Tips to heat press Polyester

Remember different types of Polyester.

Just because Polyester is used in so many garments doesn’t mean it’s all the same. There are many types & qualities of Polyester used in different clothes, so make sure to check your tags before purchase. You may need to try out a few by heat pressing before finalizing.

If you’re working with a large batch of shirts or material, do a small test run before committing to the whole thing. Cut off a small swatch of Polyester, heat-press it with your iron on high heat for 10 seconds, and then wash it three times before determining the softness.

If your fabric is made out of certain materials like waterproof or Polyester, you might find it mentioned on the tag that it’s heat sensitive or not to be ironed. If that’s the case, then you need HTV with a lower release temperature.

The melting point of the Polyester is low.

For Polyester, it is better to start with a lower temperature and then gradually increase the temperature. If you are having trouble getting your HTV to stick, this method will help. But if it scorches and discolors your shirt, there is no undoing it because the melting point of polyester is low.

Try preheating Polyester

Unlike cotton, preheating Polyester won’t break down the fibers to open them up for printing. It does, however, evaporate any water on the surface of your material for a smoother finish. When printing with HTV, it is essential to ensure that the cloth is dry and smooth. As a result, the vinyl adheres appropriately.

Avoid thick silicon sheets.

Placing heat press pillows & silicone sheets to cover irregular materials like zippers or buttons can help you handle them better. However, for a simpler material, it may feel more challenging to get the correct shape.

If you want to use a sheet, our favorite is Teflon because it’s designed for vinyl.

Select compatible heat transfer vinyl

Low-quality vinyl is not suited for HTV work, so you don’t want to skimp when it comes to vinyl products. The trickiest parts of the process are the easiest technique, but it can be even more difficult if you start with a poor-quality product.

It can be challenging to find a dependable company for all your HTV needs. Our experts here at Heated Gadget recommend finding one that offers enough versatility for any occasion and doesn’t require changing your settings each time you pick a different brand. This way, it’s easy for you to stay organized and not go crazy.

Increase heat press duration

Your HTV adhesive has a lower activation temperature than that of polyester fabric. This means that your machine’s default settings are likely to leave the material damaged, so increase the pressing time rather than heating up too much to get perfect press.

The dye should never bleed from the fabric.

When printing on sublimated fabric, take extra care to ensure the transfer doesn’t leak. Standard HTV won’t do the job if you’re trying to block sublimation migration, so if you find that your vinyl’s colors change when applied to fabrics, it means dye to bleed from the fabric.

Be careful when using an iron.

If you’re using iron for polyester heat-press, one of the first things we would recommend trying is changing the heat and time. With a heat press, you can be more precise with how much heat to use and for how long.

If you’re going to use an iron, it’s important not to set it on high and turn off the steam feature.

Use precise settings

Be sure to follow the instructions that are included with your vinyl. If you’re following a heat press tutorial and find that things aren’t going quite right, it might be because you’re using a different brand of vinyl than they are showing.

If you’re not using pure polyester fabric, your settings for temperature and time will be different.
