Description

Technical Field [0001] The present invention relates to a functional hygienic band using kaolin,

The present invention relates to a method of manufacturing a functional sanitary napkin using clay (kaolin). More specifically, the present invention relates to a method of manufacturing functional sanitary napkin made of clay (kaolin) And it is possible to prevent and / or inhibit itch, erythema, eczema, menstrual cramps, vaginitis (inflammation) and the like by containing a clay composition having excellent deodorization function.

In general, sanitary napkins are a necessity for women. In the past, they used cotton cloth as a sanitary napkin, but disposable sanitary napkins were introduced in the 1970s. Though disposable sanitary napkins are thinner than cotton sanitary napkins, they are also excellent in absorbency and discomfort for laundry. However, controversy over women 's health has not ceased because they are made from chemical materials rather than cotton.

There is no research showing that sanitary napkins cause certain diseases, but there is a perception among gynecologists and women consumers that the possibility of this is not negligible, as it is a product that directly touches the sensitive body of women.

The quality of a woman's contact with the sanitary napkin is the pathway leading to the uterus, and bacteria can penetrate at any time, so the vaginal interior remains acidic to prevent the invasion of bacteria. In addition, the mucous material in the cervix has inhibited the inflow of bacteria, but during the menstrual period, the acidity of the vagina is lowered and the body immunity is lowered. Therefore, the possibility of infection with the bacteria increases, and the problem is that the sanitary nappe used in this period is made of chemicals . For example, since the disposable sanitary napkin is a stimulant containing a chemical component in order to maintain its function, it is controversial because the itch, rash, eczema, menstrual pain and vaginitis are not related to the sanitary napkin.

The sanitary napkin mainly comprises three parts: a top sheet (cover layer), an absorbent layer, and a waterproof layer. The topsheet is directly touching the skin. Some products use cotton, but most of them are made of chemical materials such as rayon, man-made fibers and polyethylene film. There is a lot of controversy about the detection of formaldehyde in the manufacturing process. Most manufacturers test the formaldehyde and KFDA approval, but they can use it with confidence, but the sanitary napkin itself is a stimulant to the skin and can cause skin diseases. For example, a survey of 716 women in 2000 by the Korean Women's Association found that six out of 10 women experienced skin problems and itching due to use of sanitary napkins.

Some sanitary napkins use bleach to accentuate clean images and are clean, but not good for skin. In other words, most manufacturers are bleaching the top sheet using chlorine, and it is harmful to the human body because dioxin is generated in the process. The bleaching of the topsheet portion using hydrogen peroxide instead of chlorine solves the hazard, but the cost of the bleaching process is ten times higher than that of the conventional one.

Kaolin is kaolin, kaolin, or china clay, and its main component is kaolinite Al ₂ (kaolin). Kaolin refers to earth formed by chemical action of rocks, stones, water or carbonic acid. O ₃ .2SiO ₂ .2H ₂ O, and the halo-site Al ₂ O.SiO ₂ .4H ₂ O. In addition, kaolin is easy to produce in paste state and keeps its undifferentiated state where each particle does not solidify in a solidified state, so that it is easy to drain water and it emits far infrared ray and anion useful for human body, Although usefulness according to each use is known to be unusual, it is used only to manufacture ceramics and the like, and thus it is not utilized fully.

Korean Patent Publication No. 10-0606452 (entitled " Sanitary napkin Containing Oriental Compositions, 2006. 08. 01. Patent Announcement) Korean Patent Laid-Open Publication No. 10-2010-0126987 (title of invention: Hanji sanitary napkin containing herbal medicine, December 03, 2010) Korean Utility Model Publication No. 20-2012-00027217 (Name of Design: sanitary napkin, 2012. 04. 20. Utility Model Release)

The present invention is characterized in that it contains a clay composition having excellent antimicrobial and deodorizing functions, in which a large amount of far-infrared rays and anions are radiated in a part of a topsheet (cover layer) of a sanitary napkin in contact with a human body, And a method of manufacturing a functional sanitary napkin using the clay so as to prevent and / or inhibit the skin, eczema, menstrual pain, inflammation (vaginitis), and the like.

