Problems solved by technology

As a result, after the disposable absorbent article absorbs urine or menstrual blood many times, the volume of the superabsorbent polymer is greatly increased due to the absorption of liquid, and the absorbent core will expand under the action of pressure or shear force with the movement of the wearer. Partial accumulation into clusters and faults in other parts not only affect the effect of secondary liquid absorption, but also affect the comfort of wearing

Embodiment 1

[0015] like figure 1 As shown, is a schematic cross-sectional view of a disposable absorbent article, which can be used in sanitary napkins, baby diapers and adult diapers. The disposable absorbent article comprises a liquid-permeable topsheet 2, a liquid-impermeable backsheet 4, and an absorbent core 3 between the liquid-permeable topsheet 2 and the liquid-impermeable backsheet 4. The liquid-permeable topsheet material 2 and the liquid-impermeable backsheet material 4 are preferably flexible and non-irritating to the wearer's skin, and are various known materials used in disposable absorbent articles.

[0016] The absorbent core 3 is a structure composed of fluff pulp fibers and superabsorbent polymers 35 that are evenly mixed with a fluffy non-woven fabric 31. Both sides or one side of the fluffy non-woven fabric 31 have long fibers, and the fluff pulp fibers and fluff pulp fibers and The superabsorbent polymer 35 is wrapped up, and the long fibers 32 on the side of the flu...

Embodiment 2

[0019] like figure 2 As shown, the absorbent core 3 is a structure composed of evenly mixed fluff pulp fibers and superabsorbent polymer 35 wrapped by a fluffy non-woven fabric 31. The width of the fluffy non-woven fabric 31 before being wrapped can be slightly greater than twice the width of the absorbent core 3, The fluff non-woven fabric 31 is folded upwards and inwards on both sides of the width of the mixture of fluff pulp fibers and superabsorbent polymer, and wraps the mixture of fluff pulp fibers and superabsorbent polymer. The fluffy nonwoven fabric 31 wrapped with fluff pulp fibers and superabsorbent polymer 35, except that one side is hot-pressed and the other side is fluffy, on the fluffy side, in addition to the long fibers of the fluffy part forming a network skeleton structure, there are also a considerable part of long fibers The fluffy side of the non-woven fabric protrudes to form individual fiber portions 33 . In this embodiment, in addition to the skeleto...

Embodiment 3

[0021] The absorbent core 2 has two layers, the upper and lower layers, and the fluff pulp fiber and the super absorbent polymer are clamped and wrapped by the fluff pulp fiber and the super absorbent polymer slightly larger than the fluff pulp fiber and the super absorbent polymer 35 in the width of the fluffy non-woven fabric 31 in the absorbent core. The fluffy non-woven fabric 31 adopts the scheme of embodiment 1 or embodiment 2.

Abstract

A disposable absorption object contains a permeable surface layer, a non-permeable bottom layer and an absorption core between the surface layer and the bottom layer, wherein the absorption core is prepared by using a fluffy non-woven fabric to cover fluff pulp fibers and super absorbent polymers; one side or both sides of the fluffy non-woven fabric have filaments, the filaments at the side facing toward to the fluff pulp fibers and super absorbent polymers, of the fluffy non-woven fabric are used to form a netted skeleton structure while fluff pulp fibers and super absorbent polymers are covered in the fluffy non-woven fabric and distributed in the netted skeleton formed by the filaments of the fluffy non-woven fabric; and the skeleton structure is crosslinked with a part of fluff pulp fibers, and the crosslinking part has cohesive force. By adopting the disposable absorption object, the condition that after the super absorbent polymer in the absorption core absorbs bodily excretion and swells, the local super absorbent polymers are packed and agglomerated and the other part of the layer is broken, can be prevented, and the core strength of the absorption core can be effectively increased.

Description

technical field [0001] The present invention relates to a disposable absorbent article, and more particularly to a disposable absorbent article having an improved absorbent core structure. Background technique [0002] Currently, many different types of disposable absorbent articles such as diapers, incontinence pads, sanitary napkins, etc. are widely used on the market. Most of these absorbent articles have a similar structure: a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent core between the liquid-permeable topsheet and the liquid-impermeable backsheet. The absorbent core is capable of receiving and containing liquids, such as body exudates. Absorbent cores are usually made from an intimate blend of fluff pulp fibers and superabsorbent polymers. A liquid-permeable topsheet is used to provide a comfortable and dry feel upon contact with the body, while allowing liquids to pass freely to the underlying absorbent core. The liquid-impermeable b...
