Description

FIELD OF THE INVENTION [0001] The present invention relates to an active mineral-containing sheet for sanitary articles,

The present invention relates to an active mineral-containing sheet for sanitary articles and a method for producing the same.

In general, sanitary articles such as sanitary napkins, diapers, etc. are disposable consumables which are worn outside the body and absorb and discharge human excretions such as menstrual blood, feces, or urine which are discharged during a menstrual period or at a normal time. For example, sanitary napkins are being researched with the emphasis on absorbency of body fluids, prevention of contamination of clothes, or wearing comfort, as the user must maintain frequent cleansing even when the amount of physiology is excessive or small. Have been proposed for the purpose of keeping the wearer's area always clean and hygienic.

In recent years, ceramics that emit far-infrared rays beneficial to the human body have been researched and developed and used in various daily necessities. For example, various food containers, clothes, bedding, and the like. Particularly, in clothes, a product in which ceramic is applied to an undergarment that directly contacts the skin of the body is being released.

Major items required for existing sanitary products are summarized as follows.

The first is about how dry the skin can be maintained by wearing hygiene products with dry feeling.

The second relates to the ease of fastening means for attaching clothing and sanitary articles with adhesiveness.

Third, it concerns leakage and clothing pollution.

Leaks are the most basic and important issues in disposable absorbent products. For example, in the case of sanitary napkins, liquid impermeable back sheets and leakage prevention wires are used to enhance leakage prevention.

Fourth, it relates to the removal of the odor generated when the excrement is discharged.

The cause of the menses is the combination of various protein decay, ammonia, trimethylamine, hydrogen sulfide and mercaptan contained in human excreta such as menses, feces, urine, etc., and it can be a source of skin irritation, Or it can cause a variety of bacterial infections that cause colds, fever, or itching that are transmitted through the anus. It can also be a problem, especially in the case of a woman, in the summer or on a high secretion day.

Today, as a method of removing the odor of general sanitary articles, a method of applying a superabsorbent resin so as to absorb human excreta to confine the odor circle or to add a herb or other herb to the hygiene article absorbent layer is applied to the core laid layer Inhibiting the generation of bacteria by inserting them, and in the case of women, methods for obtaining effects such as easing of menstrual pain are widely used. However, some of these products seem to have a deodorizing and pharmacological effect, but the effect thereof is insignificant, and in order to maximize the pharmacological effect, it is necessary to install near the uppermost part of the sanitary article, May be exposed and cause visual discomfort.

On the other hand, Patent Document 1 discloses a method of extracting minerals from strong acid substances such as sulfuric acid, hydrochloric acid and nitric acid, extracting minerals from strong base materials such as sodium hypochlorite, mixing the two extracts and neutralizing them, . However, there has been a limitation in utilizing the liquid mineral extracted through the mixing reaction of strong acid and strong base materials harmful to the human body to use it in the sanitary napkin product directly contacting the human body.

Method for manufacturing activated mineral-containing sheet for sanitary articles

Ceramics is a high-efficiency ceramics material with high far-infrared emissivity in the wavelength range absorbed and radiated by the human body. In order to maximize the far-infrared radiation effect, ceramics materials with high efficiency are selected and their radiant energy is analyzed. This is important.

If the wavelength is shorter than that of visible light, which means light that can see the object, ultraviolet rays, conversely, it is infrared rays when the wavelength is longer than that of visible rays, and far infrared rays are called longer ones. Such far-infrared rays penetrate deeply into the skin in the wavelength range of 4 to 1000 탆 and are converted into heat, and the absorption action is concentrated in the wavelength range of 5 to 30 탆. Far infrared rays with a wavelength range that can be easily absorbed by the skin of the human body, when absorbed by the human body, resonate and absorb the molecules in the body and cause resonance motion. The far infrared ray skin absorption can reach 4 ~ 5cm of the skin by the depth calendar of the far-infrared rays, penetrates blood and moisture, and activates the metabolism. Influence of far-infrared rays on the living body is due to microvessel expansion, blood circulation promotion, tissue activation, etc. These effects function to improve the health of the body. Basically, far infrared rays are emitted from germanium, silicon oxide, It is known to be released.

