Absorbent article with super air permeability

Abstract

The invention relates to an absorbent article with super air permeability. In order to enable the existing absorbent article to achieve the effect of ventilation without liquid leakage or urine leakage, the absorbent article is characterized in that one or more first through hole(s) passing through the absorbent article along the thickness direction is / are formed in the absorbent article, so that the moisture in a closed space formed by the absorbent article and the body surface of a user can be rapidly discharged outside the closed space. In order to prevent sewage liquid from leaking outside through the first through hole(s), the absorbent article also comprises one or combination of more in a leakage prevention absorber, a ring hole thickening leakage prevention structure, a liquid absorption expansion liquid blocking dam, a diversion trench and the like which are used for preventing the body fluid from leaking outside through the first through hole(s). The air permeability of the absorbent article can be improved by another alternative or auxiliary characteristic, namely, the absorbent article comprises one or more selective ventilation structure(s).

Description

technical field [0001] The object of the present invention is to provide a super-breathable absorbent article, especially women's hygiene products (such as sanitary napkins), infant diapers, diapers, pull-up pants, adult care products, and pet and other animal care products Wait. Background technique [0002] With the improvement of living standards and science and technology, sanitary napkins, paper diapers and other absorbent articles have been widely used. Although the advent of modern absorbent articles has greatly facilitated the nursing work, no matter how strong the absorbent article's liquid absorption and liquid retention capabilities are, body fluids such as urine are always immersed in its interior. Limited by the structure and performance of leak-proof materials, such absorbent articles have disadvantages such as poor air permeability, which is not conducive to keeping the internal environment dry, and can easily cause many problems such as diaper rash, dermatit...

AI Technical Summary

Problems solved by technology

The air permeability of this kind of diaper depends to a large extent on the air permeability of the material used in the diaper itself, and the material with good air permeability has poor anti-leakage ability, and most of the general materials have poor air permeability in wet state. Ideal, it makes the body parts wrapped in diapers airtight, and it is easy to make the surrounding environment of the skin in this part humid and hot, causing allergies, diaper rash and other problems under the action of urine
