Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to a thermal sublimation transfer film. Background technique [0002] Dye-sublimation transfer printing is a waterless printing and dyeing process with high environmental protection effect. It is of great value to the energy-saving and emission-reduction renovation projects of high-energy-consuming industries advocated by the state, and has become a research hotspot. The principle of sublimation transfer printing is that at high temperature (usually above 220°C), the disperse dye on the sublimation transfer medium is sublimated to the chemical fiber fabric and fixed directly by the fabric fiber. The printed and dyed chemical fiber fabric can be washed without water. It can be considered that the dye-sublimation transfer printing process, especially the digital dye-sublimation transfer printing process, is a highly environmentally friendly, practical and...

Problems solved by technology

[0003] Since the existing sublimation transfer film has the problem of PET flake melting under high temperature, it is also necessary to protect the particularity of the transferred film made of various physical properties from damage, deformation and damage, and perform instant thermal transfer , the printing effect is unstable under strong adhesion. Using the existing thermal transfer film, it is impossible to apply thermal transfer printing products on the transferee with different physical properties and special characteristics. Using the existing thermal transfer film The film must be transferred to the object to be transferred with the help of high temperature and high pressure, and the problems of damage, deformation and breakage of the printed surface cannot be avoided
