preparation example Construction

[0017] (3) The preparation of fiber pulp uses coniferous wood pulp as raw material, puts the coniferous wood pulp board into a hydraulic pulper, the crushing concentration is 4-5%, and the crushing time is 15-20 minutes. Under the action of water conservancy and machinery Disintegrate the paddle into white fiber slurry, in which the length of a single fiber is 2-4mm, and the width is 40-60μm. After the disintegration is completed, put it into the storage tank, add water to adjust to the use concentration, and the use concentration is 1.2%. Reserve; the coniferous wood pulp is Stone brand coniferous wood pulp produced in the United States.

[0018] (4) Slurry mixing In the process of dyeing basic slurry flow, mix the prepared white fiber slurry and dyeing basic slurry. The white fiber slurry is added in the flow pipeline before the pressure screen of the paper machine , the adding method is to mix evenly with the dyed basic slurry in the pipeline along the flow, and the additio...

Abstract

The invention relates to a production method for fiber color art paper, which comprises the following steps: preparing and dyeing basic slurry, preparing fiber slurry and mixing the slurry, wherein the step of dyeing the basic slurry is completed by adding dyes into a dosing jar so as to form deep-color basic slurry in single color; during a drifting process of the dyed basic slurry, mixing the prepared fiber slurry with the dyed basic slurry, wherein the fiber slurry is added into a drifting pipeline in front of a pressure screen of a paper machine; after mixing the dyed basic slurry with white fiber slurry, adding dispersing agents; making paper with pulp on a paper machine; and after putting onto a net and dewatering, shaping, drying and reeling, forming the fiber color art paper with excellent natural texture and with white fibers distributed in deep-color backing paper. The fiber color art paper has the advantages that the processing and manufacturing are easy, the production technology is reliable, the operability is strong, the fiber bonding strength is excellent, the color is rich and various and the paper surface has natural textures. The fiber color art paper is mainly applied to the packaging of special products, various certificates, book covers, restaurant menus, wine lists, and the like.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production method of fiber colored art paper. Background technique [0002] We know that with the development of the packaging and printing industry, the demand for special paper in the domestic market is increasing. Special paper has become a family of paper products that cannot be underestimated. There are more and more varieties, and the scope of application is also expanding. Among them, fiber art paper is a typical representative of special paper, which is mainly used for exquisite book covers, title pages, invitation cards, greeting cards, high-end packaging paper, etc. Fiber art paper produced by traditional methods is generally made by adding polyester fibers with properties completely different from plant fibers in the batching pool, and then dyeing and copying through the process. Although the production process of this method is simple, because the polyester fib...