A method for manufacturing a functional sanitary napkin using white clay according to the present invention comprises the steps of: a) preparing a neutral white clay mineral by mixing a white clay powder and water, and b) dissolving the clay powder with an acid to obtain an acid- Preparing a clay soil solution, c) diluting the clay soil solution with clay soil water to prepare an acidic clay soil composition, d) adding the clay composition to the top sheet and drying, and e) To the top of the absorbent layer of the sanitary napkin to complete the sanitary napkin.

The clay stock solution may be around pH 2.5 by purifying the clay powder about 1,000 mesh from which the impurities (or foreign matter) has been removed with acid and purifying it at a temperature of about 80 ° C for about 24 hours.

The clay composition diluted with the clay soil water may have a pH of 4.6 to 6.0.

The white clay stock solution may be in the form of a liquid having a size of 5 to 10 nanometers (nm).

The sanitary napkin of the present invention maintains the normal vaginal acidity (pH 4.5 to 6.5) of the female by maintaining the acidity of pH 4.6 to 6.0 by the clay composition contained in the topsheet, and therefore itching, rash, eczema, Or inflammation and the like are prevented or suppressed.

The present invention relates to a sanitary napkin which absorbs heat waves from the inner surface of a sanitary napkin in contact with a human body through the action of white clay contained in a topsheet, thereby improving local coldness and warming the sanitary napkin, Is effectively deodorized, gives an unpleasant smell, gives a clean feeling, and is also hygienic because it can obtain an antibacterial effect.

The present invention is useful for maintaining cleanliness and promoting health of a woman as the genitalia are kept warm by the action of far infra-red rays having a long depth of penetration, and is also effective for preventing blood circulation and physiological impurity by a large amount of far-infrared radiation.

Since the skin is weakly dried by the acidic (weakly acidic) acid, the problem that the secretion absorbed in the absorbent layer flows out to the topsheet to give a feeling of moistness is solved, the skin feeling is smooth and the antibacterial effect is improved, Inflammation and antiallergic effect can be obtained, so that irritation or irritation of the user's reproductive organs is prevented, and skin moisturizing and soothing effects can be obtained.

The present invention is a very useful invention having an effect such that the quality and reliability of the sanitary napkin is greatly improved due to the above-described effect, and thus it is possible to provide a good image by satisfying various needs of the user.

d) incorporating said clay composition with controlled acidity in a topsheet and drying;

e) attaching the topsheet to the top of the absorbent layer of the sanitary napkin to complete the sanitary napkin; .

20 to 40% by weight of white clay powder (powder) around 1,000 mesh from which impurities (or foreign matters) have been removed and 60 to 80% by weight of water such as ground water and water are mixed and then allowed to stand for 24 hours ), You will get a white clay captain except for the white clay that has settled down.

The clay stock solution was prepared by dissolving clay powder (powder) of about 1,000 mesh from which impurities were removed with an acid such as sulfuric acid or hydrochloric acid, and purifying the clay at a temperature of about 80 ° C for about 24 hours, And the size of the clay that is dissolved by the acid is 5 to 10 nanometers (nm).

The white clay powder emits a very large amount of far infrared rays and anions without being fired at high temperatures, and is excellent in antibacterial and deodorizing properties. The clay powder having a particle size of about 1,000 mesh is well mixed with water and well dissolved in acid.

The diluted clay is mixed with the diluted clay, which is a diluent, at a pH of about 2.5 to obtain a slightly acidic clay composition required for the sanitary napkin.

Table 1 below shows the pH values according to the dilution amount of white clay at room temperature (25.7 ° C to 26.2 ° C). When diluted with 500cc white clay stock solution (around pH 2.5) with 900 cc white clay water, When diluted with 1,400 cc of white clay water, an acidic clay composition having a pH of 5.0 is obtained, and when diluted with a clay of 2,200 cc, an acidic weakly acidic clay composition having a pH of 5.5 is obtained. An acidic clay composition having a pH of 6.0 can be obtained. Therefore, the pH of the clay composition can be optionally controlled according to the degree of dilution of the clay particles.

In the above, the clay composition of pH 4.6 to 6.0 diluted with white clay is in a liquid phase and is within the range of acidic (pH 4.5 to 6.5) required by the human body.

