Description

Antimicrobial Mask

The present invention is directed to antibacterial masks.

Conventional masks have been manufactured by mounting a hook means that can be worn on cotton or non-woven fabrics. These masks have a role to prevent dust or toxic gases. The masks of conventional cotton fabrics have multiple layers of fabric. Therefore, the earring straps were attached to the left and right ends of the mask body after attaching them to the main body.In case of manufacturing masks with non-woven fabrics, the non-woven fabrics are cut in the form of masks and then the left and right ends of the straps on both sides of the ear straps It has been attached and manufactured. However, typical masks have only limited effect.

In this regard, Utility Model Registration No. 20-0305562 describes masks made of activated carbon fibers. These masks are concerned with masks that prevent inhalation of fine dust or toxic gases. However, these activated carbon fibers are made of porous carbon. Although it adsorbs fine dust or toxic gas, it exhibits its effect, but after the porous carbon adsorbs such fine dust or toxic gas, its adsorption function stops, and it can not produce long time and its effect. I just show it.

Patent Publication No. 2002-0001358 describes a charcoal-containing mask. However, this mask has almost the same effect as the mask in front of it.

Although there are many dusts in the air, there are numerous pathogens such as bacteria, fungi, and viruses that directly harm human health, and when they are inhaled through breathing, they cause diseases, especially those with weak immunological effects. In-patients or people in the recovery phase may be able to cause disease by the penetration of pathogens through the respiratory tract. Furthermore, pathogens that may develop through cold- ing cold or air cannot be blocked by the usual mask.

The present inventors have completed the present invention by conducting a long study to solve the problems of these conventional masks.

The present invention relates to antibacterial masks. More specifically, it relates to antibacterial masks obtained by treating the masks with inorganic antibacterial agents.

Inorganic antimicrobial agents were developed by Catalytic Co., Ltd. in Japan. The composition is SiO ₂ , Al ₂ O ₃ , MgO, Ag, Zn, Ag, Cu, etc.SiO ₂ , Al ₂ O ₃ , MgO, Ag, Zn composition each by weight, SiO ₂ consists of about 50%, about 20 wt% Al ₂ O _3, MgO about 20% by weight, about 8%, Zn about 8% by weight of Ag, in another composition SiO ₂ 50 wt. %, Al ₂ O _{3 is} about 20% by weight, MgO is about 20% by weight, Ag is about 2% by weight and Cu is about 8% by weight. The particle size of these inorganic antimicrobials is about 2μ and the liquidity is neutral in water. The antibacterial agent has heat resistance of 500 ℃ or higher, and is insoluble in water and organic solvents, but its performance decreases in strong acid or strong alkali. The suitable range of use is pH about 5 ~ 10.

E. coli, a typical bacterium, is completely killed within 1 hour by adding 0.01% by weight in physiologically saline-free water (physiological saline or tap water) (probiotic count 0) .In the nutrient solution that E. coli is easy to multiply, it does not contain any inorganic bacteria. It proliferates vigorously, but if it is added with an inorganic antimicrobial agent, the growth stops or decreases or decreases.

In addition, bacteria other than Escherichia coli cannot be grown. The minimum growth inhibitory concentration (MIC) of this inorganic antimicrobial agent can prevent the growth of bacteria at very low concentrations.

The minimum growth inhibitory concentrations of representative microorganisms are shown in Table 1 below.

These inorganic antimicrobials also show antimicrobial activity, even with fine metals and metal oxides alone.

In the present invention, the inorganic antimicrobial agent (3) MmSiO ₃ .CaO.MnPOo obtained by melting a natural silica mineral and a phosphoric acid compound selected from CaSiO ₃ , MgSiO ₃ , Na ₂ SiO ₃ , SiO _2, or K ₂ SiO ₃ , wherein M is Alkali metal or alkaline earth metal, m is an integer of 1 or 2, n is an integer of 1 to 3, o is an integer of 3 or 4)) may be used alone or in combination with the preceding inorganic antibacterial agent. The substance also exhibits strong antibacterial activity.

Inorganic antibacterial treatment is carried out as follows.

1. Flexible and flexible resins such as ordinary acrylic resins, triacetate resins, cellophane resins, nylon resins, vinylon resins, polyurethane resins, polyester resins, polyvinyl chloride resins, epoxy resins and ethylene vinyl acetate resins. Dissolve in organic solvents, mix the suspension of the inorganic antimicrobial agents shown earlier, and prepare a suspension solution.

