Description

Gift mesh and antibiotic mask using the same {Mesh of Ag Wire and Antibiotic Mask Using the Same}

The present invention is made of a silver metal yarn (hereinafter referred to as a silver yarn) or silver twisted yarn, and the mesh or knitted fabric is inserted between the skin and the inner skin of the mask or introduced into the air by using at least one of the outer skin or the inner skin The present invention relates to a silver mesh having an antibacterial function for preventing the invasion of bacteria and an antimicrobial mask using the same.

Masks are generally hygienic household goods that can cover the nose and mouth to prevent cold or inhalation of dust (dust) in the air.

However, in the air, in addition to these dusts, there are many pathogens such as bacteria, fungi, and viruses that directly harm the human body, and when inhaled into the human body through breathing, the disease may be caused, especially the elderly, children, and the sick with weak immunity. In-patients are very likely to cause disease due to the penetration of these pathogens. Moreover, pathogens that can develop through a flu or air cannot be prevented with a normal mask.

Antibacterial masks or antibacterial masks using antimicrobial fabrics or the like have also been used. By the way, a separate antibacterial mask has a bad smell and may cause side effects on the skin if worn for a long time, and the antimicrobial persistence by washing is poor.

In addition, if a conventional mask is worn for a long time, the mask is contaminated by the germs of its mouth, and the smell of the mouth is not deodorized, so it must be replaced frequently with a new mask, that is, a problem that there is no deodorizing function or weakness. I also have

The mask is largely composed of a mask body covering the wearer's nose and mouth and a pair of earring straps, which are wearing bands, and have been manufactured by attaching earring straps, which are hook means, to hang on the mask body such as cotton or nonwoven fabric. For example, a conventional cotton fabric mask has been manufactured by attaching earrings to the left and right ends of the mask body with several layers of fabrics in layers, and in the case of a mask made of a nonwoven fabric, one or more layers of nonwoven fabrics are used. It was prepared by cutting in the form of a mask and then attaching earrings to the left and right ends thereof.

Patent Document 10-2004-0106959 (copper fiber sterilization mask) is an anion that uses at least one or more strands of ultrafine microfibers between the inner and outer skins of a mask using a copper microfiber thinned an oxygen-free copper wire to a diameter of 30 μm through a fresh machine. It is composed by inserting a verbal knitted fabric which is woven together with the fibers in a vertical and horizontal lattice form.

The verbs are blended together with regular fibers and blended, and the antimicrobial verb knitted fabrics are twisted with two or three strands of microfine verbs with one or two general fibers.

In this case, although the antimicrobial property, which is inherent in copper, may be exhibited to some extent, the surface of the copper antimicrobial activity may not be coated with any material.

However, in this case, discoloration occurs due to copper oxidation, and the surface-oxidized verbs are greatly degraded in antimicrobial activity. Therefore, in order to exhibit sufficient antimicrobial activity, a large amount of copper wire should be used, resulting in heavy weight. In general, depending on the environment, copper antibacterial activity is not possible in about 1/20 ~ 1/50 of silver.

Patent No. 10-0717884 (Antibacterial mask) absorbs the antimicrobial material extracted from olive, cinnamon, ginger, pine, dysentery, spearmint, coniferous oil, tansy, serbia, herb to sepiolite, and adheres the sepiolite between cotton fibers. Proposed antibacterial mask.

In this case, the antimicrobial properties are insufficient, and there is a problem such as deterioration of the antimicrobial persistence due to washing.

On the other hand, silver is known to have excellent sterilization and deodorization effects, excellent electromagnetic and water wave blocking effects, excellent radiation effects of far infrared rays including anions, and antibacterial and antifungal effects. In addition to the body, silver is an essential metal to enhance immunity.

An antibacterial mask using silver having such antibacterial function has also been developed.

Registered Room 20-0407942 (Antibacterial mask) discloses an antimicrobial mask using an antimicrobial nonwoven fabric composed of silver, the inner skin, outer skin or filter part of a mask, and is a bonding method in which the yarn is floated on the nonwoven fabric using a stitch bonding method.

In this case, no matter how good the antimicrobial activity of silver, but the surface area that can show the antimicrobial activity is weak, and the antimicrobial power is weak, as the stitching method is used, the work process is also complicated and the process costs a lot.

Therefore, the object of the present invention is to have a continuous antimicrobial sterilization function after washing, to protect the human body from pathogenic bacteria in the air, to deodorize the contamination caused by the smell of the mouth that occurs when worn, and to prevent other people's respiratory diseases The present invention provides a silver mesh and an antimicrobial mask using the same to prevent infection.

