The main purpose of the present invention is to provide wet tissues that emit far-infrared rays and exhibit antibacterial properties.

In one aspect, the present invention provides a wet tissue containing 0.1 to 10 parts by weight of fatty acid based on 100 parts by weight of fabric for wet tissues.

In the wet tissue of the present invention, it is preferable to further include 0.001 to 10 parts by weight of at least one selected from theaflobin and catechin based on 100 parts by weight of the wet tissue fabric.

In another aspect, the present invention provides a wet tissue containing 0.001 to 10 parts by weight of at least one selected from theaflobin and catechin based on 100 parts by weight of wet tissue fabric.

The present invention, as a result of discovering and studying the mechanism of action by which fatty acids emit far-infrared rays beneficial to the human body and exhibit antibacterial properties, includes these fatty acids in fabric for wet wipes, for example, synthetic resin fabric for wet wipes, thereby emitting far-infrared rays. It was developed based on the results of confirming that it was possible to obtain wet tissues that radiate and exhibit antibacterial properties.

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

Saturated fatty acids are fatty acids that contain single fatty acid bonds. Saturated fatty acids are abundant in animal fats, have high melting points, and mostly exist as solids.

Unsaturated fatty acids are abundant in fish and vegetable fats, have a low melting point, and exist as a liquid 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).

There are three types of molecular structures of common omega-3 fatty acids.

There is a TG (triglyceride) type made up of saturated and unsaturated fats and is extracted from fish. Since it has a structure in which two saturated fats and one unsaturated fat are combined in one glycerol molecule, there is a problem in that the purity of the unsaturated fatty acid omega-3 (EPA, DHA) component is as low as about 33%. There is an EE (ethyl ester) type. Ethanol is added to the fat extracted from fish, and the fatty acids are separated through distillation. It has a structure in which one saturated fat is combined with one ethanol molecule and two unsaturated fats are combined with two ethanol molecules, so it is an omega-3 fatty acid (EPA, Although the purity of DHA can be increased to about 70%, there is a problem that ethanol remains. 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, thereby improving the purity of omega-3 fatty acids (EPA, DHA). Although it can be concentrated up to 100%, it has the problem of requiring excessive manufacturing costs.

In the present invention, it is preferable to use omega-3 fatty acids, omega-9 fatty acids, and/or omega-6 fatty acids as fatty acids, and the higher the purity, the higher the antibacterial properties and the higher far-infrared radiation rate. For example, polypropylene wet tissues containing 0.1 to 5 parts by weight (relative to 100 parts by weight of wet tissue fabric) of omega-3 fatty acids with a purity of 50 to 75% had a far-infrared emissivity (5) at 37°C in the KFIA-F1-1005 test. ~ 20μm) 0.884, and in the KFiA-F1-1003 test, the initial concentration of E. coli (CFU-ml) was 8.8x10 ~ the bacteriostatic reduction rate of E. coli was 87(%), and the initial concentration of Staphylococcus aureus (CFU-ml) was 1.6x10⁴ reduction rate 78.7(%). Polypropylene wet tissues containing 0.1 to 5 parts by weight (relative to 100 parts by weight of wet tissue fabric) of omega-3 fatty acids with a purity of 85 to 95% had a far-infrared emissivity (5 to 20 μm) of 0.885 at 37°C in the KFIA-F1-1005 test. In the KFiA-F1-1003 test, the initial concentration of E. coli (CFU-ml) is 8.8x10 ~ E. coli bacteriostatic reduction rate is 95 (%), the initial concentration of Staphylococcus aureus (CFU-ml) is 1.6 x 10⁴ ~ 94 (%), and the purity is 95 ~ 99. Polypropylene wet tissues containing 0.5 to 5 parts by weight (relative to 100 parts by weight of wet tissue fabric) of .% omega-3 fatty acids had a far-infrared emissivity (5 to 20 μm) of 0.887 at 37°C in the KFIA-F1-1005 test, and E. coli and With a salmonella bacteriostatic reduction rate of 99.9%, the purity of omega-3 can be confirmed to be proportional to the far-infrared radiation rate and antibacterial properties, so skilled technicians in the art know that the purity of omega-3 fatty acids must be appropriately controlled. Omega-6 and omega-9 fatty acids have similar effects to omega-3, so they can be mixed appropriately.

