This is the most commonly used method. It uses the sublimation characteristics of disperse dyes, uses disperse dyes with a molecular weight of 250~400 and a particle diameter of 0.2~2 microns, water-soluble carriers or alcohol-soluble
Carriers, and oil-soluble resins to make ink, and processes it on a transfer printing machine at 200~230 C for 20~30 seconds to transfer the disperse dyes to synthetic fibers such as polyester and fix them.
The ink layer of thermal transfer paper is based on dyes and waxes. Through melting and pressurization, the ink layer is embedded in the fabric, so that part of the ink is transferred to the fiber, and then the corresponding post-processing is performed according to the properties of the dye. When using the melting method, a larger pressure is required, and the transfer rate of the dye increases with the increase of pressure.
The dye in the ink layer of the transfer paper is selected according to the properties of the fiber. The fabric is first treated with a mixture of a fixing agent and a paste, and then the dye is transferred from the transfer paper to the fabric and fixed by hot pressing migration in a wet state, and finally wet treatments such as steaming and washing are performed. When the dye is transferred, a large pressure is required between the fabric and the transfer paper. 4. Ink layer peeling method: Using ink that can produce strong adhesion to the fiber when heated, the entire ink layer can be transferred from the transfer paper to the fabric under a small pressure, and then the corresponding color fixing treatment is performed according to the nature of the dye.
