Description
Technical field
The present invention relates to a kind of disposable adsorption objects, have the disposable of improvement absorbent core structures more particularly, to a kind of
Absorbing articles and the preparation process for being related to this disposable adsorption object.
Background technology
The disposable adsorption objects such as existing baby paper diaper, incontinent adults' articles for use are well-known.This kind disposable
Absorbing articles are most of all to have similar structure, that is, has：Permeable top layer, opaque liquid bottom and permeable top layer
With the absorbent cores between opaque liquid bottom.The absorbent cores can receive and accommodate liquid, such as slop, for example, urine or
Menses etc..Absorbent cores usually by hydrophilic fibre net package fluff pulp fibers and super absorbent polymer mixed core system into.
Permeable top layer is used to provide comfortable and dry and comfortable feeling when contacting with body, while liquid is allowed to pass freely through, under
The absorbent cores in face.Opaque liquid bottom is used to retain the liquid absorbed in an absorbent core, so as to prevent absorbed liquid
The clothes of dirty wearer.
If the body fluid of urine is after by permeable top layer, it is temporarily stored in fluff pulp fibers, it is then super
Absorbing polymeric absorbs and super absorbent polymer is swollen, and the fluid preservation absorbed is lived, super absorbent polymer can increase
Add the absorptive capacity of absorbent cores.When increasing super absorbent polymer to improve the water absorbability of absorbing articles or reduce
When absorbent cores are so as to reduce the thickness of absorbing articles, the amount of fluff pulp fibers should be just reduced.In the case, the suede in absorbent cores
The ratio of hair pulp fibres and super absorbent polymer is with regard to relative reduction, and the crosslinking between fluff pulp fibers is also reduced.It is tied
Fruit is, disposable adsorption object after repeatedly urine or menses are absorbed, the volume of super absorbent polymer because absorbing liquid and
Greatly increase, absorbent cores with the movement of wearer will appear under the action of pressure or shearing force local accumulation it is agglomerating and other
Tomography situation occurs for position, not only affects the effect for absorbing liquid, has an effect on the comfort of dress.
In the prior art, have using scheme of the blotting paper processed as absorbent cores, can solve to tie better
The defects of group, fracture.However, using scheme of the blotting paper processed as absorbent cores, the cost of raw material is higher, performance
By the performance of the blotting paper processed, therefore, stability is poor.In the prior art without one kind by disposable
Property absorbing articles production line directly process the technique of blotting paper, also come out in the prior art not over the technique productions primary
Property absorbing articles.
