Diaper capable of preventing urine leakage and excrement leakage with good air permeability

Abstract

The invention relates to the field of nursing materials, in particular to a diaper capable of preventing urine leakage and excrement leakage with good air permeability, which comprises a diaper body and a urine blocking layer arranged on the peripheral edge of the diaper, the diaper body comprises a liquid-permeable surface thin layer, a liquid-impermeable back thin layer and a liquid-absorbing core layer arranged between the liquid-permeable surface thin layer and the liquid-impermeable back thin layer, the liquid-impermeable back thin layer is made of GORE-TEX fabric, the water-absorbing core layer is longitudinally divided into a plurality of interlayers during sewing, wherein the density of the water-absorbing polymer resin laid in the front B area of the diaper core body for the female or the baby girl is twice that of other areas; the density of the water-absorbing polymer resin laid in the back A area of the diaper core body for the male or the baby boy is twice that of other areas, and a rubber strip is adhered to the middle of the outer side of the liquid-impermeable back thin layer through a hook-and-loop fastener. The diaper provided by the invention has good air permeability and capable of preventing urine leakage and excrement leakage.

Description

technical field [0001] The invention relates to the field of nursing products, in particular to a diaper with good air permeability that prevents leakage of urine and stool. Background technique [0002] As a necessary daily necessities for babies, diapers accompany babies almost all day long. At present, commercially available diapers have the following defects: [0003] 1) The main wet part of the male baby is the front part of the diaper, while the back part is almost dry, while the main wet part of the female baby is the rear part, and the front part is almost dry, but currently commercially available diapers are common The design of laying the same density of water-absorbing polymer resin on the front and back is poor in pertinence; [0004] 2) After the front part of the diaper is mainly wet for male babies, the front part instantly absorbs water and the volume increases and becomes thicker, oppressing the male baby's genitals, which may affect the development of the...

AI Technical Summary

Problems solved by technology

[0003] 1) The main wet part of male babies is the front part of the diaper, while the back part is almost dry, while the main wet part of female babies is the back part, and the front part is almost dry, but currently commercially available diapers are common The design of laying the same density of water-absorbing polymer resin on the front and back is poor in pertinence;

[0004] 2) After the front part of the diaper is mainly wet for male babies, the front part will instantly absorb water and increase in volume and thickness, which will compress the male baby's genitals and may affect the development of male baby's genitals;

[0005] 3) Babies with a lot of stool will often squeeze out from the waist behind the diaper after defecating, dirtying the baby's clothes;

[0006] 4) The waists on both sides bonded by the front and back ends of the diaper are generally thin, and there is no water-absorbing core layer. When the baby sleeps on the side at night, urine will leak from the side abdomen or side waist, which will wet the baby's clothes and bed sheets. Tossing babies can't sleep well, especially male babies, because the gap between their genitals and diapers is too small, which makes it impossible to catheterize at a uniform speed, which is more likely to cause side leakage;

The waterproof and air permeability of PE plastic film can be explained by the microporous moisture permeability mechanism and the diffusion theory based on pressure difference, that is, when the micropore size of PE plastic film is between the diameter of liquid molecules and the diameter of air molecules, it can effectively block liquid leakage And transmit a small amount of air, but the air penetration rate is very slow, so the speed of heat and humidity passing through the PE plastic film is very slow, so people will feel it when they use the diaper with the PE plastic film as the waterproof bottom film. Humid and hot and extremely uncomfortable, even serious health problems such as red buttocks can occur
