The present invention relates to an absorbent structure having improved breathability, and more particularly, to an absorbent structure having improved breathability, which can quickly absorb secretions and shorten drying time, thereby improving wearer's hygiene.

In general, a disposable absorbent product is a generic term for a product that absorbs secretions and excretion secreted, excreted by human physiology, and has a comprehensive meaning of diapers, training pants, sanitary napkins, panty liners, and the like.

Disposable diapers, in particular, are mainly used to absorb urine in infants by being made of absorbent material between the skin contact endothelial with good absorbency and wearing comfort and the high frequency welded outer skin to prevent leakage.

Recently, the disposable panty diaper has been widely used due to its convenience, and the diaper structure has been diversified in response to this.

Diapers are usually in close contact with the skin and are usually worn for 3 to 5 hours, so when used with sensitive and sensitive skin, feces such as urine should be absorbed quickly and feces should be acceptable without leakage.

For this reason, the conventional disposable diapers have been developed with emphasis on absorbency only, so that the ventilation is poor and no sweat band is generated or rapid drying is always kept moist.

In addition, the excellent absorbency, even if the liquid excretion is quickly absorbed because the moisture in contact with the absorbent is always in contact with the endothelial at the time of absorption, not only to dry the skin is also always kept wet until you change diapers.

Moreover, the ammonia produced when the protein components in the excreta are broken down damages the skin barrier, an acid protective barrier that prevents the invasion of bacteria, thereby weakening the skin.

As a result, various skin diseases such as urticaria, diaper rash, sweat band, etc. are frequently generated due to penetration of the bacteria from the skin friction and excretion caused by excessive movements such as hives.

The top sheet 110 is located on the top side and in direct contact with the skin of the wearer when worn, it is provided in a plate shape having a predetermined area, discharge or discharge from the wearer (hereinafter referred to as 'secretion'). ) Does not leak to the outside.

The upper sheet 110 is provided to have a liquid permeability to pass the liquid secretion, such as water discharged from the urine or solid secretions, but does not pass the solid secretions such as feces.

In addition, the upper sheet 110 is preferably made of a cotton fabric so as to make a direct contact with the skin of the wearer to increase the wearer's wearing comfort and to smoothly move the liquid secretion to the absorber 120 side.

At this time, the lower surface of the top sheet 110 may be provided with a material 160 having an acid, as shown in FIG. This is to prevent the wearer's skin from being weakened or damaged by neutralizing the basic material generated in the process of decomposing the secretion into the acidic material 160.

In other words, all the urine, feces or secretions discharged from the human body will contain a protein, and when such a protein is broken down, basic ammonia is generated.

When such ammonia comes into contact with the skin of the human body, it damages the skin barrier, which is an acid protective film that prevents the invasion of bacteria, thereby weakening the skin and facilitating the penetration of various bacteria, thereby causing various skin diseases.

In particular, the elderly and infants with weak skin are frequently infected with infiltrated bacteria and skin diseases such as diaper rash frequently occur.

In the present invention, the acidic material 160 is provided on the lower surface of the upper sheet 110 so as to neutralize and remove the basic material generated during the decomposition process of the secretion, thereby preventing damage to the skin by the basic material and acidic. It is to prevent the infection and proliferation of bacteria.

Such an acidic substance can be used as long as it is an acidic substance, but it is preferable to use alum or vinegar made of a natural material, which is harmless to the human body, and it is more preferable to use alum with a colorless odor.

However, the acidic material 160 used in the present invention is not limited to alum, and as mentioned above, the acidic material 160 is known to be sufficient as long as it has an acidic material.

The acidic material is applied to the lower surface of the top sheet 110 by applying an adhesive to the lower surface of the top sheet 110, and then sprayed with an acidic material formed into small grains to be adhered thereto.

The absorber 120 is disposed between the upper sheet 110 and the lower sheet 140 to absorb the liquid secretion or water passing through the upper sheet 110, which is commonly used in absorbent products Phosphorus absorbers are used.

However, the absorber 120 of the present invention is provided with a plurality of cubes of a circular or polygonal shape having a certain height as shown in Figures 1 to 4, the neighboring absorbers 120 are arranged to be spaced apart from each other There are technical features of the present invention.
