Abstract
The invention relates to a making method of water absorption lining paper for sanitary napkins. The method adopts 100% native coniferous wood pulp long fiber, and by means of fibrillation treatment by a pulping machine, fiber combination can meet the strength requirement and maintain good air permeability at the same time. Compared with the prior art, the method provided by the invention adopts 100% long fiber, performs pumping reasonably, reduces excessive cutting of fiber, and reaches certain strength through reasonable fibrillation. The produced water absorption lining paper has high air permeability much higher than similar quantitative ordinary household paper, can package fluff pulp and the like uniformly, and the whole production process does not apply glue and is not added with dry strength agent, softening agent or other chemical medicines, thus being safe, sanitary and environment-friendly.
Description
Technical field
The present invention relates to a kind of preparation method of paper products, the making side of water suction lining paper is used more particularly, to a kind of sanitary napkin
Method.
Background technology
With the improvement of living standards, disposable sanitary articles industry development is rapid, disposable sanitary articles it is main excellent
Point is easy to use, comfortable, and the lining paper that absorbs water is the critical component in disposable sanitary articles, is mainly used for wrapping up sanitary napkin
Time of Fluff Slurry and hydroscopic high-molecular resin, it is ensured that amenities has certain water imbibition, and the gas permeability for having needed, high saturating
Gas can reduce discomfort in use.Because of its special use occasion and requirement, it is desirable to which the lining paper that absorbs water has
Certain and intensity and highly-breathable.Common paper for daily use on the market such as facial tissue, tissue, toilet paper, napkin paper, for kitchen use
Paper, tissue etc. with the addition of various chemicals because of the requirement of purposes, and air permeability is low, can not meet its use requirement.And
The method of parcel Time of Fluff Slurry is vacuum cloth slurry when sanitary napkin is produced, and it requires that water suction lining paper has air permeability very high.Air permeability
Higher, Time of Fluff Slurry is just scattered more uniform, you can wrapped is more uniform.Meanwhile, air permeability is higher, and absorption speed is faster, its
Using effect is better.The production of the disposable sanitary articles such as sanitary napkin and also require that it has certain physics strong using characteristic
Degree, it is impossible to have dust, it is impossible to have big eye, it is impossible to the chemicals such as addition is dry, wet strength agent.
The content of the invention
The purpose of the present invention provides a kind of reduction for the defect for overcoming above-mentioned prior art to exist to fiber
Excessively cut-out, the sanitary napkin preparation method of water suction lining paper of certain intensity is reached by rational wire-dividing broom purification.
The purpose of the present invention can be achieved through the following technical solutions：
The preparation method that a kind of sanitary napkin uses water suction lining paper, using 100% primary softwood pulp fibre long, by fiberizer
Wire-dividing broom purification treatment so that combined between fiber and preferable gas permeability is kept while meet intensity requirement, the method use with
Lower processing step：
(1) in softwood pulp input pulper, it is size degradation 10~20 minutes after 5.0~8.0wt% to add water to concentration, is pumped into
Fibre long kowtows preceding stock tank；
(2) kowtow preceding stock tank to fibre long and add water adjustment softwood pulp concentration to by fiberizer, passing through after 4.0~5.0wt%
Control defibrination power kowtows rear stock tank into fibre long afterwards to a certain extent to fiber treatment；
(3) softwood pulp pumps into blending chest in kowtowing rear stock tank from fibre long, from blending chest add water adjustment concentration to 3.0~
4.0wt% enters machine chest afterwards to a certain extent by controlling defibrination power by fiberizer to fiber treatment；
(4) slurry is diluted to concentration for 2.7~3.1wt% through thickening water, by fan pump, into paper machine shaping, pressure
Squeeze and dry, that is, make and obtain sanitary napkin water suction lining paper.
It is 15-19 to fiber treatment to fiber beating degree that defibrination power is controlled in step (2)оSR, weight in wet base 15-20g, herein
In the case of fiber between can be best combination, while intensity is obtained, the requirement of gas permeability can be met.
Control defibrination power is processed fiber again in step (3) so that fiber beating degree 16-20оSR, weight in wet base 14-
18g, thereby may be ensured that the suitable strength between fiber is combined, and production and use demand be met, while gas permeability can be met
Requirement.
Compared with prior art, the present invention has advantages below：
(1) fine using 100% length, rationally mashing reduces the excessive cut-out to fiber, is reached by rational wire-dividing broom purification
Certain intensity.
(2) the water suction lining paper of this technique productions has highly-breathable, and air permeability is far above identical quantitative common life
With paper, can be by the very uniform of the parcels such as Time of Fluff Slurry.
(3) whole production process not applying glue, without the chemicals such as drying strengthening agent, softening agent, safety, health, ring
Protect.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.
