Description

Antibacterial air filter that coated Silver

The present invention relates to an antibacterial air filter nonwoven fabric, and more particularly, contaminants collected in a filter, which is used for cleanliness of air flowing into a car interior, to lead to bacteria propagation such as mold and odor generation, thereby impairing the operating environment. In order to dissipate this, silver (Ag) with excellent antimicrobial effect is used to extinguish it, but the coating thickness of the antimicrobial material is reduced to reduce the cost, while the adhesive force can be increased for a long time. Because the drying method is not wet, the pores which are the main function of the filter can be maintained as it is, and the coating area is not limited to only one direction, and the coating part can be widely distributed through the pore passage to the yarn located inside. The antibacterial effect can be maximized to provide a comfortable driving environment. It relates to an antimicrobial air filter nonwoven fabric.

In modern society, with the increase of automobile production, the road environment is poor, the air pollution is in serious condition, and it is necessary to maintain a stable driving environment. The air flowing around the road and the interior of the car contains many malignant micro-materials such as road dust, asbestos particles, pollen and harmful gas substances such as Benzene, Toluene, Hydrogen Sulfide, Formal dehyde and Ammonia. Prolonged exposure to particles having a particle size of 3 microns or less of these particles causes respiratory diseases and various kidney diseases. Therefore, the product invented is a cabin air filter, which is installed in the indoor air duct of a car, and has performed a successful role by performing a filtering function that filters outside air at all times even when an air conditioner or a heater is not operated.

However, external air inflow devices such as air conditioners and heaters of vehicles have structural disadvantages, and existing filters are limited to collecting pollutants, and they are limited in their ability to eliminate bacteria propagation and odor generation such as molds. There was a need for a new antimicrobial air filter that would naturally protect health from contaminants and maintain excellent antimicrobial activity for a long time.

Therefore, many devises such as using antimicrobial fibers, adding activated carbon, or using a metal net, or adding metallic or antimicrobial materials in the nonwoven fabric manufacturing process have been proposed.

The designed filter can be divided into four stages and describes the characteristics and disadvantages of each product.

The first step is the method of bonding plastic or metal mesh to the filter. The air filter is bent for dust collection efficiency, but the mesh is easy to bend, but it has the disadvantage of covering the nonwoven fabric to create intake and exhaust resistance. In the case of the method (Patent Publication 10-264822) and the method using the polymer carbon film (Patent Publication 10-350361), the collecting ability is high, but the antibacterial ability is lowered, and the risk of powder leakage and the loss of air permeability after saturation of harmful substances It is a disadvantage.

The second step is that the activated carbon filter (Patent Publication 2003-0010848) coated with a photocatalyst has a disadvantage in that the deodorizing effect is lowered by partially embedding the deodorant or photocatalyst in the fiber layer by using a predetermined binder mixture, and the silver compound and zeolite The catalyst with the catalyst (Patent Publication 2003-0039811) is impregnated with silver compounds and then immersed in zeolite again through a high temperature drying step, so that the silver is screened and antimicrobial effect is difficult to expect. Environmental problems are also caused by wastewater treatment.

The third stage is a cabin air filter that generates negative ions using artificial electricity (Utility Model Registration 20-0296828). As a number of filters and lamps are placed in a limited space, the airflow is not only reduced, but also a burden on the consumer is increased. Since it may lead to a reduction in the life of the battery and there is no generation of harmful cations to the human body, there is a problem that causes the headache rather.

The final fourth step is the case of nonwoven fabric air filter containing anion generating material and its manufacturing method (Patent No. 2003-0015646). The mineral that generates anion is a kind of newly discovered granite. Non-woven fabric is manufactured through high temperature, pressing and drying process after application to yarn. This method is also powder, so no matter how high or high temperature treatment is, the risk of powder leakage and loss of air permeability after saturation of harmful substances Is that.

Recently, the method of adding metallic to yarns and the application of antimicrobial material from the initial stage of the nonwoven fabric manufacturing process have been increased as in the fourth step, and when the finished nonwoven product is devised, it is immediately applied to develop a different antimicrobial material. As more and more companies come up with better products, they are seen as ways to overcome the crisis of non-woven fabric manufacturers, and they are also at the limit of the technology that cannot be added to the finished product filter. It shows the cross-section that has been reached, and on the other hand, nonwoven fabric manufacturing technology has been a turning point for further development. However, this wet method has disadvantages of environmental problems, complicated manufacturing processes and working conditions, and excessive manufacturing costs.

