In modern life, masks have become a necessity in daily life. Masks are widely used to prevent foreign substances such as dust or yellow dust in the air, as well as bacteria or viruses from entering the respiratory tract by covering the nose and mouth. In general, a mask has a mask body made of a cotton fabric or a non-woven fabric, and a fixing member (ring strap) coupled to both sides of the mask body and for hanging over the ear.

Meanwhile, along with SARS (Severe Acute Respiratory Syndrome) or avian influenza, the world is experiencing viral infections with acute respiratory coronavirus 2 (SARS-CoV-2), a deadly viral respiratory disease that emerged in Wuhan, China around December 2019. We are facing the crisis of a spreading pandemic, and urgent measures are needed.

It is reported that the coronavirus and the like are mainly transmitted through human-to-human contact through respiratory droplets generated by coughing and sneezing, or through surfaces of objects contaminated by people who cough or sneeze. Therefore, in order to prevent infection by these viruses, wearing of various masks such as a one-time medical mask, a 3D mask, a cotton mask, etc. has become commonplace.

However, since wearing a mask for a long time, personal mask hygiene management is difficult. In particular, for people with respiratory diseases such as rhinitis and sore throat, wearing a mask can make various diseases worse.

In order to solve this problem, various antibacterial masks have been developed in recent years. For example, Korean Patent No. 10-2144869 has developed a mask incorporating various functional elements such as antibacterial, deodorizing, negative ion and far-infrared emission. However, such a mask not only consumes a lot of time and money in the manufacturing process, but also can cause skin trouble or harm the human body if it is manufactured incorrectly as it directly touches the skin.

Specifically, the main body is prepared by stirring after adding liquid germanium, silver, sodium hypochlorite, titanium oxide and penetrant to distilled water at 75 to 85 ° C. After the mask fabric is immersed in the cooled antibacterial composition, the fabric loaded with the active ingredient is passed through a compression roller to dehydrate, and then dried at 75~85℃ and cutting and processing the dried fabric. can be manufactured. Let's take a closer look below.

First, an antibacterial composition for supporting a functional active ingredient on a fabric is prepared first. The antibacterial composition is distilled water 3-7 parts by weight of germanium, 0.1-1 parts by weight of silver, 0.001-0.01 parts by weight of sodium hypochlorite, 1-5 parts by weight of titanium oxide and 0.1-0.5 parts by weight of a penetrant to 90-95 parts by weight of distilled water After stirring, it can be prepared.

The liquid germanium is for improving immunity by emitting far-infrared rays from a place close to the skin in addition to sterilization and virus removal functions, and the content thereof is preferably 3 to 7 parts by weight. If it is smaller than this, it may be difficult to sufficiently exhibit the functional effect of germanium, and if it is large, overall miscibility may be deteriorated.

The silver has antibacterial, deodorizing, anion and far-infrared emitting effects, and it is common to use nano-sized silver of high purity. The silver content is preferably 0.1 to 1 part by weight. If the amount is smaller than this, it may be difficult to sufficiently exhibit the functional effect of silver, and if it is larger, overall miscibility may be deteriorated.

On the other hand, there is a problem in that a surfactant or various additives must be used to suppress aggregation of the silver particles when the silver nanoparticles are prepared. It is difficult to sufficiently exhibit the functional effects of silver, or it may have a unique color, and harmful effects may occur due to additives.

Accordingly, as a preferred embodiment, the present invention uses a complex prepared by reacting a salt containing a silver ion with a salt containing a sulfate-based anion, thereby exhibiting antibacterial activity, colorless, transparent, and stable even under ultraviolet light. can do.

In this case, the salt containing the silver ion and the sulfate-based anion may be various materials capable of forming a complex, but preferably, the salt containing the silver ion may be silver nitrate or silver acetate, and the sulfate-based anion The salt containing may be any one selected from sodium sulfate, sodium sulfite, potassium sulfate, potassium sulfite, ammonium sulfate, and ammonium sulfite or a mixture thereof.

When the silver ion is used in the form of a silver-sulfate complex, the content of the silver-sulfate complex is preferably 0.1 to 2 parts by weight.

The sodium hypochlorite has a sterilizing function to remove fungi or mold, and the content thereof is preferably 0.001 to 0.01 parts by weight. If it is smaller than this, it may be difficult to sufficiently exhibit the functional effect of sodium hypochlorite, and if it is large, toxicity may occur.

