All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a double-layer absorption structure for sanitary towels and menstrual pants, and aims to solve the problems of poor air permeability and poor absorption of the conventional sanitary towels and menstrual pants.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example 1:

the embodiment provides a double-layer absorption structure for sanitary towels and menstrual pants, which comprises a surface layer 2, wherein two ends of the surface layer 2 are connected with lateral leakage prevention layers 1, a flow guide layer 3 is arranged below the surface layer 2, an upper absorption body is arranged below the flow guide layer 3, a middle layer 5 is arranged below the upper absorption body, a lower absorption body is arranged below the middle layer 5, and a bottom layer 9 is arranged below the lower absorption body, as shown in figure 1.

Specifically, the surface layer 2, the side leakage prevention layer 1 and the flow guide layer 3 are all made of nonwoven fabric layers.

Further, the upper absorber comprises a wood pulp layer 4 positioned below the flow guide layer 3, the wood pulp layer 4 can play a role in instantaneous absorption, an upper macromolecule layer 6 is arranged below the wood pulp layer 4, the upper macromolecule layer 6 can absorb and lock menstrual blood, and the upper macromolecule layer 6 is positioned above the middle layer 5.

Further, the lower absorber comprises a lower polymer layer 7 positioned below the middle layer 5, the lower polymer layer 7 is further absorbed and locked with menstrual blood, a puffed paper layer 8 is arranged below the lower polymer layer 7, the puffed paper layer 8 can also play a role in instant absorption and diversion, and the puffed paper layer 8 is positioned above the bottom layer 9.

Further, the content of the high water-absorbent resin in the upper polymer layer 6 and the lower polymer layer 7 is more than 2g, and the absorption amount is secured.

Further, the middle layer 5 and the bottom layer 9 both adopt SMS water-repellent non-woven fabric layers which have good air permeability and can block the leakage of menstrual blood.

Furthermore, the hydrostatic pressure resistance of the middle layer 5 is more than 2KPa, and the middle layer is not easy to damage.

The double-layer absorption structure for the sanitary towel and the menstrual pants can be quickly infiltrated when menstrual blood contacts the surface layer 2, the side leakage prevention layer 1 can effectively prevent side leakage, the infiltrated menstrual blood is guided by the flow guide layer 3 and then enters the wood pulp layer 4 and the upper molecular layer 6 to be absorbed and locked, if the menstrual blood amount is too large, the middle layer 5 can possibly damage the middle layer 5 under the wetting and pressure of the menstrual blood to cause the downward leakage of the menstrual blood, at the moment, the lower molecular layer 7 and the swelling paper 8 can effectively absorb the menstrual blood, and the bottom layer 9 can prevent the outward infiltration of the menstrual blood and has a good ventilation effect.

The principle and the implementation mode of the invention are explained by applying specific examples, and the description of the above examples is only used for helping understanding the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
