Polyester is a popular synthetic fabric used in a wide range of clothing and textiles. It’s known for its durability, wrinkle resistance, and ease of care. However, one common concern when it comes to washing polyester is whether it will shrink in hot water. In this article, we’ll explore the properties of polyester, the effects of hot water on the fabric, and provide tips on how to wash and care for polyester garments to prevent shrinkage.
Understanding Polyester Fabric
Polyester is a synthetic fabric made from petrochemicals, which are derived from oil. It’s produced through a process called polymerization, where the petrochemicals are combined with other chemicals to create a strong and durable fabric. Polyester is often blended with other fibers, such as cotton or rayon, to create a fabric with unique properties.
Types of Polyester Fabric
There are several types of polyester fabric, each with its own unique characteristics. Some common types of polyester fabric include:
- Microfiber polyester: This type of polyester is known for its softness and fine texture. It’s often used in clothing and textiles that require a high level of softness and drape.
- Taffeta polyester: This type of polyester is known for its crisp texture and rustling sound. It’s often used in clothing and textiles that require a high level of structure and stability.
- Fleece polyester: This type of polyester is known for its warmth and thickness. It’s often used in clothing and textiles that require a high level of insulation and warmth.
The Effects of Hot Water on Polyester
Hot water can have a significant impact on polyester fabric. When polyester is exposed to hot water, the fibers can shrink and lose their shape. This is because the heat causes the fibers to contract and tighten, leading to a reduction in size.
Why Does Polyester Shrink in Hot Water?
There are several reasons why polyester shrinks in hot water. Some of the main reasons include:
- Thermal contraction: When polyester fibers are exposed to heat, they contract and tighten. This can cause the fibers to shrink and lose their shape.
- Moisture absorption: Polyester fibers can absorb moisture from the water, which can cause them to swell and shrink.
- Fiber relaxation: When polyester fibers are exposed to heat, they can relax and lose their tension. This can cause the fibers to shrink and lose their shape.
How to Wash Polyester to Prevent Shrinkage
While it’s impossible to completely prevent shrinkage, there are several steps you can take to minimize the risk of shrinkage when washing polyester. Here are some tips:
- Wash in cold water: Cold water is less likely to cause shrinkage than hot water. Try to wash your polyester garments in cold water to minimize the risk of shrinkage.
- Use a mild detergent: A mild detergent can help to minimize the risk of shrinkage. Avoid using harsh detergents or those that contain bleach or fabric softener.
- Avoid over-drying: Over-drying can cause polyester fibers to shrink and lose their shape. Try to remove excess water from your garments without over-drying them.
- Reshape while wet: Reshaping your garments while they’re still wet can help to prevent shrinkage. Try to reshape your garments to their original dimensions while they’re still wet.
Special Care Instructions for Polyester Garments
Some polyester garments may require special care instructions to prevent shrinkage. Here are some examples:
- Delicate polyester garments: Delicate polyester garments, such as lingerie or activewear, may require special care instructions. Try to wash these garments in cold water and avoid using harsh detergents.
- Polyester garments with beads or sequins: Polyester garments with beads or sequins may require special care instructions. Try to avoid washing these garments in hot water, as the heat can cause the beads or sequins to loosen or fall off.
Conclusion
Polyester is a popular synthetic fabric that’s known for its durability and ease of care. However, it can shrink in hot water, which can cause it to lose its shape and size. By understanding the properties of polyester and taking steps to minimize the risk of shrinkage, you can help to keep your polyester garments looking their best.

Will Polyester Shrink if Washed in Hot Water?
Polyester is generally resistant to shrinkage, but washing it in hot water can cause some degree of shrinkage. The extent of shrinkage depends on various factors, including the type of polyester fabric, the temperature of the water, and the washing method. If you wash polyester in hot water, it may shrink slightly, but the shrinkage is usually minimal.
However, it’s essential to note that some types of polyester fabrics are more prone to shrinkage than others. For example, polyester blends or fabrics with a loose weave may shrink more than 100% polyester fabrics with a tight weave. To minimize the risk of shrinkage, it’s recommended to wash polyester in cold water and avoid using high heat when drying.
What Happens When You Wash Polyester in Hot Water?
When you wash polyester in hot water, the fibers can contract and tighten, leading to a slight shrinkage. The heat can also cause the fibers to break down, which can affect the fabric’s texture and appearance. In some cases, washing polyester in hot water can cause the fabric to lose its shape or become misshapen.
However, it’s worth noting that modern polyester fabrics are designed to be more resistant to shrinkage and heat damage. Many polyester fabrics are treated with special finishes that help to reduce shrinkage and improve their durability. If you do need to wash polyester in hot water, make sure to check the care label first and follow any specific washing instructions.
How to Prevent Polyester from Shrinking in the Wash?
To prevent polyester from shrinking in the wash, it’s recommended to wash it in cold water. Cold water helps to preserve the fibers and prevent them from contracting and tightening. You should also avoid using high heat when drying polyester, as this can cause the fibers to break down and lead to shrinkage.
In addition to washing in cold water, you can also take other steps to prevent polyester from shrinking. For example, you can use a mild detergent that’s designed for washing synthetic fibers. You should also avoid wringing or twisting the fabric, as this can cause it to stretch or shrink. Instead, gently remove excess water from the fabric and lay it flat to dry.
Can You Unshrink Polyester Fabric?
If you’ve accidentally shrunk a polyester fabric, there are a few things you can try to unshrink it. One method is to soak the fabric in a solution of warm water and a fabric relaxer. The fabric relaxer can help to relax the fibers and restore the fabric to its original shape.
However, it’s essential to note that unshrinking polyester fabric can be a tricky process, and the results may vary. In some cases, the fabric may not return to its original shape or size. To avoid this, it’s always best to follow the care instructions and take steps to prevent shrinkage in the first place.
What is the Best Way to Wash Polyester?
The best way to wash polyester is to use cold water and a mild detergent. You should also avoid using fabric softener or bleach, as these can damage the fibers and cause them to break down. When washing polyester, it’s also a good idea to use a gentle cycle with a slow agitation.
In addition to using cold water and a mild detergent, you should also avoid overloading the washing machine. This can cause the fabric to stretch or shrink, especially if it’s a delicate or loose-weave fabric. Instead, wash polyester fabrics separately or with similar fabrics to prevent damage.
