AI Technical Summary
The existing water-absorbing paper core lacks a flow-guided design, which causes the liquid to be unable to effectively guide to the absorption area, which easily leads to the water-absorbing paper core being agglomerated and lacks breathability.
Design an ultra-thin breathable water-absorbing paper core, including the surface layer, the flow guide layer, the bottom layer and the high-loop non-woven fabric layer. The arrangement of the flow guide groove and the flow guide hole divides the high-loop non-woven fabric layer into multiple strips of water-absorbing The layer, flow guide holes and flow guide grooves improve breathability, and the surface layer is equipped with breathable grooves and raised to fill tea powder to enhance absorption and anti-inflammatory and antibacterial effects.
It achieves rapid absorption and breathability of liquid, avoids the agglomeration of water-absorbing paper core, enhances dryness and anti-inflammatory and antibacterial effects, and maintains the ultra-thinness of the paper core.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary products, and more specifically to an ultra-thin and breathable water-absorbing paper core. Background Art
[0002] Diapers are daily necessities commonly used by babies. They are another name for diapers, paper diapers or pull-up pants. Dry diapers can keep babies sleeping all night. Due to their strong water absorption, they are commonly known as "diapers". The absorbent paper core of diapers contains super absorbent polymer (SAP for short), which has an amazing water absorption and water storage capacity.
[0003] Although the existing absorbent paper core has good water absorption, it lacks a diversion design and cannot guide the liquid to the effective absorption area, which easily causes the absorbent paper core to agglomerate. Utility Model Content
[0004] The purpose of the utility model is to provide an ultra-thin and breathable absorbent paper core in order to solve the above technical problems.
[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0006] An ultra-thin breathable absorbent paper core comprises a surface layer, a guide layer, a bottom layer and a high-loft non-woven fabric layer arranged between the guide layer and the bottom layer, wherein the high-loft non-woven fabric layer is evenly spread with polymer absorbent particles, a plurality of guide grooves evenly spaced apart are arranged on the high-loft non-woven fabric layer, and the guide layer is provided with guide holes aligned with the guide grooves.
[0007] Structural principle: The high-loft non-woven fabric layer is divided into multiple strip-shaped water-absorbing layers by setting the guide grooves, so that the liquid can be directed to each water-absorbing layer to achieve rapid absorption and avoid concentrated absorption and agglomeration. The setting of the guide holes allows the liquid to quickly penetrate into the guide grooves. The setting of the guide holes and guide grooves improves the overall air permeability of the absorbent paper core.
[0008] The surface layer is provided with a plurality of ventilation grooves evenly spaced and arranged, and the ventilation grooves have the function of guiding and ventilating to avoid excessive concentration of liquid and enhance dryness.
[0009] The bottom of the guide groove is provided with a plurality of evenly distributed protrusions, and the protrusions are filled with tea powder. The tea powder not only brings a fresh fragrance, but also has anti-inflammatory and antibacterial effects.
[0010] The cross section of the guide groove is arranged to be an inverted trapezoid.
[0011] The absorbent paper core has a thickness of less than 2 mm. Setting the absorbent paper core to less than 2 mm makes the absorbent paper core as a whole ultra-thin and breathable, not easy to deform, and has good water absorption.
[0012] The surface layer is dust-free paper, the bottom layer is non-woven fabric, and the flow-guiding layer is a fluff pulp layer.
[0013] The beneficial effects of the utility model are as follows:
[0014] In the utility model, the high-loft non-woven fabric layer is divided into a plurality of strip-shaped water-absorbing layers by setting the guide groove, so that the liquid is guided to each water-absorbing layer to achieve rapid absorption and avoid concentrated absorption and agglomeration. The setting of the guide hole allows the liquid to quickly penetrate into the guide groove. The setting of the guide hole and the guide groove improves the overall air permeability of the absorbent paper core. The protrusion is filled with tea powder. The tea powder not only brings a fresh smell, but also has anti-inflammatory and antibacterial effects. The setting of the ventilation groove has the function of guiding and ventilating to avoid excessive concentration of liquid and enhance dryness. BRIEF DESCRIPTION OF THE DRAWINGS
