The present invention relates to a disposable absorbent product, and more particularly, a disposable disposable product having a double coagulation band attached to a disposable absorbent product composed of a liquid permeable sheet, an absorbent body, a liquid impermeable back sheet, and the like, to prevent leakage to the thigh area when worn. It relates to an absorbent product.

In the present invention, the disposable absorbent product is a disposable diaper, which means a baby diaper absorbing urine and feces of babies and an adult diaper used by incontinents mainly composed of elderly people.

Such disposable diapers should have excellent absorption characteristics such as absorption rate and absorption amount as basic functions, have no skin side effects when worn, and can prevent the aggregation of absorbents when worn. Are being developed.

For example, Korean Patent Publication No. 84-6751 discloses a phenomenon in which excretion leaks to the thigh area by installing one coagulation band on the thigh area of the disposable diaper to prevent the leakage of the excrement to the thigh area when there is a large amount of excretion of the wearer. However, as a solid layer of non-woven fabric, it was able to completely prevent leakage of the thigh. In addition, there is a product installed in Unicharm as a disposable absorbent product that is sold in Japan, but it has a double coagulation band, but this product is designed to make the outer coagulation band shorter than the inner coagulation band when designing the coagulation band. Leakage could not be properly prevented when worn as a main function, and the elastic body of the outer solidification band was used as a polyurethane foam band to compensate for this problem. Since the foam band lacks elasticity, the foam band has a disadvantage of causing physical side effects on the skin of the wearer.

The present invention provides a disposable diaper composed of a liquid permeable top sheet, a liquid impermeable back sheet, an absorber, and the like, wherein a double solidification band having the same height is provided, and an elastic chamber of 500 to 840 deniers as an elastic body of the solidification band. It is an object of the present invention to provide a disposable diaper that solves the above problems.

Hereinafter, the present invention will be described in detail.

Disposable diaper basic components of the present invention is composed of a liquid permeable top sheet 1, an absorbent body (3), a liquid impermeable back sheet (4), etc., the basic component is a liquid permeable top sheet (1) and both sides ( 2), between the external solidification bands 6 and 6 ', which are connected to the 2' and 2 ', and the two sides 2 and 2' of the liquid-permeable top sheet 1, and are bonded by hot melt. The formed inner coagulation bands 5, 5 'are formed, and the thigh area when worn by applying elastic yarns 7, 7', 8, and 8 'to the ends of the inner and outer coagulation bands. It was prepared to be in close contact with. At this time, since the absorbent body (3) in the center of the liquid permeable top sheet (1), a hydrophilic nonwoven fabric was used to absorb the body fluid well, the hydrophobic nonwoven fabric treated to prevent the leakage of secretion on both sides (2).

In the present invention, the inner pore bands 5, 5 'and the outer pore bands 6, 6' have the same height, and when either one of the inner and outer pore bands is long or short, the double pore band is worn. The feces could not properly prevent leaking into the thigh area, which is a basic function.

In addition, the height of the double curd band is 20 to 30mm is appropriate, and if the height of the curd band is less than 20mm, the leakage preventing function is lost. If the curd band is more than 30mm, the elasticity of the wearer's skin is excessively applied, causing skin redness The height of the double solidification band is preferably 20 to 30mm. Lycra (Lycra: manufactured by DuPont) was used for the elastic yarn included in the double solidification band, and the thickness of the elastic yarn was a round or oval between 560 and 840 deniers. In addition, a natural rubber may be used instead of the ligka as the elastic yarn, and the thickness of the natural high material may use 025 × 0.51 to 0.43 × 0.51mm.

In the case of ultra pattern manufactured and sold by Unicharm, Japan, the inner curd band uses denier-like ricra, but the outer curd band uses polyurethane rom band, and the outer curd band has a small elasticity and strong elasticity. Many skin sores occur.

Hereinafter, the present invention will be described in detail by way of Examples and Comparative Examples.

Example 1 and Comparative Examples 1 and 2

Example 1 and Comparative Examples 1 and 2 show the degree of leaking into the thigh area and the inner coagulation band, even if the diaper having two coagulation bands is worn when the disposable diaper having one coagulation band and two coagulation bands are worn. Table 1 shows the degree of occurrence of leakage phenomenon in the case of the same height difference between the and the external coagulation bands.

Example 1

The liquid-permeable topsheet 1, the absorbent body 3, and the liquid-impermeable backsheet 4 as the basic components, both sides 2, 2 '(hydrophobic nonwoven fabric) of the liquid-permeable topsheet 1 and Connected between the outer solidifying bands 6, 6 'upright containing 860 denier elastic yarns and between the liquid permeable top sheet 1 (hydrophilic nonwoven fabric) and both sides 2, 2'. The inner melt bands 5 and 5 'containing 860 denier elastic yarns were bonded by hot melt to form the same, and the heights of the inner melt bands and the outer melt bands were equal to 25 mm. It was prepared according to the preparation method.

Comparative Example 1

The liquid permeable topsheet, the liquid impermeable backsheet, the absorber, and one solidification band (height 25 mm) were prepared according to the conventional method for preparing a disposable absorbent article.

Comparative Example 2

It consists of a liquid permeable top sheet, a liquid impermeable backsheet, an absorber and two solidification bands, but the outer solidification band (10mm) is designed to be shorter than the inner solidification band (25mm), so it is 840 denier Except for using the elastic yarn of was prepared according to the usual manufacturing method of the absorbent product.

** Experimental Method **

There is no evaluation method that can be evaluated mechanically to the extent that the thigh leaks or the physical irritation of the skin, so the user was directly worn and evaluated, the test method and symptom criteria are as follows.
