Abstract

The utility model provides a three-layer composite paper diaper core belongs to paper diaper technical field. The core body of the paper diaper comprises a first absorption layer, a middle layer and a second absorption layer; the first absorption layer is positioned above the middle layer and is formed by mixing fluffy cloth and high-molecular water-absorbent resin; the middle layer is made of pure wood pulp fiber; the second absorption layer is positioned below the middle layer and is formed by mixing fluffy cloth and high-molecular water-absorbent resin. After the urine is initially absorbed by the first absorption layer, the urine enters the middle layer, is diffused under the action of wood pulp fibers, and is further absorbed by the third absorption layer after being diffused, so that the urine is fully absorbed, and the dryness of the paper diaper is kept.

Description

Three-layer composite paper diaper core

Technical Field

The utility model belongs to the technical field of panty-shape diapers, concretely relates to three-layer composite panty-shape diapers core.

Background

The paper diaper is a sanitary article commonly used by infants, and at present, the structure of the paper diaper on the market generally comprises a surface hydrophilic composite layer, two side anti-side leakage composite layers, a bottom anti-leakage water-repellent composite layer and an absorber positioned in the middle. The absorbent consists of an upper hydrophilic non-woven fabric layer, a lower hydrophilic non-woven fabric layer and an absorbent core positioned between the upper hydrophilic non-woven fabric layer and the lower hydrophilic non-woven fabric layer, and the performance of the core body determines the performance of the paper diaper.

The paper diaper has two types, one is formed by mixing fluff pulp and water-absorbent resin, and the other is formed by compounding dust-free paper, fluffy cloth and absorbent resin. At present, the second type is mainly used in the market, but the paper diaper core has the defects of poor diffusivity, poor multiple-time absorption and the like, after the core absorbs urine for multiple times, the conduction and diffusion performance of the core is poor, the core can be completely diffused after a long time, the absorption efficiency is low, the surface of the paper diaper is wet, discomfort is caused to infants, and even more, the skin of the infants generates rubella.

It follows that the prior art has certain drawbacks.

Disclosure of Invention

In view of this, in order to solve the problem in the prior art, a three-layer composite diaper core ensures that the core fully absorbs and diffuses urine, and keeps the dryness of the diaper.

The utility model discloses an above-mentioned problem is solved to following technical means:

a three-layer composite paper diaper core comprises a first absorption layer, a middle layer and a second absorption layer; the first absorption layer is positioned above the middle layer and is formed by mixing fluffy cloth and high-molecular water-absorbent resin; the middle layer is made of pure wood pulp fibers; the second absorption layer is positioned below the middle layer and is formed by mixing fluffy cloth and high-molecular water-absorbent resin.

The working principle is as follows: after the paper diaper core absorbs urine, the urine is firstly primarily absorbed by the high-molecular water-absorbent resin of the first absorption layer, and a storage space for the absorbed urine is provided by the fluffy cloth of the first absorption layer; when urine flows to the middle layer, the middle layer is made of pure wood pulp fibers, and due to the capillary phenomenon of the wood pulp fibers, the middle layer has good conduction and diffusion performance, and the absorbed urine can be fully and uniformly diffused; the uniformly diffused urine continuously flows to the third absorption layer under the action of the third absorption layer, so that the urine is fully absorbed, and the dryness of the paper diaper is kept.

Further, the three-layer composite paper diaper core body also comprises a bottom layer and a surface layer; the surface layer is positioned above the first absorption layer; the bottom layer is positioned below the third absorbent layer.

Further, the bottom layer and the surface layer are made of hydrophilic non-woven fabrics or wet strength paper.

Furthermore, the three-layer composite paper diaper core further comprises a wrapping layer, wherein the wrapping layer is used for comprising the core, and the wrapping layer forms a folding part above the surface layer.

Further, the wrapping layer is made of hydrophilic non-woven fabric.

Furthermore, the surface layer, the first absorption layer, the middle layer, the second absorption layer, the bottom layer and the wrapping layer are fixed in a pressing mode through hot melt adhesives or ultrasonic waves.

Compared with the prior art, the utility model has the advantages as follows:

the utility model discloses a first absorbed layer is after the preliminary absorption urine, and the urine gets into the intermediate level, diffuses under wood pulp fiber's effect, further absorbs through the third absorbed layer after the diffusion for the urine fully absorbs, keeps the dry and comfortable of panty-shape diapers.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the three-layer composite diaper core comprises a first absorption layer 1, a middle layer 2 and a second absorption layer 3; the first absorption layer 1 is positioned above the middle layer 2, and the first absorption layer 1 is formed by mixing fluffy cloth and high-molecular water-absorbent resin; the middle layer 2 is made of pure wood pulp fiber; the second absorption layer 3 is positioned below the middle layer 2, and the second absorption layer 3 is formed by mixing fluffy cloth and high-molecular water-absorbent resin.

The working principle is as follows: after the core body of the paper diaper absorbs urine, the urine is firstly primarily absorbed by the macromolecular water-absorbent resin of the first absorption layer 1, and a storage space for the absorbed urine is provided by the fluffy cloth of the first absorption layer 1; when urine flows to the middle layer 2, the middle layer 2 is made of pure wood pulp fibers, and due to the capillary phenomenon of the wood pulp fibers, the middle layer 2 has good diffusion performance, and the absorbed urine can be fully and uniformly diffused; the uniformly diffused urine continuously flows to the third absorption layer under the action of the third absorption layer, so that the urine is fully absorbed, and the dryness of the paper diaper is kept.

As shown in fig. 1, in this embodiment, the three-layer composite diaper core further includes a bottom layer 5 and a surface layer 4; the surface layer 4 is positioned above the first absorption layer 1; the bottom layer 5 is located below the third absorbent layer. By arranging the bottom layer 5 and the surface layer 4, the first absorption layer 1 and the second absorption layer 3 are effectively prevented from being exposed.
