What is Polyester: Does Polyester Shrink?

Determining ‘Does polyester shrink?’ is one common concern about polyester. Polyester is a synthetic fabric made from polyester fibers, essentially a plastic-type. While some polyester is made with plant materials, the majority is petroleum-based. It can be easily dyed or chemically treated with unique characteristics like flame-retardancy or anti-microbial properties. 

Polyester’s versatility extends beyond clothing to upholstery and various other applications due to its lightweight nature and ease of care. By comprehending the composition and diverse types of polyester fabrics available, individuals can effectively maintain and prolong the lifespan of their polyester garments. 

Types of Polyester

Each polyester type offers unique advantages, catering to diverse needs across industries ranging from fashion and sportswear to industrial and technical applications. Polyester’s versatility drives innovation, pushing textile technology and material engineering boundaries. Check out these polyester types to discover their specific benefits:

• PET (Polyethylene Terephthalate): Commonly used in clothing and fabric production due to its strength, durability, and color retention. It has excellent shape-retaining properties, making it suitable for PET bottles, too.
• PCDT Polyester: Ideal for sportswear and activewear because of its moisture-wicking capabilities, which keep the wearer dry during physical activities. PCDT polyester is also valued for its softness and stretch.
• PEN (Polyethylene Naphthalate): Known for exceptional durability and resistance to high temperatures, it is suitable for demanding applications such as industrial fabrics, automotive components, and electrical insulation.

Does Polyester Shrink?

While polyester is more resistant to shrinking than cotton or wool, it can still shrink with repeated washing and drying at high temperatures. Proper care and following garment-specific instructions are essential to maintain its shape and size over time. Here are some key factors explaining why polyester can shrink:

• Heat Sensitivity: Polyester is sensitive to high temperatures. When exposed to heat, the fibers can constrict and tighten, causing the fabric to shrink. This is particularly true if the fabric is washed or dried using high heat settings.
• Washing and Drying: Regular washing and drying of polyester garments, especially in hot water and high heat settings, can lead to shrinkage over time. The agitation and heat during these processes can cause the fibers to compress and reduce size.
• Fabric Construction: How polyester fabric is constructed can influence its susceptibility to shrinkage. Fabrics with a looser weave or knit can be more prone to shrinking compared to tightly woven polyester fabrics.
• Quality of the Fabric: The quality of the polyester can impact its shrinkage properties. Lower-quality polyester fibers or fabrics may be less stable and more likely to shrink when exposed to heat.
• Blend with Other Fibers: Sometimes polyester is blended with other fibers like cotton. In such blends, the shrinkage behavior of polyester can be influenced by the other fibers present in the fabric.

How to Prevent Polyester from Shrinking?

Polyester can be prone to shrinking if not handled correctly during washing and drying. With the right approach, you can keep your favorite polyester garments looking great and fitting perfectly for the long haul. Follow these simple steps to keep your polyester garments looking great and fitting perfectly for a long time.

Step 1: Check Care Label Instructions

Before washing your polyester garment, always check the care label for specific washing guidelines. These guidelines provide crucial insights into the most suitable method for washing and drying your garment to prevent any potential for polyester shrinkage.

• Temperature Settings: The care label guides you on the proper water temperature for washing. Polyester, commonly found in basic tees, typically works best with lukewarm water instead of hot water to preserve the fabric’s integrity and avoid harm.
• Washing Cycle: Look for the recommended washing cycle specified on the label, such as gentle or delicate. This approach ensures the garment is washed appropriately, minimizing wear and tear over time.
• Detergent Type: Check the label for detergent guidance. Some detergents can be too harsh for polyester, potentially affecting its longevity. Using a suitable detergent helps maintain the fabric’s quality.
• Bleaching: Verify if chlorine bleach or other bleaches should be avoided. Bleach can weaken polyester fibers and lead to discoloration, so following the label’s instructions is essential.
• Drying Instructions: The label will advise on drying methods, such as tumble dry low or air dry. Avoid overheating, as it can cause polyester to shrink or damage the fabric.
• Ironing: Note whether ironing is recommended and at what temperature. Polyester can melt under high heat, so follow the label’s instructions to prevent damage.
• Special Care: Some garments may require special care, such as dry cleaning only or specific washing techniques. Pay attention to these instructions to maintain the garment’s quality and longevity.

