Ultra-thin composite absorption core

Abstract

The invention discloses an ultra-thin composite absorption core. The absorption core includes a flow guiding layer and a skin-friendly layer. The flow guiding layer is fixed on the lower surface of the skin-friendly layer, the middles of the upper surfaces of the skin-friendly layer and the flow guiding layer are provided with bulges, the middles of the tops of the bulges are provided with grooves, the bottoms of the grooves are fixedly provided with support cylinders, the side walls of the support cylinders are provided with water permeable holes communicated with the insides of the support cylinders, the inner sides of the bulges are provided with first cavities, the bottoms of the first cavities are fixedly provided with first isolation layers, the lower portion of the flow guiding layer is fixedly provided with a bottom layer, a second cavity is formed between the bottom layer and the flow guiding layer, the first cavities and the second cavity are filled with water absorption materials, the second cavity is internally provided with a second isolation layer, and the top and bottom of the second isolation layer are fixed with the flow guiding layer and the bottom layer respectively. The ultra-thin composite absorption core can absorb excreta of infants intensively, the thickness of water absorption materials in other areas is reduced, and the daily activities of the infantsare facilitated.

Description

technical field [0001] The invention relates to the technical field of paper diapers, in particular to an ultrathin composite absorbent core. Background technique [0002] The core key technology of diapers is the "core". The absorbent core is the most important component of disposable absorbent products. The performance of disposable absorbent products is mainly determined by the absorbent core, such as water absorption, retention, diffusibility, etc. . [0003] The traditional absorbent core uses water-absorbing particles as the absorbent structure, and the thickness of the water-absorbing particles in each area of ​​the core is basically the same. Because the position where the baby excretes body fluids is relatively concentrated, the water-absorbing particles at the edge of the core are not fully utilized, resulting in water absorption. The waste of material, and the thickness of the water-absorbing material of the core body of this structure is bigger, just can guarant...

[0003] The traditional absorbent core uses water-absorbing particles as the absorbent structure, and the thickness of the water-absorbing particles in each area of ​​the core is basically the same. Because the position where the baby excretes body fluids is relatively concentrated, the water-absorbing particles at the edge of the core are not fully utilized, resulting in water absorption. The waste of materials, and the thickness of the water-absorbing material of the core body of this structure is relatively large, so as to ensure the complete absorption of body fluids, which brings great inconvenience to the activities of infants and young children.