In addition, household air purifier filters (POS 20-0343303) require 4 to 5 filters, and can easily obtain electricity or power in an unrestricted space, so there is no concern about breathability and antibacterial properties, but many filters are frequently used. This is a cost burden to replace, which is unsuitable under the limited space conditions of the vehicle, and the manufacturing cost can be greatly reduced if the filter using the present invention is used in an air cleaner filter.

It is known that the electrical load of silver ions emitted by metal silver removes germs and that no germs or viruses on the ground have survived for more than six minutes by contact with silver. Traces of efforts to apply such silver can be guessed from various filter design examples, and only a few of them were examined. Silver-alginate antimicrobial agent for antibacterial fiber (Patent No. 2001-0001271) and structure of hepa filter (utility registration) 20-0343303) and various filters used for air cleaners and filters based on silver compounds and zeolites (Patent Publication No. 2003-0039811), which are not filters but are used for manufacturing silver paper and silver wallpaper for other purposes (Patent Publication) (2001-0069799), a method of manufacturing silver dry products (Patent Publication No. 1998-087632), and a method of manufacturing inorganic antimicrobial agents using silver, yellow soil, and ceramic pastes (Patent No. 2001-0044617). Not only did it fail to raise, but the silver component was buried, recessed or finely mixed, which was insufficient to apply and display at 100%.

This is due to the fact that complex manufacturing processes and many hazardous chemicals were only possible in the process, and insisted on deriving only a wet method that would lead to high-level process selection problems and environmental problems through chemical reactions and analyses.

The present invention solved the problem by devising a method of coating the filter by vacuum evaporation method by adopting the drying method that can express the antibacterial function 99.99% using silver (Ag) excellent in sterilization effect. The function is a big difference that can not be compared with the prior art. In addition, the surface of the filter emits silver, which not only satisfies the user's purchase needs, but also greatly improves the reliability of the product image by the consumer for the effect of the silver effect, and is a new antibacterial filter that opens a new chapter in the filter industry. Will be featured as a product.

The present invention has been made to solve the above-mentioned conventional problems is to increase the adhesive strength by etching the surface of the yarn of the nonwoven fabric by coating the silver (Ag) with a plasma.

In addition, the thin coating of the antimicrobial material to be coated on the non-woven fabric while maintaining the pores of the life of the air filter as it is to distribute the antimicrobial material widely to maximize the antibacterial, deodorizing efficiency and to ensure long-lasting.

In order to achieve the above object, the surface of the nonwoven fabric is etched in vacuum to form a thin thickness with irregularities, and the antimicrobial material of silver (Ag) is plasma-coated on the etched surface to coat with antibacterial air filter nonwoven fabric. Is to provide.

Hereinafter, the configuration of the present invention according to the embodiment with reference to the accompanying drawings in detail as follows.

Figure 1 is a schematic diagram of a state for constructing the present invention, showing a state of coating the antimicrobial material on the nonwoven fabric as a spout, Figure 2 is a nonwoven fabric using a yarn (staple fiber) configured by one embodiment of the present invention This is an enlarged cutaway perspective view by extracting a part, the yarn or non-woven fabric is etched to a predetermined thickness to form an unevenness and then coated silver (Ag), an antimicrobial material on the etched surface.

As a perspective view, the yarn 33 on the completely opposite side is divided from the uncoated portion of the front yarn 31 as well as widely coated to the rear yarn 32 through the pores. 34) and the uncoated nonwoven fabric layer 35, which is characterized in that the antimicrobial action and the ability to capture is maximized at the same time, and the shape of the existing filter is maintained as it is.

Figure 5 shows the completeness of the cabin air filter 50 consisting of an antibacterial filter 51 installed in the vehicle intake air system and the frame 41 for supporting the filter.

The present invention was applied to plasma, which is one of the methods to reduce the characteristics of the low temperature environmental factors and the fineness of the process and the deformation and modification of the base metal among the surface treatment methods of metals and polymers as a drying method. Plasma refers to a state in which electrons constituting atoms, molecules, or compounds move out of the bondage of the nucleus, respectively, and the present invention creates a high-pressure vacuum environment in the reactor, and then supplies activated gas (Ar) and oxygen gas into the reactor to prevent antibacterial activity. When accelerated energy (Discharge) is applied to the cathode 2 to which silver 10 of the material is attached at a voltage of about 3V, an electric field is formed in the reactor, while the outermost electrons sputter out of the orbit. Becomes a positive charge and electrons of a negative charge are generated. A large number of charge ions and electrons are electrically neutral, and the particles interact with each other to emit a unique light (plasma state) and high reactivity. At this time, since gas atoms or molecules can be excited, dissociated, and ionized by electrons constituting the plasma in the reactor, chemical reactions are performed on silver (10), which is an antimicrobial substance on a solid surface which is physically expelled by energy transfer and is in contact with the plasma. It is a method of depositing and coating on the target nonwoven fabric. At this time, if pressure and voltage are important process variables, if the material to be deposited is a non-conductive material such as a nonwoven fabric, D.C. It is impossible to maintain plasma only by using power, so it is possible to release secondary electrons by collision of ions only by using regular AC power (R.F Discharge), and it is possible to maintain plasma continuously.