Omega-9 fatty acid, a monounsaturated fatty acid, is a series of fatty acids in which the 9th carbon from the methyl end of the fatty acid has a double bond and is also called oleic acid, and salts and esters of oleic acid are called oleate. Because oleic acid contains only one double bond, it is more difficult to oxidize lipids compared to linoleic acid and linolenic acid, which are polyunsaturated fatty acids. It is contained in large quantities as the main ingredient in olive oil and canola oil (rapeseed oil).

Omega-6 fatty acids are fatty acids that have two cis double bonds in a chain of 18 carbons. Also called linoleic acid, it acts as a precursor for the biosynthesis of other omega-6 fatty acids. Omega-6 fatty acids include arachidonic acid and gamma (γ)-linolenic acid. Linoleic acid is used to make a drying oil useful in oil-based paints and varnishes. It has anti-inflammatory, 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 large quantities in salicornia oil, evening primrose oil, melon seed oil, corn oil, grape seed oil, sunflower seed oil, soybean oil, and olive oil. In the present invention, fatty acids may contain polyphenol catechin or theaflavin to inhibit lipid peroxidation and increase antibacterial properties since lipid peroxidation occurs.

Catechin is contained in large amounts in green tea. Oolong tea is made by fermenting about 20% to 65% of green tea, and black tea is made by fermenting about 85% or more. During fermentation, catechin is oxidized and theaflavin is produced. Catechin is oxidized to become quinone, and when two quinones come together, it becomes theaflavin.

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

The antiviral and antibacterial mechanisms of action of catechin, theaflavin from black tea extract, theaflavingallate, and their derivatives have been known for a long time. Research results showing that catechin and theaflavin contained in black tea extract are effective against severe acute respiratory syndrome (SARS-CoV) have also been published several times in related academic circles, and on March 10, 2020, in the world-famous Journal of Medical Virology. It was posted. Theaflavin, theaflavin-3-gallate, theaflavin-3'-gallate, theaflavin-3 produced from catechin, 3'-Digallate (theaflavine-3,3'digallate) has been reported to have an excellent antiviral effect, and research results have also been published showing that the antiviral effect of theaflavine is more powerful than that of catechin.

In the general wet tissue manufacturing process, the manufacturing process involving moisture is a known technology and detailed description will be omitted.

In the present invention, the method of incorporating fatty acids into wet tissues includes, for example, omega-3 fatty acids with a purity of 80 to 99%, omega-6 fatty acids with a purity of 80 to 99%, and omega-6 fatty acids with a purity of 80 to 99% based on 100 parts by weight of polypropylene-based synthetic resin fabric. One or more types of omega-9 fatty acids can be selected and included in an amount of 0.1 to 10 parts by weight, for example, by coating or impregnating wet tissue fabric.

Preferably it contains 0.1 to 5 parts by weight, more preferably 0.1 to 3 parts by weight, more preferably 0.1 to 2 parts by weight, more preferably 0.5 to 1.5 parts by weight, more preferably 1 to 1.2 parts by weight. It may include weight parts. Meanwhile, one or more types of catechin and theaflobin (based on solid content) may be selected and included in an amount of 0.001 to 10 parts by weight, preferably 0.001 to 5 parts by weight, more preferably 0.001 to 3 parts by weight, based on 100 parts by weight of synthetic resin fabric. Parts by weight, 0.001 to 2 parts by weight, more preferably 0.1 to 3 parts by weight, more preferably 0.1 to 2 parts by weight, more preferably 0.5 to 1.5 parts by weight, more preferably 1 to 1.2 parts by weight. . Catechin and theaflobin prevent oxidation of fatty acids and form antibacterial and antiviral properties in wet tissues. For example, it can be added to fatty acids, or it can be included by adding it to moisture and impregnating it in the wet tissue manufacturing process. In the present invention, the method of including fatty acids, catechin, and theaflobin in wet tissues may vary and is not limited to the above. There are no restrictions on the method as long as it is a purpose that can be included in wet tissues. For example, catechin can be included by adding it to fatty acid, and can be included by adding it to ethyl alcohol or water.

When one or more selected from fatty acids and/or catechins and theaflobins are included in wet tissue fabrics at the level (amount) suggested herein, the wet tissues can economically exhibit a high far-infrared ray radiation effect and a high antibacterial effect.
