The present invention relates to a disposable diaper, and more particularly, to a disposable diaper which minimizes skin irritation by manufacturing or coating a contact surface of a coagulation band which is installed to prevent the excretion from leaking sideways in a disposable diaper with a super absorbent fabric. .

In recent years, as the use of disposable diapers has increased rapidly, many studies have been conducted in order to improve absorbency, which is a primary function of disposable diapers, and many developments have been made with the development of new materials such as superabsorbent polymers. In parallel, functional attachments such as tapes that can be re-adhesive according to the endless usability of users, lumbar leak prevention devices that prevent excretion from leaking to the waist, and side leak prevention devices that prevent excretion from leaking to the side appeared.

As a technique for preventing the excretion leaking to the side of the various functional attachments described above, in the domestic patent application No. 90-4760 to install a barrier band (Barrior Cuff) to prevent the excretion leaks to the side. However, when a diaper having a coagulation band is installed, another problem occurs that the coagulation band marks or severe contact dermatitis occurs on the baby thigh.

The skin safety problem due to such a coagulation band is a different concept from contact dermatitis, which is different from dermatitis caused by dermatitis caused by skin irritants such as ammonia or dermatitis, which has been mainly studied and studied. The reason for this is usually due to the nonwoven fabric of hydrophobic material of the curable band being manufactured and sold. In the present invention, the material is hydrophobic, which means a material having no absorptive power. While the baby is wearing a disposable diaper, the temperature difference between the inside and outside of the diaper is increased. Therefore, the inside of the diaper becomes high in humidity due to sweat and urine, and the skin is sensitive to irritation. In the case of using a diaper having a stiff band, the skin of the baby, which is sensitive to the stimulus due to moisture, is rubbed with the skin contact surface of the spool band which has no hygroscopicity, thereby causing severe dermal stimulation and causing contact dermatitis.

Therefore, there is an urgent need for the emergence of disposable diapers that are safe from contact dermatitis due to the clot band.

Accordingly, the present inventors have made a thorough study to satisfy the above requirements. The present invention has been found to be able to minimize the occurrence of contact dermatitis by coating on the skin contact surface.

Hereinafter, the present invention will be described in detail.

In the present invention, a disposable diaper having a coagulation band composed of a waterproof wall and a skin tight surface, wherein the waterproof wall is composed of a non-absorbent fabric having no absorptive power, and the skin tight surface is composed of a fabric having an absorbent power of 0.0001 g / cm 2 or more. Alternatively, the present invention provides a disposable diaper having excellent usability such that contact dermatitis does not occur when the disposable diaper is worn by coating.

In the disposable diaper, as shown in FIGS. 1 and 2, the coagulation band is a skin-adhesive surface (2,2 ') which is parallel to the skin of the wall (1,1') which is generally perpendicular to the skin when worn. Consists of. In the present invention, the skin-adhesive surfaces 2, 2 'are made of a highly absorbent fabric or coated. According to the present invention, the surface of the skin-adhesive surface (2,2 ') absorbs moisture contained in the sweat or urine of the skin in close contact therewith, and they also have excellent skin compatibility, so that the friction between the skin and the adhesion surface, namely In addition, physical irritation can be reduced to prevent contact dermatitis.

The superabsorbent fabric should have an absorbency of at least 0.0001 g / cm 2, most preferably cotton, and other blends of synthetic fiber and cotton, such as blending rayon or cotton and polypropylene, or blending cotton and polyethylene. Used.

At this time, when the coagulation band is manufactured using the superabsorbent fabrics of the walls (1,1 ') in addition to the skin-adhesive surfaces (2,2'), the wall (1, 1 ') is transferred to the skin contact surface (2,2'), and when worn, the wet skin contact surface (2,2 ') continuously touches the baby's skin, causing more dermatitis than using hydrophobic fabrics. Let's do it. Therefore, the waterproof walls 1, 1 'use non-absorbent nonwoven fabric as used conventionally.

