Although the existing core body can absorb liquid, the absorption speed is slow, the contact time of skin and liquid is prolonged, the skin health is not good, and the probability of liquid overflow is increased. In addition, the existing core body can not better contain excrement, and the using effect and the comfort of the product are required to be improved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of prior art, the utility model provides a compound core with stronger absorption performance and holding performance, its be provided with supply the opening that the filth got into and with the filth accommodation space of opening intercommunication, enable liquid, fluid material or fixed concentrate and enter into to filth accommodation space from the opening, then liquid absorbs through the core main part, the absorption rate is very fast, the filth holding performance is better.

A composite core with stronger absorption performance and holding performance comprises a flaky core body, wherein the core body comprises a first dust-free paper layer, a first non-woven fabric layer, a first high-molecular water-absorbent resin layer, a second dust-free paper layer, a second high-molecular water-absorbent resin layer, a second non-woven fabric layer and a third dust-free paper layer, the first non-woven fabric layer is thermally sealed below the first dust-free paper layer, the first high-molecular water-absorbent resin layer is glued below the first non-woven fabric layer, the second high-molecular water-absorbent resin layer is glued below the first high-molecular water-absorbent resin layer, the second high-molecular water-absorbent resin layer is glued below the second dust-free paper layer, the second non-woven fabric layer is glued below the second high-molecular water-absorbent resin layer, and the third dust-free paper layer is thermally sealed below the second non-woven fabric layer; an opening for dirt to enter is formed in the first dust-free paper layer, and a dirt containing space communicated with the opening is formed between the first dust-free paper layer and the first non-woven fabric layer.

Furthermore, the opening is arranged in the middle of the first dust-free paper layer, so that the opening corresponds to the urination and defecation organs of the human body, and the urine and the excrement can conveniently enter the opening smoothly; the area of the dirt containing space is larger than that of the opening, and the dirt containing space is approximately in an inverted T shape.

Furthermore, the opening is rectangular or oval, and the shape is convenient to set and also convenient to correspond to urination and defecation organs of a human body.

Furthermore, a plurality of through holes through which semifluid dirt can pass are distributed on the first non-woven fabric layer, so that flowing excrement can enter and diffuse.

The utility model has the advantages that: the water-absorbing resin layer is provided with a first high-molecular water-absorbing resin layer and a second high-molecular water-absorbing resin layer, and can absorb and contain more liquid by utilizing the strong water-absorbing capacity and water-retaining capacity of the water-absorbing resin layer, so that the liquid is prevented from overflowing; still including the opening that supplies the filth to get into and the filth accommodation space of opening intercommunication, enable liquid, fluid matter or fixed concentrated from the opening entering to filth accommodation space, then liquid absorbs through the core main part, and the absorption rate is very fast, and filth holding performance is better.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 4, a composite core having superior absorption and containment properties includes a sheet-shaped core body 1, the core body 1 including a first non-dust paper layer 2, a first non-woven fabric layer 3 thermally bonded under the first non-dust paper layer 2, a first high molecular water absorbent resin layer 4 glued under the first non-woven fabric layer 3, a second non-dust paper layer 5 glued under the first high molecular water absorbent resin layer 4, a second high molecular water absorbent resin layer 6 glued under the second non-dust paper layer 5, a second non-woven fabric layer 7 glued under the second high molecular water absorbent resin layer 6, and a third non-dust paper layer 8 thermally bonded under the second non-woven fabric layer 7; an opening 9 for dirt to enter is provided on the first dust-free paper layer 2, and a dirt-containing space 10 communicating with the opening 9 is provided between the first dust-free paper layer 2 and the first nonwoven fabric layer 3. The dirt refers to urine, blood, feces, etc. Specifically, the opening 9 is arranged in the middle of the first dust-free paper layer 2, so that the opening 9 corresponds to the urination and defecation organs of the human body, and urine and excrement can conveniently enter the opening; the area of the dirt-receiving space 10 is larger than that of the opening 9 and is substantially in the shape of an inverted T. The opening 9 is rectangular or oval, and the shape is convenient to set and corresponds to the urination and defecation organs of the human body. A plurality of through holes 11 which can allow semifluid dirt to pass through are distributed on the first non-woven fabric layer 3, so that the flowing excrement can enter and spread. The diameter of the through holes 11 is smaller than that of the water absorbent polymer particles 12, so that the water absorbent polymer particles 12 are prevented from coming out.

Heat sealing refers to joining two objects together by heating. Gluing refers to the joining of two objects together by means of an adhesive. The high molecular water-absorbing resin is called SAP for short, and is a typical functional high molecular material. It can absorb hundreds of times, even thousands of times its own weight of water and has a strong water-retaining capacity, so it is also called super absorbent or high water-retaining agent. In terms of chemical structure, the super absorbent resin is a low crosslinking degree or partially crystalline high molecular polymer having many hydrophilic groups.

It should be noted that: in this document, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
