What Setting On Iron For Polyester?

Ironing clothes made of polyester requires attention to temperature and technique to avoid damaging the fabric. If you’re short on time, here’s a quick answer to your question: use a medium heat setting between 300-320°F or 150-160°C.

In this comprehensive guide, we’ll cover everything you need to know about ironing polyester fabric. We’ll discuss optimal iron temperatures, special care instructions, the pros and cons of different ironing methods, and tips to make your polyester clothes look crisp and wrinkle-free.

The Basics of Ironing Polyester

Polyester is a popular fabric known for its durability and wrinkle-resistant properties. However, ironing polyester requires some special care to avoid damaging the fabric. Here are some important factors to consider when ironing polyester:

Polyester’s Heat Sensitivity

Polyester is heat sensitive, meaning it can melt or warp if exposed to high temperatures. Unlike natural fibers such as cotton or linen, polyester requires a lower heat setting to prevent damage. The recommended temperature for ironing polyester is usually around 300 to 350 degrees Fahrenheit (150 to 175 degrees Celsius).

It is crucial to avoid setting the iron on a higher heat as it can cause the fabric to shrink or lose its shape.

Reading Garment Care Labels

Before ironing any polyester garment, it is essential to read the care label. The care label provides instructions on the appropriate ironing temperature for the fabric. Look for symbols or text that indicate the maximum temperature the fabric can withstand.

Following these instructions will help ensure that you iron your polyester garments safely without any damage.

Additionally, some polyester blends may have different care instructions, so it’s important to check the label for any specific guidelines. For example, a polyester-cotton blend may require a lower iron temperature compared to pure polyester.

Choosing the Right Iron Temperature

When ironing polyester, it’s best to start at a low temperature and gradually increase if necessary. Set your iron to the lowest polyester setting and test it on a small, inconspicuous area of the garment. If the fabric reacts well, you can continue ironing at that temperature.

If the wrinkles persist, you can gradually increase the temperature until you achieve the desired results.

It’s worth mentioning that using a steam iron can be beneficial when ironing polyester. The steam helps to relax the fabric, making it easier to remove wrinkles. However, be cautious not to use too much steam or hold the iron in one place for too long, as excessive moisture can damage the polyester fibers.

Tips for Ironing Polyester

Polyester is a popular fabric known for its durability and wrinkle-resistant properties. However, ironing polyester requires some special care to ensure that you don’t damage the fabric. Here are some helpful tips to keep in mind when ironing polyester:

Use a Press Cloth

When ironing polyester, it’s important to use a press cloth to protect the fabric. A press cloth is a thin piece of fabric that acts as a barrier between the iron and the polyester. It helps to prevent the iron from directly touching the fabric, which can cause shiny marks or even melt the polyester fibers.

You can use a clean cotton cloth or a muslin fabric as a press cloth. Simply place it over the polyester garment and iron over it.

Iron on Low Heat

Polyester is a synthetic fabric that is sensitive to heat. High heat can cause the fabric to melt or shrink. Therefore, it’s essential to set your iron to a low heat setting when ironing polyester. Most irons have a polyester or synthetic fabric setting, which is usually indicated by a single dot or a low heat symbol.

Make sure to adjust the temperature accordingly to avoid damaging the fabric.

Iron on the Reverse Side

Another useful tip for ironing polyester is to iron the garment on the reverse side. By doing so, you minimize the risk of direct heat exposure to the fabric. This helps to protect the polyester fibers and prevent any potential damage.

If you’re ironing a printed or embroidered polyester garment, ironing on the reverse side can also help to preserve the design and prevent any distortion.

Avoid Ironing Directly on Decorations

If your polyester garment has any decorations, such as patches, sequins, or appliques, it’s best to avoid ironing directly on them. These decorations can be delicate and may not withstand the heat of the iron.

Instead, turn the garment inside out and iron around the decorations or use a press cloth to protect them. This will ensure that your polyester garment stays in good condition without any damage to the decorations.

By following these tips, you can safely and effectively iron your polyester garments without causing any damage. Remember to always check the care instructions on the garment label and test a small inconspicuous area before ironing the entire garment.

With the right techniques, you can keep your polyester clothes looking great and wrinkle-free!

Common Ironing Mistakes to Avoid

Using Excessive Heat

One of the most common mistakes people make when ironing polyester is using excessive heat. Polyester is a delicate fabric that can easily melt or get damaged if exposed to high temperatures. To avoid this, it is important to set the iron to the correct temperature for polyester.

Typically, a low to medium heat setting is suitable for polyester fabrics. It is always recommended to check the care label on the garment for specific ironing instructions.

