Does Spandex Shrink When Dried? A Comprehensive Guide

Spandex does shrink but don’t worry – with the right care, it can last you a very long time. Spandex, also known as lycra or elastane, is a synthetic fiber known for its stretchy and elastic properties. It’s commonly used in making stretchy and form-fitting clothing like leggings, swimsuits, and athletic wear. The key to making your Spandex last is proper care.

Improper care can shrink Spandex by 5-20%, depending on how well you care for it and the fabric blend. You can wash Spandex at temperatures up to 60°C (140°F) without deforming it. The primary cause of spandex shrinkage is exposure to heat and, to some extent, agitation. It’s crucial to avoid washing Spandex in hot water or spinning it too much with other fabrics. Washing Spandex tends to stretch if the water is heated, so always opt for a gentle cycle with cold water in the washer.

Consider using a protective mesh or fabric bag for your spandex garments to prevent agitation. This prevents them from tangling up with other fabrics and losing their shape. These steps ensure that your spandex fabric remains in good condition without stretching out of shape.

If you want your favorite spandex outfit to last a long time, avoid things that generate heat, like dryers, hot water washes, and irons. These can lead to shrinking, and we want to avoid that. Also, wearing your spandex items often is a good idea. This helps them maintain their shape over time.

In summary, this article covered Does Spandex Shrinks and provided tips on caring for your cherished pieces. To get more details on how and when to wash these items, continue reading below! Taking extra time to care for your Spandex can ensure it stays stretchy and comfortable for years.

What Is Spandex Made Of?

Let’s break down the nitty-gritty of Spandex, or as some call it, lycra or elastane. Spandex is not some magical fabric; it’s a man-made fiber created from a synthetic polymer called polyurethane. Polyurethane itself is a product of mixing a diisocyanate with a polyol.

Here’s the spandex birth story: First, they take that polyurethane and break it down into tiny beads or granules. Then, these little guys are melted and pushed through a spinneret, like a gadget with super small holes. As the melted polymer oozes out, it cools down and becomes a continuous filament – a long, skinny thread.

These filaments join forces and get twisted into a yarn, and voila! You’ve got spandex fabric. The cool thing about Spandex is that you can play with its weight, weave, and even mix it up with other fibers like cotton, silk, or wool. This combo gives you that comfy, stretchy feel without making your clothes too thick. Think leggings, swimwear, and tights – all snug and flexible.

In the United States, the spandex scene usually stars nylon and polyester, plus a special guest called modacrylic. Nylon-type Spandex is like a breathable, soft superhero, winning in the stretchy and durable department. On the other hand, polyester spandex is the more budget-friendly sidekick, though it might not always outshine nylon in the clothing game. Whether you’re rocking nylon or polyester spandex or maybe a modacrylic mix, you’ve got a bit of science working wonders in your clothes.

Does Spandex Shrink?

Does Spandex Shrink

You might be wondering, “Does spandex shrink?” Well, the answer is yes. While Spandex is great for stretching and adjusting to your body, it’s also sensitive to shrinking. The issue arises when you expose it to heat, agitation, or high-heat tumble drying.

Let’s talk about the heat problem. If you toss your Spandex into a hot dryer, the high temperature can break down the fibers, making it lose its original shape. Even washing it in hot water can cause it to stretch and then shrink when dried in a high-heat dryer. To keep your Spandex looking fresh and fitting just right, steer clear of high heat. Stick to cold water when washing, and avoid using a warm or hot dryer.

Let’s break down the three main culprits: Heat, Agitation, and Drying. High heat is a spandex shrinkage culprit, as we’ve discussed. Agitation, like rough washing, can also lead to shrinkage. Tumble-drying on high heat can spell trouble for your Spandex. To avoid these causes, wash your Spandex in cold water, handle it gently to prevent agitation, and opt for a low-heat dryer or, better yet, air dry it. These steps allow you to keep your Spandex looking good and fitting comfortably for the long haul.


