Embodiment 1

[0039] ① Disintegration: Add plant fiber into the pulper, and decompose it into the pulp tank through the pulper, and add fillers to the pulp tank at the same time, and control the dry pulp concentration of the pulp to 3.6%, of which coniferous wood accounts for 15% of the total mass of plant fibers, hardwood accounts for 85% of the total mass of plant fibers, and fillers account for 30% of the total mass of fillers and plant fibers.

[0040] ② Refining: Use a double-disc refiner to beat the pulp, the beating degree is controlled at 25°SR, and the wet weight is controlled at 4.5g.

[0041] ③ Ingredients: add cationic starch with an amount of 1.0% and a wet strength agent with an amount of 0.5% in the slurry after refining. As a specific implementation, the wet strength agent in this example adopts polyamide epoxy resin .

[0042] ④Dilution and purification: The slurry after batching is diluted to control the concentration of the feedstock, and the concentration of the feedsto...

[0048] ① Disintegration: Add plant fiber into the pulper, and decompose it into the pulp tank through the pulper, add fillers to the pulp tank at the same time, and control the dry pulp concentration of the pulp to 4%, of which coniferous wood accounts for 25% of the total mass of plant fibers, hardwood accounts for 75% of the total mass of plant fibers, and fillers account for 20% of the total mass of fillers and plant fibers.

[0049] ② Refining: Use a double-disc refiner to beat the pulp, the beating degree is controlled at 32°SR, and the wet weight is controlled at 5.5g.

[0050] ③Batching: Add cationic starch with an amount of 1.25% and a wet strength agent with an amount of 0.75% to the slurry after refining. As a specific implementation, the wet strength agent in this example adopts polyamide epoxy resin .

[0051] ④Dilution and purification: The slurry after batching is diluted to control the concentration of the feedstock, and the concentration of the feedstock is co...

Embodiment 3

[0057] ① Disintegration: Add plant fiber to the pulper, and decompose it into the pulp tank through the pulper, and add fillers to the pulp tank at the same time, and control the absolute dry pulp concentration of the pulp to 4.2%, of which coniferous wood accounts for 30% of the total mass of plant fibers, hardwood accounts for 70% of the total mass of plant fibers, and filler accounts for 15% of the total mass of fillers and plant fibers.

[0058] ② Refining: use a double-disc refiner to beat the pulp, the beating degree is controlled at 35°SR, and the wet weight is controlled at 6.5g.

[0059] ③Batching: Add cationic starch with an amount of 1.5% and a wet strength agent with an amount of 1.0% to the slurry after refining. As a specific implementation, the wet strength agent in this example adopts polyamide epoxy resin .

Abstract

A process for producing raw paper by thermal dye sublimation is related to the technical field of papermaking and includes: pulping coniferous wood and broad-leaved wood in a mass ratio of 15:85-30:70 through a pulper, and adding a filling material, the mass ratio of plant fiber to the filling material being 70:30-85:15; subjecting obtained pulp to pulp grinding under controlled beating degree of 25-35 degrees SR, and adding a cationic starch and a wet strength agent respectively into the pulp; performing dilution purification, web-forming and pressing, and subjecting obtained wet paper sequentially to primary drying, surface gluing, secondary drying and tertiary drying to obtain the thermal dye sublimation raw paper. Indexes of the thermal dye sublimation raw paper such as tear, uniformity, shrinkage, tensile strength and smoothness can be effectively controlled, preventing the problems occurring during use of raw paper produced by traditional process, such as picking, poor printing effect, wrinkling during printing, and proneness to breakage during printing.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production process of thermal sublimation base paper. Background technique [0002] Sublimation transfer printing technology uses inkjet printing to print special printing dyes on paper, and then heats and pressurizes to transfer the dyes to fabrics. Sublimation transfer printing products have the advantages of good printing effect, soft hand feeling, long service life, simple process, less equipment investment, strong flexibility, high authenticity rate, resource saving, and environmental protection. With the continuous development of thermal sublimation transfer printing technology and people's recognition and dependence on thermal sublimation transfer printing products, thermal sublimation transfer printing technology has developed rapidly in my country, and its application fields have become more and more extensive. [0003] Sublimation base paper, as the carrier of su...
