Sanitary towel with hidden permeability function

Abstract

The invention provides a sanitary towel with a hidden permeability function. The sanitary towel comprises a face layer, a middle core layer and a bottom membrane layer, the middle core layer comprises a diversion drying layer close to one side of the face layer and an absorption layer away from one side of the face layer, expansion small balls are arranged at the side, close to the face layer, of the drying layer, a liquid-resisting breathable layer is arranged at the portion, opposite to the diversion drying layer, of the face layer, a flow passing hole is formed in the liquid-resisting breathable layer, the drying and breathable capability of the sanitary towel can be improved, the comfort of a user is improved, and bacterium breeding and infection are reduced.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a sanitary napkin with hidden penetration function. Background technique [0002] The sanitary napkins provided on the existing market use materials such as non-woven fabrics or plastic perforated films as the surface layer. Below the surface layer is an absorbent layer or absorbent sheet material. Some technologies divide the absorbent layer into convex The absorbent layer and the absorbent layer are two parts, the absorbent layer and the absorbent sheet material are used to absorb liquid and store liquid. The performance of this surface layer and the combined structure of the surface layer, the absorbent layer and the absorbent sheet material cannot make the surface of the sanitary napkin more dry and breathable, especially in hot summer, and sanitary napkins with poor air permeability and dryness will feel uncomfortable. The genitals are humid, stuffy, very uncomfor...

AI Technical Summary

Problems solved by technology

The performance of this surface layer and the combined structure of the surface layer, the absorbent layer and the absorbent sheet material cannot make the surface of the sanitary napkin more dry and breathable, especially in hot summer, and sanitary napkins with poor air permeability and dryness will feel uncomfortable. The genitals are humid, stuffy, very uncomfortable, and will accelerate the growth of various bacteria, causing gynecological diseases

The absorbent layer of the sanitary napkin absorbs liquid, especially after a relatively large amount of liquid, it is difficult to keep dry and hygienic

[0003] In addition, after the sanitary napkins on the market absorb the liquid, the liquid will accumulate more or less on the surface layer. Since the liquid has color, it will lose its original pure color when it is stained on the surface layer of the sanitary napkin. Creates visual pollution that can have a negative impact on the user after use or on others after disposal
