Disposable absorbent products

The present invention relates to a disposable absorbent product having excellent skin rash prevention effect, and more particularly, to a liquid permeable upper sheet, a liquid impermeable back sheet forming an outer surface when worn, and an absorbent body positioned between the top sheet and the back sheet. The present invention relates to a disposable absorbent article excellent in preventing skin rashes by adding bamboo salt to some of the absorbent components of the conventional disposable absorbent article.

A general disposable absorbent product is a product that absorbs body fluids excreted by various physiological actions, that is, a product that absorbs urine and feces secretions, menstrual secretions and vaginal secretions, and more specifically, disposable diapers used by infants or incontinence. (Diaper), women's sanitary napkins and panty liners.

Disposable absorbent products consist of a liquid-permeable top sheet that is in direct contact with the wearer's skin when the disposable absorbent product is worn, a liquid-impermeable back sheet that forms an outer surface when worn, and a liquid-permeable top It consists of an absorbent core positioned between the sheet and the liquid impermeable backsheet.

Among these disposable absorbent article components, the liquid permeable upper sheet is composed of a synthetic nonwoven fabric which allows body fluids to quickly pass through the absorbent body, which is typically used to prevent body fluids absorbed in the absorbent from contacting the wearer's skin again. Hydrophobic treatment is used. In addition, the absorber is generally composed of fluff pulp, super absorbent polymer, tissue, etc., and absorbs the body fluid passing through the liquid permeable top sheet at a high speed. It functions to receive and store body fluids to prevent them from contacting the skin again. The technology of absorbers has led to the development of super absorbent polymers, and the development of more absorbent materials will solve the problem of minimizing the volume reduction and environmental impact of disposable absorbent products. The liquid impermeable backsheet performs the function of preventing the wearer's clothing from being contaminated by body fluids absorbed in the disposable absorbent article and mainly uses polyethylene film.

The current state of the art in disposable absorbent products, including disposable baby diapers, incontinent diapers, and women's sanitary napkins, is in terms of the rate and amount of absorption of fluids secreted by physiological action. Since the primary performance of this absorbent product has reached a considerable technical level, there is no inconvenience for the user.

However, the problem of disposable diapers should not have side effects on the skin of the wearer when using the product, and especially when wearing disposable diapers and sanitary napkins, there should be no pruritus (skin itching), red spots on the skin (erythema) and skin sores. When the disposable absorbent products are worn, the skin application area is severely itchy and red, and in severe cases, the skin is bitter and the user has a disadvantage of severe discomfort. There are various theories that the cause of such skin side effects are due to ammonia, superficial bacteria, physical absorption caused by friction of the disposable absorbent product and the skin, and excessive moisture, but this is only an estimation and no clear mechanism has yet been revealed. It is clear that skin itch, pruritus, is an early symptom of skin rash and sores. Although this pruritus presents many side effects to the wearer when the disposable absorbent product is worn, there have not been specific proposals to solve the disadvantage.

The present invention has been devised in accordance with the present invention, an object of the present invention is to prevent the itching of the skin by adding the bamboo salt which has been transmitted by the Korean folk non-discharge to some of the components of the usual disposable absorbent products to solve the above problems disposable disposable products To provide.

Disposable absorbent articles according to the present invention consist of a liquid permeable top sheet, a liquid impermeable back sheet, and an absorbent consisting of tissue, fluff palp and super absorbent polymer, all or all of these absorbents. Adding bamboo salt to some prevents itching when wearing disposable absorbent products.

In addition, in the present invention, bamboo salt may be added to tissues, fluffy pulp, and superabsorbent resins, or may be added alone.

Moreover, the addition amount of bamboo salt according to the present invention is preferably 0.1 to 30% by weight of the absorbent weight, which is less than 0.1% by weight of the total weight of the absorbent consisting of tissues, fluffy pulp and superabsorbent resin does not adequately prevent skin itching, If the absorbent weight exceeds 30% by weight, the salt component in bamboo salt causes another skin side effect.

Bamboo salt used in the present invention is synthesized by the fire method (火 法) using bamboo and salt, which is a bamboo to create a new cell cells (生 新 作用) and salt to prevent sterilization and decay By repeating the treatment at high temperatures several times in the tank, they remove the toxins they carry and maximize their efficacy. Salt used in the production of bamboo salt is usually used as a sun salt, and in addition to edible salt, reagent grade sodium chloride and potassium chloride, bamboo is usually bamboo or cotton bamboo, but there is no need to limit the type of bamboo.

