Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer printing, in particular to a heat sublimation transfer paper with moisture-proof and constant temperature effects. Background Technique

[0002] Heat sublimation printing technology is a printing process based on the sublimation of solid dyes when heated and transferred to the surface of the medium. It is usually used to make personalized products such as clothing, cups, signs, etc. This technology originated in the 1970s and has gradually matured with the progress of material science and manufacturing processes. The core technology of heat sublimation transfer paper lies in its surface coating, which can effectively adsorb dyes and ensure the smooth release of dyes during the heating process. The surface coating of the paper must have excellent heat resistance to avoid damage at high temperatures and ensure the accurate transfer of colors.

[0003] In the prior art, transfer paper is usually made of specific fiber materials to ensure its sufficient heat stability, smoothness and ink absorption, so that during the transfer process, the image can be presented uniformly and clearly. A heat sublimation transfer paper recorded in the patent document with the publication number CN217259258U consists of three parts: a base paper layer, a release layer and a coating layer. The release layer contains 30%-34% by volume of hollow spheres, and the hollow spheres are evenly distributed in the release layer. The hollow spheres in the release layer are composed of materials polymerized from methyl methacrylate and methyl methacrylate components. The processing method is simple and the practicability is high. It can effectively prevent the ink from transferring and penetrating from the coating layer to the base paper layer during printing. The transfer clarity of the pattern is good and the quality of heat transfer printing is high.

[0004] However, when this paper is used, it lacks the moisture-proof effect. In a humid environment, the heat sublimation transfer paper is easy to absorb moisture in the air, resulting in the paper deforming, wrinkling or becoming uneven. This will affect the uniformity of the contact between the print head and the paper, resulting in unclear image transmission or phenomena such as color blocks and blurring.

[0005] Based on this, a heat sublimation transfer paper with moisture-proof and constant temperature effects is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model
