Method for manufacturing wet tissues using hemp}

The present invention relates to a method of manufacturing a wet tissue using hemp, and specifically, a wet tissue using hemp which is eco-friendly and has excellent antibacterial and sterilizing power because it can obtain the same effect as the existing antibacterial wet tissue while using an eco-friendly material with low toxicity to the human body. It relates to a manufacturing method.

The history of human beings collecting and using hemp fibers is from 2000 BC. The main types of hemp used are hemp, flax, hemp, and jute. is being used as These hemp fibers are used for medical purposes, and as summer clothing, heat dissipation is fast and does not sag. And it has great value as a material for painting.

Hemp is an annual plant, composed of a mixture of pectin, water, and soluble substances with 77 to 78% cellulose, and has a very unique structure in which long hollow pipes are entangled like a spider's web. Because of its structural characteristics, it not only has the properties of controlling moisture and heat, but also has various functions such as water absorption 20 times faster than cotton, discharging power, and soundproofing. The strength is 5~8 g/d, the elongation is 1.5~2%, which is 10 times stronger than cotton.

In addition, such hemp is used for various purposes such as fiber, pay, and medicine, but is mainly used for textiles in Korea. In addition, hemp fibers are used for fabrics, mosquito nets, tents, ropes, nets, matting threads, blends, etc., and seeds are used for seasoning or oil production. In addition, it is 100% completely organically decomposed during incineration, so it is very eco-friendly and widely used in various industrial fields, and technology development is in progress.

On the other hand, wet wipes are made by applying a liquid raw material to a fabric that is resistant to moisture, and are also called wet tissues.

These wet wipes are made of pulp or non-woven fabric, which is not easily decomposed despite containing moisture, as a material. At the same time, it is used to detoxify a human body or an object in direct contact with the human body.

In addition, chemical preservatives such as benzene series or carbamate series are mainly used for disinfection, antibacterial and sterilization components of these wet wipes to prevent the propagation of bacteria and mold in the process of packaging, distribution, and use. Proprene glycol, a moisture evaporation inhibitor, is also used to prevent it.

As described above, even if the amount of chemical preservatives conventionally used in wet tissues is less than the legally permitted standard amount, when used for a long period of time or used frequently or in a large amount at once, skin troubles, hormonal abnormalities, and allergic reactions are harmful to the human body. It has a harmful effect, and in particular, in the case of a child with delicate skin or a patient with a skin disease, it reacts more sensitively to the chemical preservative contained in the wet tissue, so there was a hassle to be very careful when using it.

Hereinafter, by explaining a preferred embodiment of the present invention, a method of manufacturing a wet tissue using hemp of the present invention will be described in detail.

In the method of manufacturing a wet tissue using hemp of the present invention, first, the leaves and/or stems of hemp are washed and then dried.

After storing the prepared dried hemp leaves and/or stems in a pressure-resistant container, the compressed extraction solvent is put into the pressure-resistant container, and the pressure-resistant container is heated. Then, after a certain period of time, the pressure-resistant container is opened to vaporize the compressed solvent and a pure extract can be obtained.

Here, various components contained in hemp can be effectively obtained by putting it in the heat-resistant and pressure-resistant container and heat-treating it. As an additional explanation, the pressure-resistant vessel maintains a vacuum inside, so that there is no internal material loss even if the temperature is raised from the outside. Therefore, it is possible to extract only the liquid by filtering impurities in order to collect the liquid obtained from the material by heating using the pressure-resistant vessel.

In addition, the extraction solvent input together with the mouth and/or stem of hemp to the pressure-resistant container is selected from among ethane, propane, carbon dioxide, ethanol, nitrous oxide, butane, isobutene, and dimethyl ether.

Thereafter, the extract constituted as described above is dissolved in purified water from which foreign substances and microorganisms are removed to obtain a mixture as a solution.

Thereafter, functional ingredients are added to this mixture. The functional ingredient is to add silver nano, tabasheer, and lacquer extract at a certain ratio, and all of these ingredients are substances with excellent antibacterial effect.

Let's take a look at each of the above functional ingredients.

Silver nano is made of silver powder with a size of 1 to 100 nm, and has excellent antibacterial properties. In the present invention, silver nanoparticles can be contained on the surface of the wet tissue in various ways, for example, by spray spraying through an air brush, or by applying silver nano powder to a brush or the like, or by mixing silver nanoparticles with a hemp mixture. It can also be spread. In addition, the application amount of the silver nano-powder is also not limited, for example, about 5 to 200 g of silver nano-powder per 1 m 2 of the textile fabric may be used. This means the actual amount of silver nano-powder remaining on the surface removed through post-processing. The method for producing the silver nano-powder is well known in the art to which this technology belongs, and the method is not limited thereto.

