Does 100 Percent Polyester Shrink

Last Updated on 10 months by Susan Mayrich


Our clothing is one thing that we are never hesitant to spend money on. This is because it needs to give us more than just comfort and protection from the harsh environment. Good quality clothing has to look attractive, otherwise, we would not be spending so much on them. Clothing made of polyester proves to be one of the most affordable clothing materials, but you need to take care of this kind of clothes in order for them to remain in top shape. But does 100 percent polyester shrink? 

Polyester fabric resists shrinkage; however, it can shrink if washed with hot water, which is over 60 degrees Celsius. Drying polyester at higher temperatures also causes the fabric to shrink. Ironing with excessive heat can also cause polyester to shrink.

Are you curious if 100% polyester shrinks? Read this article to learn about why 100% polyester can shrink and how much does it shrink.

Are 100% Polyester Clothes Good?

Polyester is a synthetic fabric that is often made into clothing. It is durable and strong, making it resistant to wrinkles, shrinking, abrasion, and mildew. It is quick-drying and easily washable, making it ideal for activewear. Polyester is low maintenance and has a long lifespan.

It can be mixed with cotton or other natural fabrics to produce lightweight blends that are colorfast and less likely to shrink than 100% cotton.

If you hate ironing and your wardrobe consists mostly of casual clothes, you might find that polyester suits you very well.

Does 100 Percent Polyester Shrink


Is it not easy for 100% polyester to shrink. It is a fabricated fiber, which is made from petroleum products. In the process of making fabric from polyester, the fabric is stretched to adjust its length, which makes it resistant to shrinking or stretching.

Polyester is a man-made fabric made with polymer. Polymer is a long chain of molecules formed by joining together many monomers and it has unique characteristics such as resistance to shrinking and stretching. The polymer chains are held together with chemical bonds that make the fabric stretchable to certain limits and hence resistant to shrinkage.

The reason why 100% polyester does not shrink is that the fibers are stretchable and they can be stretched out to change their shape or size in any direction i.e., horizontally or vertically but they will return to their original shape when you release them and this property is called elasticity.

However, this does not mean that 100% polyester cannot shrink because it can shrink if you wash it with hot water or dry it at very high temperatures. If you want your 100% polyester fabrics not to shrink then wash them in cold water and iron them at low temperatures only because high heat can cause shrinkage even though it resists shrinking by nature.

Does 95 Polyester 5 Spandex Shrink

The elastic in spandex reacts to heat, and that can mean shrinkage when you wash the garment. The more spandex a garment contains, the more likely it is to shrink in the wash. This is especially true if you’re using hot water or putting it in the dryer. Some shrinkage is normal and expected, but there are steps you can take to limit how much it happens.

The main factor in how much a garment will shrink is what type of fibers it contains. The polyester in the polyester-spandex fabric is a plastic-like material that was developed as an alternative to silk. It is more heat resistant than spandex, so it won’t shrink as easily in the wash as a pure spandex garment. The amount of polyester will help reduce spandex shrinkage when you blend the two, but it won’t prevent it entirely.

Can You Put 100 Polyester in the Washer?

Yes, 100% Polyester can be washed in the washing machine. It doesn’t need too much attention and you don’t have to worry about it shrinking. But, it does need some extra care to make sure it doesn’t shrink or fade.

The most important thing to keep in mind when washing a polyester is to wah it warm or cold water. Hot water can cause it to shrink and damage your clothes.

Can You Put 100 Polyester in the Dryer?

You can dry 100 percent polyester in the dryer on low heat. While polyester is not as delicate as some fibers, it’s best to avoid drying it at high temperatures. 

You should check your garment’s care label first. If your garment has a low heat setting, use that instead. If it doesn’t have any specific instructions for drying temperatures, then it is safe to put the garment in the dryer on low heat.

Does Polyester Shrink After Washing

Polyester is one of those fabrics that is not very easy to shrink. But if you have a polyester item, you might have noticed it getting smaller after washing or drying. Polyester is a man-made fabric that is made with polymer. It is resistant to wrinkle and shrink. But if you wash polyester with hot water, it can cause shrinkage. A polyester garment can stretch over time, but it will not shrink back to its original size easily after stretching.