In addition, another object of the present invention by using a fine fine silver (Ag fine wire) manufactured to a uniform diameter of 0.05mm or less by the metal processing technology as a yarn, the surface is thin and smooth, showing excellent fit (flexibility) as a fiber The present invention provides an excellent antimicrobial silver mesh and an antimicrobial mask using the same.

According to an aspect of the present invention for achieving the above object, after casting a silver alloy containing pure silver or copper into a wire rod by using a directional solidification method, the cast wire is 0.015 to 0.05mm in diameter by a drawing process Manufactured by using at least one of a warp yarn and a weft yarn using at least one of a silver yarn composed of at least one strand molded from a microfiber yarn and a silver-bonded yarn obtained by covering or splicing the fiber yarn made of natural fibers or synthetic fibers to the silver yarn It provides a gift mesh characterized in that.

The number of the silver mesh is 50 to 400 mesh, the silver mesh is a warp or weft yarn is inserted between the yarn or silver twisted yarn fiber yarn made of natural fibers or synthetic fibers, the spacing between the silver yarn or silver twisted yarn is from 0.02mm to It is characterized in that 10mm.

According to another aspect according to the present invention, the inner wire and the shell, and inserted between the endothelial and the outer shell, the silver wire containing pure silver or copper after casting by wire using a directional solidification method cast the cast wire in the drawing process At least one of the silver yarn composed of at least one strand formed of a microfiber having a diameter of 0.015 to 0.05 mm, and the silver twisted yarn obtained by covering and splicing the fiber yarn made of natural fibers or synthetic fibers to the silver yarn, It provides an antimicrobial mask, characterized in that it comprises a silver mesh filter layer prepared using at least one.

At least one of the endothelial and the outer skin is made of a silver mesh produced using a silver yarn or silver twisted yarn, and at least one of the endothelial and the outer skin is made of a knitted fabric made using a silver yarn or a silver twisted yarn.

In addition, the silver mesh or knitted fabric may further include a fiber yarn made of natural or synthetic fibers between the silver yarn or silver twisted yarn used as warp and weft yarn.

According to another aspect of the present invention, in the antimicrobial mask having an antimicrobial filter layer inserted between the endothelium and the outer skin, the endothelial, outer skin and antimicrobial filter layers each contain a silver mesh or silver twisted yarn knitted fabric containing a diameter of 0.015 to 0.05 mm. It provides an antimicrobial mask, characterized in that consisting of.

Therefore, by manufacturing an antimicrobial mask using a silver mesh or a silver yarn made of a silver yarn or silver twisted yarn according to the present invention or a knitted fabric containing a silver yarn or silver twisted yarn, to prevent the intrusion of bacteria that can be inhaled from the air during breathing, As it deodorizes the contamination caused by the smell of the mouth generated when the mask is worn, it can always be kept clean.

In addition, the antimicrobial mask using the gift mesh according to the present invention has a merit that has a permanent antimicrobial function as a functional mask that can be prevented from spreading his or her respiratory diseases to others, especially as a mask for children.

In addition, the silver mesh of the present invention is because the inherent characteristics of the silver (Ag) remains as it is excellent antibacterial and conductivity can be used as a digital yarn (conductor), such as antibacterial mask or smart clothing, and excellent in electromagnetic shielding and antistatic Has an effect.

Referring to the silver mesh of the present invention and the antimicrobial mask using the same with reference to the accompanying drawings as follows.

First, with reference to the accompanying Figures 1a, 1b, 2 and 3 will be described with respect to the silver and silver twisted yarn applied to the gift mesh of the present invention.

1A and 1B are diagrams showing a covering relationship between the examination and winding of the silver twisted yarn using the gifts and the gifts applied to the present invention, respectively, and FIG. 2 is a screening and winding yarn of the silver twisted yarn applied to the present invention. Is a diagram showing a form twisted with each other, Figure 3 is a schematic diagram showing the implementation of the covering yarn using the twisted yarn of FIG.

The silver-ply twisted yarn 100 applied to the present invention, for example, the covering yarn, is a silver alloy containing pure silver (Ag) (99.99%) or copper (Cu) by using a directional solidification method, as shown in FIG. After casting from the wire rod, the cast wire rod is formed into a microfiber by a drawing process, and at least one strand is formed by using a silver thread 22 (FIG. 1A) having a diameter of 0.015 to 0.05 mm as the screening 20, It is covered with the adverb 10.

First of all, a silver alloy microfiber having a diameter in the range of 50 to 70 μm may be obtained, for example, according to the manufacturing method of the silver alloy microwire proposed by the applicant in patent 879815.