２．Deposit or press or squeeze onto the woven fabric made of cotton fiber, conventional mask body made of woven fabric, conventional mask body made of nonwoven fabric, non-woven fabric, ordinary mask body made of thin slice, etc. This removes the evaporation of the solvent. In this way, the inorganic antimicrobial agent is coated. Because the mask must have sufficient breathability, the organic solvent is blown with a strong wind or removed by vacuum to promote the formation of pores between the fabrics. This can improve breathability.

3. After the coating has been completed, it may be used as an antibacterial mask if it is already manufactured in the form of a mask by attaching ear straps.

4. In case of woven fabric or non-woven fabric, after forming with mask body, hang earring strap to manufacture antibacterial mask.

5. In the case of a sponge, cut the mask in accordance with the main body of the sponge, and then put the mask in the main body to manufacture the antibacterial mask.

6. The nonwoven fabric body coated with antimicrobial agent can be attached to the outer edge of the fabric by attaching a magic tape so that it can be attached and detached to a mask made of ordinary cotton fabric.

The antibacterial mask of the present invention may be manufactured as follows.

1. Synthetic fiber chips are mixed with microorganic antimicrobial agents at a ratio of about 0.01 to 10% by weight, melted and spun with fiber, then woven into fabricate a conventional mask or spun synthetic resin solution onto the fabric and spun onto fabric. You can also make antibacterial masks by making them in the form of masks and then attaching earrings or by attaching a magic tape to both sides of one side.

Next, the present invention will be described in detail as an example.

Example 9

Dissolve 10 g of cellulose acetate chips in 100 ml of acetone, filter out and remove any insoluble matters, and then suspend 5 g of inorganic antibacterial agent (1). After immersing the normal cotton fabric mask body, squeeze it out and squeeze out the excess suspension. Produce an antibacterial mask by evaporating the solvent.

Example 2

10 g of triacetate fiber chip is dissolved in 100 ml of methylene chloride, and 5 g of inorganic antibacterial agent (1) is suspended in the filtrate obtained by filtration. Here, a highly breathable foam foam sponge, which is foamed with triacetate resin, is 5 cm x 12 cm x 0.2 cm. The foamed sponge was squeezed and then compressed to remove excess suspension and evaporated to prepare a foamed sponge coated with an inorganic antibacterial agent. The sponge was coated with a layer of cotton cloth coated with an antimicrobial agent and inserted into the center of the cotton textile mask. The mask was manufactured.

Example 3

10 g of nylon 6 chips were dissolved in 100 ml of m-cresol, 10 g of inorganic antibacterial agent (1) was dissolved in 10 ml of dioxane in the filtrate, and then 5 g of inorganic antibacterial agent (1) and 2 g of inorganic antibacterial powder (3) were suspended. The nonwoven fabric obtained by molding with a nonwoven fabric was deposited here, and then pressed and removed, and then the excess suspension was removed.The mask was then restored to its original shape, and the solvent was evaporated while vigorously blowing to produce an antibacterial mask.

Example 4

10 g of polyvinyl alcohol is dissolved in 100 ml of water. After 5 g of inorganic antimicrobial agent (1) is suspended in this solution, the gauze fabric woven with cotton fibers is deposited and then compressed to add the extra suspension and then spread. Treatment with formalin under heating causes chemical reactions. This formalization causes the following chemical reactions to convert polyvinyl alcohol to vinylon fibers and form a very thin vinylon fibrous membrane that contains inorganic antibacterial agents.

The resulting antimicrobial mask was fabricated using the fabric thus obtained.

Example 5

10 g of ethylene vinyl acetate copolymer (EVA) is dissolved in 10 ml of methyl ethyl ketone, and then suspended in 10 g of inorganic antibacterial agent (2). The non-woven fabric is immersed in this suspension, and then compressed to remove the excess suspension and then the non-woven fabric is returned to the original shape. After blowing, strongly evaporate the solvent and evaporate the solvent to obtain a non-woven fabric with a film of inorganic antimicrobial agent. The antimicrobial mask was prepared by molding or cutting the antimicrobial nonwoven fabric into the mask body and then attaching earrings.

