Embodiment Construction

[0034] The process of the present invention is further illustrated below through specific examples.

[0035] Total process flow:

[0036] (1) pulping

[0037] Put 100% waste paper pulp into the hydraulic pulper for disintegration, then remove impurities such as film by jumping sieve, then go through high-frequency disintegrator and single mill for beating, and finally add chemical raw materials and dyes to the pulping tank and adjust the concentration Backfeed papermaking approach flow system.

[0038] (2) Papermaking

[0039] The incoming pulp is diluted by flushing through the flushing tank, and then the long fibers and fiber bundles are removed by the slag remover and the rotor screen, and then pumped into the high-level box and flowed into the mesh tank to go online, and finally squeezed, dried, and rolled. Paper, cutting, packaging and storage.

Abstract

The invention discloses a process for producing colored tissue paper by using 100 percent of wastepaper pulp. The process comprises the following steps of: pulp preparation: adding 100 percent of wastepaper pulp into a hydrapulper for breaking; removing impurities of thin films and the like by using a jig sieve; pulping through a high-frequency fluffer and a raffinator; and finally adding chemical raw materials and dye in a pulp blending tank, adjusting the density and feeding the mixture into a paper-making flow delivering system; paper making: diluting the pulp for making in a slushing tank by slushing, then removing sand by a deslagger and long fibers and fiber bundles by a selectifier screen, pumping into a head box and flowing into a net trough for filtering through a net; and finally squeezing, drying, reeling, splitting, packaging and warehousing. The quality of products reaches the national quality standard of 100 percent of wood pulp products and further reaches over B class according to the national standard.

Description

[technical field] [0001] The invention relates to a colored tissue paper, in particular to its production process. [Background technique] [0002] Color tissue paper is a high-grade ultra-thin product packaging paper, which is widely used in the packaging of handicrafts. It has good vividness, brightness and light resistance, and can improve the external image and grade of products. The commonly used color tissue papers in China are red, black and green, and the sales volume is very large, while the sales volume of color tissue paper exported abroad is even greater. [0003] The process of existing colored tissue paper includes two parts of beating and papermaking in turn, and the specific process is as follows: [0004] (1) pulping [0005] Put 100% bleached softwood pulp into the hydropulper for disintegration, then beat through Φ450 double disc mill, and finally add chemical raw materials and dyes in the pulp mixing tank and adjust the concentration before sending it to...
