[0030] The preferred embodiments of the present application are described below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0031] It should be noted that these drawings are simplified schematic diagrams, and only schematically show the basic structure of the present application, and therefore only show the relevant components of the present application.

[0032] Referring to Figures 1 to 5 The present application discloses a sanitary napkin based on a woven structure, comprising: a surface layer 1, a core layer 20 and a bottom layer 3 arranged in sequence from top to bottom, the core layer 20 comprising a reverse osmosis membrane layer 21 and a breathable waterproof membrane layer 22 arranged below the reverse osmosis membrane layer 21, the reverse osmosis membrane layer 21 can effectively reduce the back seepage of menstrual blood, and improve the use comfort of the sanitary napkin, the breathable waterproof membrane layer 22 has good breathability and waterproofness, and the sanitary napkin can neither leak menstrual blood nor keep the gas flowing during use, and two woven edge strips 23 are connected between the reverse osmosis membrane layer 21 and the breathable waterproof membrane layer 22, the woven edge strips 23 are composed of woven cloth, fluff pulp and absorbent resin material; the menstrual blood that overflows can be quickly absorbed, and the risk of side leakage is reduced.

[0033] The liquid absorption layer 24 is connected between the woven edge strips 23, and the let-position cavity 25 is arranged between the liquid absorption layer 24 and the breathable waterproof membrane layer 22; the binding force of the underpants drives the bottom layer 3 to deform, and due to the existence of the let-position cavity 25, the bottom layer 3 will not directly drive the surface layer 1 to be in close contact with the skin within a certain deformation range.

[0034] The liquid absorption layer 24 comprises a dust-free paper layer 241, a plurality of fixed hole members 242 are arranged on the dust-free paper layer 241 in a spaced manner, the fixed hole members 242 comprise a plurality of rectangular holes 2421 arranged in a spaced manner, and the liquid absorption layer 24 further comprises a plurality of water absorption paper strips 243 equal in number to the fixed hole members 242, the water absorption paper strips 243 pass through the rectangular holes 2421 of the fixed hole members 242 in a wave shape in sequence; the width of the inner cavity of the rectangular hole 2421 is greater than the width of the water absorption paper strip 243 by 0.2-0.5 mm; so that there is a gap between the water absorption paper strip 243 and the inner wall of the rectangular hole 2421, and the breathability is enhanced.

[0035] The upper and lower surfaces of the water absorption paper strip 243 are coated with a high-molecular water absorption resin layer 4 respectively; the water absorption paper strip 243 and the high-molecular water absorption resin layer 4 both have strong liquid absorption performance, thereby increasing the amount of menstrual blood absorbed by the sanitary napkin and improving the use effect.

[0036] The upper surface of the breathable waterproof membrane layer 22 is coated with an ultra-fine calcium powder layer 5; the ultra-fine calcium powder layer 5 has strong adsorption performance and antibacterial performance, can remove the odor generated by menstrual blood, and has strong inhibition function on bacteria, which is beneficial to the health of the human body.

[0037] The thickness of the accommodation cavity 25 is one third of the thickness of the woven edge strip 23; the reduced binding force of the underpants drives the sanitary napkin into close contact with the skin of the human body.

[0038] The implementation principle of the embodiment is that, in use, the sanitary napkin is connected to the inner surface of the underpants, and the use of the surface layer 1 enhances the comfort of the sanitary napkin in contact with the skin, and the menstrual blood that has passed through the reverse osmosis membrane layer 21 of the core layer 20 is absorbed by the liquid absorption layer 24; since the liquid absorption layer 24 is composed of the dust-free paper layer 241 and the water absorption paper strip 243, the water absorption paper strip 243 can absorb the menstrual blood in a short time, and since the dust-free paper layer 241 has good flow guiding performance, a part of the menstrual blood can be guided to the water absorption paper strip 243 that is not in contact with the skin, so that all of the water absorption paper strip 243 can quickly absorb the menstrual blood, reducing the probability of side leakage and improving the use effect; the accommodation cavity 25 is arranged to prevent the binding force of the underpants from driving the sanitary napkin into close contact with the skin, improving the comfort of use; the use of the woven edge strip 23 enables the two side edges of the sanitary napkin to have good contact with the skin, reducing the probability of side leakage and improving the use effect.

[0039] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