Illustratively, the silver nanoparticles applied to the present invention may be manufactured through the following process. First, one or more of a silver precursor, exemplarily silver acetate, and silver nitrate is dissolved in water and one or more solvents of alcohol having 1 to 4 carbon atoms, and then the prepared precursor solution is ultrasonically sprayed, spray nozzle sprayed by air, and pressure It is sprayed into fine droplets by any one of the nozzle spraying methods. Then, the sprayed droplets are transferred into a heating reactor or a flame reactor by at least one carrier gas of oxygen, nitrogen, and air, and decomposed by heating at a temperature of 400 to 2,000 °C. And by rapidly cooling it to 0 ~ 200 ℃ by a cooling fluid such as water, nitrogen or air, to prepare a uniform silver nano-powder with a small particle size.

Tabasheer (bamboo oil) is known to show an excellent effect when taken with ginger tea to treat and prevent vascular diseases or bronchial asthma. In oriental medicine, it has been critically used for paralysis and paraplegia since ancient times, and has been used to control blood pressure, purify blood, stop phlegm, and treat speech disorders and pain in limbs caused by stroke. It has an excellent antipyretic effect and shows an excellent effect in treating burns. If you apply tabasheer immediately after getting a burn, the pain disappears immediately, and if you continue to drain the tabasheer until the burning thing disappears, any burns will heal cleanly without blisters. In addition, it brightens the eyes, prevents hangovers, and facilitates all sensory organs and excretory functions of the human body. Because of its excellent sterilization effect, it is effective in treating various skin diseases, athlete's foot, eczema, and raw hands.

Lacquer extract is prepared using a cauldron at the ratio of 1000 g of lacquer tree or lacquer bark, 10,000 ml of water in a cauldron at the ratio of 1000 g of lacquer water, and 1,000 ml of lacquer dissolved in lacquer radish Add 1,000 ml of lacquer water at a ratio of 1,000 ml, and put 1,000 g of silver ionized water in the first step in a stainless steel stirrer for 1 hour at the ratio of 1,000 ml of uric water prepared above, and the silver nano solution is completely ionized in the extract A silver nano-extract solution coated in the form is prepared.

Lacquer has excellent antibacterial and anticancer effects, and this effect has been proven in various scientific journals. However, the fact that lacquer cannot be freely used for food is toxic to urushiol and causes allergies. However, if urushiol, which is poisonous from lacquer, is removed and used, there is no side effect as described above. In order to eliminate the side effect, a compound made by burning urushiol at a high temperature is used to remove urushiol, a toxic substance.

Finally, the fabric of the wet tissue is immersed in the solution to which the hemp mixture and the functional ingredient are added to produce a wet tissue.

The wet tissue fabric is prepared by selecting at least one of waste tissue paper, crushed pulp waste, cotton pulp waste, wood pulp waste, recycled pulp waste, and pulp material recovered by a wet method from synthetic resin fiber waste, and has a basis weight of 30 to 100 gsm (g/ ㎡) and tensile strength of 70~200N in the longitudinal direction and 10~60N in the transverse direction, it is preferable to use a pulp.

Looking at the composition ratio for each component as described above, 10-20% by weight of hemp extract, 60-70% by weight of purified water, 2-5% by weight of silver nano powder, 2-5% by weight of tabasheer, 2-5% by weight of lacquer extract It is preferable to mix in a ratio. In order to achieve the most ideal effect, it is necessary to mix 15% by weight of hemp extract, 70% by weight of purified water, 5% by weight of silver nano powder, 5% by weight of tabasheer, and 5% by weight of lacquer extract. there will be

The wet tissue using such hemp can be used by immersing a plurality of fabrics of the wet tissue in a solution to which a hemp mixture and a functional ingredient are added, and then putting it in a pouch or drying it. In particular, in the case of dried tissues, if you carry them around and use tap water or bottled water for sterilization like your hands, etc., you will immediately become a wet tissue with excellent antibacterial effect.

Hereinafter, the wet wipes using hemp of the present invention configured as described above will be looked at through examples.

Example

Prepare a mixture of 150 g of hemp extract, 700 g of purified water, 50 g of silver nano powder, 50 g of tabasheer, and 50 g of lacquer extract, and wet it with a dry tissue to prepare a wet tissue.

In addition, as a comparative example, the number of colonies was counted in the same manner as described above by using a wet tissue containing a chemical preservative such as a benzene series or a carbamate series in a disinfectant such as alcohol, and then the mortality rate was measured.

Death rate (reduction rate) = (number of control bacteria - number of samples) / number of control bacteria × 100

The results measured according to the calculation of the mortality rate are shown in Table 1 below.

division Staphylococcus aureus Pseudomonas aeruginosa coli candida albicans black mold Example 99.7% 99.6% 99.9% 97.5% 99.3% comparative example 99.9% 99.8% 93.8% 92.3% 98.3%

As shown in Table 1, it can be confirmed that the comparative example exhibits a similar killing rate to that of the example in terms of antibacterial and antifungal activity.

Therefore, as described above, even if an eco-friendly material with low toxicity to the human body is used, it can be confirmed that it has the same or excellent antibacterial properties as the wet wipes that contain existing chemical components and cause skin problems. That is, according to the present invention, it has excellent antibacterial properties and cleaning ability, provides a refreshing feeling of use by using a natural vegetable extract, and has an excellent effect of preventing side effects on the skin.
