One aspect of the present application, comprising the steps of: preparing a first mixed fiber mixed with polyester and rayon fibers in a weight ratio of 5:1 to 1:1; preparing a second mixed fiber by extracting pulp fibers from a mixture of bamboo wood chips, birch wood chips and rice straw; dipping the first mixed fiber in an oil mixture containing ginkgo oil, cypress oil and tea tree oil, followed by drying; preparing a tissue after mixing the first mixed fiber and the second mixed fiber in a weight ratio of 9:1 to 4:1; preparing a disinfectant solution by mixing purified water and a disinfectant stock solution; immersing the tissue in the disinfectant solution; and packaging the tissue. It provides a method for producing a tissue for sterilization and disinfection, comprising a.

Hereinafter, a method of manufacturing a tissue for sterilization and disinfection according to an embodiment of the present invention may be described with reference to FIG. 1 .

First, polyester and rayon fibers are mixed in a weight ratio of 5:1 to 1:1 to prepare a first mixed fiber. A method of mixing the fibers in the first mixed fiber manufacturing step may use a conventional fiber blending method.

The polyester has the second strongest fiber strength after nylon when pulled, and the strength does not change when wet. In particular, the degree of wrinkle recovery is as good as that of wool, and the degree of recovery when wet is even higher. It has low hygroscopicity, little elasticity, and a very high drying rate, so it can be washed and worn immediately, making it suitable as a material for a shirt. In addition, since it is a short fiber and has properties similar to wool, it can be used as a material for men's suits and suits by being blended with wool or other yarns.

The rayon is made by treating wood or cotton shavings with a suitable chemical method to make pulp made of pure cellulose, chemically dissolving it, and then coagulating it into a fibrous form. has the characteristics of

Next, pulp fibers are extracted from a mixture of bamboo wood chips, birch wood chips and rice straw to prepare a second mixed fiber. The process of extracting pulp fibers from the bamboo wood chips, birch wood chips and rice straw mixture may be performed in a conventional pulp manufacturing process.

The bamboo fiber extracted from the bamboo wood chips is a fiber extracted by wet spinning bamboo, and is an eco-friendly material that is harmless to the human body and has a mold inhibitory function, and has good absorbency and deodorization properties.

The birch fibers extracted from the birch wood chips are mainly used for manufacturing paper, and are characterized by high durability.

The rice straw fiber extracted from the rice straw is a fiber mainly used for paper or heat insulating clothing, and is characterized by little elasticity and a very high degree of drying.

In one embodiment, the bamboo wood chips, birch wood chips and rice straw mixture may be mixed with bamboo wood chips, birch wood chips and rice straw in a weight ratio of 6-8: 2-1: 2-1.

Next, the first mixed fiber is immersed in an oil mixture containing ginkgo biloba oil, cypress oil and tea tree oil and then dried.

The ginkgo oil is extracted from the oil of ginkgo biloba and ginkgo leaves and exhibits sterilization and antibacterial action.

The cypress oil is extracted from the oil of the cypress tree and exhibits skin irritation relief and sterilization action.

The tea tree oil is extracted from tea tree oil and exhibits antibacterial and skin disease prevention effects.

In one embodiment, the oil mixture may be a mixture of the ginkgo oil, cypress oil, and tea tree oil in a weight ratio of 1: 1-3: 1.

Next, after mixing the first mixed fiber and the second mixed fiber in a weight ratio of 9:1 to 4:1, a tissue is prepared. If the mixing amount of the second mixed fiber compared to the first mixed fiber is less than the weight ratio of 9:1, the characteristics of natural pulp fibers may not appear, and if it is higher than the 4:1 weight ratio, the softness of the tissue may be reduced.

The tissue manufacturing method may use a non-woven fabric manufacturing method or a fabric manufacturing method, preferably using a non-woven fabric manufacturing method. The nonwoven fabric does not weave or weave using a yarn like a fabric, but rather arrange the fibers appropriately and directly use the adhesive or the fusion force of the fibers or the entanglement of the fibers to produce the same form as a fabric, It may be prepared by bonding mechanically, chemically, thermally or by solvent treatment.

