Description

Technical Field

[0001] The utility model relates to the technical field of diapers, in particular to a water-absorbent sanitary napkin. Background Art

[0002] Sanitary napkins are absorbent materials. Their main materials are high molecular polymers and high molecular polymer composite paper formed by composites of cotton, non-woven fabrics, pulp or the above materials. The side design is mainly used to prevent side leakage. Because it will be at a certain angle to the sanitary napkin body when used, it is more likely to cause friction with the groin. Therefore, sanitary napkins with sides made of soft materials are more popular among women. The adhesive on the back of the sanitary napkin is made of waterproof material, which can retain the menstrual blood in the sanitary napkin and is used to absorb the menstrual blood flowing out of the vagina during menstruation.

[0003] However, in the prior art, in order to increase its water absorption, the absorbent core inside the sanitary napkin is generally made thicker, which makes the air permeability of the sanitary napkin not very good, so it is necessary to make improvements. Summary of the invention

[0007] In some embodiments, the absorbent core is provided with arc-shaped grooves on both sides of the arc-shaped protrusion.

[0008] In some embodiments, the guide groove is provided with an absorption hole at one end of the bottom of the arc-shaped protrusion.

[0009] In some embodiments, there are no less than 10 guide grooves.

[0010] In some embodiments, a high water-absorbing molecular layer is disposed in the middle of the absorption layer.

[0011] In some embodiments, wings are provided on both sides of the sanitary napkin body.

[0012] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model allows air to enter the guide groove through the gaps in the place where the guide groove contacts the skin to maintain a good ventilation effect, which will not make it so stuffy; at the same time, the arc-shaped protrusion is tightly attached to the private part, which can improve the absorption efficiency and prevent the risk of side leakage.
