Description

Antifungal Antibacterial Antiviral Substrate Nonwoven Products, Antibacterial, Antimicrobial Nonwoven Product with Non antiseptic, Tissue, Diaper}

The present invention relates to a non-woven, antibacterial, antibacterial and antifungal non-woven fabric product and a method for producing the same. More particularly, the present invention relates to a non-woven fabric containing antifungal, antiviral, antiviral and non-woven fabrics applicable to nonwoven products such as wet tissues, diapers, And a method for producing the same.

Nonwoven products such as diapers, wipes, creasing tissues and sanitary napkins function in contact with human skin.

Conventional nonwoven products in contact with the skin include preservatives to prevent fungi or germs from being generated. Such preservatives are volatile alcoholic chemicals and have a characteristic odor. Therefore, a separate artificial fragrance is used to remove the odor of the preservative, which is not good for the human body.

Further, since the preservative is alcohol-based, it is volatilized when exposed to air exposed to the air. Accordingly, there arises a problem that the preservative ability is deteriorated if it is used for a long period of time. In order to solve this volatility problem, it is possible to add oil other than the preservative, but in this case, the mucous membrane of the skin is damaged.

In addition, various antiseptics should be added to remove various harmful substances such as fungi, viruses, and bacterial bacteria.

Due to the risk of such artificial preservatives, many companies feel the necessity of replacing artificial preservatives, but they are not commercialized due to the fact that they are not expensive in price and lack of technology. In recent years, a product using a natural extract having a preservative effect has been developed. However, in the case of a natural active substance, commercialization is particularly difficult due to coloring, deterioration of stability, narrow spectrum of antimicrobial spectrum, However, only a small amount of hinokitiol, Magnolol extract, Magnolol extract, and DF-100 extract, have been commercialized, but their preservative performance is insignificant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an anti-fungal antibacterial antiviral non-woven fabric product according to an embodiment of the present invention and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.

1 shows a diaper 2 as an example of a nonwoven product 1 according to a preferred embodiment of the present invention. Figure 2 shows a wet tissue 6 as another example of a nonwoven product 1 according to a preferred embodiment of the present invention.

1 and 2, a nonwoven fabric product 1 according to a preferred embodiment of the present invention includes an aqueous solution 200 of a nano zinc zeolite and a nonwoven fabric 3.

The nano zinc zeolite aqueous solution 200 is composed of water 150 and a zinc zeolite catalyst 100 having a size of 1 nm to 990 nm mixed with the water 150.

Zeolites are collectively referred to as minerals which are hydrates, and have porous crystals made of silicon (Si) and aluminum (Al). More specifically, the zeolite has an Alumino-Silicate structure in which the basic structure of SiO ₄ ^4- and AlO ₄ ^{5 -} tetrahedra is connected with oxygen and is three-dimensionally connected indefinitely. The zeolite is a zeolite of 1g to 500m ² as a crystalline material, such as the It has a surface area of 900m ² , has a high contact surface, and has pores of the same shape and size.

When the zeolite is replaced with an electron exchange type catalyst and diluted with water, it is safe to the human body and facilitates electron transfer to cause redox reaction, and the adsorption and removal are continuously repeated through binding and decomposition. As a result, Bacteria and the like causing the disease are adsorbed and decomposed to have a continuous antibacterial and deodorizing effect. This is called zinc zeolite.

The zinc zeolite catalyst 100 has a size of nano unit. The nano-unit zinc zeolite catalyst is not harmful to the human body, can mix well with water, and does not fall off when attached to a nonwoven fabric.

The zinc-zeolite catalyst (100) of nano unit is excellent in antimicrobial, antiviral, antifungal and deodorizing effect, and the duration of the effect is unexpectedly long. In this case, when each particle size of the zinc zeolite is 1 nm to 990 nm, the antibacterial and deodorizing effect is excellent and the duration thereof is also long.

The zinc-zeolite catalyst (100) of the nano unit is simultaneously subjected to antibacterial, antiviral, antifungal, and anti-seizing. Therefore, the use of a separate preservative is unnecessary.

The zinc zeolite catalyst (100) is mixed with water (150). In this case, the zinc zeolite catalyst 100 may have a structure in which a zinc zeolite catalyst is inserted into the water (150) particles. Through this, the zinc zeolite may not easily fall out from the nonwoven fabric.

In this case, the weight ratio of the water 150 and the zinc zeolite catalyst 100 is preferably 500 g to 5000 g per 1 g of zinc zeolite. The antimicrobial, anti-wrinkle, and antiviral effects are maximized when diluted with the above weight. In this case, when the amount of water is more than 5000 g per 1 g of zinc zeolite, a high concentration nano zinc zeolite aqueous solution 200 is not produced, and in particular, the effect can not be exhibited in the diaper 2 or the like.

