How To Shrink 100 Polyester
Polyester is a synthetic fiber that is used in a wide variety of clothing and home goods. It is known for its durability, wrinkle resistance, and moisture wicking properties. However, polyester can also be difficult to shrink. If you have a polyester garment that is too large, there are a few methods you can try to shrink it.
One method is to wash the garment in hot water and then dry it on high heat. This will cause the fibers in the polyester to contract, which will shrink the garment. However, it is important to note that this method can also damage the garment, so it is important to test it on a small area first. Another method is to use a commercial fabric softener. Fabric softeners contain chemicals that can help to relax the fibers in the polyester, which will also cause the garment to shrink. However, it is important to follow the instructions on the fabric softener label carefully, as using too much fabric softener can damage the garment.
If you are not comfortable using either of these methods, you can take the garment to a professional cleaner. Professional cleaners have access to specialized equipment and chemicals that can safely shrink polyester garments. However, this method can be more expensive than doing it yourself. Ultimately, the best method for shrinking a polyester garment depends on the specific garment and the desired results. It is important to test any method on a small area first to ensure that it does not damage the garment.

Steam Shrinking Technique
Steam shrinking is a popular and effective way to shrink 100% polyester. Here’s a detailed step-by-step guide on how to do it:
Materials you’ll need:
| Item | Quantity |
|---|---|
| 100% polyester garment | 1 |
| Steamer | 1 |
| Ironing board or heat-resistant surface | 1 |
Step 1: Prepare your garment and work surface
Lay your 100% polyester garment flat on an ironing board or heat-resistant surface. Ensure the surface is clean and free of any wrinkles or debris that could transfer onto your garment.
Step 2: Heat your steamer
Fill your steamer with water and heat it according to the manufacturer’s instructions. Once it’s heated up, hold the steamer about 6-8 inches away from your garment.
Step 3: Start steaming your garment
Starting from one edge of your garment, slowly move the steamer back and forth across the fabric. Hold the steamer for a few seconds in areas you want to shrink more. Avoid holding it in one place for too long, as this can damage the fabric.
Step 4: Test the shrinkage
Periodically, stop steaming and allow your garment to cool down slightly. Gently pull on the fabric to check if it has shrunk to your desired size. If not, continue steaming until you’re satisfied with the results.
Step 5: Let your garment cool and dry completely
Once you’re finished steaming, hang your garment to dry completely at room temperature. Do not put it in the dryer, as this can further shrink or damage the fabric. Once it’s dry, it’s ready to wear or store as you wish.
Commercial Shrinking Methods
Commercial dry cleaners and tailoring services use specialized equipment and techniques to shrink polyester professionally. These methods offer precise control and consistent results, ensuring that your polyester garments fit perfectly.
6. Garment Steaming
Garment steaming is a gentle method that involves exposing the polyester garment to steam generated by a commercial steamer. The high heat and moisture help relax the fibers, causing them to shrink gradually. This technique is particularly suitable for delicate polyester fabrics that cannot withstand high temperatures or harsh chemicals.
To shrink polyester using garment steaming, follow these steps:
| Step | Description |
|---|---|
| 1 | Place the polyester garment on a hanger or mannequin. |
| 2 | Hold the steamer nozzle a few inches away from the garment. |
| 3 | Move the steamer nozzle up and down the garment in a steady motion, focusing on areas that need shrinking. |
| 4 | Allow the garment to cool completely before checking the results. |
Repeat the process if necessary to achieve the desired level of shrinkage.
Tips for Achieving the Desired Shrinkage
1. Determine Fabric Content
Ensure that the fabric is 100% polyester, as other fibers may not shrink effectively.
2. Prepare the Garment
Wash the garment in hot water using a regular detergent, rinse, and wring out excess water.
3. Set the Temperature
Use the hottest water temperature that the fabric can tolerate, typically indicated on the garment’s care label.
4. Agitate the Garment
Place the garment in the washer and agitate it vigorously for the recommended cycle.
5. Dry on High Heat
Transfer the garment to the dryer and set it to the highest heat setting that the fabric can withstand.
6. Repeat Until Desired Shrinkage
Repeat steps 2-5 until the garment has reached the desired level of shrinkage.
