Embodiment 1

[0021] A method for preparing double-sided high-gloss tissue paper, the steps are:

[0022] 1) Pulping: the coniferous wood pulp is disintegrated by a pulper, and then beaten through the knocking pool, the disc mill and the knocking pool in turn, and the deinked waste paper pulp is beaten separately; the beating degree of the above two pulps is 70°SR ; The above two kinds of slurry are blended according to the weight ratio of 1:1, the concentration is adjusted, and a papermaking auxiliary is added; the papermaking auxiliary is composed of the following raw materials in parts by weight: 10 parts of guar gum, quaternary ammonium starch 25 parts, 5 parts of alum, 10 parts of melamine, 50 parts of high-gloss paraffin, the amount of the auxiliary agent is 3% of the weight of the slurry; when guar gum is used as a papermaking auxiliary agent, it can improve the strength of the paper sheet, reduce the formation of gray spots and improve Paper evenness, but its disadvantage is that it...

Abstract

The invention relates to the technical field of papermaking, and provides a preparation method of double-sided high-gloss tissue paper, which solves the problem in the prior art that only one side isof high gloss. The preparation method comprises the following steps: 1) pulping, wherein the beating degree of pulp is 70-75 degrees SR; 2) degritting; and 3) papermaking, namely diluting the mixed pulp subjected to degritting with water, passing through a pressure screen, a head box, a net part, a press part and a drying part, and reeling and slitting to obtain the finished product, wherein the drying part comprises a first drying cylinder, a second drying cylinder, a third drying cylinder, and atomizing nozzles arranged at inlets of the drying cylinders, each drying cylinder is provided witha cylinder surface with high hardness and high smoothness, the atomizing nozzles spray a luster-enhancing remover to each of the drying cylinder surfaces, and carrier rollers are arranged at both sides of the second drying cylinder.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing double-sided high-gloss tissue paper. Background technique [0002] At present, only one side of the tissue paper produced in the market has high gloss, and the gloss of the two sides is quite different. The market needs to provide a double-sided high-gloss tissue paper to improve the quality of the appearance and packaging, and to improve the grade, which is different from Single-sided glossy thin paper used in the market. The preparation method of existing tissue paper is: (1) pulping: according to proportioning, softwood pulp and waste paper deinking pulp are put into the pulper together to disintegrate and mix, then beating together, adjust after beating Concentration, enter the papermaking flow delivery system through the regulating box. (2) Papermaking: The pulping materials are diluted by the flushing tank and evenly dispersed by the head box, ...
