Abstract

The invention relates to the technical field of thermal sublimation transfer printing and discloses an instant-dry type thermal sublimation transfer printing PET membrane. The instant-dry type thermal sublimation transfer printing PET membrane sequentially comprises a perforated PET membrane layer, a water absorbing and permeating layer, a porous layer and a surface channel layer from bottom to top; the porous layer is made of interpenetrating network resin formed by cross linking of cellulose, sodium carboxymethyl cellulose or starch and cationic modified polyacrylamide or interpenetrating network resin formed by cross linking of polyacrylamide, cellulose or sodium carboxymethyl cellulose and cationic modified starch; on one hand, the interpenetrating network resin can expand to bear dye and quickly absorb ink; and on the other hand, the composition of the resin is adjusted, and the density of a network is controlled, so that the water permeability is improved, and water molecules can quickly enter the water absorbing and permeating layer. The perforated PET membrane layer has good toughness and mechanical strength, and the size is stable in a printing process, so that the problem of shrinkage of an existing paper base material due to weather is solved. The instant-dry type thermal sublimation transfer printing PET membrane disclosed by the invention has the characteristics of instant dryness after printing, quick ink absorption and good dimension stability; and the demands of quick printing and high-efficiency production are met.

Description

technical field [0001] The invention relates to the technical field of heat sublimation transfer printing, in particular to an instant dry type heat sublimation transfer digital PET film. Background technique [0002] Thermal transfer printing technology refers to printing text, graphics and other content on plain paper or high-precision printing paper with thermal printing ink, and then heating it to 180-230°C within a few minutes by the corresponding thermal transfer equipment A special process in which the colors of images are transferred to different materials realistically. Transfer printing digital paper is the carrier of patterns and inks. It is transferred and printed on different material media by heating to 180-230°C, which basically ensures that all dye molecules are transferred to the media material. [0003] The patent application number is 201420300096.9 fast-drying sublimation transfer printing digital PET film. The digital PET film includes a PET film layer,...
