Problems solved by technology

However, due to the unreasonable setting of the structural layer and the position of the absorbent polymer material in the existing absorbent articles, there are many problems in the wearing process of the existing absorbent articles: such as the absorbent core running away from the expected position, the absorbent core often breaks cotton or lumps , the diffusion path of the absorbent core liquid is broken, etc.
However, since the absorbent core is not compounded with other fiber layers with good diversion and diffusion, the overall absorbency of the core is poor and cannot meet the requirements of repeated liquid absorption.

Embodiment 1

[0039] like figure 1 As shown, a disposable absorbent article of the present invention comprises a liquid-permeable topsheet 1, a liquid-impermeable bottom layer 4 and an intermediate composite layer disposed between the topsheet 1 and the bottom layer 4. In this embodiment, the top layer 1 is a pure cotton non-woven fabric, and the material of this layer is required to absorb liquid quickly, and the grammage is 35g / m 2 , its infiltration time is 1.5s. The middle composite layer includes an absorbent core 2, and the absorbent core 2 includes a porous material layer 6 and two flow-guiding layers 5 arranged on the upper and lower sides of the porous material layer 6, and the pores of the porous material layer 6 are embedded with absorbent Sexual polymeric material7. In this embodiment, discrete absorbent polymer materials 7 are embedded between the porous material layer 6 and the flow guide layer 5, and the porous material layer 6 and the flow guide layer 5 are in contact with...

Embodiment 2

[0043] like figure 2 As shown, the disposable absorbent article of the present invention comprises a liquid-permeable topsheet 1, a liquid-impermeable backsheet 4 and an intermediate composite layer disposed between the topsheet 1 and the backsheet 4. The intermediate composite layer includes an absorbent core 2 , an auxiliary absorbent layer 3 arranged between the absorbent core 2 and the bottom layer 4 , and a wrapping layer 9 wrapped around the absorbent core 2 and the auxiliary absorbent layer 3 . The absorbent core 2 is the same as in Example 1. In this embodiment, the top layer 1 is a hydrophilic air-through non-woven fabric, and the material of this layer is required to absorb liquid quickly, and the grammage is 25g / m 2 , and its penetration time is 2.0s. In the present embodiment, the diversion layer 5 is 45g / m 2 Made of puffed paper. Porous material layer 6 is 45g / m 2 7DPET / PE fiber hot-air non-woven fabric, the penetration time of the non-woven fabric is 0.8s, ...

Embodiment 3

[0048] like image 3 As shown, the disposable absorbent article of the present invention comprises a liquid-permeable topsheet 1, a liquid-impermeable backsheet 4 and an intermediate composite layer disposed between the topsheet 1 and the backsheet 4. The middle composite layer includes an absorbent core 2 , an auxiliary absorbent layer 3 arranged between the absorbent core 2 and the top layer 1 , and a wrapping layer 9 wrapped around the absorbent core 2 and the auxiliary absorbent layer 3 . The absorbent core 2 is the same as in Example 1. The top layer 1 described in this implementation is a hydrophilic hot-rolled non-woven fabric, and the material of this layer is required to absorb liquid quickly, and the grammage is 20g / m 2 , its infiltration time is 2.2s. The diversion layer 5 can be made of different materials, one, the diversion layer 5 is 40g / m 2 The 7D PET chemically bonded non-woven fabric has a penetration time of 0.8s, a bulkiness of 0.5mm, a compression resis...

Abstract

The invention relates to the technical field of daily goods, in particular to a disposable absorption article such as paper diapers or sanitary towels. The disposable absorption article comprises a liquid permeable top layer, a liquid impermeable bottom layer and a middle compound layer arranged between the top layer and the bottom layer for absorbing and accommodating liquid; the middle compound layer comprises at least one absorption core body; the absorption core body comprises a porous material layer and two guide layers arranged on the upper surface and the lower surface of the porous material layer respectively; and an absorptive polymer material is embedded into holes of the porous material layer. The disposable absorption article has the advantages of simple structure, low manufacturing cost, and continuous cotton, no lump production, no demixing, good guide effect and the like when the disposable absorption article is full of liquid or partial of liquid.

Description

Technical field: [0001] The invention relates to an absorbent article for daily use, which belongs to the technical field of daily articles, in particular to a disposable absorbent article. Background technique: [0002] It is a conventional technical means for existing absorbent articles to use superabsorbent absorbent polymer materials to absorb moisture, because such superabsorbent absorbent polymer materials have the characteristics of large absorption capacity and the like. However, due to the unreasonable setting of the structural layer and the position of the absorbent polymer material in the existing absorbent products, there are many problems in the wearing process of the existing absorbent products: such as the absorbent core running away from the expected position, and the absorbent core often breaks or lumps , The diffusion path of the absorbent core liquid is broken, etc. [0003] WO95 / 17868 discloses an absorbent structure comprising two fibrous layers and an ...
