Swim Elastic vs Regular Elastic

The main difference between swim wear elastic and regular elastic is the ability to last longer in salt and chlorine. Swimwear elastic has been made to withstand salt, UV radiation and chlorine in pools while the regular elastic will fall apart very quickly when they are exposed to chlorine, salt and other chemicals.

Another thing that differentiates swimwear elastic from regular elastic is fibre. Swim Elastic is usually a combination of cotton and rubber unlike regular elastic. The rubber is stronger when exposed to salt, chlorine, UV radiation and other chemicals unlike other regular elastic.

let’s learn a bit about these different types of elastics.

Different Types of Elastics

Regular Elastic

Regular elastics are used for other purposes and pieces of clothings. They are usually of different types;

Braided Elastic

Braided elastic has lengthwise, parallel lines. They tend to narrow when they are stretched, they also roll easily unlike woven and knitted elastics. When sewn on, braided elastics tend to lose their stretch ability. They are better used in necklines, sleeves etc.

Knitted Elastics

Knitted elastics are gotten by knitting elastic fibres together. They are softer than woven and braided elastics therefore they do not lose their stretch when sewn on. They roll more easily than woven elastic but less than braided elastic. They can be used for waistbands and bra bands.

Woven Elastics

Woven elastics are also referred to as non roll elastic. They are very firm and do not roll unlike the other two types, they also retain their stretch ability when sewed on.

Clear Elastic

Clear elastic is used to gather knits and help garments to stay in place when worn. It is also used to keep bands in place due to the fact that it has more friction compared to other fabric elastic types.

Other types of elastics are;

Lingerie Elastic

This elastic is used in lingeries. It is very soft and usually made from lace. The finer finish is usually sewn to show on the lingerie.

Fold Over Elastic

This elastic is usually used for underwear, headbands and hair ties. It is meant to fold over the edge of a cloth for finishing.

Buttonhole Elastic

This is usually used for waistbands in pants or trousers. It has buttonholes that buttons are now fixed in, this helps to adjust the tightness of the trousers whenever it’s needed.

What Is The Difference Between Swim Elastic and Regular Elastic?

Now that we know the types of elastics we have and what they are meant for, let’s see their differences.

1. Purpose

Swim elastics are made especially for swimming while regular elastics are made for other purposes and garment projects.

2. Fibres

Swim elastics are made out of cotton and rubber elastic which are chlorine resistant while regular elastics are made from polyester and rubber. These fibres are suitable for most garments but not swimsuits. They are not chlorine resistant and will break down when exposed to chlorine, saltwater, UV radiation, sunscreen and even heat. The swim elastic on the other hand is specially made to be exposed to this type of situation.

3. Durability

Swim elastics last longer than regular elastic when used in swimsuits because they are chlorine resistant. They stay longer when exposed to UV radiation, chlorine, saltwater and other chemicals. Regular elastics, on the other hand, are not so firm, especially the braided elastics, they lose their elasticity quickly and when exposed to chlorine, saltwater and chemicals then they fall apart.

Is Clear Elastic Good for Swimwear?

Since we know that elastics like rubber elastic can be used in place of swim elastic especially because they are mostly chlorine resistant, then “is clear elastic good for swimwear?

Well, in this situation, it’s a yes and a no. I say yes because, you can use any elastic you want for your swimsuits, nobody will judge you for doing that. In fact, a lot of people like the feel of clear elastic on their bodies better than any other type of elastic.

However, it is a no because clear elastic is not as firm as other types of elastics in the first place, it will easily break down completely when exposed to heat, chlorine, UV radiation, sunscreen, saltwater and other minerals and chemicals in the water. In fact, it will not hold as long as you want at all.

But, if you will not be using your swimwear in places that will expose you to the conditions above then you can go right ahead and use it else please avoid using clear elastic. If you will use it at all, it should be very minimal.

Can You Use Regular Elastic for Swimsuit?

I know that, “can you use regular elastic for swimsuits” is another important question to ask when dealing with elastics.

Regular elastics can be used for swimwear. In fact, regular elastics like rubber elastic are known to be used as a substitute for swim elastic. Rubber elastic can be quite a challenge to work with because it can be quite slippery but it also gives great finishing touches when used.

When using regular elastic for your swimsuits, you should avoid using any polyester elastic because they are not made to be exposed to chlorine, saltwater, UV radiation, sunscreen, heat and other chemicals. It is only a matter of time before they fall apart and lose their elasticity.

Regular elastics like braided elastic can also be used for swimsuits but unlike swim elastic, they cannot withstand saltwater, chlorine and other chemicals, over time they lose their elasticity.