The silver alloy fine wire is cast from a silver alloy wire so that the grain boundary is horizontally disposed in the drawing direction by a directional solidification method of the silver alloy consisting of 0.1 ~ 10wt% copper (Cu) and the remainder substantially silver (Ag) When drawing out the silver alloy wire rod, a microfiber having a diameter of 50 to 70 µm is obtained.

The silver alloy micro fine wire has silver (Ag) as a main component and contains 0.1 to 10 wt% of copper (Cu) so that the fine wire can be easily processed. Alloyed to be easily made.

On the other hand, in general, the well-known silver microfiber manufacturing technology is not finer wire processing to less than 0.07mm in diameter in the case of pure silver, even if possible to less than 0.07mm in diameter can not be made of long fibers and the workability is high due to high disconnection rate there was.

In addition, when the diameter is 0.05mm or more, because of the stiffness of the metal, it is difficult to use it as a joint yarn because it is not as flexible as a fiber.

Moreover, due to the limitation of the ultrafine yarn manufacturing technology of pure silver or silver alloy as described above, it was conventionally considered to use a relatively thick diameter, which is a material cost burden because a large amount of silver is used, the diameter at the same weight As this increases, antimicrobial activity decreases.

As the finer wire is finer, the surface area can be increased in a small amount, and as a result, the antimicrobial activity of silver is increased. If the use of silver 70㎛ or more compared to the antimicrobial effect appears to be the amount of silver used is relatively large.

The silver alloy ultrafine wire obtained according to the above patent No. 879815 could not manufacture a microfine yarn having a diameter of 0.05 mm or less, but the present inventors further improved the manufacturing technology of silver microfine yarn to be used as a yarn in the present invention. To be able to manufacture a silver of 0.05mm to complete the present invention.

In the present invention, by using 99.99% pure silver in addition to the silver alloy described above to produce a silver yarn 22 having a diameter of 0.015 to 0.05mm and use it as a screening or yarn.

The silver yarn 22 may apply one or more strands as yarn, depending on the use of the fabric or knit fabric made using the twisted yarn.

The silver yarn 22 must have flexibility in order to be used as a fiber. In the case of the silver yarn 22 has a diameter of 0.05mm or more, the metal has stiff characteristics. Therefore, in order for the silver yarn 22 to be flexible like a fiber, it is preferable to make diameter less than 0.05 mm. In other words, in the case of the silver yarn 22, the larger the diameter, the greater the amount of silver (Ag) is used, but the antibacterial effect is also reduced. Therefore, in order to exhibit the same antimicrobial effect, a larger amount of silver (Ag) is required, which causes a price increase, which leads to an overall cost increase.

In addition, it is not easy to make the diameter of the silver yarn 22 0.015 mm or less in the present technology, and when the thickness is too thin, the silver yarn 22 is too weak, and thus there is a problem in that disconnection occurs during the manufacture of the twisted yarn. Therefore, the diameter of the silver yarn 22 of the present invention is preferably set within the range of 0.015 to 0.05 mm.

The winding yarn 10 may be applied to a fiber yarn made of any one of natural fibers or synthetic fibers.

For example, the natural fiber may be made of any one of Hanji, PLA (poly lactic acid; biodegradable fiber), cotton, hemp, wool, and silk.

For example, the synthetic fiber may be a fiber made of any one of nylon, polyester, polyvinyl chloride, polyacrylonitrile, polyamide, polyolefin, polyurethane, and polyfluoroethylene.

Furthermore, the synthetic fiber can use the fiber obtained using the following polymer.

Polyethylene-based resins such as low density polyethylene resins (LDPE), ultra low density polyethylene resins (LLDPE), high density polyethylene (HDPE), ethylene-vinylacetate resins (EVA), copolymers thereof, and the like.

Polystyrene-based resins such as HIPS, GPPS, SAN, etc.

Polypropylene-based resins, for example HOMO PP, RANDOM PP, copolymers thereof

Transparent or ordinary ABS (acrylonitrile-butadiene-styrene terpolymer)

-Rigid PVC

Engineering plastics such as nylon, PRT, PET, POM (acetal), PC, urethane, powder resin, PMMA, PES, etc.

In addition, the natural fiber or the synthetic fiber can use other well-known fiber other than the above-mentioned fiber material.

Meanwhile, as shown in FIG. 2, the first ply-twisted yarn applied to the present invention casts a wire rod by using a directional solidification method of silver or a silver alloy, and then first examines a silver yarn having a diameter of 0.015 to 0.05 mm made through a drawing process. The first composite twisted yarn 200 can be obtained by using the yarn 20 as a fiber yarn made of any one of natural fibers and synthetic fibers as the second screening yarn 10a and then twisting it with a twisting yarn.

