  There are several common ways to use heat transfer paper:

  1. Sublimation method

  This is the most commonly used method. Using the sublimation characteristics of disperse dyes, disperse dyes with a molecular weight of 250-400 and a particle diameter of 0.2-2 microns are used together with water-soluble carriers (such as sodium alginate) or alcohol-soluble carriers (such as ethyl acetate). Base cellulose) and oil-soluble resin are used to make inks, which are processed on a transfer printing machine at 200-230°C for 20-30 seconds to transfer and fix disperse dyes to synthetic fibers such as polyester.

  1. Swimming method

  The dye in the ink layer of the transfer paper is selected according to the nature of the fiber. The fabric is first subjected to padding treatment with a mixture of fixing aids and pastes, and then in a wet state by hot-pressing migration, so that the dye is transferred from the transfer printing paper to the fabric and fixed, and finally steamed and washed Isotonic treatment. During dye transfer, a greater pressure is required between the fabric and the transfer paper.

  1. Melting method

  The ink layer of the transfer paper is based on dyes and waxes. The ink layer is embedded in the fabric by melting and pressing, so that part of the ink is transferred to the fiber, and then the corresponding post-treatment is performed according to the nature of the dye. When using the melting method, a greater pressure is required, and the dye transfer rate increases with the increase of pressure.

  1. Ink layer peeling method

  Using the ink that can produce strong adhesion to the fiber when exposed to heat, the entire ink layer can be transferred from the transfer paper to the fabric under a small pressure, and then the corresponding fixing treatment can be done according to the nature of the dye.
