Method for implementing transfer printing by utilizing thermal-dye-sublimation transfer printing film

Abstract

The invention belongs to the technical field of thermal transfer printing films, and particularly relates to a method for implementing transfer printing by utilizing a thermal-dye-sublimation transfer printing film. The method comprises the following steps of: (1) making the thermal-dye-sublimation transfer printing film into a cylindrical pipeline with a basic film being arranged inside the cylindrical pipeline according to the size of a body to be subjected to transfer printing; (2) coating polyurethane resin on the surface of the body to be subjected to transfer printing, and then drying the body to be subjected to transfer printing for 3 to 5 minutes at the temperature of 180 to 200 DEG C; (3) inserting the coated body to be subjected to transfer printing into the cylindrical pipeline which is made of the thermal-dye-sublimation transfer printing film in (1); and (4) preheating the cylindrical pipeline holding the coated body to be subjected to transfer printing for 30 to 60 seconds at the temperature of 40 to 60 DEG C and finally heating for 3 to 5 minutes at the temperature of 160 to 180 DEG C to complete the transfer printing. The method does not need conditions such as vacuum, high temperature and high pressure, and the transfer printing can be implemented on the body to be subjected to transfer printing under a low-temperature condition, so that the loss of the basic film is not caused, mass production can be simply realized, and the efficiency of the method is 25 to 35 times of that of a traditional method.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer printing films, and in particular relates to a transfer printing method using thermal sublimation transfer printing films. Background technique [0002] Generally speaking, using the existing transfer film, the transfer is carried out by vacuum adsorption and high temperature (200°C~240°C), or transfer is carried out under high temperature and high pressure. The above-mentioned prior art requires air vacuum, which is cumbersome, and is limited to one transfer film for transfer, so the work efficiency is very low, and the productivity is limited. In addition, equipment and equipment required for air vacuum are required, and the cost is high. When transferring by vacuum adsorption and high temperature, film damage often occurs, the transfer surface is deformed, the concentration and clarity of textures and the like are reduced, and the defect rate is high. .