Did you know? Polyester is a synthetic fabric that is known for its durability and wrinkle-resistant properties. It is commonly used in clothing, upholstery, and other household items.

Ironing Decorated Areas

Ironing over decorated areas can also lead to irreversible damage to your polyester garment. Decorations such as prints, embroidery, or sequins can melt or warp when in direct contact with the iron. To avoid this, it is best to iron around these areas or use a pressing cloth to protect the decoration.

A pressing cloth acts as a barrier between the iron and the fabric, preventing any direct heat contact.

Pro tip: If you’re unsure about ironing over a decorated area, it’s always better to err on the side of caution and avoid ironing it altogether.

Leaving the Iron Facedown

Leaving the iron facedown on your polyester fabric for an extended period of time can result in scorch marks or even melting. This is a mistake that can easily be avoided by always keeping the iron in an upright position when not in use.

Additionally, it is important to use an ironing board or a heat-resistant surface to prevent any damage to your iron or fabric.

Fun fact: Did you know that the first electric iron was invented in the late 19th century? It revolutionized the way people pressed their clothes and made ironing much more convenient.

Caring for Polyester Garments

Polyester is a popular fabric choice for many garments due to its durability, wrinkle resistance, and ease of care. To ensure that your polyester garments stay in great condition for longer, it is essential to follow proper care instructions. Here are a few tips for caring for polyester garments:

Follow Washing Instructions

When it comes to washing polyester garments, it is important to always check the care label for specific instructions. In general, polyester can be machine washed on a gentle cycle with cold water. Avoid using hot water as it can cause the fabric to shrink or lose its shape.

Additionally, use a mild detergent that is suitable for synthetic fabrics. Avoid using bleach or fabric softeners as they can damage the fabric fibers. Once the washing cycle is complete, remove the garment promptly to prevent wrinkles from setting in.

Line Dry or Use Low Heat

After washing, polyester garments can be air-dried by hanging them on a clothesline or drying rack. This method helps to maintain the shape and quality of the fabric. If you prefer to use a dryer, set it to a low heat setting or use the delicate cycle.

Excessive heat can cause polyester to shrink or become damaged. To reduce static cling, consider using dryer balls or a fabric softener sheet.

Store Properly to Avoid Wrinkles

Proper storage is essential to keep polyester garments wrinkle-free. Hanging polyester garments on hangers can help maintain their shape and prevent creases. If folding is necessary, fold them neatly and store them in a drawer or on a shelf where they won’t get crushed.

If you notice any wrinkles on your polyester garment, you can use a steamer or an iron with a low heat setting to remove them. However, be cautious while using an iron and always test a small, inconspicuous area of the garment first to prevent any damage.

By following these care tips, you can keep your polyester garments looking great for a long time. Remember to always read and follow the care instructions provided by the manufacturer to ensure the best results.

When to Dry Clean Instead

While polyester is a durable and versatile fabric, it does require some special care when it comes to ironing. In some cases, it may be best to skip the iron altogether and opt for dry cleaning. Here are a few instances when dry cleaning is the better option:

Delicate or Heavyweight Polyester

Delicate polyester fabrics, such as chiffon or satin, can be easily damaged by high heat from an iron. If you’re unsure about the setting to use or if the fabric is particularly delicate, it’s best to play it safe and take it to a professional cleaner.

On the other hand, heavyweight polyester fabrics, like those used in upholstery or heavy curtains, may be difficult to iron properly at home. These fabrics require a lot of heat and pressure to remove wrinkles, which can be challenging to achieve with a regular household iron.

Taking them to a professional cleaner ensures that they will be properly steamed and pressed, leaving them looking their best.

Formalwear and Suits

When it comes to formalwear and suits made from polyester, it’s generally recommended to have them dry cleaned rather than attempting to iron them at home. These garments often have intricate detailing, such as pleats or delicate embellishments, that can be easily damaged by an iron.

Dry cleaning not only removes any wrinkles but also ensures that the garments are handled with care and attention to detail.

Intricate Embellishments

If your polyester garment has intricate embellishments, such as beading or embroidery, it’s best to avoid ironing it at home. The heat and pressure from an iron can cause these embellishments to become loose or even melt.

Instead, take the garment to a professional cleaner who can safely remove wrinkles and preserve the integrity of the embellishments.

Remember, when in doubt, it’s always better to err on the side of caution and take your polyester clothing to a professional cleaner. They have the expertise and knowledge to handle delicate fabrics and intricate details, ensuring that your garments look their best for years to come.


By following the proper techniques for ironing polyester, you can keep your clothes looking crisp without risking damage. Pay attention to garment care labels, use a medium heat setting, and avoid leaving the iron in one place too long.

With the right temperature and a few simple tips, you can easily iron polyester fabrics at home.
