Problems solved by technology

[0002] Coated base paper is the base paper for the production of high-gloss digital photographic paper. It is processed by plant fibers. The produced base paper is generally pulped, beaten, mixed, formed on the Internet, surface sizing, and dried to make base paper. , most of them are produced with pure wood pulp, the paper produced in this way has poor stiffness and poor absorbency, and causes a waste of wood resources; the photo paper made of base paper after primer and top coating has a soft hand feel, and the printed picture is gray. The ink absorption speed is slow, the saturation is not enough, resulting in general color reproduction, easy deformation of paper and other shortcomings, which cannot meet the printing requirements of high gloss, high waterproof, high ink absorption, and fast drying

Abstract

The invention discloses a production process of digital photo paper synthesized by multiple fibers. The production process comprises the following procedures: internal sizing liquid preparing, surface sizing liquid preparing, pulp breaking, pulp mixing, net forming, surface sizing, drying and reeling, blending, prime coating and cast coating, wherein in the pulp breaking procedure, bamboo pulp and reed pulp are added to the original wood pulp and sodium silicate is added to the breaking solution; in the surface sizing procedure, the surface sizing liquid is prepared by decocting modified starch and cassava starch and a rheology modifier is added; in the blending procedure, the membrane ultrafiltration deionized water is used; and in the prime coating procedure, a soft calender and four dryers are added. The produced high gloss photo paper has a fine and smooth surface and the characteristics of high gloss and density, wide color gamut, high ink absorbency and water resistance, good stiffness and the like.
