Embodiment Construction

[0028] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] This embodiment provides a preparation process for a base paper material for superabsorbent paper towels, comprising the following steps:

[0030] The first step, pulping: Put the softwood pulp and hardwood pulp into the hydropulper for crushing, and add chemical mechanical pulp at the same time to improve the paper tightness and supplement the long fiber content, and add beating enzyme when the wood pulp is crushed ;

[0031] The second step, slag removal: the disintegrated slurry is deslagging through a slag remover to remove coarse and heavy impurities to prevent abrasion of the refiner or residues entering into paper;

[0032] The third step, refining: transport the pulp after deslagging to the refiner for refining, and the refining power is 20-40kwh / t pulp;

[0033] The fourth step, sizing: the slurry is diluted with white water, enters...

Abstract

The invention relates to the field of paper towel production, in particular to a preparation process of a high-water-absorption paper towel base paper material, which comprises the following steps: repulping: repulping softwood pulp and hardwood pulp, adding chemimechanical pulp at the same time, and adding pulping enzyme when the wood pulp is repulped; slag removal: performing slag removal treatment on the slurry through a slag remover; pulping: conveying the pulp into a pulping machine for pulping; sizing: diluting the slurry with white water, and then feeding the diluted slurry into a sizing system for deslagging and screening; adding chemicals: adding a wet strength agent, a control agent and a bactericide in the sizing process after grinding; papermaking: feeding the screened pulp into a papermaking machine for papermaking to obtain raw paper of the high-water-absorption paper towel; forming on a net: controlling the pulp-net speed ratio to be 0.89-0.94 J / W; drying in a drying cylinder: drying on the surface of the drying cylinder, and uniformly spraying a drying cylinder coating on the surface of the drying cylinder during drying; and wrinkling: wrinkling the paper surface by using a wrinkling scraper. The technical problems that the water absorption performance of the paper towel is poor, and paper is wasted are solved.

Description

technical field [0001] The invention relates to the field of paper towel production, in particular to a preparation process of a base paper material for a superabsorbent paper towel. Background technique [0002] At present, paper towels, as a kind of household paper, are mainly used in toilets in public places such as airports, hotels, guesthouses, and office buildings. Toilet paper is a disposable household paper made of natural plant fibers (wood fiber, bamboo fiber, straw pulp fiber, cotton fiber, etc.) Compared with other products, this product has the advantages of higher quantitative, good wet strength, and not easy to break. For example, Chinese Patent Publication No.: CN108570875B discloses a production process for environmentally friendly high-grammage paper towels. The high-grammage paper towels are prepared through two steps: a stock preparation process and a paper-making process. The stock preparation process includes long fiber pulp. Pulping treatment, pulpin...
