An object of the present invention is to obtain a wet tissue formed with far-infrared rays and antibacterial properties, which includes at least one selected from fatty acids and catechin or theaflobin.

The present invention discovered a mechanism of action in which fatty acids emit near-infrared and far-infrared rays beneficial to the human body and form antibacterial properties.

Fatty acids can be classified into saturated fatty acids and unsaturated fatty acids. Their chemical structure is a long chain with 4 to 24 carbon atoms, in the form of a hydrocarbon tail with carboxyl groups (-COOH) and methyl groups (-CH3) at both ends.

Saturated fatty acids are fatty acids with single fatty acid bonds. Saturated fatty acids are found in animal fats, have high melting points, and are mostly solid.

Unsaturated fatty acids are abundant in fish and vegetable fats, have low melting points, and exist as liquids at room temperature. For example, omega-3 fatty acids are unsaturated fatty acids and are composed of linolenic acid, EPA (Eicosapentaenoic acid), and DHA (Docosahexaenoic acid). The molecular structure of omega-3 fatty acids has three forms

There is a TG (Triglyceride) type composed of saturated and unsaturated fats, and it is extracted from fish. It has a structure in which two saturated fats and one unsaturated fat are combined in one molecule of glycerol, so the purity of unsaturated fatty acid Omega-3 (EPA, DHA) is high. There is a problem as low as 33%, and there is an EE (ethyl ester) type. Ethanol is added to fat extracted from fish, and fatty acids are separated through distillation. Since one molecule of ethanol is combined with one saturated fat and two molecules of ethanol are combined with two unsaturated fats. Although the purity of omega-3 fatty acids (EPA, DHA) can be increased to about 70%, there is a problem of remaining ethanol.

The rTG (Altige) type is an improvement on the problems of the EE type. The EE type is re-esterified and 3 unsaturated fatty acids are combined with 3 glycerol molecules, improving the purity of omega-3 fatty acids (EPA, DHA). It can be concentrated up to 100%, but there is a problem in that excessive manufacturing costs are required

As for the fatty acids used in the present invention, it is preferable to use omega-3 fatty acids, omega-9 fatty acids, and omega-6 fatty acids. The higher the purity, the higher the antibacterial properties and far-infrared radiation. ~ 5 parts by weight of the polypropylene wipes had a far-infrared ray emissivity (5-20 μm) of 0.884 at 37°C in the KFIA-F1-1005 test, and an initial concentration of E. coli (CFU-ml) of 8.8x10 ~ E. coli bacteriostatic reduction in the KFiA-F1-1003 test 87 (%), Staphylococcus aureus initial concentration (CFU-ml) 1.6x10⁴ reduction rate 78.7 (%)

The polypropylene-based wet tissue containing 0.1 to 5 parts by weight of omega-3 fatty acid with a purity of 85 to 95% has a far-infrared ray emissivity (5 to 20 μm) of 0.885 at 37 ° C in the KFIA-F1-1005 test, and the initial concentration of Escherichia coli in the KFiA-F1-1003 test ( CFU-ml) 8.8x10 ~ Escherichia coli bacteriostatic reduction rate 95 (%), Staphylococcus aureus initial concentration (CFU-ml) 1.6x10⁴ ~ 94 (%)

The polypropylene wet tissue fabric containing 0.5 to 5 parts by weight of omega-3 fatty acids with a purity of 95 to 99.% has a far-infrared emissivity (5 to 20 μm) of 0.887 at 37 ° C in the KFIA-F1-1005 test, and a bacteriostatic reduction rate of Escherichia coli and Salmonella is not detected by 99.9%. Therefore, it can be confirmed that the purity of omega 3 is proportional to the far-infrared emissivity and antibacterial properties.

Those skilled in the art know that the purity of omega-3 fatty acids must be appropriately controlled. Since omega-6 and omega-9 fatty acids have similar actions to omega-3, they can be appropriately mixed.

