Absorptive article with super air permeability

Abstract

An absorbent article having super air permeability comprises a liquid-permeable top layer (2), a liquid-permeable or liquid-impermeable bottom layer (1) and a liquid-absorbent, liquid-retaining layer (3) disposed between said top layer (2) and bottom layer (1). In order to make the absorbent article achieve air-permeability without liquid leakage or urine leakage, the absorbent article comprises one or a plurality of first through-holes (10) and at least one leakage-prevention structure corresponding to the first through-holes (10). The first through-holes (10) penetrate the absorbent article in the thickness direction thereof from the top layer (2) to the bottom layer (1), thus accelerating outward discharge of humidity from the enclosed space formed between the absorbent article and the body surface of the user. The leakage-prevention structure can be chosen from among: a leakage-preventing absorbent body (11), a thickened ring structure surrounding the holes, a liquids-blocking material that expands when absorbing liquids (12), flow-guide channels (13) and any combination of these in order to prevent leakage from the through-holes (10) of contaminated liquids. The air-permeability of the absorbent article can also be increased by the introduction of other substitute or auxiliary optional permeable structures (19).

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