Clay soil solution (around pH 2.5) White clay (pH 7, neutral) The pH of the clay composition 5 cc 900 cc 4.6 5 cc 1,400 cc 5.0 5 cc 2,200cc 5.5 5 cc 3,000 cc 6.0

In the present invention, an acidic topsheet is obtained by spraying, dipping, dipping or coating the topsheet with a controlled acidity of pH in the pH range of 4.6 to 6.0 by dilution, and the acidic topsheet is obtained, and the antibacterial and deodorizing function do.

When a liquid clay composition is contained in the topsheet, it is naturally dried for a predetermined time or heated and dried at a predetermined temperature, so that clay having a size of 5 to 10 nm is ionically or covalently bonded to the surface of the sheet or the non- It does not.

When the topsheet containing the clay composition is adhered to the upper part of the absorbent layer of the sanitary napkin by a method such as joining or sewing, a functional sanitary napkin is completed.

Since the topsheet has an acidic (or slightly acidic) appearance, the skin that is in contact with the skin is weakly dried, so that the wet condition is alleviated during use, the secretion absorbed in the absorbent layer of the sanitary napkin flows out to the topsheet, It is not only comfortable to wear but also has antimicrobial effect, anti-inflammation and anti-allergic effect can be obtained, and it is possible to prevent irritation or itching in the local area of the user and to obtain skin moisturizing and soothing effect .

The three topsets treated with the clay composition of the present invention were submitted to the Korean scientific research institute and diluted with an appropriate concentration by serial dilution method. After culturing at 37 DEG C for 5 days, the viable counts of Candida albicans Candida albicans has not been detected, so it can be deduced that it does not cause any itching in the human body.

On the other hand, most of minerals, copper and plants are polar, but since the clay or clay composition of the present invention is non-polar having no polarity, it can be applied to most minerals, copper and plants, It is a multifunctional mineral that emits powerful quantum energy at low temperatures, far-infrared rays, and natural anions to enhance immunity and bio-immune ability in copper and plant organisms.

The white clay of the present invention is composed of minerals such as silica (SiO2), alumina, iron, calcium, magnesium, calcium, sodium and titanium and various enzymes to radically emit far infrared rays and anions necessary for growth and growth of plants and plants. Therefore, 'Ki is the living earth of life'. In addition, clay has a large honeycomb structure with a large surface area, and has many spatial structures, and stores a large amount of far infrared rays and anions. When heat is received, these far infrared rays and anions emit so as to stimulate molecular activities of other objects to purify the natural environment. It is an important resource to promote health. The effects on the human body include immunity and self-healing ability, improvement of blood flow, and increase of alpha-waves. Examples of the effects include maintenance of health, prevention of sickness, recovery, comfort and concentration .

In the present invention, the far infrared ray emissivity (5 to 20 μm) of the top sheet treated with the clay composition was measured to be 0.902, and the far infrared ray radiation energy (W / m ² μm, 37 ° C.) was measured to be 3.48 × 10 ² .

On the other hand, the normal vaginal acidity of women maintains a neutral pH of 6-8 similar to skin before puberty, and when sexual hormone is released into puberty, the pH of the vagina with the change of body becomes acidic 4.5 ~ 6.5 .

In addition, there are five or six bacteria in the vagina of women, but most of them are Lactobacillus, and Lactobacillus is decomposed into lactic acid by lactic acid and becomes a nutrient. Lactic acid, a metabolite, plays a role in maintaining vaginal acidity. When lactobacillus is decreased, it causes overgrowth of anaerobic bacteria and causes vaginitis. During the menstrual period, the acidity of the vagina decreases and the body's immune system decreases.

However, the functional sanitary napkin of the present invention maintains the normal in vivo acidity (pH 4.5 to 6.5) of the woman while having the acidity of pH 4.6 to 6.0 by the clay composition contained in the topsheet. Therefore, Eczema, menstrual cramps, vaginitis, inflammation and the like are prevented or suppressed.

The sanitary napkin of the present invention not only helps women's vaginal health since a large amount of far-infrared rays and anions are emitted from the clay composition treated in the topsheet, but also has a deodorizing function so that the odor of the secretion is effectively deodorized, It is also hygienic because it has antimicrobial action, it promotes metabolism and helps to balance with body rhythm.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It is self-evident to those of ordinary skill.
