Description

Disposable absorption article

Technical Field

The utility model relates to a disposable absorption article, in particular to a disposable absorption article which is comfortable to wear and can quickly permeate and absorb excrement.

Background

Disposable absorbent articles for absorbing liquids include diapers, nursing pads, sanitary napkins, panty liners and the like. The existing disposable absorbent articles generally comprise a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorbent core between the liquid-permeable surface layer and the liquid-impermeable bottom layer, wherein the existing absorbent core comprises a mixed absorbent core structure formed by mixing wood pulp fibers and super absorbent polymers and an absorbent paper structure formed by the super absorbent polymers and a plurality of non-woven fabric layers. When the absorbent core is used, excrement permeates from top to bottom, the upper layer structure of the absorbent core can reduce the infiltration speed of the excrement after the excrement is absorbed, and particularly, only the super-absorbent polymer on the upper layer of the absorbent paper consisting of the super-absorbent polymer and the non-woven fabric expands when the excrement is absorbed, so that the excrement is blocked to further downwards, and the excrement is easy to accumulate and leak. Therefore, it is required to provide a solution capable of effectively solving the problem of blocking the infiltration of excrement after the upper layer absorbs the excrement, so as to improve the absorption efficiency and wearing comfort of the absorbent article.

Detailed Description

The present invention will be further described with reference to the following detailed description.

As shown in FIGS. 1 to 3, the disposable absorbent article 1 comprises a liquid-permeable top sheet 11, a liquid-impermeable back sheet 13, and an absorbent core 12 between the liquid-permeable top sheet 11 and the liquid-impermeable back sheet 13.

The liquid-permeable top sheet 11 is formed of a material having a soft touch feeling by directly contacting the skin of the wearer, and a suitable liquid-permeable top sheet 11 may be made of many materials such as spun-bonded nonwoven fabric, spunlace nonwoven fabric, air-through nonwoven fabric, hot-rolled nonwoven fabric, and the like. The liquid-permeable top sheet 11 may be a porous molded film. The porous shaped film is preferably a three-dimensional porous shaped film that is permeable to bodily exudates, non-absorbent, and reduces fluid flowback to rewet the wearer's skin, thereby reducing body soiling and providing a more comfortable feel to the wearer.

The liquid-impermeable back sheet 13 may be made of a woven or nonwoven fibrous material that has been treated to be liquid-impermeable, a polymeric film, such as a thermoplastic film of polyethylene or polypropylene, or a composite material, such as a breathable film, with a nonwoven fabric. The liquid-impermeable back sheet 13 can allow moisture vapor to escape from the absorbent core (i.e., be breathable) while also preventing exudates from passing through the liquid-impermeable back sheet 14.

The absorbent core 12 comprises upper and lower absorbent cores, the lower layer being a first absorbent core 123, and the upper absorbent core comprising a second absorbent core 121 having an opening through its thickness in the center and a third absorbent core 122 received in the opening.

The first absorbent core 123 is provided with a bulky nonwoven layer on which a first polymer layer is provided; the fluffy non-woven fabric has certain fluffy degree, the fluffy non-woven fabric is placed under a presser foot, and a 25cN weight (the pressure is 0.1 kpa) is added on the presser foot of 2500mm 2. Taking a sample for measurement, reading after pressurizing for 10s, and recording as D1; the weight on the presser foot was then changed to 125cN (pressure 0.5 Kpa) and the thickness of the same sample was again measured and recorded as D2. The compressibility of the specimen thickness (D1-D2)/D1X 100% was calculated. If the compressibility is greater than 20%, the nonwoven fabric is regarded as bulky.

The second absorbent core 121 contains wood pulp fibers and a second polymer layer having a polymer density lower than that of the first polymer layer; the second absorbent core 121 is centrally provided with an open region free of wood pulp fibers and a second polymer layer, which extends through its thickness; the third absorbent core 122 is disposed in the open area of the second absorbent core 121, the third absorbent core 122 is made of a foam material, the second absorbent core 121 and the third absorbent core 122 are not in contact with each other, and there is a gap containing no absorbent material; a groove 124 recessed downward from the liquid-permeable surface layer 11 at the gap; the third absorbent core 122 is provided with apertures 122a through its thickness, and the liquid-permeable top sheet 11 is provided with corresponding apertures 11a corresponding to the apertures 122a of the third absorbent core 122. The excrement sets up more quick infiltration through the trompil and reaches the bottom, through the fluffy non-woven fabrics redistribution excrement of first absorption core, has improved the core utilization ratio when improving the leak protection effect.

The above-mentioned only be several concrete implementation manners of the present invention, nevertheless the design concept of the present invention is not limited to this, and all the time the present invention utilizes this concept to be right the present invention performs insubstantial modification, and all should belong to the act of infringing the protection scope of the present invention.
