Clothing styles have changed in the past decade and these changes brought with them the trend of active wear as a fashion choice. This means that there is a lot more polyester in fashion than there used to be. From jerseys to athletic leisure the demand for personalized or trendy graphic images on this unforgiving fabric has risen. So, if you are getting into garment enhancement you will want to make sure you understand how to treat this fabric when using a heat press

In this article, we will give you a few tips for the use of a heat press with polyester as well as how to avoid those pesky heat press marks that often plague the T-shirt designed. 

Heat Press Tips for Polyester

Polyester offers a specific challenge that must be addressed, so knowing a few key tips and tricks when handling polyester will help you ensure that your project is delivered with perfection. 

  • Heat is an important thing to monitor. You need heat when pressing graphics onto tees or other products. Some of the fabrics such as polyester are highly susceptible to heat and that may make it challenging. In fact, if you are not careful you could melt your shirt. Typically, you would want your heat at around 300 degrees Fahrenheit but with polyester, the better choice would run it a little cooler like 180 degrees
  • You also need to make sure that you use the right transfer. This is important especially with polyester because some are more affected by heat than others, so making sure to check the heat threshold of the transfer is key
  • You also may want to test the polyester. Use your heat press and try it at the lowest temp for polyester, so around 280 degrees. If it doesn’t scorch, then up the temp by 5 degrees. Only test a small piece until you reach a scorching point and then you have an idea of how hot you can get your heat press
  • One good rule of thumb is to stick with thin cover sheets for the most part. This will allow much more heat to reach your fabric and transfer. Now if you are working with polyester you may consider a slight thicker cover sheet but just remember not too thick
  • You want to pay close attention to dye migration because this happens a lot with polyester. This is when the dye from the original crafting gets heated and activates again and this may cause it to bleed into the graphic design.

These are just a few tips you can use to make working with polyester easier and to decrease the risk of error. By simply taking your time and making sure you understand the composition and reactions of polyester to heat, you are well on the way to being able to add new products to your business.
