Transfer printing refers to a printing system in which dye is first printed on a paper substrate and then transferred from paper to cloth. Most of the dyes used in transfer printing belong to disperse dyes and a few are solvent dyes. Therefore, heat transfer printing is most commonly used in nylon and polyester. It is also used in acrylic, triacetate, and polyester-cotton blended fabrics with a high content of polyester. Although there is a lot of research on heat transfer printing for other fibers, there is no feasible process for actual production.
