High-quality sublimation transfer printing paper and production process thereof

Abstract

The invention relates to the field of pulping and papermaking, in particular to high-quality sublimation transfer printing paper and a production process thereof. According to the process, plant fiberand vinylon instead of traditional singular plant fiber are adopted as fiber raw materials for papermaking, wherein two types of vinylon are selected and used in a combined mode, one type is easily dissoluble, and the other type is insoluble; the easily dissoluble vinylon in the body paper obtained through the mode can be dissolved in the process, and a continuous film layer is formed among the fiber after dissolution is performed, so that the strength of the paper is increased on the one hand, and the water resistance of the paper is improved on the other hand; in the later printing process,ink does not easily penetrate into the paper, so that the transfer rate is improved; the insoluble type vinylon has the effects that the characteristics of poor elasticity, large hardness, high strength and stiffness of the insoluble type vinylon are utilized so that the shortness of poor stiffness of low-gram weight paper is overcome, and the characteristic of difficult dyeing of the insoluble type vinylon is utilized, so that adsorption of the ink during printing is reduced, and the transfer rate of the ink is also improved.

Description

technical field [0001] The invention relates to the field of papermaking, and relates to a high-quality thermal sublimation transfer printing paper and a production process thereof. Background technique [0002] Sublimation transfer printing is to print portraits, landscapes, text and other graphics and texts on the sublimation transfer paper in a mirror image using an inkjet printer equipped with sublimation transfer ink, and then heat it to about 200°C through the thermal transfer printing equipment , so that the sublimation ink on the sublimation paper penetrates into the substrate, and the quality of the sublimation transfer paper directly affects the result of the above process. [0003] Now the production of sublimation transfer printing paper is generally divided into two steps. The first step is to copy the base paper for sublimation transfer printing in the paper machine. The base paper has surface sizing or no sizing; the second step is to make the base paper two ...

Problems solved by technology

[0004] Aiming at many problems existing in the prior art, the present invention provides a high-quality sublimation transfer printing paper and its production process. The process uses plant fiber + vinylon instead of the traditional single plant fiber as the fiber raw material for paper, wherein Vinylon Two types of fiber are used in combination, one is easy-soluble type (dissolution temperature 45-60°C), and the other is insoluble type (dissolution temperature ≥ 80°C). The base paper obtained in this way is easily soluble Type Vinylon can be dissolved in the process, and after dissolution, a relatively continuous film is formed between the fibers. On the one hand, it increases the strength of the paper, and on the other hand, it can improve the water resistance of the paper. In the later printing process, the ink is not easy to penetrate. Into the paper, improve the transfer rate; the effect of the insoluble type, one is to use its poor elasticity, hardness and strength and rigidity to improve the shortcomings of low stiffness paper; the other is to use its not easy The characteristics of dyeing reduce the adsorption of ink during printing, and can also improve the ink transfer rate
