The present invention relates to a sanitary mask to which an antibacterial and deodorant composition is applied.

More specifically, in a safe and effective amount of β-acetylpropionic acid and Ag metal salts and cellulose, polyvinyl alcohol, polyvinylpi, which are hydrophilic polymers having hydroxyl groups as binders for attaching them to fiber structures of various materials and forms. By using a fiber structure manufactured using one or more compounds composed of rolidone, etc., various types of antimicrobial and deodorant compositions are applied to produce a sanitary mask to exhibit continuous antimicrobial and antiviral and deodorizing effects even after long-term use. .

Conventional masks have been produced by attaching earring means that can be worn on cotton, nonwoven fabrics, and the like. These masks serve to partially block dust and toxic gases.

On the other hand, Utility Model Registration No. 20-0305562 describes a mask formed of activated carbon fibers. The mask made of activated carbon fibers has a function of adsorbing fine dust or toxic gas, while porous carbon After adsorption of such fine dust or toxic gas, its adsorption performance is weakened and the long-term effect cannot be obtained, and the effect expected only in a short time can be obtained.

In addition, Utility Model Registration No. 20-0282997 discloses a mask in which a hepa filter, which is an antibacterial filter, is incorporated in the mask to block dust and bacteria from entering the respirator. However, such masks cause inconvenience to the mask wearer's breathing by using a hepa filter and are very likely to cause an unpleasant odor in the oral cavity.

Recently, development of a sanitary mask treated with an antimicrobial agent is underway, and antimicrobial agents known to date are very numerous, as shown in Table 1 below.

As can be seen in Table 1, the antimicrobial agent contains most of the cation, which disrupts or destroys the cell membrane of the anionic bacteria, or diffuses into the cell, causing metabolism to kill the bacteria.

On the other hand, antibacterial agents are largely classified into a release type and a fixed type.

Among them, the release type antimicrobial agent refers to an antimicrobial agent having a mechanism of slowly releasing the antimicrobial agent and killing the surrounding bacteria, and includes inorganic, organometallic, amide, amphoteric, and guanidine-based compounds. Fixed antimicrobial agents are sometimes called non-release or defensive types, which have a mechanism of killing when bacteria come into contact with the antimicrobial agent while the antimicrobial agent is fixed by adsorption or chemical bonding to the substrate. Representative examples thereof include organosilicon quaternary ammonium-based antibacterial agents.

The release type antimicrobial treatment agent has a disadvantage in that the antimicrobial activity is gradually decreased since the release concentration gradually decreases due to the continuous release of the antimicrobial treatment agent, while the organic silicone quaternary ammonium salt, which is a fixed antimicrobial treatment agent, is resistant and harmful to organic antibiotics. This medical problem can be a problem, so it is not suitable for oral masks.

The present invention has been made in view of the above problems,

Polyvinyl alcohol and polyvinylpyrrolidone, which are hydrophilic polymers having a hydroxyl group harmless to the human body, as a binder for attaching to a safe and effective amount of β-acetylpropionic acid and Ag metal salts or antimicrobial composite metal salts and fiber structures of various materials and forms After preparing antibacterial and deodorizing composition composed of distilled water and the like, the fiber structure is immersed to allow sufficient absorption, and then, the solution is placed in a high speed dehydrator which is dehydrated by centrifugal force to remove excess solution. By drying to form a uniform and firm antibacterial and deodorizing film, by using it to complete the hygienic mask harmless to the human body,

Its purpose is to enable immediate and continuous antibacterial, antiviral and deodorant function so that it can make a significant contribution to public health.

The present invention for achieving the above object is beta -acetylpropionic acid, Ag metal salt or antimicrobial composite metal salt, polyvinyl alcohol and polyvinyl alcohol having a hydroxyl group harmless to the human body as shown in Figures 1a and 1b The antibacterial and deodorizing composition prepared by properly mixing vinylpyrrolidone and distilled water is prepared.

The antimicrobial and deodorizing composition was immersed in various forms of fiber structure 10 made of cotton, rayon, acetate, polyamide, polyester, and the like, and centrifugal force was applied so that the wet pick-up was about 20-50%. After removing the excess solution in a dehydrating high-speed dehydrator, and put the coating object in a hot air dryer and dried to sew the fiber structure (10) coated with the antibacterial, deodorant composition to the inner surface of the mask or directly to the coated fiber structure Harmless to the human body in a variety of ways, such as to attach a uniform and robust antibacterial, deodorant composition 110 is to manufacture a sanitary mask 100 is applied.

In order to achieve the above object, the present invention is designed to achieve a safe and effective amount of β-acetylpropionic acid, a metal salt, and a fiber structure (mask).