Step 2: Choose Gentle Wash Cycle

Once you’re done with checking care label instructions, it’s time to choose the delicate wash option on your laundry appliance. Opt for cooler water instead of hot to evade fabric damage. This setting ensures that the polyester garment is treated with care and not subjected to harsh agitation or high heat that can damage the fabric. 

You can help maintain the integrity and shape of your polyester clothing, prolonging its lifespan and keeping it looking great after wear by opting for a gentle wash cycle. Embrace this routine for all your polyester pieces to uphold their top-notch condition.

Step 3: Use Mild Laundry Detergent

Now that you’re done choosing a gentle wash cycle, it’s essential to select a mild fabric conditioner or detergent crafted specifically for delicate fabrics. Abrasive cleansers may harm the polyester fibers, leading to quicker deterioration and increased polyester shrinkage. Mellow detergents exhibit tenderness towards synthetic fabrics and uphold material integrity.

This measure guarantees that your polyester attire maintains peak condition over prolonged durations, diminishing shrinkage probabilities and conserving garment excellence. You can proficiently clean your polyester items utilizing a mild detergent exclusively engineered for delicate fabrics, evading unnecessary polyester shrinkage.

Step 4: Avoid High Heat Settings

When drying polyester, avoid high heat settings, which can cause shrinkage. Opt for low heat or air drying to preserve the fabric. High heat can harm the polyester fibers, causing them to contract and your garment to shrink. Opt for cooler temperatures, such as a low or medium heat setting on your dryer, or air dry your polyester items instead. 

You can maintain the integrity of the fabric and keep your polyester clothing in prime condition for longer by avoiding extreme heat. Use this step to preserve your polyester’s shape and size.

Step 5: Air Dry Whenever Possible

With your optimized heat settings in hand, employ the air drying technique to uphold the form and hue of your polyester garments. Suspend them on a clothesline or drying rack. This delicate approach removes polyester shrinkage, conserving the fabric’s contour and dimensions. Air drying equally mitigates the hazard of overheating polyester fibers, assuring their resilience and endurance. 

Step 6: Consider Wool Dryer Balls

To prevent polyester from shrinking, consider using wool dryer balls when drying polyester items in the dryer. These balls help circulate air around the garments, allowing them to dry faster without excessive heat or agitation that could cause shrinkage. Additionally, wool dryer balls can help reduce static cling, which is beneficial for polyester fabrics.

Wool dryer balls offer a sustainable, eco-conscious substitute for dryer sheets, fostering natural fabric softening without extra chemicals. You can preserve garment integrity, curbing the risk of polyester shrinkage by integrating wool dryer balls into your laundry regimen.

How to Shrink Polyester on Purpose?

If you want to shrink polyester fabric intentionally, try a few tricks. While polyester is known for its resistance to shrinking, you can encourage some size reduction with the proper techniques. Here’s how to go about it:

1. Wash in Hot Water: Polyester usually doesn’t shrink much, but exposure to hot water can help. Use the hottest water setting on your washing machine. This approach will relax the fibers and encourage some polyester shrinkage.
2. Use a Hot Dryer: Transfer the polyester fabric to a hot dryer setting after washing. The heat from the dryer can further shrink it. Watch the iron’s heat to avoid melting the polyester fabric.
3. Monitor Carefully: Polyester can be sensitive to high temperatures, so watch the fabric closely as it dries. Adjust the dryer settings if needed to prevent damage.
4. Repeat if Necessary: Feel free to repeat the process if the fabric hasn’t shrunk enough after the first wash and dry. Multiple cycles of hot water and high heat can gradually shrink polyester.
5. Consider Steam: Steam can also help shrink polyester. Hold a steam iron close to the fabric without touching it, and gently steam the areas you want to shrink while pulling on the fabric.
6. Consult Care Labels: Always check the care label first. Some polyester blends or specialty fabrics may react poorly to these shrinking methods.
7. Proceed with Caution: Remember that intentionally shrinking polyester can be unpredictable. Depending on the fabric blend and manufacturing process, results may vary. Be prepared for the possibility of unintended consequences, like damage or unwanted changes in texture.
