1. Sublimation method: This is the most commonly used method. Using the sublimation characteristics of disperse dyes, disperse dyes with molecular weight of 250 ~ 400 and particle diameter of 0.2 ~ 2 microns, water-soluble carrier or alcohol-soluble carrier and oil-soluble resin are used to make ink, which is processed on a 200 ~ 230C transfer printing machine for 20 ~ 30 seconds to transfer the disperse dyes to synthetic fibers such as polyester and fix them.
　　2. Melting method: the ink layer of heat transfer paper takes dye and wax as the basic components. Through melting and pressurization, the ink layer is embedded into the fabric to transfer part of the ink to the fiber, and then make corresponding post-treatment according to the properties of the dye. When the melting method is used, a large pressure is required, and the dye transfer rate increases with the increase of pressure.
　　3. Swimming method: transfer the dye in the ink layer of paper, which is selected according to the properties of the fiber. The fabric is first soaked and rolled with a mixture of color fixing additives and pastes, and then the dye is transferred from the transfer printing paper to the fabric and fixed by hot press swimming in the wet state. Finally, it is subjected to wet treatment such as steaming and washing. During dye transfer, there needs to be a large pressure between the fabric and the transfer paper.
　　4. Ink layer stripping method: using the ink that can produce strong adhesion to the fiber after heat, the whole ink layer can be transferred from the transfer paper to the fabric under a small pressure, and then the corresponding color fixing treatment can be carried out according to the properties of the dye.
