Thermal dye sublimation transfer paper

Abstract

The invention discloses thermal dye sublimation transfer paper. The paper comprises a body paper layer and a coating layer smeared on the body paper layer, wherein the coating layer contains a film forming material and an adsorption material used for adsorbing water-based and oil-based ink, the film forming material is used for receiving thermal dye sublimation ink and release a pigment dye in thethermal dye sublimation ink into a transfer base material, the film forming material is at least prepared from polyacrylamide, and the adsorption material is prepared from an inorganic filler, modified starch and silicate mineral substances. The thermal dye sublimation transfer paper not only can receive water-based thermal dye sublimation transfer ink to print, but also can adapt to oil-based thermal dye sublimation ink printing, widens the application range of the transfer paper, and solves the problem that permeation in water-based thermal dye sublimation ink is large, the transfer rate islow, white spots in the oil-based thermal dye sublimation ink are more, and the precision is low.

Description

technical field [0001] The invention relates to the field of thermal sublimation transfer printing, in particular to a thermal sublimation transfer paper suitable for use in water-based and oily thermal sublimation inks. Background technique [0002] Sublimation transfer printing is a new technology that prints or prints digital images on sublimation transfer printing, and transfers ink pigments and dyes to textiles through temperature and pressure. With the advancement of environmental protection and technology, its application fields are becoming wider and wider. [0003] At present, the thermal sublimation transfer paper prepared with sodium carboxymethyl cellulose as the main film-forming material is widely used in water-based thermal sublimation ink, such as the early The invention patent CN1315906A (invention name: transfer paper for inkjet printing) applied for in 1999 provides a kind of one or more of sodium carboxymethyl cellulose, modified starch, biological latex...

AI Technical Summary

Problems solved by technology

With the advancement of technology, in recent years, the demand for sublimation transfer paper in the digital printing market has maintained rapid growth, especially in recent years, the sublimation transfer paper used for water-based Great technological progress has been made in terms of efficiency and color reproduction, but limited by the drying of the ink and the printing accuracy of the equipment, there are still problems such as slow printing speed, low production efficiency, and uneven color reproduction under different ink matching. Phenomenon

[0004] The traditional printing technology, such as the sublimation transfer printing technology based on gravure mimeograph, uses oily sublimation transfer printing ink, which has fast production speed and low raw material cost, and is widely used in textile printing and other industries, but it also has its limitations. characteristics, such as single plate making and low precision

[0005] It can be seen that if you take the transfer paper suitable for water-based dye-sublimation ink for oil-based dye-sublimation ink printing, or take the transfer paper suitable for oil-based dye-sublimation ink for water-based dye-sublimation ink printing, there are many white spots, poor precision, and transfer printing. Low efficiency, slow drying and other technical problems
