Description
Technical field
The present invention relates to external use sanitary absorbent article field, relate in particular to a kind of disposable absorbent article.
Background technology
At present the absorbed layer of the product such as diaper on the market, sanitary towel is mostly single layer structure, often adopts wood pulp and macromolecule to absorb mixed with resin and forms.Wood pulp mainly plays conduction diffusion, and macromolecule absorption resin mainly plays Absorption, macromolecule absorbs resin ratio major part between 30%～50%, the in the situation that of equal absorbent properties, but it is can partially thick diffusion better that 30%～40% macromolecule absorbs the product of resin ratio, can thinner diffusion poor but 40%～50% macromolecule absorbs the product of resin ratio.
For this reason, there is technical staff that a kind of absorbent device of absorbent layer structure of multilamellar is provided, to increase assimilation effect.For example, Chinese patent literature CN101347373B open " a kind of fibrilia sanitary absorbent articles ", it comprise the top layer of liquid permeable, the bottom of impermeable liquid and be located in described top layer and described bottom between moisture absorption layer, described moisture absorption layer comprises the moisture absorption sheet of one or more layers overlapping placement, described moisture absorption sheet comprises the flaxen fiber of smashing and the magma paper of smashing, and described in described moisture absorption sheet, the content of flaxen fiber is 10-90WT%.Although the absorbent device of this structure is than the good absorbing effect of the absorbent device of existing monolayer absorbed layer, but the flaxen fiber of the inside of its moisture absorption layer of every layer is all the same with the ratio of magma paper, therefore in order to guarantee corresponding diffusion, it is thicker that its thickness will inevitably be done, reduce the comfort of user, also increased cost simultaneously.
In addition, the absorbed layer of the existing absorbent device with multi-layer absorber layer adopts different formation systems to make mostly, then through stack and extruding, combine again, such absorbent device thickness is thicker, and the gap between adjacent absorbed layer is larger, and gap can store liquid, increases the milliosmolarity of returning of absorbent device, be unfavorable for the absorption of liquid, reduced the comfort of absorbent device.
