The upper surface of the surface channel layer 5... The surface is fixedly connected to the anti-stick isolation layer 6, and the upper surface of the anti-stick isolation layer 6 is fixedly connected to the special coating layer 7. The outer surface of the hollow fiber layer 4 is provided with microporous channels 8, and there are multiple microporous channels 8. The microporous channels 8 are hexagonal.

[0027] Working principle: When using thermal sublimation transfer paper, the surface channel layer 5, in conjunction with the microporous channels 8 on the hollow fiber layer 4, increases the contact area between the dye and hot air, thereby improving the sublimation rate and uniformity of the dye. The dehydration layer 2 removes moisture, preventing it from affecting the transfer effect. The absorbent and permeable layer 3 quickly absorbs and transfers moisture, thus increasing the drying speed of the transfer paper. The anti-sticking isolation layer 6 prevents dye molecules from directly binding to the substrate paper and reduces the permeability of water molecules, thereby increasing the drying speed of the transfer paper. The special coating layer 7 significantly increases the transfer speed of the transfer paper on the hot roller, thereby improving production efficiency.