In this case, the natural fibers or the synthetic fibers used as the second examination 10a may be the same or similar to the above examples.

In addition, in the present invention, as shown in Fig. 3, the first twisted yarn 200 obtained by joining the fiber yarn made of natural fibers or synthetic fibers to the silver yarn is used as a screening, and the fiber yarn made of any one of natural fibers and synthetic fibers is recommended. The second twisted yarn 300 may be obtained by using the same as the cooking 10b to cover it.

In the production of the silver mesh using the above-mentioned silver and twisted yarns, it is possible to use silver yarn alone or a twisted yarn jointed with a metal (for example, copper) or a non-metal (for example, Hanji, PLA, PVC, etc.). One or more strands are applied to form a silver mesh.

In order to insert such a silver mesh into the antimicrobial mask and have flexibility such as fibers, the diameter of the silver thread is preferably 0.015 to 0.05 mm as described above.

Therefore, the number of meshes is preferably 50 to 400 meshes when the mesh of the present invention uses a silver yarn of 0.015 mm to 0.05 mm.

If the mesh is made less than 50 mesh, the thickness of the silver becomes more than 0.5mm compared to the thickness of the silver. Therefore, the shape of the mesh cannot be maintained, and thus the value of the mesh is inferior. As a result, the use of a large amount of gifts leads to an increase in the price of the product, which is uneconomical. In other words, the higher the mesh, the narrower the distance between the silver yarns, so the flexibility is lost. Therefore, it is also difficult to produce an antimicrobial mask using the silver mesh.

The silver mesh can be produced in various ways by giving 100, 150 or 200 mesh using the above-mentioned silver yarn and silver twisted yarn as weft and warp yarns.

For example, the production method of the silver yarn mesh is a method of using a warp yarn and a weft yarn by silver metal yarn or silver-bonded yarn alone, and a warp yarn uses a fiber yarn (at least one of natural fibers and synthetic fibers) and / or a metal yarn other than silver yarn. The weft yarn is a method of using silver yarn or silver twisted yarn alone, the warp yarn is used alone or silver twisted yarn alone, and the weft yarn is made of fiber yarn (at least one of natural fiber and synthetic fiber) and / or metal yarn other than silver metal yarn. In the case of using a silver metal yarn and a silver twisted yarn as a warp and / or weft yarn, a method of mixing silver metal yarn and a silver twisted yarn, etc. may be used. It is also possible to insert at intervals.

In this case, when the silver and silver twisted yarns are inserted at intervals, the interval is preferably 0.02 mm to 10 mm or less.

When using silver and silver twisted yarns as warp and / or weft yarns during the production of the silver mesh, insert one or more strands using wires (threads) of metal and nonmetal other than silver as the warp and weft yarns between the silver and silver twisted yarns. In the case where the space between the silver twisted yarns is dropped, the distance between the silver yarn and the silver twisted yarn is preferably 0.02 mm to 10 mm or less. If less than 0.02mm exceeds the sufficient amount to show the antimicrobial activity, the price rises, and when it exceeds 10mm, the distance between the gift and silver twisted yarn is too far to show the antibacterial and bactericidal power.

It is also possible to obtain functional color fiber yarns by dyeing the second twisted yarn 300 of FIG. 3, and the fabric woven by using the twisted yarns 100, 200, and 300 as warp yarns and weft yarns, and loops into yarns. It is possible to weave silver twisted yarn knitting fabrics which are made by intertwining each other while forming new rings by threading the loops.

Examples of the antimicrobial mask using the silver mesh and silver twisted yarn knitted fabric according to the present invention will be described with reference to FIGS. 4A and 4B.

Referring to the cross-sectional view of FIG. 4A, the antimicrobial mask 41 is an example in which the silver mesh filter layer 42 is inserted between the inner skin 43 and the outer skin 44 using the silver mesh or silver twisted yarn knitted fabric described above. Referring to the cross-sectional view of 4b, the antimicrobial mask 51 is an example in which a silver mesh or silver twisted yarn knitted fabric 53 is used for the endothelial and / or the outer skin and a silver mesh filter layer 52 is formed therebetween.

In addition, the antimicrobial mask of the present invention, in addition to the structure of Figure 4a and 4b described above using a silver mesh or silver twisted yarn knitted fabric and the inner skin and inserting the silver mesh or silver twisted yarn knitted fabric between the shell and the inner skin. It is possible.
