When provided, a stable flow of air can be provided, but there may be a problem in that foreign harmful substances such as viruses or bacteria pass through the empty space.

Accordingly, the virus-inactivating laminated fabric 200 disclosed in this specification is prepared to be overlapped with each other and in the first fabric 110a and the second fabric 110b facing each other among a plurality of fabrics 110a and 110b having air permeability. , A technique in which at least some of the plurality of salt islands 120a of the first fabric 110a face each other with a space between the plurality of salt islands 120a of the second fabric 110b. Through this, even if foreign harmful substances such as viruses or bacteria pass through the empty space between the plurality of salt islands 120a of the second fabric 110b, at least one of the plurality of salt islands 120a of the first fabric 110a Some may disable it. That is, the virus-inactivating laminated fabric 200 disclosed in this specification not only provides a stable flow of air, but also presents a technology capable of effectively blocking foreign harmful substances such as viruses and bacteria.

Figure 9 (a) is a view showing the results of the staphylococcus aureus antibacterial test of samples taken from the initial surface of the fabric prepared in the form of islands of silver (Ag) and salt (NaCl) in FIG. It is a diagram showing the results of the staphylococcus aureus antibacterial test of the sample taken from the surface after 18 hours of passage of the fabric prepared in the form of an island with silver (Ag) and salt (NaCl). As shown in FIGS. 8 and 9, after depositing silver (Ag) and salt (NaCl) into a plurality of islands through a sputtering method on the fabric 110, an antibacterial test was performed. The technique disclosed herein It can be seen that it exhibits excellent antibacterial properties.

In summary, the technology disclosed herein is a technology capable of providing a salt layer 120 capable of inactivating foreign harmful substances such as viruses or bacteria on the fabric 110 or the laminated fabric 110a, 110b by a physical vapor deposition method. provides Through this, the technology disclosed herein is harmful to the respiratory tract such as the user's mouth and nose when the fabric 110 or laminated fabrics 110a and 110b provided with the salt layer 120 are used in the manufacture of hygiene products such as masks. In addition to preventing the inflow of substances, it can provide an effect that can solve the problem that harmful foreign substances on the outer skin of the sanitary product can spread to the surroundings through the user's body, such as the user's hands.

In addition, the technology disclosed in this specification makes the salt layer 120 or the salt island 120a contact the metal layer 130 or the metal island 130a provided on the fabric 110 so that the salt layer 120 or the salt island 120a ) can provide an effect that is well adhered to the fabric 110.

In addition, the technology disclosed in this specification makes the salt layer 120 or the salt island 120a contact the carbon layer 140 provided on the fabric 110, so that the salt layer 120 or the salt island 120a is connected to the fabric 110 ) can provide an effect that makes it adhere well to.

In addition, the technology disclosed herein provides at least one selected from a metal layer 130, a salt layer 120, a carbon layer 140, and combinations thereof on the fabric 110 through a sputtering method as an example of a physical vapor deposition method. By doing so, it is possible to provide an effect of increasing the adhesion to the metal layer 130, the salt layer 120, the carbon layer 140, and at least one selected from a combination thereof to the fabric 110.

In addition, the technology disclosed herein can increase the inactivation of viruses or bacteria by providing the fabric 110 with at least one selected from the metal layer 130, the carbon layer 140, and combinations thereof in addition to the dye layer 120. effect can be provided.

In the drawing, the salt layer 120, the metal layer 130, and the carbon layer 140 provided once on the fabric 110 or the laminated fabrics 110a and 110b are illustrated, but the salt layer 120, the metal layer 130, and the carbon layer 120 It will be apparent that the layer 140 may be continuously or intermittently provided on the fabric 110 or the laminated fabrics 110a and 110b at least once.

From the foregoing, it will be understood that various embodiments of the present disclosure have been described for illustrative purposes, and that there are various modifications possible without departing from the scope and spirit of the present disclosure. And the various embodiments being disclosed are not intended to limit the disclosed spirit, and the true spirit and scope will be presented from the following claims.
