[0028] Embodiment:

[0029] As Figures 1 - 4 shown, the present utility model provides a technical solution for a highly permeable water-absorbing paper:

[0030] As shown in the figure, a highly permeable water-absorbing paper, its structure includes layer 1, a middle layer structure 2 laid on the upper surface of the bottom layer 1 and bonded thereto, and a surface layer 3 provided on the upper surface of the middle layer structure 2. The middle layer structure 2 includes a limiting elastic layer 21 cooperating with the bottom layer 1, a folding layer 22 provided above the limiting elastic layer 21, a water guide strip 23 connected to the raised position above the folding layer 22, and a water absorption layer 24 located on the surface of the folding layer 22;

[0031] The folding layer 22 is composed of a plurality of triangular frames, and a water guide strip 23 is connected to the top position of the triangular frame.

[0032] The lower surface of the surface layer 3 is provided with upper and lower arched grooves 31, which can make the water absorption of the surface layer uniform, and improve the water permeability and high-efficiency water absorption of the water body.

[0033] The groove 31 cooperates with the water guide strip 23.

[0034] The limiting elastic layer 21 includes an embedded elastic band.

[0035] The water absorption layer 24 is filled in the internal position of the triangular frame of the folding layer 22 and the triangular frame position composed of two adjacent folding layers 22, which can improve the water absorption degree of the water-absorbing paper.

[0036] The surface of the folding layer 22 is provided with dotted openings to facilitate the penetration of the water body.

[0037] The adjacent surfaces of the two folding layers 22 are coated with a waterproof paper coating to improve the water isolation between the adjacent folding layers, thereby enhancing the overall performance of the paper.

[0038] The water absorption layer 24 is composed of highly water-absorbent fibers.

[0039] The bottom layer 1 is made of polyethylene (PE) film.

[0040] Its specific implementation principle is as follows: After the water-absorbing paper comes into contact with the water body, the water body passes through the water guide strip 23 of the raised part provided on the surface layer 3 to uniformly penetrate and absorb the water body, thereby improving the uniform penetration and water absorption on the surface of the paper body. The water body absorbed by the water guide strip 23 is then absorbed by the water absorption layer 24, and the structure of the triangular frame of the folding layer 22 is utilized, and the dotted openings provided on its surface facilitate the penetration of the water body to the lower water absorption layer 24.

[0041] After being absorbed by the water absorption layer 24, and cooperating with the provided limiting elastic layer 21, the folding layer 22 can be made to expand and swell as a whole, thereby improving the high-permeability water absorption effect of the water-absorbing paper.
