Production method of digital inkjet heat transfer printing base paper

Abstract

A production method of digital inkjet heat transfer printing base paper comprises the following steps: 1, mixing and pulping 10-40% of bleached softwood pulp and 60-90% of bleached hardwood pulp; 2, adding a pulp filler, a degassing agent, a wet strength agent, pulp glue and AKD into the pulp; 3, performing net papermaking on paper pulp, and squeezing to form a paper sheet; 4, predrying the papersheet dewatered by squeezing through a large-diameter drying cylinder of a paper machine; 5, gluing the surface of the paper sheet with surface glue; 6, gluing and drying the paper sheet through a first small-diameter drying cylinder assembly of the paper machine; 7, coating the surface of the paper sheet with coating; 8, coating and drying the surface of the paper sheet with a drying oven; 9, postdrying the paper sheet through a second small-diameter drying cylinder assembly of the paper machine. The digital inkjet heat transfer printing base paper produced by the production method of the digital inkjet heat transfer printing base paper has relatively low transverse expansion and contraction rate, and the distortion of a jetted pattern during heat transfer printing is relatively small.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for producing digital inkjet thermal transfer base paper. Background technique [0002] Digital inkjet thermal transfer printing is one of the transfer printing methods; when transferring, the pattern is first spray-painted on the digital inkjet thermal transfer base paper, and then the pattern is transferred to the product by heat pressing. The traditional production method of digital inkjet thermal transfer base paper has the disadvantages that the produced digital inkjet thermal transfer base paper has a large lateral expansion rate (≥2.5%), and the pattern distortion and deformation of the inkjet printing during thermal transfer are relatively large; therefore, it is necessary to design a The production method of the digital inkjet thermal transfer base paper produced has a small lateral expansion rate, and the digital inkjet thermal transfer base paper production method w...