In addition, in the case of replacing the liquid permeable top sheet 3, which is one of the parts in direct contact with the baby's skin, with a super absorbent fabric, the excrement, which is a function of the liquid permeable top sheet, is quickly transferred to the lower absorber 4, and the body is hydrophobic and moisture. These superabsorbent fabrics have a lot of moisture, which adversely affects skin rashes.

Therefore, it is important to manufacture or coat only the skin contact surfaces 2, 2 'of the coagulation band with cotton.

In the general disposable diaper, the shape of the coagulation band varies as shown in FIGS. 3 (a) to 3 (c). Therefore, in the disposable diaper of the present invention, any one of the various coagulation bands may be selected to provide a close contact with the skin. It is made of superabsorbent fabric or nonwoven fabric and then coated with superabsorbent fabric.

Hereinafter, the present invention will be described in more detail with reference to Examples.

Example 1

A conventional disposable diaper was produced, but the skin-adhesive side of the coagulation band as shown in FIG. 2 was made of a commercially available diaper cloth.

Example 2

A conventional disposable diaper was prepared, but the skin-adhesive surface as shown in FIG. 2 was made of hydrophobic nonwoven fabric and then coated with cotton.

Comparative Example 1

Disposable diapers were produced in a conventional manner without the coagulation band made of cotton or coated.

Comparative Example 2

A conventional disposable diaper was prepared, but the skin contact surface and the wall of the coagulation band as shown in FIG.

Comparative Example 3

A conventional disposable diaper was prepared, but the skin-adhesive side and wall and liquid-permeable topsheet of the coagulation band as shown in FIG. 2 were made of cotton.

The diapers prepared in Examples 1-2 and Comparative Examples 1-3 were used for 100 months 6-12 months old for 3 months, and then determined according to the following criteria, and the contact dermatitis was less than [+]. The incidence of contact dermatitis was determined as considered to occur. The results are shown in Table 1 below.

[Criteria]

[++]: no contact dermatitis

[+]: Contact dermatitis with swelling band marks

[±]: Traces of physical contact

[-]: Reddish red and crushed

TABLE 1

As shown in Table 1, when the skin-adhesive surface of the coagulation band is made of cotton or coated with at least cotton, the incidence of contact dermatitis caused by friction was only 5% and 8%, but the cotton was not used at all. 50% was shown. In addition, when the entire coagulation band was made of cotton, the moisture contained in the absorber after urination was transferred along the wall made of cotton, so that the rate of contact dermatitis was higher than that without using any cotton. More serious results were obtained when the sheets were made of modal cotton fibers. When the results of Table 1 are summarized, it can be seen that the skin has the best skin safety when only the skin-coated surface of the curd band is manufactured with cotton or coated with cotton.

Example 3

A normal disposable diaper was prepared, but the skin-adhesive surface of the coagulation band as shown in FIG. 3 (a) was made of hydrophobic nonwoven fabric and then coated with cotton.

Example 4

A normal disposable diaper was prepared, but the skin-adhesive surface of the coagulation band, as shown in FIG. 3 (b), was made of hydrophobic nonwoven fabric and then coated with cotton.

Example 5

A normal disposable diaper was prepared, but the skin-adhesive surface of the coagulation band as shown in FIG. 3 (c) was made of hydrophobic nonwoven fabric and then coated with cotton.

The diaper prepared in Example 3-5 was used for 100 months 6-12 months of age for three months, and then determined according to the same criteria as in Table 1, and the incidence of contact dermatitis was determined as follows. Shown in

TABLE 2

As shown in Table 2, there is a slight difference depending on the shape of the coagulation band, but in any form of the coagulation band, the skin stability was excellent when the surface was coated with the cotton.

As described above, the disposable diaper having the skin-adherent surface of the coagulation band made or coated with a superabsorbent fabric according to the present invention has a contact dermatitis caused by the coagulation band of the disposable diaper rather than a conventional disposable absorbent product. Has the advantage of being excellent in the prevention effect
