Description
Technical Field
The utility model relates to a disposable hygienic articles field especially relates to a fluffy ventilative disposable absorption articles for use.
Background
Disposable absorbent articles are primarily referred to as feminine sanitary napkins, baby diapers, adult incontinence devices, whose primary function is to absorb and contain body exudates. The existing disposable absorption article mainly comprises a liquid-permeable surface layer, an absorption core body and a liquid-impermeable bottom layer which are sequentially laminated from top to bottom, wherein the absorption core body is the key for the quality of the disposable absorption article. Fluff pulp is a fibrous material capable of rapidly and effectively absorbing liquid, and an absorbent body combined with Super Absorbent Polymer (SAP) is a structure commonly used in the prior art, so that the fluff pulp can greatly reduce the back permeation of the liquid and leave enough time for the Super Absorbent Polymer (SAP) to absorb the liquid. Although the absorbent core added with the fluff pulp has the effects of fast water absorption and uniform diffusion, the absorbent core is relatively loose in structure and is not added with an adhesive, so that the phenomena of lumping and fault are easily caused. If fluff pulp is not put into the absorption core body, Super Absorbent Polymer (SAP) is directly adopted, so that the cost can be reduced, the SAP does not rise and continuously layer, and is lighter and thinner, but the defect that the absorption speed is lower, liquid can permeate back to the surface of skin, the SAP after absorbing the liquid becomes hard, and the comfort level of a user can be reduced by not putting soft fluff pulp.
SUMMERY OF THE UTILITY MODEL
Therefore, in view of the above, the present invention provides a fluffy and breathable disposable absorbent article, which solves the problem of lump and fault easily arising during the use of the disposable absorbent article in the prior art.
In order to achieve the purpose, the utility model is realized by the following technical proposal: the utility model provides a fluffy ventilative disposable absorbent articles for use, definition absorbent articles have along length direction vertically and width direction's horizontal, including absorbing the main part, absorb the main part including the liquid-permeable surface course, absorption core and the liquid-tight nature bottom that from top to bottom set up of stromatolite in proper order, liquid-permeable surface course includes hydrophilic non-woven fabrics and locates the hydrophobic non-woven fabrics of its horizontal both sides, its characterized in that: the liquid permeable absorption core is characterized in that a flow guide layer is arranged between the liquid permeable surface layer and the absorption core body, the absorption core body is formed by wrapping the absorption core by a hydrophilic thin layer material, the absorption core comprises a fluffy cotton layer and a water absorption material, first fluff pulp is distributed between the flow guide layer and the absorption core body at intervals, a glue layer is filled at each interval, the interval between every two adjacent first fluff pulp is 5-50mm, the width of each first fluff pulp is 5-50mm, and the liquid impermeable bottom layer is formed by compounding a breathable film and non-woven fabrics arranged at the bottom of the breathable film.
The further improvement is that: the water-absorbing material is high water-absorbing resin particles or high water-absorbing fibers.
The further improvement is that: second fluff pulp is distributed between the absorption core body and the liquid-tight bottom layer at intervals, and glue layers are filled at the intervals.
The further improvement is that: the projected areas of the second fluff pulp and the first fluff pulp in the longitudinal direction are not overlapped.
The further improvement is that: the gram weight of the first fluff pulp and the gram weight of the second fluff pulp are both 5-200g/m2。
The further improvement is that: the hydrophilic thin layer material is non-woven fabric or wet strength paper.
The further improvement is that: the basis weight of the fluffy cotton layer is 20-200 gsm.
The further improvement is that: the basis weight of the water-absorbing material is 50-600gsm
By adopting the technical scheme, the beneficial effects of the utility model are that: the fluffy cotton is adopted to replace fluff pulp, and the absorption core body combined with the high water absorption resin or the high water absorption fiber can not generate the phenomena of lump and fault. Fluffy cotton has the thermoplasticity, and when absorbing core and water conservancy diversion layer hot melt adhesive, can reduce the use amount of hot melt adhesive under the prerequisite of guaranteeing adhesive strength, makes the thickness attenuation of absorbing the core simultaneously. The first fluff pulp is distributed between the flow guide layer and the absorbent core at intervals, and the second fluff pulp is distributed between the absorbent core and the breathable film at intervals, so that the liquid diffusion and absorption performances can be further improved.
