Production process of colored tissue paper

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...

Problems solved by technology

[0009] The disadvantage of the existing technology is that it needs to consume a large amount of softwood pulp, which is relatively harmful to the environment
