Problems solved by technology

[0002] At present, sanitary napkin products on the market generally use three-piece or three-dimensional guards to prevent side leakage on the use surface of the sanitary napkin, but products with this design still have a certain proportion of side leakage in actual use, and the absorbent body of the sanitary napkin is After absorbing menstrual blood and other liquids, it is easy to cause the liquid to leak from the absorbent body due to the extrusion of the human body. Since the top of the wings on both sides is generally made of water-repellent hot air or water-repellent spunbonded non-woven fabrics, this kind of non-woven fabrics Most of the water pressure resistance is lower than 25bar, which is lower than the 30ba load pressure of the general human body. Therefore, the seeping liquid will overflow from the non-woven wings on both sides of the absorber to the surface of the sanitary napkin, thereby contaminating the underwear and causing serious harm to consumers. causing inconvenience and negative physical and mental effects

Embodiment 1

[0024] refer to figure 1 and figure 2 , an anti-side leakage sanitary napkin, comprising a main body of the sanitary napkin, the main body of the sanitary napkin is composed of a fabric layer 1, a diversion layer 2, a bottom film 3 and a back release paper 4 from top to bottom, and the layers are arranged between Coated with structural glue, it is firmly pasted and has a certain breathable effect.

[0025] An absorber wrapping layer 5 is arranged between the flow guide layer 2 and the bottom film 3, and the absorber wrapping layer 5 includes an absorber core 6, an absorber surface layer that fully covers the absorber core 6 7 and the anti-side leakage layer 8 coated on the outside of the absorber surface layer 7, the folded sealing part of the absorber surface layer is sealed by structural glue, even if the absorbent core 6 is squeezed and leaked liquid will be prevented The side leakage layer 8 is blocked so that it cannot overflow the surface of the sanitary napkin, so th...

Embodiment 2

[0032] refer to image 3 and Figure 4 , an anti-side leakage sanitary napkin, comprising a sanitary napkin main body, the sanitary napkin main body is composed of a fabric layer 1, a diversion layer 2, a bottom film 3 and a back release paper 4 from top to bottom, and the diversion layer 2 and the base film 3 are provided with an absorber wrapping layer 5, and the absorber wrapping layer 5 includes an absorbent core 6, an absorber surface layer 7 that fully covers the absorbent core 6, and covers the The anti-side leakage layer 8 outside the surface layer 7 of the absorber.

[0033] The side leakage prevention layer 8 covers the lower surface and the left and right sides of the absorber surface layer 7, and the left and right ends of the side leakage prevention layer 8 are adhered to the upper surface of the absorber surface layer 7 by structural glue, Both ends of the lower surface of the absorber surface layer 7 are adhered to the anti-side leakage layer 8 through structu...

Abstract

The invention discloses a side-leakage-prevented sanitary napkin. The side-leakage-prevented sanitary napkin comprises a sanitary napkin main body, wherein the sanitary napkin main body is composed ofa shell fabric layer, a diversion layer, a basilar film and back release paper sequentially from top to bottom, and an absorber coating layer is arranged between the diversion layer and the basilar film and comprises an absorption core, an absorber surface layer fully coating the absorption core and a side-leakage-preventing layer coating the absorber surface layer. Even if the absorption core isextruded, seeping liquid will be blocked off by the side-leakage-preventing layer and cannot overflow from the surface of the sanitary napkin, so that the autologous side leakage preventing performance of the sanitary napkin is improved greatly under the condition of not lowering absorbing capacity of the absorption core, and inconvenience and discomfort to a consumer caused by a side leakage phenomenon of the sanitary napkin are avoided.
