The configuration of the mask capable of face recognition according to the present invention described above will be described in more detail.

As shown in Figure 3, it includes a mask body 110 for covering the nose and mouth and earrings 120 for hanging on the ears.

In particular, the mask body 110 has a filtering layer 111 formed in the center and an outer antibacterial layer 112 formed in an outward direction, between which the filtering layer 111 and the outer antibacterial layer 112 are bonded. and an outer adhesive layer 113 formed thereon.

The mask body 100 further includes a printed layer 114 formed as an outer surface of the outer antibacterial layer 112 .

On the other hand, the mask body 110 has an inner antibacterial layer 112' formed in an inward direction from the central filtering layer 111, and therebetween to bond the filtering layer 111 and the inner antibacterial layer 112'. It includes an inner adhesive layer 113' formed on, and further includes an embossing layer 115 formed as an inner surface of the inner antibacterial layer 112'.

First, the filtration layer 111 may be configured to filter foreign substances included in external air introduced through the mask body 110 and may be made of a polyurethane material.

More specifically, the filtration layer 111 may be nanofibers formed by electrospinning a polyurethane solution. For example, the filtration layer 111 of polyurethane nanofibers may be formed by electrospinning a polyurethane solution on a fiber base (not shown) using an electric spinning machine. Therefore, it is possible to increase the filtration efficiency of fine foreign substances through the filtration layer 111 of nanofibers. When using such a fiber base (not shown), the filtration layer 111 may include a fiber base and polyurethane nanofibers.

Here, the electric spinning machine is a well-known technique, although not shown, a spinning solution main tank filled with a polymer spinning solution therein, a metering pump for supplying the polymer spinning solution filled in the spinning solution main tank in a quantitative amount, and spinning A nozzle block in which a plurality of pin-shaped nozzles are arranged to discharge the polymer spinning solution filled in the solution main tank, a collector spaced apart from the nozzle at a predetermined interval to accumulate the polymer spinning solution sprayed from the nozzle, and a collector It may include a voltage generator that generates a voltage.

Therefore, the polymer spinning solution filled in the spinning solution main tank is continuously and quantitatively supplied into a plurality of nozzles formed on the nozzle block through a metering pump, and the polymer spinning solution supplied is spun through the nozzle onto the collector at high voltage. And while nanofibers are formed on the fiber base that is focused and moved on the collector, the filtration layer 111 can be formed.

On the other hand, as another embodiment, although not shown, when the above-mentioned polymer spinning solution is filled with the copper ion aqueous solution to be described later in the spinning solution main tank, a nanofiber filtration layer is formed on the fiber base and the nanoparticles Since copper ions can be positioned between the , it is possible to add an antibacterial function to one filtering layer without separately stacking the antibacterial layer.

The outer antibacterial layer 112 and the inner antibacterial layer 112′ are configured to suppress the colonization of infectious agents such as viruses or bacteria on the mask body 110.

Therefore, when an infectious agent such as a virus or bacteria gets on the mask 100, the antibacterial layer 112 makes it difficult for the infectious agent to inhabit, thereby suppressing the remaining or spreading of the infectious agent. For example, when the user touches the outer surface of the mask 100 with his hand while wearing the mask 100 of the present invention, it is possible to prevent the transfer of the infectious agent to the user's hand, and furthermore, the infectious agent in the user's hand. Even if it is transferred to the mask 100, the growth of the infectious agent in the mask 100 can be suppressed.

The outer antibacterial layer 112 and the inner antibacterial layer 112′ may be formed by immersing cellulose fibers in an aqueous solution of copper ions. Therefore, it is cheaper than silver, which is a representative antibacterial material, and thus the unit price of the product can be lowered, and antibacterial properties similar to those of silver can be provided, and when the mask 100 of the present invention is worn, the facial skin can be improved. For example, copper ions play an important role in many physiological processes in the human body and can be used to form copper-dependent enzymes, such as cytochrome c oxidase required for energy production and superoxide scavenging enzyme involved in antioxidants. In addition, copper ions may be essential for enzymes such as lysole oxidase, which is required for cross-linking of elastin and collagen, and dopamine beta hydroxylase, which is required for catecholamine formation.

The copper ion aqueous solution may be prepared by dissolving copper chloride (CuCl2.2H2O) in ultrapure water (De-Ionized Water). In addition, immersion may be performed at approximately 40 to 80 degrees (° C.) for approximately 30 minutes.

As described in the thesis "Man-Made Fiber Year Book 2012; Chung Chun-hee", cellulose fiber having a staple length of 60 mm and 33 dtex was provided and used. In order to absorb copper ions into cellulose fibers, 10.732 g of CuCl ₂ .2H ₂ O was dissolved in 1 L of ultrapure water to prepare a 4 g/L copper ion aqueous solution.

