Problems solved by technology

[0002] At present, the sublimation transfer paper commonly used in the market is usually composed of base paper and coating. A complete sublimation transfer paper needs to go through the process of base paper processing and coating. The production process is complicated and cumbersome. Compared with traditional use, it is expensive High cost for sublimation coating based on molecular materials
Common microporous coatings are usually mixed with porous materials and high-molecular polymers, and the high-molecular materials absorb water and swell, which is easy to block the pore structure of the porous material, resulting in the situation that the porous material cannot perform its performance, resulting in an unsatisfactory transfer rate. expected
