The object of the sublimation calender transfer machine can be a tough material or a soft material. And it can be printed on inorganic materials or printed on organic materials. And the device has stronger adaptability to materials, avoiding the emergence of various problems. It is also a new printing and dyeing process that has gradually emerged in the world in recent years.
A. Melting method: The ink layer of the transfer paper is composed of dye and wax as the basic component, and the ink layer is embedded into the fabric by melt pressing, so that part of the ink is transferred to the fiber, and then corresponding post-treatment according to the nature of the dye. When the melting method is employed, a large pressure is required. And the transfer rate of the dye increases as the pressure increases.
B. Ink layer peeling method: using ink which can strongly adhere 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 according to the nature of the dye. Fixing treatment.
C. Sublimation method: This is the most commonly used method, using the sublimation characteristics of disperse dyes, using a molecular weight of 250 ~ 400, particle diameter of 0.2 ~ 2 microns of disperse dyes and water-soluble carriers or alcohol-soluble carriers (such as ethyl An ink made of cellulose or oil-soluble resin is treated on a transfer printing machine at 200 to 230 ° C for 20 to 30 seconds to transfer the disperse dye to a synthetic fiber such as polyester and fixed.
D. Migration method: The dye in the ink layer of the transfer paper is selected according to the properties of the fiber. The fabric is firstly padded by a mixture of fixing agent and paste, and then transferred by hot pressing in a wet state to transfer the dye from the transfer printing paper to the fabric and fixed, and finally steamed and washed. Wait for wet treatment. When the dye is transferred, a large pressure is required between the fabric and the transfer paper.
