If the printing quality is poor, the effect of the transfer product will be worse, which is mainly manifested in poor coloring quality of the substrate, uneven color, inconsistent depth, etc. Various defects on the image will be more obvious after transfer, affecting product quality
In addition, if the coating cannot quickly absorb ink, the phenomenon of ink accumulation is serious. In the continuous production process, it is easy to cause ink rubbing, resulting in damage to the printed image and defective products, which will affect the transfer yield and continuous production efficiency.

Abstract
The invention discloses heat sublimation digital transfer paper and a production method. The heat sublimation digital transfer paper comprises base paper, at least a receiving layer and at least a back coating layer; and the heat sublimation digital transfer paper is characterized in that the base paper is manufactured by 100% of wood pulp; the receiving layer is composed of 30%-70% by weight of a white pigment and 30%-70% by weight of an adhesive, the solid content of the receiving layer is 10%-50%, the viscosity is 400cps-1800cps, and the coating weight of the receiving layer is 1g / m<2>-20g / m<2>; and the back coating layer is composed of natural glue or synthetic glue, the solid content of the back coating layer is 2-10%, the viscosity is 5-200cp,and the coating weight is 0.5-2g / m<2>; and the production method comprises the following steps: a, producing the base paper: producing the base paper by the wood pulp on a fourdrinier, wherein surface sizing of the base paper is membrane transfer sizing; and b, performing coating on the receiving layer and the back coating layer, wherein coating of the receiving layer and the back coating layer is finished on a coating machine.
Description
technical field [0001] The invention relates to a thermal sublimation digital transfer paper and a production method, belonging to the technical field of composite paper production. Background technique [0002] Sublimation transfer printing substrates must be polyester fibers or products with polyester fibers or similar polyester fiber materials on the surface. The transfer principle is the presence of amorphous regions of polyester fibers When the temperature rises to about 200°C, the amorphous zone moves violently, the voids increase and gradually form a semi-molten state, that is, the so-called "liquid layer" is formed, which creates conditions for the gaseous disperse dye to enter the fiber. At this temperature, the dye is sublimated into a gaseous state. Due to the attraction of the dye sublimation force, the gaseous dye moves around the polyester fiber, and then diffuses into the amorphous area. In the shaping area, achieve the coloring effect. Only polyester fibe...
