Embodiment 1

[0044] Such as figure 2 with image 3 As shown, an absorbent core includes a first layer 1 and a second layer 3 distributed up and down, and a diffusion layer 2 is arranged between the first layer and the second layer; the first layer 1 and the diffusion layer There is a layer of first superabsorbent resin layer 6 and a layer of first filling layer 4 stacked in sequence between 2, the first superabsorbent resin layer 6 has a rectangular hollow part 601; the diffusion layer 2 and the second A layer of second filling layer 5 and a layer of second superabsorbent resin layer 7 stacked in sequence are arranged between the two layers 3 .

[0045] The diffusion layer 2 is provided with a plurality of holes 11 penetrating through the upper surface and the lower surface of the diffusion layer. The plurality of holes 11 are divided into at least two rows, and the holes in each row of holes are distributed sequentially along the length direction of the core body. The filling layer is...

Embodiment 2

[0048] Such as Figure 4 As shown, repeating Example 1, only exchanging the positions of the first superabsorbent resin layer 6 and the first filling layer 4, and the positions of the second filling layer 5 and the second superabsorbent resin layer 7, can also obtain the 1 similar effect.

Embodiment 3

[0050] Such as Figure 5 As shown, repeat Example 2, only add a layer of first superabsorbent resin layer between the first filling layer and the first layer, and add a layer of second superabsorbent resin layer between the second filling layer and the second layer The resin layer can obtain a greater effect than that of Example 2 in terms of liquid absorption.

Abstract

The invention relates to an absorption core and a manufacturing method thereof. The absorption core comprises a first layer and a second layer which are vertically distributed. At least one diffusionlayer is arranged between the first layer and the second layer. At least one first high-hydroscopicity resin layer and at least one first filling layer are arranged between the first layer and the diffusion layer, and the first high-hydroscopicity resin layer is provided with a hollowed-out part. At least one second high-hydroscopicity resin layer and at least one second filling layer are arrangedbetween the diffusion layer and the second layer. The core is high in liquid passing performance, high in absorption speed and good in multi-absorption effect.

Description

technical field [0001] The invention relates to an absorbent core body and a manufacturing method, belonging to the field of sanitary products. Background technique [0002] Common composite cores currently on the market, such as figure 1 As shown, it is generally composed of the outermost two layers of dust-free paper 8, the middle layer of non-woven fabric 9 and two layers of SAP10 (super absorbent resin). The middle layer of this type of core is generally fluffy non-woven fabric, and the superabsorbent resin is directly spread on both sides of the fluffy non-woven fabric and partially embedded in the fluffy non-woven fabric. This kind of structure makes the product have poor liquid permeability and the upper layer absorbs water The resin is clogged due to viscose reaction, and the seepage speed of the liquid absorbed many times is slow, the diffusion length is short, and the overall utilization rate of the core body is poor, which leads to the leakage of urine when the l...
