Iron-on vinyl transfer products work best on 100% cotton fabrics, but can also be used on simple polyester.  As a natural fibre, cotton is perfect for allowing t-shirt vinyl to easily adhere and remain for use after use and wash after wash.

Cotton and polyester blends will also withstand heat and will work well with heat press vinyl, which means you may even be able to get really creative and start printing on complex garments and apparel such as caps and scarves!

Some polyester, however, may not respond well to some heat products.  The vast majority of our heat transfer vinyl is designed and produced to adhere to such material, however, and providing you set your heat press to no more than 270˚F / 130˚C, you will run no risk of melting the fabric.

As a general rule, we do recommend that you consider running a test print and press before you oversee a larger production run.
