According to some preferred embodiments, the elastic waistline 1 is formed by compounding non-woven fabrics and rubber bands; wherein the number of the rubber bands is at least 10 (for example, 10, 12, 15, 18 or 20 can be provided);
the non-woven fabric is at least one selected from hot air non-woven fabric or spun-bonded non-woven fabric.
According to some preferred embodiments, both the liquid-permeable surface layer 5 and the flow-guiding layer 6 are at least one selected from the group consisting of a through-air nonwoven, a spunbond nonwoven or a spunlace nonwoven;
according to some preferred embodiments, the liquid-permeable surface layer 5 is provided with guide pressure grooves.
At least one of them is a mixture of any one or any several of them mixed in any ratio.
In the invention, the liquid-permeable surface layer is folded downwards, and the flow guide layer and the absorption core body are semi-wrapped, so that the flow guide layer and the absorption core body are in a suspension structure relative to the breathable bottom layer, and the absorption area of liquid is increased; meanwhile, the liquid-permeable surface layer is made of fine and soft hot air, spun-bonded or spunlace non-woven fabrics, is comfortable to directly contact with the skin of a user, can quickly absorb liquid, and can be better infiltrated and diffused by matching with the flow guide pressure groove of the surface layer, so that the liquid is prevented from being concentrated on the surface layer to influence the use feeling.
According to some preferred embodiments, the absorbent core 7 comprises a wrapping layer 8 and an absorbent layer 9; wherein the wrapping layer 8 is used for wrapping the absorption layer 9;
according to some preferred embodiments, the wrapping layer 8 is at least one selected from the group consisting of dust-free paper, wet-strength paper, or nonwoven fabric.
According to some preferred embodiments, the absorbent layer 9 is compounded from wet strength paper, fluff pulp and super absorbent resin; wherein the fluff pulp and the superabsorbent resin are between two layers of wet strength paper;
the mass ratio of the fluff pulp to the super absorbent resin is (8-15): (2-10) (e.g., 8: 2, 8: 5, 8: 10, 10: 2, 10: 5, 10: 10, 15: 2, 15: 5, 15: 8, or 15: 10).
It should be noted that, in the invention, the absorption layer is formed by compounding the fluff pulp, the super absorbent resin and the wet strength paper, and the fluff pulp and the super absorbent resin are uniformly mixed according to the proportion and are compounded between the wet strength paper, so that the liquid absorption performance and the diffusion performance of the absorption layer are greatly improved.
According to some preferred embodiments, the upper surface of the network of channels is located on the surface of the absorbent core 7 and the lower surface of the network of channels is located in the absorbent layer 9; wherein, the depth of the reticular diversion trench is 50-100% (for example, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 90%, 95% or 100%) of the thickness of the absorption layer;
the shape of the reticular diversion trench is at least one selected from diamond, square, circle or hexagon.
It should be noted that the depth of the mesh-shaped guiding groove is the vertical dimension from the upper surface to the lower surface of the mesh-shaped guiding groove.
In the invention, the reticular diversion grooves of the absorption core body are uniformly arranged on the absorption layer and the wrapping layer above the absorption layer, and extend towards the thickness direction of the position of the absorption core body, the rapid absorption and rapid diffusion of liquid are realized by utilizing the reticular structure of the diversion grooves, and the depth of the reticular diversion grooves can be adjusted according to actual requirements; the experiment proves that when the depth of the reticular diversion trench is 50-100% of the thickness of the absorption layer, the liquid can be rapidly absorbed and diffused, and reverse osmosis is reduced; when the depth of the reticular diversion trench is small, the absorption speed and the diffusion speed of the liquid are low, so that the liquid is concentrated at the liquid infiltration part, the dryness of the surface layer is affected, and even the liquid is subjected to side leakage.
In the present invention, the shape of the mesh-shaped flow guide groove includes, but is not limited to, the above-mentioned shape, and any shape satisfying the mesh shape may be used. For example, when the mesh-shaped channels are rhombus, square or hexagon, the side length of the channels is 2-8cm, and when the mesh-shaped channels are circular, the diameter of the circle is 3-5cm, and if the mesh-shaped channels are too large or too small, the absorption speed and diffusion speed of the liquid are affected.
According to some preferred embodiments, the containment flaps 4 are attached to the breathable bottom layer 10 and to the liquid-permeable top layer 5; wherein the three-dimensional enclosure is 2-5 cm higher than the liquid-permeable surface layer (for example, 2cm, 2.5cm, 3cm, 3.5cm, 4cm, 4.5cm or 5 cm);
the three-dimensional enclosure 4 is at least one selected from hot air water-repellent non-woven fabrics or spun-bonded water-repellent non-woven fabrics.

the base film non-woven fabric 11 is at least one selected from hot air water-repellent non-woven fabrics or spun-bonded water-repellent non-woven fabrics.
It should be noted that, because the PE breathable film is relatively soft, and the bottom layer of the PE breathable film is relatively poor in three-dimensional property and is easily deformed, in the present invention, the breathable bottom layer is formed by compounding the bottom film nonwoven fabric and the PE breathable film, and the bottom film nonwoven fabric is connected with the three-dimensional enclosure, thereby avoiding the problem that the bottom film is deformed due to the direct contact of the three-dimensional enclosure and the PE film.
According to some preferred embodiments, the leg leakage-proof edge 3 is formed by compounding a PE breathable film and a water-repellent non-woven fabric; wherein the PE breathable film is attached to the leg part;
at least one circle of elastic material (for example, one circle, two circles, three circles or four circles) is arranged between the PE breathable film and the water-repellent non-woven fabric.
The more the number of turns of the elastic material of the leg leakage preventing edge is, the more the elastic material can be tightly attached to the leg, but when the number of turns is too large, the binding feeling of the leg is increased, and the use feeling of the user is affected.
According to some preferred embodiments, the first side of the leg leakage preventing edge 3 is 15 to 30cm (for example, it may be 15cm, 18cm, 20cm, 25cm, 28cm or 30 cm); wherein the first side length is used for representing the length of the leg leakage preventing edge extending from the elastic waistline to the leg direction; the second side length of the leg leakage-proof edge 3 is 5-20cm (for example, 5cm, 8cm, 10cm, 15cm or 20 cm); wherein the second side length is used for representing the length of the leg leakage preventing edge extending from the absorber to the leg direction.
It should be noted that, in the invention, the leg leakage-proof edge is formed by compounding the PE breathable film and the water-repellent non-woven fabric, the PE breathable film is relatively soft, the PE breathable film is relatively comfortable to be attached to the leg, the water-repellent non-woven fabric is arranged on the outer layer to increase the stiffness, and meanwhile, the elastic material is arranged between the PE breathable film and the water-repellent non-woven fabric, so that the leg leakage-proof edge is more attached to the leg, and further, the liquid side leakage can be effectively prevented.
In the present invention, the first side of the leg leakage preventing edge corresponds to the long side of the leg leakage preventing edge, and the second side corresponds to the short side of the leg leakage preventing edge. In the invention, the leg leakage-proof edges are too long, which not only reduces the use comfort of users, but also increases the cost; if the leg leakage-proof edge is too short, the side leakage cannot be effectively prevented, so that the liquid side leakage can be effectively prevented without causing a restraining feeling to a user within the scope of the present invention.
