Method for producing marble art paper

Abstract

The invention relates to a method for producing marble art paper, comprising the following steps: selecting 20% of softwood pulp and 80% of bleached eucalyptus pulp, controlling the beating degree of the pulps within 34-35 DEG SR, the screening concentration of the pulps at 0.9-1.0%, the quantification of paper at 95 g / m<2>. And the surface absorption weight at 20-30 g / m<2>; and dyeing the paper twice, wherein during the first dyeing, a dye is added to a paper machine flow which is conveyed to a high tank, and the liquid dye is directly added to the high tank to be mixed with the pulps, and during the second dyeing, at an initial phase of dehydration and screening of the pulp flow, the dye is sprayed onto a paper machine screen part through a spraying device, and natural and soft simulated cloud patterns or marble patterns are formed through shaking the paper machine screen part and naturally dispersing the dye so as to obtain the marble art paper. The marble art paper has the advantages of easiness in production, reliable production process, high operability, soft paper surface color, abundant colors and cloud pattern effects. The marble art paper is mainly applied to package of special products, book cover, high-order offices and the like.

Description

technical field [0001] The invention relates to a production process of art paper, in particular to a production method of marble 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 used is...