Omega-9 fatty acids, which are monounsaturated fatty acids, are a series of fatty acids having a double bond at the ninth carbon from the terminal of the methyl group of the fatty acid, and are also called oleic acid, and salts and esters of oleic acid are called oleates. Since oleic acid contains only one double bond, it is difficult to oxidize lipids compared to polyunsaturated fatty acids, linoleic and linolenic acids, and is contained in large amounts as a main component in olive oil and canola oil (rapeseed oil).

Omega-6 fatty acids are fatty acids with two cis double bonds in an 18-carbon chain, also called linoleic acid, and serve as a precursor for the biosynthesis of other omega-6 fatty acids. Arachidonic acid gamma as an omega-6 fatty acid (γ)-linolenic acid, etc. Linoleic acid is used to make a drying oil useful for oil paints and varnishes. It has anti-inflammatory and acne-reducing, skin-whitening and moisturizing properties. When reduced, it produces linoleyl alcohol and is easily soluble in acetone and ethanol It is contained in corn oil, evening primrose oil, melon seed oil, corn oil, grape seed oil, sunflower seed oil, soybean oil, and olive oil.

In the present invention, since lipid peroxidation occurs in fatty acids, polyphenols such as catechin or theaflavin may be included to suppress lipid peroxidation and increase antimicrobial activity.

Green tea contains a large amount of catechin. About 20% to 65% of green tea is fermented as oolong tea, and about 85% or more fermented as black tea. During the fermentation process, catechin is oxidized and theaflavin is produced. When two quinones come together, they form theaflavins.

When green tea is fermented for 90 minutes, epigallocatechin gallate is reduced by about 98% and produced as theaflavin, so green tea extract alone can be used or mixed with black tea extract.

The antiviral and antibacterial mechanism of action of catechins and black tea extract's theaflavin, theaflavingallate and their derivatives has been known for a long time. The research results that theaflavin is effective have also been published several times in related academic circles and have been published in the world-class medical virology journal (Journal of Medical Virology) on March 10, 2020. Theaflavin-3-gallate (theaflavin-3'-gallate) Theaflavine-3,3'-digallate (theaflavine-3,3'-digallate) is an excellent antiviral It has been announced that it is effective, and research results have also been announced that theaflavin has a stronger antiviral action compared to catechin.

In the manufacturing process of general wet wipes, the manufacturing process containing water is a well-known technology, so detailed descriptions will be omitted.

In the present invention, the method of including fatty acids in wet tissues is, for example, 80 to 99% pure omega-3 fatty acids, 80 to 99% pure omega-6 fatty acids, and 80 to 99% pure omega based on 100 parts by weight of polypropylene synthetic resin fabric. One or more fatty acids may be selected and included in an amount of 0.1 to 10 parts by weight, for example, by coating or impregnating wet tissue fabric.

It preferably contains 0.1 to 5 parts by weight, more preferably 0.1 to 2 parts by weight. Meanwhile, catechin and theafrobin (based on solid content) may contain 0.001 to 10 parts by weight based on the synthetic resin fabric by selecting one or more. and preferably 0.001 to 5 parts by weight and more preferably 0.001 to 2 parts by weight. Catechin and theafrobin prevent oxidation of fatty acids and form antibacterial and antiviral properties in wet wipes. It can be added and impregnated by adding it to moisture in the wet tissue manufacturing process.

In the present invention, the method of including fatty acid and catechin theaflobin may vary and is not limited to the above. The method is not limited as long as it is a purpose that can be included in wet tissue. For example, catechin can be added to fatty acid and included, and ethyl Can be included by adding to alcohol or water

If the inclusion of fatty acids and catechin theaflobin in the wet tissue fabric is more than the above parts by weight, the improvement of physical properties is weak and uneconomical, and if less than that, the implementation of the purpose of the invention is insufficient.

Table 1 below shows the composition of vegetable fatty acids, and Table 2 shows the chemical formula of saturated fatty acids, omega-9 fatty acids, omega-6 fatty acids, and omega-3 fatty acids.

Table 3 below shows EGCG contained in green tea and black tea or its derivatives.

Table 4 below shows the theaflavins of green tea and black tea and their derivatives.

The present invention can contribute far-infrared rays to related industries by including fatty acids and catechin theaflobin, which are effective compositions of antiviral and antibacterial action in wet wipes.