1, a conventional pad type sanitary napkin 100 includes an inner sheet 3 as a liquid-permeable cover made of a nonwoven fabric or the like, an absorbent sheet 2 containing a polymeric absorbent material And a cover 1 which is a liquid-impermeable cover that covers one side of the absorbent sheet 2 and prevents leakage of the secretion to the outside, thereby absorbing secretions and preventing them from leaking or flowing.

2, the pad type sanitary napkin including the active mineral-containing sheet according to an embodiment of the present invention includes a liquid permeable sheet 30, an absorbent pad 20, a liquid impervious sheet 10, Permeable sheet 30, and an active mineral-containing sheet 40 impregnated with a liquid active mineral, for example, a sheet such as a nonwoven fabric, and dried, is disposed between the liquid pervious sheet 30 and the absorbent pad 20 .

The pad-type sanitary napkin 200 including the active mineral-containing sheet can maximize the deodorizing effect because the active mineral-containing sheet 40 is located in the menstrual blood absorption path, and when the sanitary napkin is exchanged, The deodorizing effect can be maintained because the active mineral-containing sheet 40 is present in the passage region of the odor volatilizing from the active mineral sheet 20.

3, the tampon including the active mineral-containing sheet according to one embodiment of the present invention includes an active mineral-containing sheet 50 and an absorber 51 surrounding the outside of the sheet 50, (52) connected to the main body (51).

The activated mineral-containing sheet for sanitary goods, which is a feature of the present invention, comprises a step of obtaining a natural mineral powder by pulverizing a mineral including diatomaceous earth, clay and germanium ore, electrolyzing the water in an electrolytic apparatus equipped with a selective ion membrane, To 4.0 of electrolytic water; reacting the powder and the electrolytic water in a reactor at a temperature of 30 to 45 ° C under a condition where sunlight and air are blocked; extracting the active mineral from the liquid phase; And then drying it.

Diatomaceous earth is mainly composed of silicon dioxide (SiO ₂ ), white or grayish white. It is light and soft enough to touch the powder with the finger. Because of its fine porosity, it is highly absorbent and is a poor conductor of heat. The silicon dioxide is an oxide of silicon and is also referred to as silica and is used as a major component of mulite, cordierite and loess, well known for emitting far-infrared rays. It has the effect of releasing a large amount of far infrared ray in a small amount and has a low cost and is widely used in far-infrared ray radiation research.

Clay is fine soil particles having a diameter of about 0.002 mm or less. When weathered and decomposed, mainly silicon, aluminum and water are combined to form a clay mineral. The montmorillonite is a silicic mineral produced by the volcanic activity of the Cretaceous period about 12 million years ago, and is useful for the human body such as chlorite, amphibole, titanium oxide, potassium and sodium. Aerobic microorganisms (live cells) and titanium oxide that are beneficial to the human body, which are not found in minerals, amino acids and general minerals, promote capillary vasodilation and blood circulation, helping cells to activate and helping their immune system.

Unlike yellow loess which is emitted only at high temperature, far infrared rays emitted from montmorillonite are characterized by radiating at a human body temperature of 37 to 37.5 ° C. In addition to excellent deodorizing action and anion that activates cells, absorption of human body, promotion of metabolism and blood circulation It is effective to prevent the aging of the human body and adsorb waste and harmful substances accumulated in the human body.

Montmorillonite promotes capillary dilation and blood circulation by anion to help cell activation, and to help nerve stabilization and immunity enhancement. The far-infrared radiation of montmorillonite promotes blood circulation by the emission of far-infrared rays having a wavelength of 5 to 20 μm, has excellent deodorizing power and absorption power, and distributes the far-infrared radiation distribution uniformly without tilting to one side and has a high thermal conductivity. Thus, as time passes, the moisture can be further maximized by evaporating urine, sweat and / or blood into water vapor.

Germanium has excellent heat resistance and low thermal expansion properties, and is known to emit far infrared rays higher than other oxides. Therefore, germanium has been widely used as far-infrared radiation material. When germanium comes into contact with the skin, germanium ions enter the body, resonance and resonance movements, and are discharged out of the body within 20 to 30 hours with various harmful substances, so there is little poisoning or side effects. In addition, germanium is a building material and has functions such as deodorization, mold, dehumidification, air purification, and heat.

