The present invention is a cotton material applied to the waterproof film, and more specifically, the disposable film is applied to the waterproof film (backsheet) of the components of the disposable absorbent product to the natural gauze material, and only the absorbent portion requiring waterproofing is applied by applying the waterproof film (Lamination). The present invention relates to a disposable absorbent product which prevents skin sores caused by impermeability to air when worn.

Generally, disposable absorbent products are products that simply absorb and remove body fluids secreted and excreted by physiological action. Disposable diapers used to remove urine and feces in infants, menstrual secretions and vaginal secretions used by women. It refers to sanitary napkins and panty liners, etc. and has a comprehensive meaning.

Disposable absorbent product in the present invention refers to disposable diapers for infants and incontinence. Disposable diapers are evaluated for their quality according to the rate of absorption, absorption and skin stability. That is, they should be absorbed as soon as they are secreted. The higher the amount of secretion absorbed, the better the product is. Usability should be excellent and the product should have excellent skin stability without diaper rash such as red spots and skin swelling on the skin for long time wearing.

On the other hand, conventional disposable absorbent products have excellent absorption rate, absorption amount, etc., but too many sides of the skin are covered with a waterproof film, and thus there is a disadvantage in that diaper rashes such as skin rashes and red spots are generated due to poor ventilation. The root cause of diaper rash can be attributed to the structure that is caused by too much area of skin wrapped in waterproof film, that is, diaper breathability.

In order to solve such a conventional problem, Korean Patent Publication No. 90-5652 has tried to remove diaper rash such as skin rash and red spots by adding baby powder among the components of disposable absorbent products, but baby powder is fundamental to solve such problems. Could not be removed. In addition, when manufacturing disposable absorbent products using a breathable film, it is superior in breathability than a non-breathable film product, but it does not reduce skin rash prevention technology because it does not reduce the area surrounding the skin. To this end, it is desirable to reduce the skin area of the waterproof film as a fundamental problem, and it has been expected that disposable absorbent products that can achieve the purpose of excellent skin safety and more hygienic products.

Therefore, the present invention partially adheres the waterproof film to the gauze of the liquid impermeable back sheet in the disposable absorbent product composition consisting of a liquid permeable top sheet, a downy pulp, a super absorbent resin, and a liquid impermeable back sheet. By applying it as a back sheet, the absorbent part has the same effect as the breathability of the existing product, and the edge part without the absorber has the purpose to provide skin safety that is completely ventilated with the outside air.

Hereinafter, the present invention will be described in detail.

According to the present invention, the liquid impervious back sheet 101 is formed by adhering the waterproof film 104 only to the natural gauze of cotton material and the center portion (absorbent position) of the gauze and using it as a waterproof film for disposable diapers. The present invention was developed by inventing a breakthrough product that completely solves the disadvantages of skin red spots and skin rashes caused by failing to discharge the sweat and moisture generated from the side edges of the baby's hips by applying the part as a waterproof film. It was completed.

Hereinafter, the present invention will be described in more detail based on examples.

[Examples 1 and 2 and Comparative Examples 1 and 2]

A conventional disposable absorbent article composed of a liquid permeable top sheet 105, an absorbent 103 made of downy pulp, a super absorbent polymer, a tissue 106, an elastic body, and a liquid impermeable breathable back sheet was compared. A conventional disposable absorbent product having the same constitution as and consisting of a liquid impermeable non-breathable backsheet was referred to as Comparative Example 2, and Example 1 gauzes a liquid impermeable backsheet to prepare a product in the same configuration as Comparative Example 1. ) And a breathable film was applied by applying a back sheet partially bonded, and Example 2 manufactured the product in the same configuration as Comparative Example 1 in which the liquid impermeable back sheet was partially bonded to the gauze 101 and the non-breathable film. It was prepared by applying the sheet.

Examples 1 to 2 and Comparative Examples 1 to 2, four types of products prepared as described above were worn by 100 babies using disposable diapers 3 to 12 months, and the parents were surveyed. The results are summarized in Table 1.

The use of the four types of diapers was worn every other week, for a total of eight weeks of consumer survey periods.

[Judgment of symptoms]

[++]: no diaper rash

[+]: Red spots

[±]: red spots are strong and there is a rash

[-]: Red spots are strong and sores are widespread

As can be seen in Examples 1 and 2 and Comparative Examples 1 and 2, it was found that the baby's diaper rash occurrence rate (%) was significantly different according to the type of liquid impermeable back sheet.

Specifically, the results of the analysis of Comparative Example 1 manufactured with the conventional breathable waterproof film showed a diaper rash rate of 30%, and the Comparative Example 2 manufactured with the same manufacturing method and made of the waterproof backsheet with the breathable waterproof film 35 The diaper rash rate of% was generated, but in the case of Example 1, the skin rash incidence rate was 0%, and in Example 2, the skin rash incidence rate was 1%, and the skin rash incidence rate of the present invention was significantly higher than that of the conventional products. The decrease is considered to be a result of applying the back sheet to which the waterproof film is partially bonded to the gauze.

[Examples 3 to 4 and Comparative Example 3]

Partial waterproof film of the disposable absorbent product component consisting of a gauze back sheet to which a liquid permeable top sheet 105, a pulp pulp, an absorbent 103 made of a superabsorbent resin, a tissue, an elastic body and a partially waterproof film 104 are bonded. Example 3, 1/4 of the product made of the ratio (W / W) of the diaper full width (W) and the waterproof film width (W) of the components of the gauze back sheet It was referred to as 4, the product produced in 1/6 was referred to as Comparative Example 3. The consumer survey was conducted by the same method as carried out in Examples 1 and 2 and Comparative Examples 1 and 2, and the results are summarized in Table 2.

[Judgment of symptoms]

[+]: Droppings don't leak

[±]: feces seep out

[-]: Feces gland

As can be seen from Table 2, in the case of Examples 3 to 4, the leakage prevention rate is very excellent, that is, if the ratio of the waterproof film width to the full width of the product is 1/5 or more, the generation rate of the product is extremely low, and thus the excellent product usability is maintained. As can be seen from the 1/6 or less in the case of the waterproof film does not perform the function and the high leakage rate is a disadvantage that can not fulfill the function as a disposable absorbent product, so in the present invention the product width (gauze width: W) and waterproof film width (W ) Ratio (W / W) is 1/5 or more to reach the appropriate quality level required by the present invention.