7. Measuring Shrinkage
To accurately measure shrinkage, place the garment on a flat surface and take measurements of its length and width before and after the shrinking process. Calculate the percentage of shrinkage using the following formula: 100 – ((New Measurement / Original Measurement) * 100).
8. Care and Maintenance
Once the desired shrinkage has been achieved, wash and dry the garment as usual to prevent further shrinkage or color fading.
| Shrinkage Percentage | Number of Washes |
|---|---|
| 10% | 2-3 |
| 20% | 4-5 |
| 30% | 6-7 |
Troubleshooting Common Issues
100% Polyester Did Not Shrink
The fabric was not heated to a high enough temperature or for a long enough duration. Alternatively, the particular type of polyester being employed may be inherently resistant to shrinkage.
Polyester Did Not Shrink Evenly
Inconsistent heating during the shrinkage process may cause uneven shrinkage. To remedy this, ensure uniform heat distribution by using a steamer or placing the fabric in the center of the dryer.
Polyester Lost Color or Became Brittle
Excessive heat or prolonged exposure to heat can damage polyester. To avoid this, use the lowest possible heat setting and monitor the shrinkage closely.
Polyester Melted
Extreme heat can cause polyester to melt. Always refer to the fabric care label for recommended heat settings and avoid overheating the fabric.
Polyester Developed Holes or Tears
Rough handling or excessive stretching during the shrinkage process can damage the fabric. Handle the fabric gently and avoid overstretching it.
Polyester Became Stretched Out
Improper drying can cause polyester to become stretched out. Always tumble dry on low heat or air dry to prevent stretching.
Polyester Is Wrinkled
Remove wrinkles from polyester by using a steamer or ironing the fabric on a low heat setting. Avoid ironing directly on the fabric and use a pressing cloth for added protection.
Polyester Is Still Too Large
If the desired shrinkage is not achieved, consider the following options:
| Shrinkage Method | Additional Notes |
|---|---|
| Boiling Water | Dip the fabric in boiling water for 1-2 minutes, then remove and immediately rinse in cold water. |
| Professional Dry Cleaning | Have the fabric professionally dry cleaned using a solvent-based cleaning method. |
| Commercial Heat Treatment | Contact a textile manufacturer or fabric treatment facility for specialized heat treatment options. |
Maintaining Shrinkage over Time
Once you have successfully shrunk your 100% polyester item, it is important to take steps to maintain its shrunken size over time. Here are some tips to help you keep your polyester clothing or fabric looking its best:
Wash in Cold Water
Always wash your shrunk polyester items in cold water. Hot water can cause the fibers to relax and stretch, which will shrink the fabric less effectively. Cold water, on the other hand, helps to keep the fibers in place, preserving the shrunken size.
Use a Gentle Cycle
When washing your shrunk polyester items, select the gentle cycle on your washing machine. This will help to minimize agitation and prevent the fibers from stretching. Avoid using the normal or heavy-duty cycles, as these can be too harsh and cause the fabric to lose its shape.
Avoid Overdrying
Do not overdry your shrunk polyester items. Overdrying can cause the fibers to become brittle and break, which can lead to shrinking. Remove your items from the dryer as soon as they are dry to the touch. If you are using a dryer, use the lowest heat setting possible.
Hang to Dry
Whenever possible, hang your shrunk polyester items to dry. This will help to prevent them from stretching and losing their shape. Avoid hanging them on a clothesline, as the weight of the wet items can stretch the fabric. Instead, hang them on a hanger or drying rack.
Store Properly
When storing your shrunk polyester items, fold them neatly and store them in a cool, dry place. Avoid storing them in a damp or humid environment, as this can cause the fibers to relax and stretch. If you are storing them for an extended period of time, consider using a vacuum storage bag to help keep them compact.
Avoid Chlorine Bleach
Chlorine bleach can weaken the fibers of polyester, causing them to stretch and lose their shape. Avoid using chlorine bleach on your shrunk polyester items. If you need to bleach them, use a non-chlorine bleach instead.
Iron on Low Heat
If you need to iron your shrunk polyester items, use the lowest heat setting possible. High heat can damage the fibers and cause them to stretch. Use a pressing cloth to protect the fabric from the direct heat of the iron.
Dry Clean
If your shrunk polyester items are heavily soiled or delicate, you may want to consider dry cleaning them. Dry cleaning is a gentler process than home laundering and can help to preserve the shrunken size of your items.
