Introduction to adhesive thermal sublimation transfer paper

The adhesive thermal sublimation transfer paper includes a base paper, the surface of which is coated with a coating, the coating components include 7-18 parts of sucrose, 2-8 parts of pentaerythritol, 2-10 parts of starch, 10-20 parts of cellulose, 1-5 parts of fumed silica, 5-15 parts of polyethylene glycol fatty acid ester, 1-6 parts of acrylic leveling agent, 5-15 parts of polyvinyl chloride resin, 3-8 parts of inkjet medium adsorbent, 4-10 parts of zircon powder and 10-20 parts of inorganic nano zirconium oxide. The preparation process of the invention is simple, the obtained transfer paper has high viscosity and low shrinkage rate, and will not deform after absorbing ink, thereby ensuring the transfer quality. Sublimation transfer paper is generally used for printing fabrics or materials containing polyester. The ink made of disperse dyes is used to print the pattern on the inkjet sublimation transfer paper through an inkjet printer. Then the printing surface and the transfer surface are attached and heated to 170-230℃. The dye in the ink is heated and sublimated into the transfer object to achieve the transfer printing of the image.

The emergence of sublimation transfer paper not only improves the printing sophistication, but more importantly, it conveniently realizes the waterless printing and dyeing of textiles. Under the control of a computer, the inkjet printer can directly print colorful and realistic effects on the inkjet sublimation transfer paper without the need for plate making and other processes. After a simple heating process, the transfer object can obtain a delicate printing effect. The existing sublimation transfer paper is complicated to prepare, and the obtained transfer paper has a high shrinkage rate, a low transfer rate, and poor transfer quality.
