Tips To Apply Iron-on Patches To Polyester

Tips To Apply Iron-on Patches To Polyester

If you don’t desire your polyester fabric to catch fire and get burned, then you can take some precautionary measures. Here are some precautions to take while applying Iron-on patches to the polyester fabric;

1. Firstly, start by setting your iron to the lowest heat temperature. This will ensure that your polyester fabric doesn’t get ruined by the high temperature all of a sudden. Additionally, it is harder to generate fire like this. 

2. Make sure that you don’t use any steam, as when the patch gets wet; it won’t get attacked properly.

3. Use a piece of parchment paper or any thin material like cotton. It is to cover the patch, so you need not move around it. If you decide not to use cotton, more heat will be applied to the polyester fabric, and the fabric will catch fire easily.

4. Make sure that you have one layer of polyester below the patch. Polyester is a delicate material, and if you place the second layer below the first, then the adhesive will flow to another layer as well. It may damage the fabric. If you don’t watch it out, you will stick the back and front of the fabric together. You cannot even undo that.

5. While ironing, try to make circular motions on the patch for about 30 to 40 seconds as the temperature is lower.
