A kind of manufacturing method of quick-drying sublimation paper

Abstract

The invention discloses a method for producing quick-drying thermal sublimation paper, which relates to the field of production of a thermal sublimation transfer paper, and can solve the contradiction of the transfer rate of the transfer paper and the drying speed, and can accelerate the drying speed. The method comprises the following steps: selecting the raw paper having strong water resistance, and coating a thermal sublimation transfer paper ink holdout coating layer on right side of the raw paper; and then coating the back side of the raw paper with the coating layer which is benefit for increasing water-absorbing quality, wherein a rubber compound of the coating layer comprises combination of water and an interface activator, or combination of water, starch and the interface activator, the mass percentage of the interface activator is 0.5-5%, and the mass percentage of the starch is 0.5-3%.

Description

technical field [0001] The invention belongs to the field of manufacturing thermal sublimation transfer paper, in particular to a method for manufacturing fast-drying thermal sublimation paper. Background technique [0002] Sublimation transfer printing is to print portraits, landscapes, text and other graphics and texts on inkjet paper for sublimation transfer printing in a mirror image using an inkjet printer equipped with sublimation transfer ink, and then heat them to At about 200°C, the thermal transfer ink on the sublimation paper sublimates and penetrates into the substrate, so that the color image on the paper can be vividly transferred to a material such as textiles, porcelain cups, porcelain plates, porcelain plates, and metals. A new technique. Dye-sublimation transfer graphics are bright and rich in color, and its effect is comparable to that of printing. [0003] Initially, the consumable sublimation transfer paper used in thermal transfer sublimation technolo...

Problems solved by technology

The water absorption capacity of the base paper is related to the sizing strength. If the sizing of the base paper is too poor (that is, the water absorption is too strong), it is easy to cause too much migration of the thermal sublimation coating into the paper during coating, thereby reducing the barrier of the coating. The ability of sublimation ink causes the dye molecules in the ink to migrate to the base paper layer. Although the defect can be compensated by increasing the thickness of the coating, the coating is too thick, which will cause curling problems and inconvenience in use, thus affecting the application performance of the product.

In order to increase the drying speed of sublimation transfer paper, some manufacturers start with the coating and increase the proportion of water-absorbing materials in the coating, such as silica, alumina, etc., so as to improve the water-absorbing capacity of the coating, but these materials At the same time, it will absorb water and sublimate the dye molecules, which will make it difficult for the dye molecules to sublimate to the textile during the thermal transfer process, resulting in a decrease in the transfer rate and affecting the performance of the product.
