Most people who want to sublimate a design onto a cotton t shirt will sublimate their image onto what s known as white glitter vinyl.
That s long enough to melt many synthetic fabrics so you must check the heat transfer vinyl instructions to see if you can use it with polyester and other synthetic materials.
This somewhat prevents the dye in the shirt from hitting temperatures to migrate.
