Are you wondering if your 60% cotton 40% polyester clothing will shrink? You’re not alone. Many people ask this question, and the answer is not always straightforward.
While some blended fabrics are less prone to shrinkage, cotton-polyester blends are known to shrink under certain conditions.

Here are some things you need to know about 60% cotton 40% polyester clothing and shrinkage:
- Cotton is a natural fiber that has a tendency to shrink when exposed to heat and moisture. Polyester, on the other hand, is a synthetic fiber that is more resistant to shrinkage.
- When cotton and polyester are blended together, the resulting fabric can be more durable and wrinkle-resistant than pure cotton. However, it can still shrink if exposed to high temperatures during washing and drying.
- To minimize shrinkage, it’s important to follow the care instructions on the garment label. Washing in cold water and drying on a low heat setting can help prevent shrinkage. However, if you want to be extra cautious, you can always hand wash and air dry your cotton-polyester blend clothing.
Understanding Cotton and Polyester
If you’re wondering whether a 60% cotton and 40% polyester blend will shrink, it’s important to understand the characteristics of each fabric.
Cotton is a natural fiber derived from the cotton plant. It is a popular choice for clothing due to its softness, breathability, and durability. Cotton is also easy to care for, making it a staple in many wardrobes. However, cotton has a tendency to shrink when exposed to high temperatures during the washing and drying process.
Polyester, on the other hand, is a synthetic fiber made from petrochemicals. It is known for its durability, wrinkle-resistance, and ability to hold its shape. Polyester is also resistant to shrinking and stretching, making it a popular choice for athletic wear and other clothing items that need to retain their shape.
When blended together, cotton and polyester create a fabric that combines the advantages of both materials.
- Natural fibers like cotton are derived from plants or animals, while synthetic fibers like polyester are made from chemicals and petrochemicals.
- Cotton is a natural fabric, while polyester is a synthetic fabric.
- 100% cotton fabrics are more likely to shrink than 100% polyester fabrics.
- Cotton-polyester blends can vary in their cotton content, with some blends containing as little as 50% cotton and others containing as much as 58% cotton.
- A cotton-polyester blend is also known as a polycotton blend.

Shrinkage in Cotton-Polyester Blends
Here are some things you should know about shrinkage in cotton-polyester blends:
- Cotton shrinks more than polyester: Cotton is a natural fiber that is prone to shrinkage. When exposed to high temperatures, cotton fibers will contract and become smaller. Polyester, on the other hand, is a synthetic fiber that is more resistant to heat and does not shrink as much as cotton.
- Higher cotton content means more shrinkage: The more cotton a fabric contains, the more likely it is to shrink. A blend of 60% cotton and 40% polyester will shrink more than a blend of 80% polyester and 20% cotton.
- Hot water and high heat cause more shrinkage: The hotter the water and the higher the heat, the more likely the fabric is to shrink. To minimize shrinkage, wash your cotton-polyester blend in cold water and avoid drying it on high heat. Instead, hang it up to air dry or use a low-heat setting on your dryer.
- Pre-shrunk fabrics are less likely to shrink: Some manufacturers pre-shrink their fabrics before making them into garments. This means that the fabric has already been exposed to high temperatures and is less likely to shrink further. Look for garments that are labeled as pre-shrunk if you are concerned about shrinkage.
Factors Affecting Shrinkage
When it comes to shrinkage, there are several factors that can play a role in how much a 60 percent cotton, 40 percent polyester garment will shrink.
- Heat Exposure: One of the biggest factors that can contribute to shrinkage is heat exposure. If you wash your garment in hot water or dry it on high heat, it is much more likely to shrink than if you use cooler temperatures.
- Agitation: Agitation during the washing and drying process can also contribute to shrinkage. If you wash your garment with other clothes that are heavy or bulky, or if you use the high agitation setting on your washing machine, this can cause the fibers to rub against each other and shrink.
- Fiber Content: While this section is focused on 60 percent cotton, 40 percent polyester garments, it’s worth noting that the specific fiber content can also affect how much a garment shrinks. For example, a garment made with a higher percentage of cotton is likely to shrink more than one with a lower percentage.
- Temperature to Wash: The temperature at which you wash your garment can also play a role in how much it shrinks. Washing in cold water is less likely to cause shrinkage than washing in hot water.
- Temperature to Dry: Similarly, the temperature at which you dry your garment can also affect shrinkage. Drying on low heat or air-drying is less likely to cause shrinkage than drying on high heat.
It’s worth noting that some garments may come pre-shrunk, meaning that they have already been treated to prevent shrinkage. However, even pre-shrunk garments can still shrink if exposed to high heat or agitation. By following the care instructions on the label and using cooler temperatures and gentler settings, you can help minimize shrinkage and keep your garment looking its best.
Care Instructions for Cotton-Polyester Blends
Here are some care instructions you should follow:
- Check the care label: Before washing your cotton-polyester blend garment, always check the care label for specific washing instructions. Follow the instructions carefully to avoid damaging the fabric.
- Washing: You can wash cotton-polyester blend garments in the washing machine, but use cold or warm water, not hot water. Hot water can cause shrinkage. Use a gentle cycle and mild detergent. Avoid using fabric softeners as they can damage the fabric.
- Drying: Air drying is the best option for cotton-polyester blend garments. If you must use a dryer, use a low heat setting. High heat can cause shrinkage. Remove the garment from the dryer while it is still slightly damp to avoid over-drying.
- Hand washing: If you prefer to hand wash your cotton-polyester blend garment, use cool or warm water and a gentle detergent. Do not wring or twist the fabric. Instead, gently squeeze out excess water and lay the garment flat to dry.
- Ironing: Cotton-polyester blend garments can be ironed on a low heat setting. Do not use a high heat setting as it can damage the fabric. Always iron the garment inside out to avoid damaging the outer layer of the fabric.
These care instructions will help you keep your cotton-polyester blend garment looking great and prevent shrinkage. Remember to always check the care label for specific washing instructions and follow them carefully.

