Production method of art paper containing crude fibers

Abstract

The invention relates to a production method of art paper containing crude fibers, which comprises the steps: preparing slurry, manufacturing by a paper machine, drying before sizing, sizing on a surface, drying after sizing, slitting, packaging and the like. Commercial bleached sulfate chemical wood pulp and sisal yarn are selected as raw materials; the raw materials comprises the following components in percentage by weight: 50-70% of softwood pulp boards, 10-30% of sisal yarns and 20-30% of hardwood pulp boards; beating processing is carried out by a beater; the beating degree of the slurry is 35-36 degrees SR; the wet weight is 4-5g; a polyvinyl alcohol aqueous solution is used as sizing liquid for surface sizing; and the concentration of polyvinyl alcohol is 5-6%, and the temperature of the surface sizing liquid is 55-60 DEG C. The production method provided by the invention is easy to implement and simple in formula of the surface sizing liquid; the surface of the obtained paper product is rough; the crude fibers protrude on the paper surface; and the processed paper is high in bulk, high in strength, high in stiffness and good in natural texture of coming back to earth.

Description

technical field

[0001] The invention relates to the technical field of papermaking, in particular to a method for producing art paper containing coarse fibers. Background technique

[0002] We know that the surface of traditional packaging paper is smooth and bright, and the printing gloss is good. For example, from coated paper packaging to coated white cardboard, glass cardboard, aluminum foil gold and silver cardboard packaging, and then to PET mirror composite cardboard packaging. The features all reflect the luxurious and bright features of the packaging.

[0003] With the continuous change of people's aesthetic views and visual perception, and the constant attention to environmental protection, safety and hygiene, the taste and grade of packaging paper are also required to be continuously improved. Not only is the paper required to have the characteristics of a smooth and uniform surface in the past, but also a paper with a rough surface, protruding from the surface o...

Embodiment 1

[0030] Embodiment 1: the production method of the art paper (earth paper) that beige contains coarse fiber, its concrete steps are as follows:

[0031] (1) Equipped with pulp The ratio of raw materials is 60% of Canadian Kelly softwood pulp, 20% of Rizhao Senbo hardwood pulp, and 20% of Guangxi sisal silk. First, the sisal silk is cut into short fibers with a diameter of 100-400um and a length of 2-4mm. Add coniferous wood pulp and hardwood pulp to the hydraulic pulper according to the above ratio for pulping treatment, and disintegrate the finished pulp board into single fibers, and add sisal fiber filaments into the pulper at the same time to make it Mix thoroughly with pulp fibers. The mixed pulp is beaten slowly with a light knife through the beater. The beating concentration is 5.0%, the beating current is 120A, the beating pressure is 0.18MPa, the beating time is 2 hours / ton of pulp, and the final beating degree is 35- 36 0 SR, wet weight 4-5g. The pulp processed by ...