For example, the nonwoven fabric manufacturing method is largely divided into wet nonwoven fabric and dry nonwoven fabric. The wet nonwoven fabric includes spunbond nonwoven fabric, spunlace nonwoven fabric, melt blown nonwoven fabric, heat fusion nonwoven fabric, etc., and dry nonwoven fabric includes dry laminated nonwoven fabric, needle There are punching non-woven fabrics, stitch-bonding non-woven fabrics, chemical bonding non-woven fabrics, and the like.

In the tissue manufacturing step, the tissue may be prepared as a cleaning cloth if necessary.

Next, a disinfectant solution is prepared by mixing purified water and a disinfectant stock solution.

The disinfection means annihilation of pathogens for the purpose of preventing the transmission of infectious diseases, and the methods of disinfection include incineration, sunlight disinfection, steam disinfection, boiling (煮沸) disinfection, drug disinfection, and the like.

In one embodiment, the disinfectant solution is benzalkonium chloride or sodium hypochlorite, and the disinfectant stock solution may contain 0.05 to 0.2% by weight based on 100% by weight of the disinfectant solution.

The benzalkonium chloride is a nitrogen cationic surfactant belonging to a quaternary ammonium salt, and is well soluble in ethanol and acetone. Benzalkonium chloride is poorly soluble in water, but an aqueous solution is preferred because it is easy to handle. The solution has a pH of 6.5-8, and the color is colorless or pale yellow. It is mainly used as a disinfectant, cationic surfactant and phase transfer catalyst.

The sodium hypochlorite (sodium hypochlorite) is one of the hypochlorite salts made by using chlorine gas in a sodium hydroxide solution, etc. Oxygen is generated by a reaction in water and cyanic acid present in the wastewater is made into cyanic acid by using oxygen. After that, cyanic acid is decomposed again into nitrogen and carbon dioxide to make it harmless. The lower the pH, the stronger the sterilizing power, and the sterilizing power is reduced by proteins, sugars, amino acids, etc. The sterilizing power is the highest when the pH is adjusted to 8-9 after dilution to a concentration of 100 ppm. Sodium hypochlorite is a pale greenish-yellow or colorless liquid with a chlorine odor. If the aqueous solution is stored for a long time, it is decomposed and converted into chlorine gas, thus losing its effectiveness as a disinfectant. Also, since it is highly corrosive, it should not come into contact with metal containers. It is mainly used as a disinfectant to remove spoilage bacteria or pathogens from food, and is used as a disinfectant, bleach, and oxidizing agent.

In an embodiment, the step of preparing the disinfectant solution may further include 0.1 to 1% by weight of silver powder and 0.1 to 0.5% by weight of baking soda based on 100% by weight of the disinfecting solution.

The silver powder can have a fatal effect on bacterial propagation through silver ions, and is widely used as an antibacterial component because it has excellent antibacterial effect even with a very small amount of silver ions. For example, silver nano ingredients are added to sportswear, hiking clothes, underwear, and socks that get wet frequently, or silver nano ingredients are added to synthetic detergents for laundry or fabric softeners used after washing. Silver-coated activated carbon is sometimes used to prevent bacterial propagation in activated carbon filters or ion exchange filters of water purifiers, and medical devices such as airway intubation implanted or inserted into the human body or some implants are also coated with silver to prevent infection.

The baking soda, also called sodium bicarbonate, is an expanding agent mainly used to inflate sweets and bread to make it voluminous, but it has sterilization, deodorization and cleaning effects and is also used as a dishwashing detergent or laundry aid.

Next, the tissue is immersed in the disinfectant solution.

The immersion may use various immersion methods known in the prior art.

The immersion step may be replaced by a solution spraying method if necessary. In the solution spraying method, the prepared disinfectant solution may be sprayed onto the tissue using an application device equipped with a spray nozzle or the like.

Finally, the tissue is packaged to obtain a tissue for sterilization and disinfection.

Another aspect of the present application provides a tissue for sterilization and disinfection prepared by the above manufacturing method.

2, the prepared sterilizing and disinfecting tissue can be seen.