25 mL of the solution was diluted in 1 L of ultrapure water to prepare a 100 mg/L copper ion aqueous solution. In order to confirm the copper ion absorption characteristics according to the treatment time, 10 g of cellulose fiber was immersed in 1 L of an aqueous solution containing 100 mg/L of copper ion, and after 0.5, 1, 3, 8, and 24 hours, 10 mL of the solution was collected. After diluting in 100 mL of ultrapure water, the concentration of copper ions was analyzed using an atomic absorption spectrometer.

As a result of the analysis, the amount of copper ions absorbed into the cellulose fiber was 6.64 mg/g when treated for 30 minutes, but increased to 6.86 mg/g when treated for 24 hours.

When the treatment time was 30 minutes, the copper ion absorption amount reached equilibrium with 96.8% of the copper ion absorption amount when the treatment was performed for 24 hours. Judging from these results, it was found that the copper ion absorption of the cellulose fiber was relatively very fast and reached equilibrium within 30 minutes.

In order to confirm the effect of the treatment temperature on the copper ion absorption characteristics, a solution containing 80 mL of copper ions was prepared by diluting 5 mL of an aqueous solution having a copper ion concentration of 4 g/L with 250 mL of ultrapure water. After treating 2 g of cellulose fibers at 40, 50, 60, 70, and 80 ° C. for 1 hour, the remaining solution after removing the cellulose fibers was analyzed using an atomic absorption spectrometer. As the treatment temperature increased, the amount of copper ion absorption increased. The amount of copper ions absorbed at 80℃ was 13.1% more than the amount of copper ions absorbed at 40℃.

In order to confirm the copper ion absorption characteristics according to the concentration, 5, 10, 25, 50, and 100 mL of an aqueous solution having a copper ion concentration of 4 g/L were diluted with 1000 mL of ultrapure water, respectively, to prepare five treatment solutions having different copper ion concentrations. 10 g of cellulose fiber was added and treated at room temperature for 24 hours. The treated fibers were washed with ultrapure water and then dried at 105°C.

In order to analyze the copper ion content in the cellulose fiber, about 1 g of the cellulose fiber was dried at 105° C. for 4 hours to obtain a constant weight (W). The fiber was placed in a 100 mL beaker and 20 mL of a 98% sulfuric acid aqueous solution was added. After 24 hours, it was diluted with 1L of ultrapure water and analyzed using an atomic absorption spectrometer. When the copper ion concentration was 20, 40, 100, 200, and 400 mg/L, the copper ion absorption amount was 1.16, 1.23, 6.53, 8.03, and 9.22 mg/g, respectively, and the absorption amount also increased as the copper ion concentration increased. The amounts of copper ions absorbed by the cellulose fibers were 58.0, 30.8, 65.3, 40.2, and 23.0% of the copper ions contained in each treatment solution.

Through the above results, it was confirmed that fibers containing different amounts of copper ions could be manufactured by varying the concentration of copper ions in the treatment solution.

The outer adhesive layer 113 and the inner adhesive layer 113' may be formed by electrospinning a solution of low melting point polyurethane or low melting point polyester.

Therefore, pores in the form of nanofibers can be formed in the outer adhesive layer 113 and the inner adhesive layer 113′ through electrospinning, so that external air flows in when inhaling through the mask 100 of the present invention. While the breath is discharged to the outside during exhalation or through the adhesive layer 113, the flow can be made smoothly along with filtering.

The outer adhesive layer 113 and the inner adhesive layer 113` are formed on either one of the filter layer 111 and the antibacterial layer 112 first to overlap the filter layer 111 and the antibacterial layer 112. can be glued.

As described above, in the mask capable of facial recognition according to the present invention, the outer antibacterial layer 112 is formed in the outer direction around the filtering layer 111, and the inner antibacterial layer 112' is formed in the inner direction, respectively. Dara can suppress not only external infection sources, but also both internal infection sources, which are droplets emitted from the mouth of a person wearing a mask.

The printed layer 114 is a layer created by photographing a mask wearer's face in advance and printing it on the outer antibacterial layer 112 as much as the portion covered by the mask.

The embossing layer 115 is formed on the inner surface of the face-recognizable mask according to the present invention to minimize the contact area with the user's skin, minimize skin trouble due to contact, and improve wearing comfort.

On the other hand, the earring 120 is formed in the mask body 110 by being fastened to the earring fastening part 116 formed by a pair on both sides of the mask body 110, as shown in FIG. 4A.

The earring fastening part 116 has a hollow inside so that the upper fastening ring 122 and the lower fastening ring 123 of the earring 120 described later are inserted and coupled in a configuration in which the top and bottom pass through.

In particular, the earring 120 includes a band 121, an upper fastening ring 122, a lower fastening ring 123, and a length adjustment unit 124, as shown in FIG. 4B.
