Instant-drying type high-ink-absorption heat sublimation transfer printing digital paper

Abstract

The present invention relates to the technical field of heat sublimation transfer printing, and discloses instant-drying type high-ink-absorption heat sublimation transfer printing digital paper, which sequentially comprises base paper, a water absorption and water permeation layer, a porous mesh bag layer and a surface channel layer from bottom to top, wherein the porous mesh bag layer is a three-dimensional mesh-bag-like interpenetrating network resin formed by cross-linking cellulose or carboxymethyl cellulose sodium or starch and cation modified polyacrylamide, or a three-dimensional mesh-bag-like interpenetrating network resin formed by cross-linking polyacrylamide or cellulose or carboxymethyl cellulose sodium and cation modified starch so as to significantly increase the ink absorption. According to the present invention, the water permeability is increased by regulating the composition of the resin and controlling the network density, such that the water molecules rapidly enter the water absorption and water permeation layer; and the instant-drying type high-ink-absorption heat sublimation transfer printing digital paper has characteristics of high ink absorption capacity, rapid ink absorption, instant drying after printing, good transfer printing effect and the like, and meets the fast printing and efficient production requirements of various dark fabrics.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to an instant dry digital paper with high ink absorption capacity 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 201310320140.2 high ink absorption thermal sublimation transfer digital paper, th...

However, the hydrophobic layer in this patent effectively prevents the direct combination of dye molecules with the substrate paper, and also affects the rapid volatilization and drying of water molecules through the paper substrate, which can only meet the printing requirements of 15-30 meters per hour. In addition, the patent uses two The interpenetrating network resin formed by isocyanate cross-linking is mainly a two-dimensional network structure. Although it can increase the ink absorption to a certain extent, it cannot meet the development needs of various dark complex patterns.

[0004] In recent years, in order to improve the production efficiency of digital printing production, the design and improvement technology of printers has developed rapidly. The technology of printers has made remarkable progress from single nozzles, double nozzles to multi-nozzles. The production speed of printers has also increased from the original 15 to 30 meters per hour. 100-2000 m / h, the production speed of digital printing is gradually approaching that of traditional printing and dyeing. For the production of various dark complex patterns, the ink absorption capacity and drying speed of digital transfer paper produced by current technology can no longer meet the needs of fast printing. New technologies and methods are needed to solve the existing problems in production