On the other hand, the electrons and ions in the plasma are active circular motion in the direction perpendicular to the magnetic field by applying a magnetic field, it is possible to hold the plasma to one side and to concentrate the density of the plasma non-woven fabric of the present invention (1) can be coated to the front yarn 31 and the back yarn 32, and can be divided into a coated nonwoven fabric layer 34 and an uncoated nonwoven fabric layer 35, thereby maximizing antimicrobial action and capturing ability at the same time. It is.

In other words, when the cathode 2 generates electricity and hits an atom, electrons in the atom pop out, which becomes positive (+) and electron becomes negative (−). Due to the vigorous movement in the plasma, this atom strikes the plate of the antimicrobial material 10, causing the particles (Ag) of the antimicrobial material to be expelled, that is, the emission of secondary electrons. 32) to stick to the strands.

As such, the nonwoven fabric 1 of the present invention is suitable for a cabin air filter for an air filter, and also shows excellent antibacterial and deodorizing effect as an air purifier, an air conditioner, and a mask filter paper.

In addition, the use is classified according to the thickness, material composition and manufacturing method of the nonwoven fabric, and if you use the present invention with various characteristics appropriately, the following product development is possible.

Non-woven fabrics can remove the mites that inhabit clothing when used as a warming material for outer fabrics and lining materials and winter coats, which enables their original form to be maintained even after frequent washing and dry cleaning.

Non-woven fabrics can be used to clean polluted air from windows outside when used on ceilings, trunks, floors and mattresses inside cars, and to block indoor pollution of bacteria caused by contaminated shoes. .

As a shoe material, it can protect the health of the feet with excellent antibacterial and deodorizing effect on sneakers or shoes that smells a lot for insoles.

Nonwovens are a medicinal material that is effective in burn wounds and will be effective in hospital gowns, masks, hats, and patient bed sheets.

Hygiene uses silver coated materials for disposable diapers and women's sanitary napkins, which are not only harmful to the human body, but also have antibacterial and deodorizing effects, as well as pharmacological effects on the skin of the human body. You can relax and relax your mind and body to improve your health.

For home use, when applied to bed mattress, clothing storage cover, wallpaper blanket, living room carpet, etc., it effectively removes harmful substances such as ticks, viruses, molds, and so on, and can protect family health.

In particular, new house syndrome, which has recently emerged as a serious social problem, causes various allergic diseases such as atopic dermatitis and asthma by volatile organic compounds emitted from building materials, wallpaper, and new furniture of residential buildings. In weak people, prolonged exposure to chemicals can cause fatal diseases such as cancer. This problem can be easily solved by using the silver coated antimicrobial nonwoven fabric of the present invention as a draft paper before wallpaper construction.

The nonwoven fabric is applied not only to the role of the filter but also to various fields as listed above. The nonwoven fabric is thinned by coating the antimicrobial material after etching, while the role of the conventionally developed filter can be obtained as in the conventional art. As the surface is made of unevenness due to etching, it has excellent adhesive strength, so the antibacterial material does not fall even after frequent use and washing, and it has a characteristic of lasting antibacterial effect for a long time.

Therefore, as mentioned above, while the adhesive layer of the antimicrobial material on the nonwoven fabric is thinner, the adhesive strength is increased and the cost can be reduced, and the disadvantages such as environmental problems such as wastewater treatment and lack of flexibility compared to the wet coating method are overcome. According to the characteristics of the nonwoven fabric, the softness can be maintained as it is, which is easy to bend, and because the coating work is performed in a vacuum state, the yarn is placed inside through the passage of the pores without any loss of pore blockage as well as the coated front. The coating can be applied to a wide range, and the distribution of antimicrobial material is wide, which maximizes the antimicrobial effect and can be maintained for a long time. In addition, since silver is emitted from the outside, it is possible to satisfy the user's desire to purchase and can greatly improve the reliability of the product image by the consumer about the effect of the silver effect.
