Problems solved by technology

This method is produced by making base paper inside the machine, and then coating dyes outside the machine. The disadvantages of this method are that there are many production processes, complicated operations, complex coating formulas, high cost, and difficult precise control of paper color. Discoloration, poor three-dimensional effect

Embodiment 1

[0027] Embodiment 1: background color is white, pattern is the production method of the light green imitation parchment paper of light green, and its concrete steps are as follows:

[0028](1) Equipped with 20-40% coniferous pulp, 60-80% broad-leaved pulp, 40-45°SR percussion degree, and 2.0-5.0g wet weight. 0.04% VBL brightener in pulp, 1.5% cationic starch, 1.0% AKD, 18% filler, 120ppm cationic amide. In order to make a very obvious difference between the base color and the pattern color, add a brightener to the base color paste in the process setting.

[0029] (2) Papermaking by paper machine The above-mentioned prepared pulp is used for papermaking, and the wet paper sheet with poor uniformity is formed by controlling the pulp-net speed ratio; the wet paper sheet has high and low patchwork flocs ; The web table does not use shaking and facing rollers to form a wet paper sheet with uneven pulp layers and uniform flocculation.

Abstract

The invention relates to a production method of color imitation parchment paper, comprising the following steps of: carrying out paper making on a prepared slurry by using a paper machine, controlling the jet / wire speed ratio to form a well-proportioned pattern floc aggregate-carrying wet paper sheet with poor uniformity; finishing the paper surface by a pressure roller before applying glue onto the surface, planishing several tiny convex portions on the paper surface to form a paper sheet containing different bulk densities of pattern floc aggregates; applying glue onto the surface of the above paper sheet by a surface sizing applicator to form a sized paper sheet with a dense-dilute color pattern, wherein dyes are added in a surface sizing solution; drying to form a paper sheet with strong stereoscopic impression, and slitting to obtain the finished product color imitation parchment paper. According to the invention, the technological flow is simple, the production technology is stable and reliable, and the produced parchment paper has very strong stereoscopic impression and artistic effects. The paper surface has good soft texture, brilliant color, and strong sheepskin visual effect.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production method of colored imitation parchment paper. Background technique [0002] As we all know, parchment is an expensive writing material made of parchment or calfskin treated with lime, then sheared off, and softened. Most of the important legal documents or precious texts in ancient Europe were made of parchment, which has been handed down to future generations. sheepskin books. Parchment was used from the 2nd century BC until it was replaced by paper in China after the 14th century. [0003] The colored imitation parchment is brightly colored, and it is named for its appearance that resembles the pattern of shades and shades of ancient parchment. The paper is firm and suitable for printing, and because of its unique appearance pattern similar to ancient parchment, it is endowed with a special charm and beauty of historical and cultural accumulation. It is a typi...
