the two major swimsuit fabrics that dominate the female swimsuit industry.

Polyester and Nylon are non-elastic fibers, which share many of the same properties, such as durability, easy care, wrinkle and shrink resistance.

With adding an amount of Elastane both fabric will become stretchable. Elastane is also called spandex or Lycra (a brand name of spandex owned by Invista).

Choose swimsuit fabic with 2-way stretch

Swimsuit fabrics are either 1-way or 2-way stretch, also called 2- way or 4-way stretch. 1-way stretch fabric stretches in one direction while 2-way stretches in both directions, crosswise and lengthwise.

For a better fit on the body you should choose swimsuit fabric with 2-way stretch.

Choose Swimsuit Fabric With The Right Composition And Weight

An important property of swimsuit fabric is its composition and weight. As mentioned before Polyester and Nylon swimsuit fabrics are blended with Elastane. If you choose Nylon blends for your swimwear you have to check the spandex-to-nylon ratio. Choose swimsuit fabric with at least 80% of nylon.

If you are going for polyester there are two types of polyester fabric for swimwear. One is the composition of polyester and spandex, that should also have at least 80% Polyester, the other one is PBT 100% polyester. PBT is texturized polyester with natural stretch similar to spandex.

Choose swimsuit fabrics that weigh between 170 g/m2 – 200 g/m2. Personally, I always choose swimsuit fabric that weighs 190 g/m2, because it just feels so comfy and really soft to the body, not too light to show through and not too heavy.

Choose Swimsuit Fabric That Meets Your Demands

Polyester is the leading fabric among competitive swimwear because it is unlike Nylon chlorine and UV resistant and holds its color which Nylon can’t offer. Polyester is also faster drying and easier to dye.

But when it comes to absorbency, nylon is clearly one step ahead. It performs better in critical condition. It is smoother and softer and has a greater stretch ability than Polyester. Even though, it sits tight and lightweight to the body, Nylon gives a better movement capability than Polyester.

Did You Know That Polyester And Nylon Are Basically Plastics?

Oh Yes, That’s 100% true! You can google it, if you don’t believe me.

The everyday name of Polyester depends on whether it is being used as a fiber or as a material for making things like bottles for soft drinks.

When it is being used as a fiber to make clothes and swimsuits, it is often just called polyester. When it is being used to make bottles, for example, it is usually called PET.

Nylon Fabric for clothing and similar things is made from fibers of nylon, which are effectively strands of plastic yarn.

Both, Polyester and Nylon are synthetic manmade polymers by reacting together two different molecules. It requires a high volume of pressure and heat for the chemical reaction (plastic polymer) to occur. The liquid will then be pushed through holes also called a spinneret to form the fibers.

Since Polyester and Nylon are based on plastics, they are both recyclable without causing further damage to the environment. While recyclable Polyester is regenerated from plastic bottles, is recyclable Nylon made from fishing nets and carpets.

While Repreve and Seaqual only supply recycled polyester fabric, Carvico and Vivifytextiles supply both. However they are all really worth to check out!

Swimsuit Fabric Carvico Vita: Recyclable and Ultra Chlorine resistant

Carvico Vita Swimsuit fabic is what they call a techno-fabric. Techno-fabrics are fabrics that incorporate new technologies and new functionality into a traditional textile material in our case Polyester and Nylon. For example: As we know now, conventional Nylon blends are not Chlorine resistant but thanks to new technology it can be made though.

Since I purchased Carvico vita for the first time, I honestly can’t buy any other swimsuit fabric. They are completely from different worlds. I really love it!
