Embodiment Construction

[0017] The invention discloses a process for preparing imitation parchment paper. The specific implementation of the invention will be further described below in combination with preferred embodiments.

[0018] Described a kind of imitation parchment paper preparation technology, comprises the following steps:

[0019] S1: prepare the raw pulp, the chemical wood pulp composed of softwood pulp with a weight content of 30-45% and hardwood pulp with a weight content of 55-70% is used for pulp preparation, and pulp is formed through beating and pulp preparation;

[0020] S2: Paper making, use the paper machine to make the above pulp. During the paper making process, the pulp is from the headbox to the wire part. The pulp has a high liquid level and a low lip opening. The speed ratio of the pulp to the wire is 1:0.8 , by controlling the pulp-to-net speed ratio, a wet paper sheet with poor uniformity and high and low patchwork pattern flocs is formed; the ratio of the thickness of t...

Abstract

The invention discloses a preparation process of artificial parchment paper, belonging to the technical field of papermaking process. The method comprises the following steps: step 1. preparing primary pulp, blending by using chemical wood pulp containing softwood pulp with the weight content of 30 to 45% and hardwood pulp with the weight content of 55 to 70%, and forming pulp by beating and blending; step 2. manufacturing paper with the pulp; step 3. squeezing and dewatering wet paper sheets, drying and dewatering by using a drier to form body paper; step 4. gluing and coloring the body paper, to be specific, carrying out surface gluing on the body paper by using a surface glue applicator, and adding dye into surface gluing liquid for coloring; and step 5. carrying out press polish and cutting, to be specific, carrying out press polish on the glued and colorized body paper after drying, and cutting into the artificial parchment paper finished products. The preparation method has the beneficial effects that the preparation and addition of the pulp and additives, the manufacturing of paper with the pulp by using the paper machine and the surface gluing are completed at one time in the machine; the pattern composition and the dyeing process are completed in one time in the paper production process; and the obtained colorized artificial parchment paper has good soft paper surface,bright color and strong stereoscopic sensation.

Description

technical field [0001] The invention belongs to the technical field of papermaking technology, and in particular relates to a preparation technology of 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. The imitation parchment is brightly colored, and it is named for its appearance that resembles the pattern of alternating 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 ...
