[0029] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example

[0030] like Figures 1 to 3 As shown, a side leakage prevention sanitary napkin comprises a sanitary napkin body 1, wherein the sanitary napkin body 1 comprises a skin-friendly layer 2, a guide layer 3, a water-absorbing layer 4 and a leak-proof layer 5 which are stacked from top to bottom, wherein the edges of the skin-friendly layer 2, the guide layer 3 and the leak-proof layer 5 are connected by hot pressing, wherein a covering layer 6 is arranged below the sanitary napkin body 1, wherein the covering layer 6 extends to both sides of the sanitary napkin body 1 to form fixed wings 7, wherein an absorbent strip 11 is sandwiched in the sanitary napkin body 1, wherein the absorbent strip 11 is arranged at both sides of the sanitary napkin body 1, wherein the absorbent strip 11 is prefabricated and then glued to the sanitary napkin body 1, wherein the absorbent strip 11 is arranged at the hot pressing edge of each structural layer, and wherein the absorbent strip 11 adopts a film-like SAP;

[0031] The skin-friendly layer 2 is made of antibacterial pure cotton non-woven fabric, the guide layer 3 is made of ES fiber hot air cloth, the water-absorbing layer 4 is made of dust-free paper wrapped with high molecular water-absorbing resin, the leak-proof layer 5 is made of PE film, and the covering layer 6 is made of pure cotton spunlace non-woven fabric;

[0032] By sandwiching an absorbent strip in the sanitary napkin body 1, the structural layers on both sides of the sanitary napkin body 1 include the structural layers of the sanitary napkin body 1 and the absorbent strip 11, so as to increase the absorption amount of the sanitary napkin body 1 to the side flow liquid, and the absorbent strip 11 is arranged at the pressing part to avoid excessive protrusion and causing foreign body sensation; through the prefabricated absorbent strip 11, its production line is separated from the production line of the sanitary napkin body 1, and the production of the absorbent strip 1 requires relevant solution reagents, etc., while the production of the sanitary napkin body 1 needs to be under dry and sterile conditions, and different production workshops are distinguished, which is conducive to controlling the different production environment conditions of the two production lines;

[0033] The absorption strip 11 is arranged between the water absorption layer 4 and the guide layer 3. The absorption strip 11 has a width of 2-3 cm and a thickness of 2-5 mm. The film-like SAP can be a film-like polymer water-absorbing resin described in Chinese Patent Publication No. CN113637113B, which is a well-known material and will not be described in detail here.

[0034] The absorbent strip 11 is in the shape of a long strip, and both ends of the absorbent strip 11 extend to the edge of the sanitary napkin body 1. The edges of both ends of the absorbent strip 11 are consistent with the edges of the sanitary napkin body 1, and can fully seal both sides of the sanitary napkin body to prevent side leakage;

[0035] The lower surface of the covering layer 6 is provided with a pressing line 61, and the pressing line 61 is closed at both ends. The pressing line 61 is formed by a plurality of pressing points at intervals. The pressing line 61 formed by the pressing points facilitates the diffusion of liquid in the sanitary napkin body 1, so that the pressing line 61 does not play an obstructive role. The pressing lines 61 arranged along the length direction of the sanitary napkin body 1 are close to each other, which is conducive to the bending and deformation of the sanitary napkin body 1 when it is clamped on the trouser body. Since the edges of the skin-friendly layer 2, the guide layer 3 and the leak-proof layer 5 are connected by hot pressing, in order to ensure that the water-absorbing layer 4 will not deviate during use, the pressing line 61 presses the covering layer 6, the leak-proof layer 5 and the water-absorbing layer 4 together;

[0036] Two pairs of longitudinal guide grooves 12 and two pairs of transverse guide grooves 13 are arranged at intervals on the top of the sanitary napkin body 1. Each of the longitudinal guide grooves 12 is arranged along the length direction of the sanitary napkin body 1, and each of the transverse guide grooves 13 is arranged along the width direction of the sanitary napkin body 1. The inner pair of longitudinal guide grooves 12 and the outer pair of transverse guide grooves 13 are connected to each other to form a closed guide groove 14. Each of the longitudinal guide grooves 12 and the transverse guide grooves 13 are arc-shaped.

[0037] The setting of the guide groove facilitates the liquid to diffuse along the guide groove to both sides of the fluid direction when it flows to the guide groove position, so as to achieve the purpose of guiding. Multiple pairs of guide grooves arranged at intervals can buffer the flow rate of the liquid so as to better absorb the liquid. Since the longitudinal guide groove 12 is arranged along the length direction of the sanitary napkin body, when the sanitary napkin is fixed to the underwear, the longitudinal guide groove 12 facilitates better bending of both sides of the sanitary napkin. If a closed guide groove 14 formed by a pair of longitudinal guide grooves 12 arranged outside is used, since the longitudinal guide groove 12 on the inner side has a limited length, it is easier to bend at the longitudinal guide groove 12 arranged outside, and folds will be formed at both ends of the longitudinal guide groove 12 on the inner side, which is uncomfortable to wear.

[0038] For the transverse guide groove 13, the closed guide groove 14 formed by the transverse guide groove 13 arranged outside is adopted. After the liquid diffuses along the transverse guide groove 13 arranged inside, it will continue to diffuse along the length direction of the sanitary napkin body 1, and the flow blocking effect is small, which can improve the utilization rate of the sanitary napkin and facilitate dispersed absorption;

[0039] During production, after the water-absorbing layer 4, the leak-proof layer 5 and the covering layer 6 are glued together, the pressing line 61 is set, and then the guide layer 3 and the skin-friendly layer 2 are covered, and the skin-friendly layer 2, the guide layer 3 and the leak-proof layer 5 edges are hot-pressed and connected, and then the guide groove is set.

[0040] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