If the amount of water is not more than 500 g per 1 g of the zinc zeolite catalyst, the zinc zeolite catalyst may be aggregated. In this case, the surface tension of the zeolite catalyst may be decreased and the performance may deteriorate. In addition, a nozzle clogging phenomenon may occur at the time of spraying.

In the case of a diaper, it is more preferable that the ratio of the zinc zeolite catalyst 100 to the water 150 is 900 g to 1100 g per 1 g of the zinc zeolite catalyst.

On the other hand, it is preferable that the zinc zeolite catalyst particles have a pro-best guide crystal structure as shown in Fig. The probest structure may have a structure in which a diamond crystal surrounds a cubic crystal and a net crystal surrounds the cubic crystal. When the catalyst has the above-described crystal structure, the ability to replace the catalyst is improved.

In this case, as shown in Fig. 1, the nonwoven fabric product 1 may be the diaper 2. In the case of the diaper 2, it is not necessary for the nano-zeolite aqueous solution 200 to be adhered to the portion not exposed to the human body, and the nano-zeolite aqueous solution 200 needs to be contained only in a part of the diaper. Also, it should not feel wet. Therefore, it is necessary to uniformly contain a small amount of a high concentration nano zinc zeolite aqueous solution 200.

In this case, the nano-zeolite zeolite aqueous solution 200 may be injected by a nozzle. The nano zinc zeolite is a nano unit. Therefore, it can be mixed with water at a high concentration. In addition, the spraying process can be performed as a nano unit, and no clogging occurs in the nozzle tube.

Alternatively, as shown in FIG. 2, the nonwoven product 1 may be a wet tissue 6. In this case, the wet tissue 6 is dipped or sprayed into water and is accommodated in the tissue housing 7. In this case, when the wet tissue 6 is dipped in water of 3 to 5 times the weight of the wet tissue 6 . It should be noted that the nonwoven fabric 1 of the present invention is not limited to a wet tissue or a diaper. The nonwoven fabric 1 of the present invention includes a sanitary napkin, a gauze, and the like, .

FIG. 4 is a block diagram illustrating a method of manufacturing an antimicrobial antiviral nonwoven product according to an embodiment of the present invention. Referring to FIG.

As shown in FIG. 4, a method (S10) for producing an antibacterial and antiviral nonwoven fabric product according to a preferred embodiment of the present invention comprises the steps of: preparing a zinc zeolite catalyst by substituting an electron exchange type catalyst in a zeolite powder (S12) a step of atomizing the zinc zeolite catalyst to prepare a liquid zinc zeolite having a particle size of 1 nm to 990 nm, and a step of diluting the liquid zinc zeolite with a solvent to prepare an aqueous solution 200 of a nano-zeolite zeolite (S13), and impregnating the nano-zeolite zeolite aqueous solution (200) by dipping or spraying the non-woven fabric (S14).

Each step will be described in more detail. As shown in FIG. 2, a step of preparing a zinc zeolite catalyst 100 by replacing an electron-exchangeable catalyst 120 with a zeolite powder 110 is carried out.

The zeolite is capable of supporting a metal or a metal oxide. Therefore, instead of aluminum or silicon, a metal such as silver (Ag), copper (Cu), iron (Fe), cobalt (Co), manganese (Mn), zinc (Zn), titanium (Ti), magnesium (Mg) ), Palladium (Pd), zirconium (Zr) or rhodium (Rh) may be substituted.

Metal ions, such as silver and copper, have strong antimicrobial effects, but they are not easy to use solely to react to various chemicals. That is, if it is provided to the human body, it may adversely affect cell membrane entry or interfere with cell metabolism. Therefore, by replacing at least one or more metals such as silver and copper in the zeolite, the metal is not simply mixed but becomes a part of the zeolite, so that the zeolite does not react with the chemical substance, and the metal ion is converted into antibacterial, antifungal, An anti-seizing effect can be obtained. The zinc zeolite catalyst 100 can be prepared by dipping the zeolite powder 110 into the liquid phase electron-donative catalyst 120.

In this step, the zinc zeolite catalyst 100 may be firstly pulverized. When the zinc zeolite catalyst (100) is pulverized, the viscosity of the zinc zeolite catalyst (100) becomes high. Crushing the zinc zeolite catalyst (100) having a higher viscosity with stirring produces a more uniform zinc zeolite catalyst (100).

The zinc zeolite catalyst 100 is preferably aged for a predetermined time, for example, 2 to 3 days. The degree of substitution of the liquid phase electron-donative catalyst 120 with the zeolite powder 110 is improved by the above aging.