The titanium oxide is effective in sterilization, odor removal, antibacterial and the like because its oxidation function is activated when it receives ultraviolet rays or sunlight. The content of the titanium oxide is preferably 1 to 5 parts by weight, if it is less than this, it may be difficult to sufficiently exhibit the functional effect of the titanium oxide, and if it is large, overall miscibility and physical properties may be deteriorated.

The penetrating agent serves to help the active ingredients penetrate well into the fabric, and various surface active ingredients commercially applicable to fibers may be used. The content of the penetrant is preferably 0.1 to 0.5 parts by weight, and if it is less than this, it may be difficult to sufficiently exhibit the functional effect of the penetrant, and if it is large, overall miscibility and physical properties may be deteriorated.

The antibacterial composition prepared as described above is cooled to 25-30° C., and the mask fabric is put into the cooled antibacterial composition and immersed for about 30 minutes to 3 hours. In this process, the active ingredient is loaded on the mask fabric. The mask fabric loaded with active ingredients is passed through a compression roller, first subjected to a dehydration process, and then dried by heating at 75~85℃.

The mask that has undergone the dehydration and drying process as described above may be manufactured as a mask through the cutting and processing process as it is. A step of drying after treatment may be further performed.

The herbal distillate is a step of supporting 10 to 20 g of upper leaf, 10 to 20 g of pine leaf, 5 to 10 g of cheongung, 10 to 20 g of jujube and 5 to 10 g of Angelica per 1 L of purified water for 24 to 48 hours. It can be prepared through the steps of extracting the active ingredient by heating at ~130 ° C. for 2-3 hours and diluting by adding 2-4 L of purified water per 1 L of the extract from which the active ingredient is extracted, and then heating in a distiller to obtain a distillate. .

The upper leaf is a medicinal herb dried the leaves of a mulberry tree in the Morus family or a related plant of the family Morus, and the pine needle is a leaf of a pine plant of the Pine family, and both the upper leaf and the pine needle have an effect of soothing the skin.

The cheongung is a perennial plant of the dicotyledonous plant Dicotyledonous family umbel, and the jujube refers to the ripe fruit of a jujube tree or a Boeun jujube tree, and the Angelica oleifera refers to the dried root of the umbel and the Chinese Angelica. All of the above medicines have the effect of giving nutrition to the skin and adding shine.

It is preferable that 10-20 g of upper leaf, 10-20 g of pine leaf, 5-10 g of cheongung, 10-20 g of jujube, and 5-10 g of angelicae are used as the oriental medicinal ingredients per 1 L of purified water, and when their content is less than this, each functional effect is obtained. It is difficult to fully demonstrate it, and in the case of more than this, the functional synergistic effect is insignificant compared to the cost increase.

The herbal ingredients are preferably subjected to a step of soaking in purified water for 24 to 48 hours before starting the full-scale extraction process. While the oriental herbal ingredients are subjected to the loading process, moisture can sufficiently penetrate inside the materials, and the active ingredients can be more efficiently eluted in the subsequent heat extraction process.

After the supporting process, the supporting solution is heated at 100~130℃ for 2~3 hours to extract the active ingredient. After that, the extract from which the active ingredient is extracted is not used as it is, but is subjected to a separate distillation process in order to collect small molecular size components that are less irritating to the skin and easily absorbed.

Specifically, it is preferable to prepare through the step of obtaining a distillate by adding 2 to 4 L of purified water per 1 L of the extract from which the active ingredient is extracted, followed by dilution by heating in a distiller. In detail, after heating the distiller to 350~450℃ first, when the distillate starts to fall from the heated distiller drop by drop, lower the temperature to 250℃ and continue the distillation process for 8~12 hours, finally distilling 2~4L liquid can be obtained.

The oriental distillate prepared in this way can be sprayed on the surface of the mask fabric, dried, and finally used as a mask fabric. The amount of spraying is enough to evenly coat the active ingredient on the surface of the fabric.

After the mask fabric manufactured in this way is cut to an appropriate size, it is sewn to have a plurality of transverse overlap processing parts. Thereafter, a string for fixing that is wound around the wearer's ears is provided at both side ends of the body, and a nose piece wire is formed at the top of the body to finally be supplied to the market.