Bamboo salt used in the present invention is a commercially available bamboo and ocher, which acts as a new life, and the bactericidal and anti-corrosive salt are repeatedly treated in a furnace at a high temperature of 1000 ° C. or higher to remove toxins, preventing skin itching and cell growth. The effect of sterilization, such as to maximize the effect.

The production method of bamboo salt used in the present invention is as follows. Grown under the sea breeze, preferably cut for 3 years in order to pierce one side and block one side, and then squeeze the sun-salt into the barrel and squeeze the unresolved yellow soil in the mountain nine times and dry it in the shade. After kneading, put red larch, reinforcement mugwort, and leaves about 1cm, and seal the end 2cm with kneaded ocher soil. The bamboos made in this way are placed in a porcelain agate made of ocher, pines are lined up, and the pine trees are sown. After about 24 hours, crush the remaining salt mass while absorbing bamboo, red larch, wormwood and ocher gin finely, and put it in a new bamboo barrel in the same way as the first time. Repeat the ninth, and use only special stainless steels built underground to produce high heat of 1500 ℃ or higher. Then, it flows down like the molten metal of the furnace, and when the fire is turned off, the liquid solidifies and the changed mass is bamboo salt, which is finely ground and used in the present invention.

The method of adding bamboo salt in the present invention is a method of injecting bamboo salt powder in the production of disposable absorbent products, a method of dissolving bamboo salt powder in a solution and spraying the solution, or when preparing an absorbent such as tissue, downy pulp and super absorbent resin. It can be applied in a variety of ways, such as.

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

<Example 1>

Disposable diapers prepared by adding 0.1% by weight of bamboo salt of the total weight of the absorber to the fluffy pulp of a conventional disposable diaper composed of a liquid permeable top sheet, a liquid impermeable back sheet and an absorbent of tissues, downy pulp, and superabsorbent polymer by the above-described manufacturing method. Was prepared.

<Example 2>

A disposable diaper was manufactured in the same manner as in Example 1, except that 1% by weight of the total weight of the absorbent was added to the bamboo salt.

<Example 3>

A disposable diaper was manufactured in the same manner as in Example 1, except that the addition amount of bamboo salt was added by 10% by weight of the total weight of the absorbent body.

<Example 4>

(How to evaluate itching when wearing)

Evaluation of the itch at the time of wearing disposable diapers prepared by Examples 1 to 4 and Comparative Examples 1 to 3 was performed according to the following test method and evaluated according to the following symptoms and judgment.

Clinical trials were performed on 100 incontinent persons in their 50s and 60s for the disposable diapers manufactured by Examples 1 to 4 and Comparative Examples 1 to 3 to determine the degree of itching directly to the wearer. Table 1 shows. In addition, the evaluation of the stinging, which is expected to be an excessive addition of bamboo salt, was directly judged by the wearer, and the results are shown in Table 2.

TABLE 1

Note 1) [++]: Itching at all is not felt.

[+]: Sometimes wear itching symptoms when worn

[±]: always feel mild itching symptoms when worn

[-]: Itching is very strong discomfort when worn

Note 2) Very good: 100% or more of [+]

Excellent: more than 80% and less than 100%

Normal: When more than 70% and less than 80%

Poor: If more than [+] is less than 70%

TABLE 2

Note 1) [++]: You do not feel any hot symptoms when you wear it.

[+]: Sometimes wear and feel symptoms

[±]: always feel mild warm symptoms when worn

[-]: Always feel severe hot symptoms when worn

Note 2) Excellent: When [++] is 100%

Excellent: When [+] is 10% or less

Normal: When [+] is 10 to 20%

Poor: If less than [+] exceeds 20%

In summary, Table 1 and Table 2, the more the content of bamboo salt compared to the absorbent weight of the disposable diaper, the better the symptoms of itching, and the smaller the content of bamboo salt, the better the symptoms of stinging of the skin. Thus, as can be seen in Examples 1 to 4, when it is added 0.1 to 30% by weight of bamboo salt of the total weight of the absorbent body of the disposable diaper, itching and stinging symptoms can provide a superior disposable diaper than Comparative Examples 1 to 3 Could.