Hey there! Let’s chat about keeping your spandex clothes in top-notch shape. As awesome as it is, Spandex has a quirk – it can shrink when things get too hot. When exposed to high temperatures, like in a dryer or hot water, those spandex fibers can contract, making your clothes 5-10% smaller on average. It happens because heat activates the bonds between the molecules in the fibers, making them huddle up, resulting in a tighter weave.

When washing your spandex gear, go for cold water to dodge the shrinkage bullet. And when it’s time to dry, opt for a low or medium heat setting. Say no to high temperatures, whether ironing or using hot water, because that’s a shrinkage invitation.

Remember to check the care instructions on your spandex clothes. Different types of Spandex might have different heat tolerances. Some may be cool with a low-heat machine dry, while others prefer the gentle touch of air-drying to stay shrink-free. Remember these tips; your spandex buddies will stay stretchy and comfy for the long haul!


When you wash Spandex, the agitation in the washing machine can make it shrink. That’s because all the moving around stresses the spandex fibers, making them shorter and more compact. Whether it’s in a washing machine or a basin of water, the wash cycle or manual agitation can cause this shrinkage.

To keep your spandex clothes from shrinking, go easy on them during washing and drying. Choose the gentle cycle, and handle your garments with care. Don’t wring or twist them, as that adds more stress and increases the risk of shrinkage. Also, pay attention to the care instructions on the label of your spandex clothes. Different types of Spandex might have different tolerance levels to all this movement and stress, so following the care guidelines is essential. Taking these steps ensures your spandex clothes stay stretchy and comfy for longer.


Let’s chat about Spandex and how it can play tricks on us in the drying process. You know, that stretchy, comfy fabric we all love? Well, it can be a bit picky when it comes to drying.

Spandex tends to shrink if it spends too much time in the dryer or faces high temperatures. When spandex garments hit the heat, whether from the dryer or just the air, the fibers in the Spandex get all active. They start huddling up and getting closer, making the whole fabric shorter and denser. And voila, shrinkage happens.

Grab your garments from the dryer while damp to dodge this spandex shrinkage. Let them finish up the drying process in the open air. Steer clear of high heat settings or marathon drying sessions, which can increase the shrinkage risk.

Remember to be the best buds with the care instructions on your spandex gear. Different spandex types can have different heat tolerances and might need specific drying methods. Some spandex pals might be cool with a low-heat machine dry, while others might demand the VIP treatment of air-drying to avoid the dreaded shrink.

Spandex is the superhero of stretchy fabrics, and most wardrobes are likely filled with it. If you’re hanging out in Spandex, watch the drying game. And if you notice some unexpected shrinkage, you’ll know where it came from. Happy stretching!

What Causes Spandex to Shrink?

The main causes are explained below:

Water Temperature

Watch out for high water temperatures when washing Spandex because they can shrink it. Handwashing your garment instead of tossing it in the dryer is good if you use warm water. Remember, if Spandex gets soaked in soapy water for too long, it might lose some stretchiness. Even when hand washing, try not to let it soak in warm water for an extended time. Taking care of your Spandex this way ensures it stays elastic and fits you just right. Next time you clean your spandex gear, give it a gentle hand wash and avoid that hot water for a happy, stretchy fabric!

Usage Of Dryer

Hey, be careful with your spandex clothes in the dryer! That heat can make them shrink. Take them out while they’re a bit damp, not bone-dry. Lay them flat on towels to air-dry – that’ll keep them from getting smaller. If you hang your pants on a hanger, they might curl up and shrink slightly. But if you lay them flat, the spandex fibers won’t pull together, and you’ll dodge the shrinkage. Remember, treat your Spandex right, and it’ll stay the perfect fit!


The soap you use in your laundry can mess with the stretchiness of your spandex outfits. Certain detergents have lots of alkalines, which can suck the life out of your clothes, making them less stretchy. Be a label detective! Read the care tags on your clothes and see what they’re made of before tossing them in the wash. It’s a small move that can keep your Spandex feeling springy and ready for action.


