Problems solved by technology

The processing performance and edge sealing performance of the non-woven fabric layer are better, but because it is a chemical fiber product, its water permeability is poor; especially the menstrual blood discharged during the menstrual period has a high viscosity, if it passes through the non-woven fabric layer completely It takes a long time to penetrate the absorbent core layer, menstrual blood that cannot penetrate the absorbent core layer quickly will cause friction with the skin, women will feel very uncomfortable, especially when walking, it will bring great troubles to women

Embodiment 1

[0016] A sanitary napkin with liquid guiding holes, comprising a PE film bottom layer, an absorbent core layer and a non-woven fabric layer 1; the absorbent core layer is located between the PE film bottom layer and the non-woven fabric layer 1.

[0017] Such as figure 1 , 2 As shown, the surface of the non-woven fabric layer 1 is provided with a plurality of flow guide holes 2 connected to the absorbent core layer.

[0018] Such as image 3 As shown, the diameter of the upper opening of the diversion hole 2 is larger than the diameter of the lower opening; preferably, the diameter of the upper opening of the diversion hole 2 is twice the diameter of the lower opening. According to the characteristics of women's menstrual period, it is known that the menstrual secretion includes some viscous substances, such as the menstrual blood accompanied by the collapse and shedding of the endometrium. The diameter range of the opening is 1-3mm, and the diameter of the lower opening is...

Abstract

The invention discloses a sanitary napkin with liquid guide holes. The sanitary napkin comprises a PE (poly ethylene) film bottom layer, an absorption core layer and a non-woven fabric layer, wherein the absorption core layer is positioned between the PE film bottom layer and the non-woven fabric layer; a plurality of liquid guide holes communicated with the absorption core layer are formed in the surface of the non-woven fabric layer; the diameter of the upper opening of each liquid guide hole is greater than that of the lower opening of each liquid guide hole. Compared with the prior art, the plurality of liquid guide holes are adopted to be formed in the non-woven fabric layer, and enable menstrual blood to penetrate into the absorption core layer quickly through the non-woven fabric layer, so that the technical problems about easiness in menstrual blood leakage and contact of menstrual blood with skin due to poor penetrability of the non-woven fabric layer in the prior art are solved, and safety and comfort of human bodies are improved.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a sanitary napkin with liquid guiding holes. Background technique [0002] The bottom layer of commercially available sanitary napkin products is generally PE film, the middle layer is the absorbent core layer, and the surface layer is mostly made of non-woven fabric. The processing performance and edge sealing performance of the non-woven fabric layer are better, but because it is a chemical fiber product, its water permeability is poor; especially the menstrual blood discharged during the menstrual period has a high viscosity, if it passes through the non-woven fabric layer completely It takes a long time to penetrate into the absorbent core layer, and the menstrual blood that cannot penetrate into the absorbent core layer quickly will cause friction with the skin, and women will feel very uncomfortable, especially in the walking state, which will bring great troubles...