Thereafter, as shown in FIG. 4, the zinc zeolite catalyst 100 is finely processed so that the respective particle sizes become 1 nm to 990 nm. The above step is a step of preparing a liquid zinc zeolite (not shown) in which the atomized zinc zeolite catalyst 100 and the liquid solvent for atomization are mixed. That is, when the particle size of the zinc zeolite catalyst 100 is reduced to 1 nm to 990 nm, the particle size of the zinc zeolite catalyst 100 in contact with the periphery becomes large, thereby maximizing the antibacterial antifungal antiviral anti-wrinkle effect.

To this end, the zinc zeolite catalyst 100 is first mixed with the crusher 60 in the storage tank 210. The pulverizer 60 may be titanium, diamond, or the like, and the size thereof may be 0.05 mm to 0.5 mm. In addition, the zinc zeolite catalyst 100 is in a semi-solid state, and a certain amount of the liquid solvent 50 may be mixed for wet processing.

In this case, the mixing can be performed in the storage tank 210, and the stirring tank is installed in the storage tank 210 so that the zinc zeolite catalyst 100 can be mixed with the crusher 60 without being hardened .

Thereafter, the zinc zeolite catalyst 100 mixed with the crusher 60 is moved to the processing tank 220 and subjected to nano-processing to atomize the catalyst. In this step, the crusher (60) is agitated by the agitator (222) to the zinc zeolite catalyst (100). Then, the crusher 60 crushes the particles constituting the zinc zeolite catalyst 100 in nanoseconds. In this case, it is preferable that the pressure is important factor in the crushing, so that the pressure gauge 224 is installed in the processing tank 220. In this case, it is preferable that pressure is not applied to the reservoir by pressure regulation.

The atomized zinc zeolite catalyst 100 is moved to the back pressure regulating tank 230 to adjust the pressure of the gas entering the processing tank 220 and the pressure exiting the processing tank 220. In this case, the back pressure regulating tank 230 is provided with a motor 232 to regulate the back pressure.

A nanofilter 226 may be disposed between the back pressure control tank 230 and the processing tank 220. The nanofilter 226 continues to be atomized in the processing tank 220 without passing particles having a size of 990 nm or more among the substances passing through the nanofilter 226.

The processing step may be performed in a single cycle. However, by continuously transferring the zinc zeolite catalyst 100 into the storage tank 210, the processing tank 220, and the back pressure regulating tank 230, the liquid zinc zeolite having a more preferable size can be obtained by repeating several cycles to tens of thousands of cycles. Can be manufactured.

It is preferable that each particle size of the liquid zinc zeolite produced through such nano processing is in the range of 1 nm to 990 nm. If each of the particles constituting the liquid zinc zeolite is larger than 990 nm, the antibacterial deodorizing effect is insufficient, and the liquid zinc zeolite Is less than 3 nm, the liquid zinc zeolite may penetrate into the skin and may be unfavorable to human health.

Antifungal, antiviral, antifungal and deodorizing effects are excellent when the zinc-zeolite catalyst (100) substituted with the electron affinity catalyst (120) is atomized in nano unit, and the duration of the effect is unexpectedly long . In this case, when the particle size of the liquid zinc zeolite is in the range of 1 nm to 990 nm, the antibacterial deodorizing effect is excellent and the duration thereof is also long.

Thereafter, the liquid zinc naphtha zeolite aqueous solution 200 is completed (S13) by diluting the liquid zinc zeolite with a water solvent.

In the above step, the receiving medium may be pure water, distilled water, or water of pH 7 to 8 or distilled water may be used. Further, the liquid zinc zeolite may be dissolved in a water solvent

0.1 wt% to 10 wt%, based on 1 g, of the zeolite zeolite catalyst (d) is preferably 1 nm to 990 nm.

The nano-zeolite zeolite aqueous solution 200 produced by the above-described method has a particle size of 1 nm to 990 nm. In this case, the ceramic functions to collect bacteria, and the electron affinity catalyst 120 functions to decompose the bacteria and odor. That is, by substantially decomposing bacteria, antibacterial and deodorization can be fundamentally achieved.

When the zeolite particles substituted with the electron affinity catalyst 120 are cleaved into 1 nm to 990 nm nano units, the antibacterial and deodorizing effect is excellent and the effect retaining time is also unpredictable, for example, about 3 months .

Accordingly, it is advantageous in that it has a shorter effect holding time and is superior in function and effect to the conventional liquid antimicrobial deodorant used for removing odors, and has a merit that the maintenance cost can be reduced in comparison with the conventional air purifier. It is also made of inorganic materials that are not corrupted and do not become a secondary source. In addition, it can adsorb and decompose fungi that cause fungi and bacterial diseases, and can achieve an air cleaning effect close to the natural state.

 Thereafter, the step (S14) of dipping or spraying the nano zinc zeolite aqueous solution (200) onto the nonwoven fabric is performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
