While using absorbent article of the present invention, liquid is entering after the top flat of liquid permeable, before contact absorber, first needs to see through the clad of coated absorber; The present invention, by impress some special floral designs on clad, can effectively improve the absorption rate of clad, thus the absorbability of corresponding raising absorbent article.
Description
Technical field
The present invention relates to a kind of absorbent article.
Background technology
At present common disposable absorptive articles for use, it generally includes: directly contact the also top flat of liquid permeable with skin, the egative film of impermeable liquid, and be arranged on the absorbed layer of the absorption liquid between top flat and egative film.
For disposable absorptive articles for use, conventionally need very fast being absorbed of liquid. In order to improve the absorption rate of disposable absorptive articles for use, the normal method adopting has at present: select the more easily top sheet materials of infiltration; Guide layer is set below top flat, and this guide layer uses untreated Time of Fluff Slurry; Efficient super absorbent polymer (SuperAbsorbentPolymer, SAP) is set in absorbed layer; In topsheet surface, guiding gutter is set, guiding gutter is set together with on top flat at absorbed layer, or at absorbed layer, top flat, guiding gutter etc. is all set together with on egative film. But these conventional modes, cost is all higher and have limitation aspect absorption rate improving.
Summary of the invention
In view of this, provide a kind of absorbent article that can further improve absorption rate.
A kind of absorbent article, it comprises the top flat of liquid permeable, the egative film of non-liquid permeable, and be arranged on the absorber between top flat and egative film, two apparent surfaces of described absorber are coated with respectively a clad, and this two clad is separately positioned between top flat and absorber, between absorber and egative film; Described two clads have at least one to be formed with embossed pattern through embossing processing.
While using absorbent article of the present invention, liquid is entering after the top flat of liquid permeable, before contact absorber, need to first see through the clad of coated absorber. The present invention by impressing some embossed patterns on clad, thereby form high density area in embossed area, embossed area is not low density area relatively, due to capillarity, the absorption rate of meeting accelerating liquid, thereby the absorbability of corresponding raising absorbent article.

Following detailed description of the invention further illustrates the present invention in connection with above-mentioned accompanying drawing.
Detailed description of the invention
Refer to Fig. 1, absorbent article 100 of the present invention comprises with skin and directly contacting and the top flat 10 of liquid permeable, the egative film 50 of impermeable liquid, and be arranged on the absorber 30 that absorbs liquid between top flat 10 and egative film 50. The upper and lower surface of described absorber 30 is also coated with respectively a clad 40. This two clad 40 is separately positioned between top flat 10 and absorber 30, between absorber 30 and egative film 50.
This clad 40 can be as a whole coated absorber 30, or the upper and lower surface of absorber 30 is respectively arranged with independently clad 40, and the upper and lower surface that these two kinds of modes all can realize absorber 30 is all coated with a clad 40.
The material of this top flat 10 is the nonwoven cloth material of liquid permeable or the polyethylene of liquid permeable (PE) film.
The material of this egative film 50 is the nonwoven cloth material of impermeable liquid or the polyethylene of impermeable liquid (PE) film.
The material of this absorber 30 can be the mixture of string, string and chemical fibre or the mixture of fiber and high-hydroscopicity chemical material.
The material of this clad 40 can be the mixture of string, string and chemical fibre or the mixture of fiber and high-hydroscopicity chemical material. Preferably super absorbent resin of this high-hydroscopicity chemical material, as polyacrylic resin.
Described two clads 40 have at least one to be formed with embossed pattern through embossing processing, the clad 40 being preferably arranged between top flat 10 and absorber 30 is formed with embossed pattern through embossing processing, and more preferably this two clad 40 is all formed with embossed pattern through embossing processing.
Embossing mode can be some the mode to the various prior aries such as recessed or point-to-point to flat, point. Refer to Fig. 2, be formed with embossed area 41 and embossed area 43 not through clad 40 surfaces of embossing, the thickness of embossed area 41 is less than the not thickness of embossed area 43, and the thickness of embossed area 41 is the 10%-90% of the thickness of embossed area 43 not, be preferably 40%-80%, more preferably 50%-60%. Embossed area 41 is formed as high density area, and embossed area 43 is not formed as relative low density area. In the time having liquid to infiltrate, due to capillarity, can accelerating liquid absorption rate.
The capillarity that the principle of utilization of the present invention produces while being liquid-soaked thin paper. Wherein capillarity is followed formula below:
Height or width that in formula, h express liquid infiltrates, γ presentation surface tension force, θ represents contact angle, ρ express liquid density, g represents acceleration of gravity, r represents tubule radius.
Correspond to clad 40 of the present invention, this h gets final product ability or the speed of express liquid infiltration clad 40, is also that h is larger, and liquid more easily or sooner infiltrates this clad 40; R can represent the pore-size in thin paper. In same specific environment, γ, θ, ρ and g all can be considered it is certain, therefore determine that the speed of liquid-soaked thin paper is only r, are also the pore-size of clad 40. And process embossing is afterwards because embossed area 41 is longitudinally compressed, with respect to embossed area 43 not, r is less for its fiber tubule, therefore liquid can spread rapidly in embossed area 41, then be diffused at leisure not embossed area 43, relatively accelerate absorption rate, thus the absorbability of corresponding raising absorbent article 100.
Clad 40 surfaces through embossing are formed with embossed pattern, and the size of pattern, shape, layout, density etc. can design as required, and its shape can be regular or irregular. As shown in Figure 2, described embossed pattern can be the embossing striped being parallel to each other, and embossing striped forms impression, makes clad 40 surfaces form the structure that is similar to guiding gutter, liquid is infiltrated in impression fast, thereby improve absorption rate. Described embossing striped can be vertical striped, also can be designed to the striped of other shapes, as waveform striped, zigzag striped, grid striped. Described embossed pattern also can add some little embossing on the basis of embossing striped, as rhombus, rectangle, circle or other erose embossing, to increase the area of embossed area, further improves the absorption rate of clad 40. In order better to improve absorption rate, also can make the embossed pattern of described clad 40 mutually link up at longitudinal and horizontal direction, form crisscross guide trough structure.
Understandable, absorbent article 100 of the present invention is arranging on the basis of the clad 40 with embossed pattern, also can adopt some conventional modes further to improve absorption rate, as selected the more easily top sheet materials of infiltration; The guide layer of Time of Fluff Slurry material is set below top flat; Efficient super absorbent polymer is set in absorber; Guiding gutter etc. is set.
While using absorbent article 100 of the present invention, liquid is entering after the top flat 10 of liquid permeable, before contact absorber 30, need to first see through the clad 40 of coated absorber 30. The present invention, by impress some special floral designs on clad 40, can effectively improve the absorption rate of clad 40, thus the absorbability of corresponding raising absorbent article 100.
In addition, those skilled in the art also can make various amendments, interpolation and the replacement in other form and details in the claims in the present invention scope of disclosure and spirit. Certainly, the variations such as various amendments, interpolation and the replacement that these make according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
