The present invention relates to a kind of preparation method of high-air-permeability lining paper, softwood pulp is put into pulper, concentration is added water to as size degradation after 5.0~7.0wt% and is pumped into long fibre and kowtows preceding stock tank；Softwood pulp adds water to adjust concentration to stock tank through defibrination and after kowtowing into long fibre after 4.5~5.0wt% in stock tank before long fibre is kowtowed；Softwood pulp after processing is imported into machine chest；Slurry is pumped into header box again, and then through fan pump, while it is 0.2~0.3wt% to be diluted with water concentration, into paper machine headbox, adds dispersant, then upper net forming, squeezes dry, cylinder dried through vacuum carrying roller and wrinkle into paper.Compared with prior art, this high-air-permeability lining paper is mainly used for using carrying during dry-papermaking machine production water uptake core material to Time of Fluff Slurry and water-absorbing resin, it is necessary to the air permeability higher than lining paper used in common sanltary towel, baby paper diaper production.
Description
Technical field
The present invention relates to a kind of preparation method of paper, more particularly, to a kind of preparation method of high-air-permeability lining paper.
Background technology
With the raising of the level of consumption, disposable nursing materials market development is rapid, and it is handle to have a kind of new mode of production
Water uptake core material containing Time of Fluff Slurry, water-absorbing resin etc. is directly placed into inside, this directly to place water uptake core material production water suction production
The technique of product can improve production efficiency, simplify technique, improve product quality.This water uptake core material is to use dry-papermaking machine
Produce, high-air-permeability lining paper is mainly when using dry-papermaking machine production water uptake core material, and lining exists in its forming process
Bottom, by vacuum suction, by the absorption of the powdery mixing such as Time of Fluff Slurry, water-absorbing resin absorbent material on this lining paper, then pass through
Embossing, glue spraying, drying process are crossed, produces water uptake core material finished product, this finished product can be cut into different size and be placed directly in health
Absorbent material is used as inside towel, paper diaper, medical bed mattress etc., due to the requirement of actual use, this lining paper must have it is very high and
Uniform air permeability and certain intensity, absorbent material are to be anchored at by vacuum above this layer of lining paper, and high air permeability can be with
Ensure production efficiency, uniform air permeability can ensure that absorbent material is uniformly distributed, and certain intensity is because being used as water-absorption material
The carrier of material, it is necessary to assure dry-papermaking machine is under certain speed of production, by processes such as embossing, glue sprayings, and as health
Material, it is impossible to add any chemicals that can increase intensity.But existing domestic lining paper product can not meet air permeability simultaneously
With the requirement of intensity, when intensity is higher, gas permeability is poor, and intensity is poor when gas permeability is preferable.
Chinese patent CN101058956A discloses the manufacture method of high ventilating adsorption lining paper, using natural wood pulp as raw material,
Including pulping, desanding, discongest, the step such as copy paper, the wood pulp of use is made up of needle slurry and broad-leaved slurry mixing, and wherein needle is starched
Shared part by weight is 80-90%, and part by weight shared by broad-leaved slurry is 10-20%, and mashing electric current is 320-340A, online of manufacturing paper with pulp
Concentration is 0.05%.The lining paper of patent production is to be directly used in the production process of sanitary napkin, paper diaper to go to wrap up Time of Fluff Slurry
And water-absorbing resin.This produced with the application for water uptake core material lining paper and differ, this water uptake core material contains suede
Hair slurry and water-absorbing resin, can be cut into all size according to customer requirement, can be directly placed into when producing sanitary napkin, paper diaper
Inside, without using Time of Fluff Slurry, water-absorbing resin both raw materials again.In addition, the patent with the addition of hardwood pulp, and originally
Application is to use 100% softwood pulp, and except raw material is different, the application is also in squeeze pressure, remover, sticker cylinder agent, crepe ratio
Aspect has adjusted.After the patent with the addition of hardwood pulp and wet strength agent, drying strengthening agent, other are not adjusted particularly, so thoroughly
Manner will be far below the application, require very high to air permeability in the production process of water uptake core material, the patent is to meet
Water uptake core material production needs.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind has very high breathe freely
The preparation method of the lining paper of performance.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of preparation method of high-air-permeability lining paper, this method use following steps：
(1) softwood pulp is put into pulper, adds water to concentration to carry out size degradation, beating time after 5.0~7.0wt%
15~20min, obtained softwood pulp are pumped into long fibre and kowtow preceding stock tank；
(2) softwood pulp stock tank before long fibre is kowtowed add water adjust concentration to after 4.5~5.0wt% by fiberizer to fiber
Cut off and wire-dividing broom purification, obtained softwood pulp are pumped into long fibre and kowtow rear stock tank；
(3) softwood pulp after processing is imported into machine chest；
(4) slurry is pumped into header box again, and then through fan pump, while it is 0.2~0.3wt% to be diluted with water concentration, is entered
Enter paper machine headbox, while add dispersant of the dosage in 0.3-0.5kg/ ton paper, then upper net forming, by vacuum carrying roller pressure
Drain it is dry, then by cylinder dried and on drying cylinder corrugation into paper.
Described defibrination Power Control is at 100-120 kilowatts.
Described dispersant is PEO dispersants.
Without using remover in drying cylinder Wrinkling, using only sticker cylinder agent and modifying agent.
Described sticker cylinder agent is the sticker cylinder agent that the commercially available trade mark is 33A, and addition is 1.2-1.8kg/ ton paper, and described changes
Good dose be the commercially available trade mark be 115A modifying agent, addition is 0.3-0.7kg/ ton paper.
Vacuum carrying roller squeeze pressure is 0.4-0.5MPa.
The steam pressure of cylinder dried is 0.72-0.74MPa.
Crepe ratio is controlled in 22-25%.
Compared with prior art, the present invention has advantages below：
(1) 100% softwood pulp is used, needle-leaved wood fibre is relatively thick longer, and Inter-fiber voids are larger.Reduce carrying roller squeezing pressure
Power, drying cylinder steam pressure is improved, reduce press dewatering, dry as far as possible to keep page fluffy.In Wrinkling, sticker cylinder agent is used
Amount is very big, and cylinder finishing coat is harder, and small pinprick can be produced during corrugation, and makes fiber more fluffy using higher crepe ratio, so
Making obtained lining paper has very high air permeability, it is ensured that in the production process of water uptake core material, Time of Fluff Slurry and water suction are set
Fat can be quickly absorption on lining paper, using this water uptake core material be used for disposable sanitary articles production, life can be simplified
Production. art, improve production efficiency；
(2) softwood pulp is the best wood-fibred of intensity, then by slight defibrination, fiber is slightly fluffed, brooming, increase
Interfibrous intertexture power, the lining paper for obtaining making have certain intensity, it is ensured that production normal operation；
(3) raw material is 100% Original Pulp, safety, health；
(4) lining paper of this technique productions does not add any enhancing chemicals.
