The absorbent body of conventional sanitary napkins has two main forms: the absorbent body is a wood pulp structure absorbent body, and the absorbent paper structure absorbent body is a water-absorbing paper structure absorbent body. The wood pulp structure absorber sanitary towel is formed by bonding a surface layer non-woven fabric, fluff pulp, a high polymer material layer and a bottom film from top to bottom, but is easy to deform and delaminate after absorbing liquid due to softer core body; meanwhile, the fluff pulp core is thicker, and particularly, the fluff pulp is easy to smolder and airtight in summer, so that bacteria are bred. The absorbent sanitary towel with the absorbent paper structure consists of surface layer non-woven fabric, dust-free paper, absorbent paper containing high polymer and bottom film. This type of absorbent body, while thinner than wood pulp cores, is relatively stiff and thin, and is prone to side leakage and back leakage during use, and is unsafe to use.
In recent years, a sanitary towel absorbent core formed by liquid materials has appeared, and unlike the traditional absorbent, the sanitary towel adopting the novel absorbent core is thinner, softer and more closely fitted than the common sanitary towel, and is formed by integrally forming the liquid material layer by purified water and nano molecular polymer and adopting a high-pressure liquid phase emulsion polymerization technology, and the surface of the liquid material layer is clean and soft, thereby realizing three-dimensional quick absorption. However, the strength of the liquid material layer is low, and the core body is easy to curl, deform and delaminate after absorbing liquid, so that the using feel is affected; meanwhile, the liquid absorption capacity of the liquid material layer is limited (the absorption capacity is 10 times of the self weight), and the problem that the liquid is easy to reversely permeate to the surface of a product after being absorbed is solved by extrusion.
Therefore, how to solve the problems that the sanitary towel using the liquid material layer as the absorber is easy to reverse osmosis and the absorber is easy to curl, deform and delaminate is a problem to be solved.

Aiming at the problems existing in the prior art, the utility model aims to provide a novel liquid absorption core sanitary towel, solves the problems that the existing liquid sanitary towel is easy to cause liquid reverse osmosis and side leakage after being used for a period of time, and improves the liquid absorption capacity and the liquid locking capacity of the sanitary towel by additionally arranging a non-woven fabric layer and a composite water absorption paper layer below a liquid material layer, thereby effectively avoiding the reverse osmosis phenomenon of the sanitary towel after absorbing liquid.
The utility model aims at realizing the following technical scheme:
the novel liquid absorption core sanitary towel comprises a sanitary towel body and side wings, wherein the sanitary towel body sequentially comprises a surface layer, an absorption core and a bottom film from top to bottom, and the absorption core is formed by compounding a liquid material layer, a non-woven fabric layer and a composite water absorption paper layer; the side wings are of a double-layer structure, the upper layer is water-repellent cloth, the lower layer is a bottom film, and the water-repellent cloth and the bottom film are pressed and compounded; the upper water-repellent cloth of the protective wings at both sides extends to the middle sanitary towel body and forms a water-repellent flange to cover the sanitary towel body.
Further, a plurality of funnel-shaped liquid collecting holes are uniformly distributed on the liquid material layer.
Further, the total thickness of the absorbent core is 4.0mm to 6.0mm, wherein the thickness of the liquid material layer is 2.0mm to 4.0mm.
Further, the length and width of the liquid material layer are smaller than those of the non-woven fabric layer below the liquid material layer.
Further, the top layer, the absorbent core and the bottom film are formed by hot melt adhesive compression molding.
Further, the water-repellent cloth is made of soft hot air material.
Further, the bottom film is made of a breathable film and a non-woven fabric in a compounding mode.
Further, the surface layer is made of a hydrophilic super-soft superfine fiber material.
Compared with the prior art, the utility model has the beneficial effects that:
in the novel liquid absorption core sanitary towel, the non-woven fabric layer and the composite water absorption paper layer are additionally arranged below the liquid material layer, wherein the non-woven fabric layer effectively strengthens the strength of the absorption core, ensures that the liquid material layer is not easy to deform and delaminate after absorbing liquid in the use process of the sanitary towel, and simultaneously enhances the flexibility of the absorption core; because the liquid absorption capacity of the liquid material layer is lower, the liquid material layer is only used as the absorption core body of the sanitary towel, and the phenomena of reverse osmosis of menstrual blood, side leakage and back leakage are easy to occur.