Impact of Shrinkage on Clothing
Here are some ways shrinkage can impact clothing:
- Fit: If a garment shrinks, it may no longer fit as well as it did before. This can be especially problematic for items like dresses or suits, where the fit is crucial to the overall look of the outfit.
- Comfort: Shrinkage can also affect the comfort of a garment. If a shirt or pair of pants shrinks, it may become tighter and less breathable, making it uncomfortable to wear.
- Appearance: Shrinkage can also impact the appearance of a garment. For example, if a shirt shrinks, it may become wrinkled or look misshapen. This can make the garment look old or worn out, even if it is relatively new.
- Labeling: Shrinkage can also impact the labeling of clothing. If a garment shrinks significantly, it may no longer fit into the size category listed on the label. This can be confusing for consumers, who may not know which size to choose when purchasing the garment.
- Sewing: Shrinkage can also impact the sewing process. If a fabric shrinks significantly, it may be more difficult to work with, making it harder to sew or alter the garment.
Other Considerations
When it comes to caring for your 60 percent cotton 40 percent polyester clothes, there are a few other things to keep in mind besides the risk of shrinking. Here are some other considerations to keep in mind:
- Moisture: Cotton is known for absorbing moisture, while polyester is known for repelling it. This means that if you sweat a lot while wearing your cotton-polyester blend clothes, they may retain moisture and take longer to dry. To prevent this, consider wearing moisture-wicking undergarments or choosing a different fabric blend altogether.
- Rayon and Viscose: Some cotton-polyester blends also contain rayon or viscose. These materials are known for their softness and drape, but they can also be more delicate and prone to shrinking. If your clothes contain rayon or viscose, be sure to follow the care instructions carefully to avoid damage.
- Pre-Shrunk: Some cotton-polyester blends are pre-shrunk, which means they have already been treated to prevent shrinkage. If you’re concerned about your clothes shrinking, look for pre-shrunk options or consider washing them in cold water and air-drying them to minimize shrinkage.
- Cotton-Polyester Blends: Cotton-polyester blends are popular for a reason – they’re soft, comfortable, and durable. However, they may not be the best choice for every situation. For example, if you need clothes that are moisture-wicking or quick-drying, you may want to consider a different fabric blend. Be sure to consider your needs and preferences when choosing clothes made from cotton-polyester blends.
Remember, each fabric blend has its own unique properties and care instructions. By taking the time to understand how to care for your 60 percent cotton 40 percent polyester clothes, you can help ensure they look great and last for years to come.
