Embodiment Construction

[0015] The invention discloses a method for preparing art paper. The specific implementation of the invention will be further described below in combination with preferred embodiments.

[0016] Described a kind of method for preparing art paper, comprises the following steps:

[0017] S1: raw material preparation, select 25% coniferous pulp and 75% hardwood pulp for beating;

[0018] S2: defoaming, the above slurry produces a lot of air bubbles during stirring and mixing, and the air bubbles are eliminated by vacuuming;

[0019] S3: Carry out primary dyeing, where the dyestuff of the primary dyeing is added to the head box of the paper machine flow, and the liquid dye is directly added into the head box to mix with the slurry, and the slurry forms a single background color;

[0020] S4: Carry out secondary dyeing. The secondary dyeing is at the initial stage of dehydration of the slurry flow on the net. The dye is sprayed on the wire part of the paper machine through the spra...

Abstract

The invention discloses a method for preparing art paper, and belongs to the technical field of paper making. The method comprises the following steps of S1, raw material preparation, wherein 25% of softwood pulp and 75% of hardwood pulp are selected for mixed pulping; S2, defoaming, wherein a large number of bubbles are generated when the pulp is stirred and mixed, and bubbles are eliminated through vacuumizing; S3, one-time dyeing; S4, second-time dyeing; S5, art paper forming, wherein due to rocking vibration of a paper machine net part and natural dispersion of dye, natural and soft colorlines are formed on the paper, then, molding drying is performed, a finished product is rolled, and the art paper is obtained. The method has the advantages that machining and manufacturing are easy,the production technology is reliable, operability is high, the paper surface has soft color, and the abundant color texture and cloud line or marble line effects can be achieved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a method for preparing art paper. Background technique [0002] We know that papermaking technology is usually made of fiber raw materials through beating, batching, and papermaking. The performance of paper depends on the type and use of paper. Different types of paper have different raw material configurations, manufacturing methods, and process technologies. At present, there are hundreds of paper varieties, and only packaging paper accounts for 37% of the total packaging materials. Paper has steadily developed from information paper to packaging paper and other industries, varieties, and purposes. At present, most of the domestic packaging and decoration papers are made of cardboard or coated cardboard, boxboard, etc., which are of low grade and poor quality, and do not have anti-counterfeiting performance and artistic performance. The papermaking technology u...
