Problems solved by technology

The advantages and disadvantages of the two structures are very obvious. The core structure has good dryness and stability, and the product is ultra-thin, but the air permeability is poor; while the fluff pulp structure has good air permeability, but its absorber has poor stability and dryness.
[0003] However, an absorbent core structure that can combine the advantages of the two structures has not been reported yet.

Embodiment 1

[0044] A composite absorbent structure, including a core structure, including from top to bottom:

[0045] Surface layer 1, the weight is 80g / m 2 , wherein the surface layer 1 is made of a layer of superabsorbent resin composite paper, which is formed by evenly distributing superabsorbent resin between two layers of base paper made of wood pulp through wet papermaking Super absorbent resin composite paper;

[0046] The first superabsorbent resin layer 2, the grammage is 150g / m 2 , containing superabsorbent resin particles of D 70 25-50 mesh;

[0047] Middle layer 3 (fluffy non-woven fabric layer), the grammage is 40g / m 2 ;

[0048] The second superabsorbent resin layer 4, the gram weight is 150g / m 2 , containing superabsorbent resin particles of D 80 35-80 mesh;

[0049] The bottom layer 5 (dust-free paper layer), the weight is 40g / m 2 ;

[0050] Such as figure 2 As shown, the core structure is provided with an oval diversion groove 6 penetrating from the surface l...

Embodiment 2

[0052] A composite absorbent structure comprising a core structure such as figure 1 As shown, from top to bottom include:

[0053] Surface layer 1, the grammage is 100g / m 2 , wherein the surface layer 1 is made of a layer of superabsorbent resin composite paper, which is formed by evenly distributing superabsorbent resin between two layers of base paper made of wood pulp through wet papermaking Super absorbent resin composite paper;

[0054] The first superabsorbent resin layer 2, the grammage is 160g / m 2 , containing superabsorbent resin particles of D 70 25-50 mesh;

Abstract

The invention relates to a composite absorption structure which comprises a core structure, wherein the core structure sequentially comprises a surface layer, a first super absorbent resin layer, a middle layer, a second super absorbent resin layer and a bottom layer from top to bottom; the surface layer is made of super absorbent resin composite paper; and the core structure is provided with at least one flow guide groove penetrating from the surface layer to the bottom layer, and the flow guide grooves are filled with an absorption material formed by mixing fluff pulp and super absorbent resin. The composite absorption structure has the most outstanding characteristics of being good in surface dryness, good in air permeability, large in absorption capacity, high in absorption speed and softer, is suitable for being used as an absorption core of sanitary products such as paper diapers, sanitary towels and finished pants, and is particularly suitable for being used as the absorption core of the paper diapers.

Description

technical field [0001] The invention belongs to the technical field of absorbent cores, in particular to a composite absorbent structure. Background technique [0002] Common disposable absorbent products currently on the market include baby diapers, sanitary napkins for feminine hygiene products, and pants for adult incontinence products. Most of the absorbent cores of such disposable absorbent articles have similar structures: one is a core structure and the other is a fluff pulp structure. The advantages and disadvantages of the two structures are very obvious. The core structure has good dryness and stability, and the product is ultra-thin, but the air permeability is poor; while the fluff pulp structure has good air permeability, but the absorber has poor stability and dryness. [0003] However, no absorbent core structure capable of combining the advantages of the two structures has been reported so far. Contents of the invention [0004] In order to solve the tech...