Ceramic for emitting far infrared rays is high in general, far-infrared emissivity at room temperature, are known to be long withstand the high temperature, a raw material of ceramics such as Al ₂ O _3, MgO, SiO _2, TiO ₂ is used, alone or in combination.

Natural non-metallic minerals are rarely used directly as raw materials, but they are purified by physical and chemical methods to make pure non-metallic inorganic materials. The far-infrared ray emission materials are representative materials of elvan and germanium, and the major minerals generally used are shown in Table 1 below.

Therefore, in the method of producing an active mineral-containing sheet for sanitary ware according to an embodiment of the present invention, diatomaceous earth, clay, and germanium ore, which are optimal for far-infrared radiation, are applied as raw materials and pulverized to obtain natural mineral powder.

The natural mineral powder obtained by decomposing diatomaceous earth, clay and germanium ore may have an average particle size of about 300 to 350 mesh in view of workability and efficiency of extracting active minerals, but is not limited thereto.

The diatomite, clay and germanium ore may have a mixing ratio in the range of 2.5 to 4.5: 2: 3.5 to 5.5 by weight, more specifically, when the mixing ratio of about 4: 2: 4 is satisfied, the maximum value of the far- What has been confirmed through experiments.

However, the mixing ratio can be varied through various experiments, and is the experimental value obtained by the present inventors up to now, but it is not necessarily limited to the mixing ratio.

Actually, when the above components were mixed at a ratio of about 4: 2: 4, the far infrared ray emissivity was the best at 0.893, and their chemical composition contents are as shown in Table 2 below.

Silicon dioxide (SiO ₂₎ 67.2 wt% Aluminum oxide (Al ₂ O ₃₎ 16.2 wt% Titanium oxide (TiO ₂ ) 0.42 wt% Magnesium oxide (MgO) 7.92 wt% Calcium oxide (CaO) 1.57 wt% Sodium oxide (Na ₂ O) 1.03 wt% Potassium oxide (K ₂ O) 0.77 wt% Germanium (Ge) 4.89 wt% Dry content (Lg-Loss) 12.4 wt% Cation Exchange Capacity (CEC) 90 to 120 (meq / 100 g)

According to the present invention, electrolytic water having a pH of 2.0 to 4.0 is obtained by electrolyzing water in an electrolytic apparatus equipped with a selective ionic membrane. The water used for the electrolysis can be easily obtained tap water or ground water, and is not particularly limited to these two. The selective ionic film is a very thin film and selectively passes only ions without passing water. Therefore, electrolytic water is generated when water is electrolyzed by applying a selective ionic membrane in the electrolytic apparatus. Acidic water is generated at the anode of the apparatus, and alkaline water is generated at the cathode.

The electrolytic water according to an embodiment of the present invention applies electrolytic water having a pH of 2.0 to 4.0 generated at the anode of the electrolytic apparatus, which is effective in suppressing the growth of bacteria and removing odors.

The selective ionic membrane is mainly formed of a material such as polypropylene (PP), polyethylene (PE), polyamide (PA), cellulose acetate (CA) and the like. The membrane is a heterogeneous membrane having a thickness of 400 to 450 μm And temperature stability.

The natural mineral powder and the electrolytic water having a pH of 2.0 to 4.0 are then mixed in a reactor and heated at a temperature of, for example, 30 to 45 ° C, for example, for about 6 to 10 days, preferably for 7 days The active minerals in the liquid phase are extracted by reacting for 8 days in an environment where sunlight and air are blocked.

The electrolytic water having a pH of 2.0 to 4.0 is harmless to the human body and is non-toxic. For example, when the pH is about 2.7 and the oxidation-reduction potential (ORP) is about 1100 mV or more and exposed to air and sunlight in the atmosphere, it has a property of returning to a state similar to pH. Accordingly, the electrolytic water according to an embodiment of the present invention reacts in a so-called darkroom atmosphere in which sunlight and air are blocked.

