What Is Elastane: Elastane vs Spandex vs Lycra

If you’ve ever worn an item with stretch factor in the fabric, chances are that you’ve worn elastane. But what is elastane and how does it differ from other stretch materials like spandex and lycra?

And is elastane toxic to wear or perhaps sustainable?

That’s what this article is about!

What Is Elastane?

Elastane is a synthetic fiber invented in 1957, made from polyurethane and is known for its high elasticity. It is often used in sportswear and other garments where a closer fit is desired.

While elastane is very stretchy, it can also be quite strong, making it a popular choice for swimwear and other garments that need to withstand a lot of wear and tear. Elastane is typically made from polyurethane or polyester, though it can also be made from other materials.

Elastane is often used in combination with other fabrics to create a more comfortable and durable garment.

Elastane vs Spandex vs Lycra

You may think that elastane is different to both spandex and lycra as a stretchy synthetic fiber, but the truth is that they differ only in name!

Let me explain.

1. Elastane is the material.
2. Spandex is a brand which makes elastane.
3. Lycra is another brand which makes elastane.

So, if anyone tries to tell you that elastane is more durable than spandex or lycra, they’re lying! Because all three are one and the same!

To be fair, some of the confusion comes down to geographical location.

In the UK, the label in my jeans with stretch factor states that they contain elastane, while previous items I purchased when living in New York clearly state on their labels that they contain spandex.

You can see why people get confused!

Elastane Properties

Elastane has several positive properties which make it popular for garment sewing:

• Strength
• Elasticity
• Lightweight
• Durable

However, it also has some negative aspects:

• It is easily damaged by heat
• It is tricky to sew with a straight stitch machine as the stitch will need to stretch with the fabric
• Sewing across the stretch instead of with it means that the fabric may pucker

Is Elastane Toxic?

This is a question I have been asked on several occasions, and the answer is no – elastane is not toxic.

However, like all synthetic materials, it should not be ingested and should be kept away from flames.

Is Elastane Sustainable?

Again, the answer is no – elastane is not a sustainable material.

This is because it is made from petrochemicals, which are non-renewable resources.

In addition, when elastane is used, it is often blended with other fibers like cotton, as seen in all the super skinny jeans from the 90s and 00s. Sadly, this means that the fabric created will actually take a lot longer to decompose.

Is Elastane Comfortable?

One of the main reasons for elastane’s popularity is just how comfortable it is.

Because of its stretchability, any fabric with elastane will fit closer to the body and feel a bit like a second skin.

However, I should note that when the elastane becomes damaged – usually with exposure to heat via the dryer – it can distort and stretch out, making the garment it is used in a little saggy and unkempt in places.

How To Care For Clothing With Elastane

If you have clothing which is made with elastane, then you are safe to either machine wash or dry clean those garments.

However, I personally advise against drying them in the dryer. While some will say that tumble drying on a low heat setting is ok, I have done this once with the jeans I am wearing in the above photo and the elastane becomes damaged, which makes stretch recovery of the fabric very limited.

If elastane has been used in finer fabrics for underwear, you’ll be better off hand washing rather than machine washing, and allowing the garments to hang dry naturally.

What Is Elastane Used For?

Fabrics with elastane are commonly used for:

• Activewear
• Dresses
• Jeans / pants
• Swimwear
• Tops
• Underwear

Wherever there is a need for some stretch factor, fabric containing elastane is often used.

Final Thoughts On Elastane

So there you have it! Elastane is a synthetic fiber that is known for its high elasticity and strength, making it a popular additive to fabrics used for close fitting garments. While it isn’t toxic to wear, anyone with skin sensitivities to petroleum products should consider avoiding it.
