Fabric inks are designed for natural fibers. The problem is not the ink printing onto the fabric it is the curing process; - The ink needs to hit a certain temperature in order to cure onto fabric, so that the garment can be washed. Natural fibers such as cotton can take higher temperatures than synthetic fibers. - When you try to cure the ink onto synthetic materials you may find that the fabric melts / puckers or scorches. You would need to test the fabric to see what happens. There are additives that you can buy to mix with your ink in order to bring the cure temperature down so that the synthetic material is not affected, or another additive that can cure the ink with air over a number of days. With any ink additives you should only mix the amount of ink you require for the print run you are doing that day, otherwise it could set the ink in the container. Different ink brands will have different products that are designed to work with their ink only, so it is wise to stay with the same brand. Please remember that you should always test any inks and any ink additive on the material before you commit to a print run. Suggested testing is to print – cure – wash – rub / scrub / scratch the printed area. This way you can see what the final result would be.
