Before we start the article on how to shirk polyester fabric, we should first know, does polyester shrink? The simple answer is yes. Polyester shrinks when exposed to heat or moisture. Polyester fabrics are made from synthetic fibers, which shrink when exposed to water.
Washing and drying fabric can lead to its shrinking although in a small way. Where polyester is synthetic and does not undergo too much shrinkage unless it is blended with other natural fibers such as cotton.
3 Easy Methods to Shrink Polyester Fabric Made Clothes at Home
Polyester is made from durable materials that are resistant to shrinkage meaning that you can use it in a dryer.
If you want to shrink your polyester cloths, there is a choice of using a washing machine and a dryer for a small reduction in shrinkage; however, using an iron gives a significant shrinkage. You may also consider the shrinking process of polyester by using boiling water.
Let’s discuss all of the 3 methods in detail to know how you can do it yourself at home.
1. Using Washing and Drying
Repeated washing should not happen too often. It will cause the garment to lose its color, newness, and durability. You need to do it very carefully. Let’s start:
Turn the garment inside out
After checking your cloth’s pocket to make sure it’s empty. When ready to start the shrinking process, turn the garment inside out to help protect the colors and quality of the fabric.
You need to ensure the hot water, pressure, and all others therapy is applied to the out site (inner part) of your cloth. Bring all your garments and isolate them to make sure you wash identical colors and materials to minimize fading.
Wash the garment in hot water
Wash the garment in hot water by setting the washing machine to the hottest level and a long wash cycle. Use both the hot wash and rinse to capitalize on hot water’s ability to shrink polyester faster than cold water.
You only need to add detergents into the washing machine the same way you would wash the garment. Detergents will not interfere with the shrinking process.
It’s Time to use the dryer
Take the garment to the dryer as soon as possible after washing. Use the hottest dryer setting and take the longest drying cycle. Shrinking takes place faster due to the extreme heat coming from the dryer.
Check shrinkage levels
Confirm the shrinkage levels by pulling the garment out of the dryer and leaving it to cool at room temperature. You can take it back to the dryer if you need to reduce the polyester size.
When doing repeated washings, please note that color fades with every wash, therefore, try washing it several if you are not getting the required size. Iron is an alternative that can help reduce polyester further.
Pros and Cons of this Method
The advantage of this method is, that it’s easy to do compared to others methods. Where the machine is doing a much harder part for you.
The disadvantage of this method is, that if you repeat the process again and again, this will cause the clothing to lose its color and newness.
2. Shrink Polyester Cloths Using an Iron
For safety reasons using a hot iron over a damp polyester is not a recommended option.
The amount of heat produced by electric irons can cause damage to polyester, even sometimes melting it.
Let’s start the process:
Wash the garment in hot water
Like the washing and dryer use process in this ironing method, you need to wash the garment in hot water, set the machine to its highest and hot levels, and make sure the washing cycle is set to long. The wash setting and rinsing should be set to hot.
Before starting, washing makes sure your polyester cloth’s pocket is empty and it’s ready to go for a wash.
Place the cloth on an ironing board
Place the cloth on an ironing board and once the washing cycle is over, pull the polyester from the washing machine and move it to an ironing board. Make sure that the cloth is turned inside out to reduce the chance of fading.
Prevent the damage by laying a pressing cloth over the polyester cloth
Lay a pressing cloth over the garment and ensure it completely covers the garment to prevent damaging your clothing.
Use the Iron and follow the settings
Use a low or medium heat setting to prevent the polyester from becoming too stiff, pass the iron over the clothing, and keep on ironing until it is completely dry.
Do not set the iron to use steam because you need the dry iron to dry out the polyester, which is the exact effect you are looking for.
Pros and Cons of Ironing to Shrink
The pros are, as you need to do it manually, so you can set your iron heat level and adjust it as you iron your clothes. You can also monitor the progress on the cloth ironing and see if you are shrinking it just right.
Examine the Effects on the Fabric: Carefully examine the finished garment but make sure not to repeat the ironing process because it could damage and lead to fading of colors. By the time you reach this stage, you may have done more than one drying cycle as well as ironing and the chances are that you may have shrunk the polyester as much as you can.
3. How To Shrink Polyester by Using Boiling Water
Make sure your garment and boil water are ready
To make sure your cloth is ready follow these things:
- Check your cloth’s pocket (if any)
- Turn the cloth inner side out to exposé more to heat
- Boil water is ready in a pot
- The heat should remain between 68 to 81 degrees Celsius
Put your cloth into the boiling water pot
To realize a noticeable change in the polyester, take it when wet and dip it in boiling water. The boiling water breaks down the fibers leading to shrinkage.
More shrinking is possible when polyester and natural fibers blend with polyester.
Maintain the boiling time (30 to 60 minutes)
The right boiling point varies depending on the clothing size and fabric thickness; however in normal circumstances boil the clothes for about an hour, which is approximately the length of time a washing machine takes in the washing shrinking cycle.
Finish the process by cooling the water
To finish the process you need to cool the water by stopping boiling it. After boiling you can go for iron and after that check what is the results of your hard work.
If you think you need to shrink the polyester garment more you can repeat any process again.
Advantages and Disadvantages of Using Boiling Water Method
The only advantage of this process is you can check means to estimate the shrinkage percentage where is process is fully manual. Hot and cool water is in your hand end of the day.
The downside of this boiling water shrinkage of polyester cloths is you need to do it manually as you can see, already discussed. So it’s hard work and a time-consuming task as well.
And it is difficult to maintain the temperature. There is no fixed temperature for boiling water in this method. So your cloth may damage over hot water. Also, there is a risk of boil water control in a pot issue. I hope you can understand that.

Polyester is wrinkle-resistant that is why as soon as you are done washing there is no need to iron. High temperatures on the iron box will ruin the polyester by setting melt spots on your fabric.