Example 6

10 g of polyvinyl chloride is dissolved in 500 ml of a 1: 1 mixture of acetone and benzene, filtered, and then suspended in a filtrate, and then suspended in a suspension of 10 g of an inorganic antibacterial agent (1) and an inorganic antibacterial agent (2). After weaving cotton fabric with gauze fabric, the fabric is deposited and then compressed to remove the excess suspension, then spun into the form of the original fabric, and then blasted with strong blowing to obtain a cotton fabric coated with inorganic antibacterial agents. The antimicrobial mask fabric was manufactured by using the antibacterial cotton fabric, or by overlapping the antibacterial cotton fabric and the normal cotton fabric alternately, the mask body was fabricated, and then the earrings were attached to both ends to produce the antimicrobial mask.

Example 7

Using the same method as in the above embodiment, using polyester, cellophane, polyethylene terephthalate, polyacryl, etc. as a binder, applying an inorganic antimicrobial to a mask fabric or nonwoven fabric, and then applying the inorganic antimicrobial coated material. Thus, the mask body can be manufactured and anti-bacterial mask can be manufactured by placing earrings on both ends.

This antimicrobial mask is highly antibacterial and can prevent bacterial infections through airways. It is not resistant to bacteria and viruses, and it can be washed and used several times to reduce its antimicrobial effect. It is suitable for doctors and nurses who work in hospitals that treat patients who have several diseases, including their own low immunity.They are also needed for infectious diseases when they are infected with seasons or air. It is a mask.

The antibacterial mask of the present invention may be manufactured as follows.

Synthetic fiber, acrylic fiber, acetate fiber, nylon, nilidene fiber, vinylon fiber, polyurethane fiber, polyester fiber, polyethylene fiber, polyvinyl chloride fiber, and polypropylene fiber are melted and degassed. The method of manufacturing synthetic fibers by degassing, spinning, stretching and then manufacturing the spinning solution after it has been carried out for several decades has been known for the public knowledge.

When the antimicrobial mask of the present invention melts a chip of such synthetic fiber, it is melted by adding 0.001 to 5% by weight to the weight of the chip, and then degassing, spinning and stretching to manufacture the antimicrobial synthetic fiber. Fabrics can be manufactured or fabricated from non-woven fabrics with non-woven adhesives, and then fabricated into nonwoven fabrics. After the fabrics have been fabricated with fabrics or non-woven fabrics, the earrings can also be attached to ear masks. The antimicrobial masks produced in this way may have some parts of the inorganic antimicrobial agent inside the fiber, and in this case, the antimicrobial power may not be able to represent the antimicrobial power, and thus the antimicrobial power is slightly lowered.

Example

100 g of nylon 6 chips were added to 10 g of inorganic antimicrobial agent, and then melted. After degassing, spinning and stretching were performed to produce antibacterial nylon. In this way, the antibacterial nylon yarn was woven, or short fibers were used to manufacture the mask. The antimicrobial fabric thus prepared was cut in the form of a mask and then sewn as needed, and ear hooks were attached to both ends to produce an antimicrobial mask.

Example

After adding 5 g of inorganic antibacterial agent (1) to 100 g of polypropylene chip, it is melted. After degassing, it is spun and then stretched to produce an antibacterial polypropylene yarn. The antibacterial polypropylene yarn thus produced is woven or short fibers. After fabricating the nonwoven fabric, the fabric of the mask was fabricated. The fabric of the antibacterial fabric thus prepared was cut into the shape of the mask, and then sewn as needed and the ear hooks were attached to both ends to produce the antibacterial mask.

Example 90

100 g of polyvinyl alcohol was dissolved in a large amount of water that could be dissolved, and then 5 g of inorganic antibacterial agent (2) was added thereto. After degassing, the heated formalin solution was heated, and the prepared solution was spun onto the solution. In this way, the same chemical reaction as in Example 4 occurs, and yarns containing inorganic antimicrobial agents in the fibers and on the fiber surface are treated. The yarns are treated in the same manner as in Example to obtain an antibacterial vinylon fabric or a nonwoven fabric. Molded fabrics or non-woven fabrics are used as the mask body, attached with earrings, or attached with a magic tape at the end of the fabric.

The antimicrobial mask of the present invention is not only effective in blocking the dust and pollutants in the air, but also contributes to the public health by blocking the infection of various microorganisms, bacteria, fungi or viruses in the air.
