Coating of transfer paper and preparation method thereof

Abstract

The invention provides a coating of transfer paper. The coating comprises the following components in parts by weight: 0.5-50 parts of modified polyvinyl alcohol, 0.02-20 parts of a cross-linking agent, 5.0-99.3 parts of water-soluble polysaccharide, 0.1-90 parts of a drying agent and 0.1-2 parts of a defoaming agent, wherein the coating of transfer paper is obtained through a cross-linking reaction, and the modified polyvinyl alcohol is at least one selected from a group consisting of itaconic acid modified polyvinyl alcohol, maleic acid modified polyvinyl alcohol, acetoacetyl modified polyvinyl alcohol, carboxyl modified polyvinyl alcohol and diacetone modified polyvinyl alcohol. The coating of the transfer paper forms a macromolecular reticular structure, so the integrity of the coatingcan be ensured during printing with the maximum ink amount, image cracking is prevented, and reduction in definition caused by migration and diffusion of ink to the periphery is prevented; and moreover, the coating of the transfer paper has the capacity of resisting ink to migrate and permeate into the paper, more effective components of the ink can be accumulated on the surface of the coating, and the transfer rate of the ink is increased.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a transfer paper coating and a preparation method thereof. Background technique [0002] Dye-sublimation transfer paper is used for printing of polyester fabrics. The processing procedure is simple, it can meet personalized customization, and it will not cause water pollution. The growth rate in recent years has exceeded 30%. More and more coating companies Joining the sublimation transfer paper supply line, the production capacity has been further expanded, the competition is fierce, and high-quality and stable products have gradually become the core competitiveness of this industry. [0003] In the process of sublimation transfer paper processing, the performance of transfer paper products is mainly affected by the performance of the ink-loading coating, but the existing ink-loading layer has insufficient ink loading, insufficient ink locking ability, insufficient transfer ...

AI Technical Summary

Problems solved by technology

[0003] In the processing of sublimation transfer paper, the performance of the transfer paper product is mainly affected by the performance of the ink-carrying coating, but the existing ink-carrying layer has insufficient ink capacity, insufficient ink locking ability, insufficient transfer ability, and easy coating. Cracks will cause obvious deviations between the transfer image and the target image, resulting in quality problems in the final product