How Much Does 100% Polyester Shrink

A garment made of 100 percent polyester will show up to 5% or no shrinkage because the fabric is made of synthetic fibers. The fibers are resistant to shrinking because they are created with bonds that do not break when heated. Even if you wash and dry a polyester garment at home using hot water and high heat, it will only shrink a small percentage, usually 1 to 5 percent.

Can You Shrink 100% Polyester?

Yes, you can shrink 100% Polyester, but it must be done carefully.

While 100% polyester is naturally heat-resistant, exposing the fabric to high temperatures can damage its integrity. The best way to shrink 100% polyester is to wash it on a hot setting and then throw it in the dryer, preferably while wet.

At What Temperature Does 100% Polyester Shrink?

While the melting point of polyester is 500 degrees Fahrenheit, the fiber itself will begin to shrink well before that. At 140 degrees Fahrenheit, most types of polyester will shrink about 3 percent and will continue to shrink until about 180 degrees Fahrenheit.

Polyester is a type of plastic formed from long chains of a molecule called a polymer. The chains are formed by joining together small molecules called monomers (in this case, esters). At high temperatures, the polymer chains break down and can reform into shorter chains, which results in a shorter fiber. 

How to Shrink 100% Polyester

The thing is, polyester, a type of plastic, was created to resist shrinkage and wrinkles. This makes it a poor choice for shrinking on purpose. There are ways to shrink polyester in limited circumstances, but you have to take care not to damage it.

Soak the polyester in hot water for a while

Fill a bucket or sink with hot water. Place the polyester inside the bucket or sink and let it soak until it is totally submerged in the hot water. Let it soak for at least one hour. The longer it soaks, the more it will shrink.

Wash at hottest settings

When you wash, make sure to put them in the washer in the hottest setting possible. If there is only a warm setting available, choose that one instead of cold or cool. It has to be as hot as possible to have any effect on polyester fabric.

Hot drying

Dry the fabric using high heat. This will help shrink the fabric further and should make it noticeably smaller than before washing and drying it on high heat. If you’re feeling particularly bold, try doing this twice in a row to shrink it even more.

In hot Ironing

If there are specific areas that need more shrinking, iron them with a hot iron before drying in the dryer on high heat again. Iron polyester on the hottest setting possible. Use steam if you are able to or just press the item firmly with the iron until it is dry and smooth to touch.

Hang the garment

Hang polyester clothing near a radiator or other source of heat once it is dry, such as in front of a window on a sunny day or near an open fire, if you want to shrink it further.

Things to Know When Shrinking a Polyester

At this stage, you should be able to shrink your polyester. However, there are some key things that you need to keep in mind when shrinking your polyester.

It’s not advisable to directly expose the fabric to heat as it may get damaged. It’s better to use the warm water method together with heat from a dryer and ironing board.

Avoid stretching the fabric as you work on it especially after washing and drying. This is because the fabric might not return to its original size once stretched.

When working on a tightly woven polyester, it’s better if you use steam iron instead of hot iron so that you can protect the fabric from being damaged by heat.

How to Wash 100 Polyester

Polyester is a synthetic fiber that’s strong and durable. It resists wrinkles, shrinking, and mildew. It’s also colorfast, so it won’t fade if you wash it in hot water or put it in the clothes dryer.

Care for polyester by washing it with cool water on your machine’s gentle cycle. Use a mild detergent, and don’t use chlorine bleach. If the label recommends tumble drying, choose low heat. Many polyester garments can be ironed in a low-heat setting, too.

Wash polyester in warm water using your machine’s normal cycle.

If the garment is white or very light-colored, you can use chlorine bleach as long as the fabric is at least 65 percent polyester. Add 1/2 cup of bleach to the washer when washing whites. If you’re washing colors, use oxygen bleach instead of chlorine bleach to avoid fading them.

Use liquid detergent with all types of fabric softener rather than powder detergent because powder detergent can stick to the fibers and make it difficult for water to penetrate during rinsing cycles.

Avoid using too much detergent when washing polyester.

Line dry polyester clothing whenever possible to avoid shrinking.