Further, the reaction temperature goes to a temperature of about 30 to 45 DEG C, that is, to a temperature somewhat higher than room temperature. Specifically, the reaction temperature is preferably from 35 to 45 캜, more preferably from 40 to 45 캜, and an optimum state can be realized at about 40 캜. The reason for setting the reaction temperature higher than room temperature, more specifically, about 40 캜, is to keep the pH of the active minerals to be formed through the reaction within the range of from 3.0 to 5.0, which is a weak acidity.

The ionization constant (Kd / 10 ^-14 ) of water according to temperature is proportional to, for example, 1.2 at 30 ° C, 8.0 at 50 ° C, and increases with increasing temperature. Therefore, in order to prevent the electrolytic water from returning to the state before the electrolysis, for example, during the reaction for 6 to 10 days for sufficient elution of the active minerals, Lt; 0 > C.

When mixing the natural mineral powder and the electrolytic water, the mixing ratio has a weight ratio of about 0.2 to 0.7: 1, preferably about 0.5: 1. If the ratio of the mineral powder is less than 0.2, economical efficiency is deteriorated. If it is more than 0.7, the proportion of the particles in the mixture becomes high, and the extraction efficiency may be lowered.

When the pH of the liquid active mineral is 3.0 to 5.0, it is excellent in sterilizing power and antibacterial power and can have a non-irritating effect on the skin. When the pH of the active minerals is less than 3.0, the acidity becomes stronger to stimulate the skin of the human body. If the pH is more than 5.0, the effect of bacterial growth or antibacterial action may be reduced.

Alternatively, the method according to an embodiment of the present invention may further include, after the step of extracting the active minerals in the liquid phase, filtering the active mineral in the liquid phase with a microfilter.

Representative components of active minerals obtained according to one embodiment of the present invention are shown in Table 3 below.

Item unit content Sample method Ge Mg / L 2.4 ICP Si Mg / L 24.2 ICP Mg Mg / L 542.5 ICP Al Mg / L 314.2 ICP Ti Mg / L 49.2 ICP Ca Mg / L 283.5 ICP

According to the present invention, the liquid active mineral is impregnated into a sheet and dried to prepare an active mineral-containing sheet for sanitary ware. The sheet may be, for example, a material such as a nonwoven fabric, a pulp or the like commonly used in the art, and the impregnating and drying process may be any one generally applicable in the art, and is not particularly limited thereto.

The amount of the active mineral in the liquid phase contained in the containing sheets (40, 50) is suitably from 5 to 20 ml / m 2 in terms of economy and efficiency.

Meanwhile, the active mineral-containing sheet according to one embodiment of the present invention can be applied to sanitary articles such as sanitary napkins, tampons, and the like. 2, the pad type sanitary napkin 200 includes a liquid impervious sheet 10, an absorbent pad 20 formed on the impermeable sheet 10, And a liquid permeable sheet (30) formed on the active mineral-containing sheet (40) and the active mineral-containing sheet (40). 3, the tampon 300 includes an active mineral-containing sheet 50, an absorber 51 surrounding the outside of the sheet 50, and a removing strap 52 connected to the absorber 51 .

As described above, the far-infrared radiation-activating mineral-containing sheet for sanitary articles manufactured by the method of the present invention has an 80 Ion / cc or more anion by the KICM-FIR-1042 test method, And 3.44 x 10 < ² > W / m < ² > or more. These values of anion, emissivity and radiant energy mean that the sheet produced by the method according to the present invention is treated with active minerals emitting far-infrared rays.

Also, in the present invention, the sanitary article may include, for example, a pad-type sanitary napkin, a tampon, a cotton sanitary napkin, a panty liner or a diaper, but is not limited thereto.

Such an active mineral-containing sheet for sanitary articles having such a function can be used for various kinds of protein decay contained in human excreta such as menstrual blood, feces, urine and the like, as well as for removing odors such as ammonia, hydrogen sulfide and mercaptan, , Vulva, penis, or anus, and inhibits the proliferation of various bacteria that cause itching, and can have the effect of decreasing menstrual pain especially in women by far-infrared radiation effect.
