Detailed Description

In order to make the technical problems, technical solutions adopted and technical effects achieved by the present invention clearer, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Wherein the terms "first position" and "second position" are two different positions.

Fig. 1 to 4 show the preferred embodiment of the present invention, the sanitary napkin of the present invention, comprises a surface contact layer 1, an absorption core layer 3 and a bottom coating layer 7, which are arranged in sequence from top to bottom. The liquid flows from the surface contact layer 1 into the absorbent core layer 3, the absorbent core layer 3 absorbs and stores the exudate, and the undercoat layer 7 serves to prevent the exudate from leaking.

The surface contact layer 1 is directly contacted with the skin, and is made of a non-woven fabric material, preferably a hot air non-woven fabric, and the hot air non-woven fabric is a fluffy low-density non-woven fabric made of eccentric core sheath fibers and is softer and more comfortable; the non-compact fiber tissue can quickly permeate blood and improve the infiltration speed.

The surface contact layer 1 is provided with rhombic embossed patterns 4 with concave-convex stereoscopic impression and is provided with flow guide holes 5, the flow guide holes 5 can be arranged on the diamond edges or the diamond corners of the rhombic embossed patterns 4, and each diamond edge of each rhombic embossed pattern 4 can be provided with one or more flow guide holes 5. The middle part of the diamond-shaped embossing 4 forms a bulge 6 to increase the fluffy feeling. The shape of the diversion hole 5 can be round, oval or polygonal, etc., and the diversion hole 5 can not be too large, so as to avoid damaging the bulge 6.

The surface contact layer 1 is subjected to the special treatment, has weak hydrophilicity, enables single-point permeation, non-diffusion and low reverse osmosis on the surface, effectively reduces the residue of blood on the surface, and has the effect of fading the occult blood of menstrual blood.

Optionally, the sanitary napkin further comprises a flow guiding layer 2, the flow guiding layer 2 is arranged between the surface contact layer 1 and the absorption core layer 3, the flow guiding layer 2 is made of thick-denier low-density hot air non-woven fabric, preferably 3D three-dimensional spiral eccentric fiber-made flow guiding non-woven fabric, and the flow guiding non-woven fabric is fluffy, high in elasticity, capable of realizing omnibearing spiral penetration, and capable of effectively controlling and reducing reverse penetration. It is effective in helping the liquid to rapidly transfer inwardly from the surface contact layer 1 and to distribute the liquid in a longitudinally spreading manner so that the liquid quickly leaves the skin of the user and enters the absorbent core layer 3. The dryness of the surface contact layer 1 can be ensured, and the use comfort is improved.

The absorption core layer 3 is of a wood pulp structure or a composite core body structure, 10-70% of high-molecular water-absorbent resin is added in the middle, and the absorption speed and the rewet capacity of the absorption core layer are optimal through reasonable proportioning. The wood pulp structure is produced by crushing wood pulp into fluff pulp on a production line. The composite core body is made of pre-made absorbent paper, can be three layers or five layers, and can be directly used on a machine. The composite core body can be glued or heat-sealed. The composite core may have a variety of configurations, such as: wet strength paper, polymer, wet strength paper and glue; lining paper, polymer, dust-free paper and wood pulp; dust-free paper, SAP, fluffy non-woven fabric, SAP, glue, dust-free paper and the like.

The bottom coating 7 is preferably a breathable PE film, and the air permeability of the product is improved by adopting a casting or film blowing process. The air-permeable PE film is a water-impermeable material and can retain excreta such as menstrual blood in the absorbent core layer 3.

The absorption core layer 3 is bonded with the surface contact layer 1 and the bottom cladding layer 7 through non-crossed omega-shaped spray glue 8, and the diversion layer 2 is wrapped inside. The non-crossed omega-shaped glue spraying 8 has the advantages that the liquid diffusion length on the diversion layer is increased compared with the traditional spiral glue spraying mode, the glue spraying is uniform, and the bonding strength is high.

The bottom of the bottom cladding 7 is correspondingly provided with an adhesive (not shown in the figures). When the sanitary towel is not used, the release paper is connected with the bonding part. When the sanitary towel is replaced, the release paper is torn off, and the anti-seepage basement membrane is adhered to the clothes through the adhering part.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still belong to the protection scope of the present invention.