Washing Spandex is easy, and you’ve got options: do it by hand or in a washing machine—it’s up to you! The key is in how you go about it. If you choose the machine route, go for cool water and the gentle cycle. If handwashing is more your style, opt for warm or lukewarm water; it’s gentler than the machine’s agitation. But here’s the crucial part: never toss your Spandex into the dryer if you’ve used warm water during washing. Treat your Spandex carefully; it’ll stay stretchy and comfy for longer. Go ahead, choose your method, and keep your Spandex in top shape!

Hang Dry Or Flat Dry

When air-drying your spandex gear, ensure they have some breathing room. Don’t cram them together in a small space. This way, they can air out properly, staying soft and wrinkle-free. They might lose their stretchiness and become less comfy if they hang over each other. It’s ideal to lay them flat to dry for less shrinkage risk. Give your Spandex the space it needs; it’ll keep its stretch and feel good when you wear it.

Does Spandex Shrink In The Dryer? 

Does Spandex Shrink

Spandex can shrink in the dryer, especially if you expose it to high heat or don’t take proper care of it. Spandex is a synthetic fiber known for its incredible elasticity, allowing it to stretch significantly.

It’s not the best idea; it might send your Spandex into a shrinking frenzy. Stay clear of harsh detergents and fabric softeners – they can strip away the natural oils, making your Spandex stiff or causing it to shrink. Bleach is a big no-no unless you’re going for a tie-dye effect.

Once your Spandex has taken a bath, treat it with kindness. Tumble dry on low heat or let it air dry. Skip the high heat – it’s a shrinkage risk. Spandex threads are delicate, and vigorous spinning can lead to unwanted downsizing.

Most spandex sidekicks come with a tag that spills the beans on the ideal wash settings and how long they should mingle in the washing machine before you hit the stop button. Follow the tag’s advice, and your spandex squad will be ready for action whenever you need them!

How to Prevent Spandex from Shrinking?

Taking care of your spandex garments is crucial to prevent shrinkage. Let’s break down these steps in a friendly, detailed way so you can keep your Spandex looking great.

Step 1: Pre-Wash Check

Before diving into the washing process, give your Spandex a once-over. Look for dirt or stains and remove loose threads using scissors or a seam ripper. Spandex is elastic, so loose threads can lead to pilling over time. A little pre-wash attention goes a long way.

Step 2: Get the Temperature Right

Pay attention to the water temperature. Using hot water is a big no-no for Spandex. It can harm the fibers and make them more prone to shrinking. Opt for cool water instead. This not only prevents unwanted shrinkage but also helps with wrinkle control.

Step 3: Soak Smartly

Reduce spandex shrinkage by letting your garment soak in cool water with mild detergent. This gentle soaking prevents the spandex fibers from getting agitated, keeping them in top shape.

Step 4: Separate Your Spandex

To further prevent shrinkage, wash your Spandex separately from other clothes. If your laundry load includes spandex items, use a separate cycle in the washing machine or wash them by hand in a sink with mild detergent and no bleach. This individual attention ensures your Spandex gets the care it deserves.

Step 5: Be Cautious with Vinegar

Some folks use vinegar to preserve their Spandex but be cautious. While it can help, it might also cause lint or debris to stick to your clothes. Make sure your spandex garment is in good condition before trying this method.

Step 6: Don’t Overdry in the Dryer

A common mistake is leaving Spandex in the dryer until it’s bone dry. This can make it over-dried and stiff. Instead, take it out a bit early and let it air out. Hang it over a chair for about 10 minutes. This simple step prevents wrinkles and pilling, ensuring your garment maintains its shape when you wear it.

Remember, Spandex isn’t the only fabric that can shrink in the wash. Wool and cotton are culprits, too. Always check the washing instructions on the tag before tossing your garments into the wash. Knowing the right techniques can keep your clothes fitting perfectly and wash after wash.

Taking care of your Spandex is like giving it a little spa treatment. Follow these steps, and your Spandex will thank you by staying stretchy and fabulous!
