Thermal dye sublimation transfer paper

Abstract

The invention discloses thermal dye sublimation transfer paper which comprises an ink holdout layer, a paper fiber bonding layer, a base paper layer and a back coating. The ink holdout layer comprises polyanionic cellulose and dry filler. The paper fiber bonding layer adopts a binder, namely water-base resin. The coating comprises 1-10 parts of saccharose, 1-15 parts of pentaerythritol, 1-10 parts of starch, 2-15 parts of cellulose, 2-10 parts of fumed silica, 2-16 parts of polyvinyl alcohol, 2-18 parts of glycerinum, 2-9 parts of barium sulfate, 2-15 parts of hydroxymethyl cellulose, 1-10 parts of a sterilizing agent, 2-15 parts of organic solvent, 2-15 parts of a surface active agent, 1-10 parts of a non-polar oxide, 1-15 parts of a thickening agent, 1-10 parts of a neutralizer, 2-15 parts of tall oil fatty acid, 1-15 parts of polyacrylamide, 1-10 parts of a polysaccharide derivative, 1-15 parts of a corrosion inhibitor, and 1-10 parts of a printing ink medium adsorbent. The preparation technique is simple, and obtained printing ink has great ink holdout capacity, corrosion resistance, abrasion resistance, oxidation resistance, water resistance and adhesive capacity.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a sublimation transfer paper. 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 reliable process that is expected to rep...

Problems solved by technology

However, since the sublimation transfer printing process needs to be heated to a higher temperature, the ink binder must have a certain heat resistance during high-temperature transfer. In addition, the ink holding capacity of the existing transfer paper ink is relatively poor, and it needs to be coated The amount is relatively large, and there are few domestic and foreign dye-sublimation transfer printing papers and their preparation methods
