Problems solved by technology

[0005] When printing on a multi-nozzle printer, the ink drying ability of the transfer paper is severely challenged. If the drying ability is insufficient, it is necessary to add a high-power oven lamp for heating and drying.
And the high-power baking lamp makes the digital technology lose the feature of energy saving

Abstract

The invention provides uncoated digital ink jet transfer printing base paper and a production method thereof. The uncoated digital ink jet transfer printing base paper comprises plant fiber and an inorganic filler, wherein an impregnation treatment agent is filled between the plant fiber and the inorganic filler. The invention also discloses the preparation method of the uncoated ink jet transferprinting base paper, and the preparation method comprises the following steps: base paper is prepared by pulping, blending pulp, forming, squeezing and drying; the base paper is further subjected to impregnation treatment; an impregnation liquid penetrates into the base paper and wraps the surfaces of the plant fiber and the inorganic filler on the surface layer of the base paper; and the uncoatedink jet transfer printing base paper can be obtained after subsequent drying and calendering. The uncoated digital ink jet transfer printing base paper has the advantages that the paper surface is flat without warping, ink on the paper surface is easy to dry, the gloss of the ink is not reduced, and the transfer printing is uniform.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a transfer printing base paper and a production method thereof. Background technique [0002] Transfer printing is one of the more popular printing methods today. Its advantages are artistic patterns, fine outlines, clear layers, lifelike shapes, relatively simple processing, and no pollution, less investment, energy saving, and small equipment footprints. Transfer printing is to print the dye on the transfer printing paper first, and then transfer the dye from the transfer printing paper to the textile through heat treatment, so as to form the desired pattern on the textile. [0003] The preparation of digital inkjet sublimation transfer paper is generally to coat a layer of ink-absorbing ink layer or barrier layer on the base paper. On the one hand, it can absorb ink, and on the other hand, it can prevent the disperse dyes in the ink from penetrating In the paper fiber, it...
