1. sublimation method
This is the most commonly used method, using the sublimation characteristics of disperse dyes, using disperse dyes with a molecular weight of 250-400 and a particle diameter of 0.2-2 microns and a water-soluble carrier (such as sodium alginate) or an alcohol-soluble carrier (such as ethyl alcohol). Base cellulose), oil-soluble resin to make ink, and process it on a transfer printing machine at 200-230°C for 20-30 seconds, so that the dispersed dyes can be transferred to synthetic fibers such as polyester and fixed.
2. swimming method
The dye in the sublimation transfer paper ink layer is selected according to the nature of the fiber. The fabric is first treated by padding with a mixture of color-fixing aids and pastes, and then in a wet state by hot-pressing swimming to transfer the dye from the transfer printing paper to the fabric and fix it. Finally, it is steamed and washed. Wet treatment. When the dye is transferred, greater pressure is required between the fabric and the transfer paper.
3. fusion method
The ink layer of sublimation transfer paper is based on dyes and waxes. By melting and pressing, the ink layer is embedded into the fabric, so that part of the ink is transferred to the fiber, and then corresponding post-treatment is performed according to the properties of the dye. When using the melting method, greater pressure is required, and the transfer rate of the dye increases with the increase of the pressure. the
4. ink layer peeling method
Use the ink that can produce strong adhesion to the fiber after being heated, and the entire ink layer can be transferred from the transfer paper to the fabric under a small pressure, and then perform corresponding color-fixing treatment according to the properties of the dye.
Sublimation transfer printing process
The various styles, colors, and patterns required by customers are designed by computer --- computer color separation --- electric engraving plate-making --- wheel gravure printing to heat transfer paper --- heat transfer processing to polyester chemical fiber On different materials such as fabrics, TC cloth, plush fabrics, artificial leather, etc., this printing process is more traditional silk screen printing and dyeing printing. , washability, sun fastness, and hand feel have been greatly improved. It is a popular printing and dyeing process that is highly respected in the world and products are becoming high-end in the 21st century.
