Abstract

The invention relates to the technical field of sublimation transfer printing and discloses instant dry type sublimation transfer digital paper. The instant dry type sublimation transfer digital paper comprises perforated PP paper, a water absorbing and permeable layer, a porous layer and a surface channel layer which are sequentially arranged from bottom to top; the porous layer is made of interpenetrating network resin formed by crosslinking of cellulose or sodium carboxymethylcellulose or starch and modified cationic polyacrylamide, or formed by crosslinking of polyacrylamide or cellulose or sodium carboxymethylcellulose and modified cationic starch; on one hand, the interpenetrating network resin can swell to 'catch' a dye for quick ink absorption, and on the other hand, components of the resin are adjusted and the network density is controlled to improve the water permeability, so that water molecules can quickly enter the water absorbing and permeable layer; and the perforated PP paper has excellent flexibility and mechanical strength and is stable in size in the printing process, so that the problem of shrinkage, caused by weather, of the conventional paper base material is solved. The instant dry type sublimation transfer digital PP paper has the characteristics of being instant in drying, quick in ink absorption, good in size stability and low in cost, and can meet the requirements for quick printing and efficient manufacturing at present.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to an instant-dry digital PP paper for thermal sublimation transfer printing. 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 201420300349.2 for fast-drying sublimation transfer digital PP paper. The digital PP paper includes a PP pap...
