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, especially relate to the preparation method of a kind of sanitary napkin water suction lining paper.
Background technology
Along with growth in the living standard, disposable sanitary articles industry development is rapid, the major advantage of disposable sanitary articles is easy to use, comfortable, and the lining paper that absorbs water is the critical component in disposable sanitary articles, be mainly used for parcel sanitary napkin Time of Fluff Slurry and hydroscopic high-molecular resin, can ensure that amenities has certain water imbibition, and the gas permeability needed, highly-breathable can reduce discomfort in use.The use occasion special because of it and requirement, require that water suction lining paper has certain and intensity and highly-breathable.Common paper for daily use on the market if facial tissue, tissue, toilet paper, napkin paper, paper for kitchen, tissue etc. are because of the requirement of purposes, and with the addition of number of chemical medicine, and air permeability is low, can not meet its instructions for use.And the method for parcel Time of Fluff Slurry is vacuum cloth slurry during sanitary napkin production, so require that water suction lining paper has very high air permeability.Air permeability is higher, and it is more even that Time of Fluff Slurry is just disperseed, can be wrapped more even.Meanwhile, air permeability is higher, and absorption speed is faster, and its result of use is better.The production of the disposable sanitary articles such as sanitary napkin and operating characteristic also require that it has certain physical strength, can not have dust, can not have large eye, can not add the chemicalss such as dry, wet strength agent.
Summary of the invention
Object of the present invention is exactly provide a kind of minimizing to the excessive cut-out of fiber to overcome defect that above-mentioned prior art exists, and the sanitary napkin reaching certain intensity by rational wire-dividing broom purification absorbs water the preparation method of lining paper.
Object of the present invention can be achieved through the following technical solutions:
A preparation method for sanitary napkin water suction lining paper, adopts 100% primary softwood pulp long fine, and through the wire-dividing broom purification process of fiberizer, make to keep good gas permeability while combination meets requirement of strength between fiber, the method adopts following processing step:
(1) softwood pulp drops in pulper, and adding water to concentration is size degradation 10 ~ 20 minutes after 5.0 ~ 8.0wt%, pumps into long fibre and kowtows front stock tank;
(2) kowtowing front stock tank to long fibre adds water through fiberizer after adjustment softwood pulp concentration to 4.0 ~ 5.0wt%, enters long fibre to a certain extent afterwards kowtow rear stock tank by controlling defibrination power fiber treatment;
(3) softwood pulp is kowtowed in rear stock tank from long fibre and is pumped into blending chest, adds water adjustment concentration to 3.0 ~ 4.0wt% through fiberizer from blending chest, enters machine chest afterwards by controlling defibrination power to a certain extent to fiber treatment;
(4) through thickening water, to be diluted to concentration be 2.7 ~ 3.1wt% to slurry, through fan pump, enters that paper machine is shaped, pressing and drying, namely makes to obtain sanitary napkin and to absorb water lining paper.
Controlling defibrination power in step (2) to fiber treatment is 15-19 to fiber beating degree
osR, weight in wet base 15-20g, combination that can be best between fiber in the case, while obtaining intensity, can meet the requirement of gas permeability.
Control defibrination power in step (3) again to process fiber, make fiber beating degree 16-20
osR, weight in wet base 14-18g, thus can ensure that the suitable strength between fiber combines, meet and produce and user demand, the requirement of gas permeability can be met simultaneously.
Compared with prior art, the present invention has the following advantages:
(1) adopt 100% long fibre, rationally pull an oar, reduce the excessive cut-out to fiber, reach certain intensity by rational wire-dividing broom purification.
(2) the water suction lining paper of this explained hereafter has highly-breathable, and air permeability is far above identical common paper for daily use quantitatively, and that Time of Fluff Slurry etc. can be wrapped up is very even.
(3) whole production process not applying glue, the chemicals such as dry strength agent, softener is not added, safety, health, environmental protection.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
