Embodiment 1

[0080] This embodiment provides a light yellow two-color ancient pottery pattern paper, the production method of the light yellow two-color ancient pottery pattern paper includes the following steps:

[0081] (a) Disintegration of pulp: placing pulp boards of softwood pulp and hardwood pulp in a pulper for disintegration;

[0082] (b) beating: the softwood pulp that accounts for 35% of the total pulp ratio and the hardwood pulp that accounts for 65% of the total pulp ratio are mixed and beaten to obtain a pulp that has a degree of knocking of 35 ° SR;

[0083] (c) Dyeing and color fixation: first mix the pulp with the dye for 30 minutes for dyeing, then add 0.1% of the total dry fiber content and mix for 5 minutes to fix the color, and finally add 0.8% of the total dry fiber content Mix PAE wet strength agent for 5 minutes;

[0084]The dye is a mixture of black G accounting for 0.062% of the total dry fiber content, scarlet 4BS accounting for 0.083% of the total dry fiber con...

Abstract

The invention provides a production method of embossed double-color art paper. The production method of the embossed double-color art paper comprises the following steps: (1) dyeing and fixing color:mixing paper pulp, a dye, a color fixing agent and a wet strength agent, and carrying out dyeing and color fixing; (2) drying in a first-stage drying cylinder: forming the dyed and color-fixed paper pulp on a net, squeezing and dehydrating, and drying in the first-stage drying cylinder to obtain a wet paper sheet; (3) embossing: embossing the wet paper sheet obtained by drying in the first-stage drying cylinder in a paper machine; and (4) drying in a second-stage drying cylinder: carrying out second-stage drying cylinder drying on the embossed paper sheet to obtain the embossed double-color art paper. According to the production method of the embossed double-color art paper, the defects existing in traditional off-machine embossing are overcome, and the double-color embossed art paper which can be formed only through alignment embossing after printing forms the artistic effects of color depth change and grain depth change in the paper machine at a time by controlling the dyeing and embossing process of paper sheets in the machine.

Description

technical field [0001] The invention belongs to the field of art paper production, and in particular relates to a method for producing embossed two-color art paper. Background technique [0002] As a major type of art paper, colored embossed paper has always been favored by packaging designers. Art paper is different from other ordinary paper types, such as offset paper, coated paper, light paper, newsprint and packaging paper, etc. Art paper needs special processing equipment and technology to process the paper into a paper page with rich colors and unique textures . Paper dyeing is divided into two types: in-machine dyeing and out-machine dyeing. In-machine dyeing means that dyes are added to the paper machine during paper production, and the paper is dyed into various colors in the paper machine. Out-machine dyeing refers to the first White (non-dyed) sheets are produced from the paper machine, and the sheets are dyed in additional gravure processing equipment or dippin...
