Embodiment Construction

[0017] See figure 1 , figure 1 A schematic structural view of the composite absorbent core of the present invention is shown. Such as figure 1 As shown, the composite absorbent core comprises a topsheet 1 , an intermediate absorbent layer 2 and a backsheet 3 . The middle absorbent layer 2 is sandwiched between the top layer 1 and the bottom layer 3 .

[0018] The surface layer 1 can be made of materials with liquid-permeable function, such as water-permeable dust-free paper or water-permeable non-woven fabric. The bottom layer 3 can be made of liquid-impermeable material, such as water-repellent non-woven fabric. Of course, the bottom layer 3 can also be made of the same or similar material as the surface layer 1 as required.

[0019] The middle absorbent layer 2 can adopt traditional materials, such as fluffy non-woven fabric material, fluffy fiber paper and other materials. The key feature of the present invention is: the middle absorbent layer 2 is provided with longi...

Abstract

The invention provides a composite absorption core comprising a surface layer, a bottom layer and a middle absorption layer. The middle absorption layer is arranged between the surface layer and the bottom layer, and is provided with a plurality of vertical through holes. The vertical through holes are filled with macromolecular water-absorbent resin. The composite absorption core has the advantages that the through holes are formed in the middle absorption layer and are filled with the macromolecular water-absorbent resin, filling quantity of the macromolecular water-absorbent resin is increased, and accordingly, liquid absorption quantity of the composite absorption core can be increased.

Description

technical field [0001] The present invention relates to an absorbent article for daily use, in particular to an absorbent core with a composite structure, which can be applied to various disposable absorbent articles, such as disposable diapers, women's sanitary napkins and the like. Background technique [0002] The absorbent core is the most critical and important part of a disposable absorbent product. The performance of disposable absorbent articles, such as water absorption, retention, etc., is largely determined by the absorbent core. [0003] In the prior art, the absorbent core generally includes a surface layer, a bottom layer and an intermediate layer arranged between the surface layer and the bottom layer, and the absorbent material is fixed on the surface of the intermediate layer by means of bonding or the like. When the absorbent core contacts liquid such as water, the liquid passes through the surface layer to reach the middle layer, and is absorbed and held ...
