Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the construction of a button for clothing having antibacterial properties.

0002

[Conventional technology]

Conventionally, buttons for clothing have been used for the purpose of fastening clothes or for decoration. Buttons have been manufactured using natural or artificial materials. Shells, bones, horns, etc. are used as natural materials, and various plastics are used as artificial materials. Stick materials, glass materials, metal materials, etc. have been used.

0003 Conventional buttons like this can only be used in extremely limited areas such as clothing. However, since it only accounts for 1% of the total It wasn't done.

0004

[Problem that the idea aims to solve]

However, the above-mentioned buttons are often touched by human hands, and are difficult to use when wearing clothes. In most cases, it is exposed to the outside and is used, so in reality, mold, bacteria, Various types of fungi such as bacteria can also attach and multiply. Also, the growth of this fungus Because of this, clothes are rarely worn all the time throughout the year, and are stored in dark places such as chests of drawers. If preserved, the frequency of reproduction will be extremely high. Contact with buttons on which fungi have attached and grown in this way is a direct cause of infection. It can also cause damage to human health.

[0005] In addition, the following attempts have been made to maintain the antibacterial properties of this button. There are difficulties. In other words, especially organic antibacterial agents that have traditionally been used for industrial purposes, Although many drugs have excellent efficacy, they lack safety and cannot be used directly by humans. It is not suitable for use as a button with many opportunities for contact. Also permitted under the Food Sanitation Act Antibacterial agents used as preservatives are generally dissolved in a solvent. Therefore, when used for buttons, only short-term effectiveness can be expected. Therefore, it is not suitable for use in buttons that are used every few years. We also have button material Manufacturing conditions such as heat resistance during processing as a material must also be considered.

[0006] The purpose of this invention is to withstand molding conditions, effectively produce antibacterial effects, and to last for a long time. To provide a button that maintains its effectiveness over time and has antibacterial properties that are safe for use. It is in.

[0007]

[Means to solve the problem]

Therefore, in order to achieve the above-mentioned purpose, this invention was developed to develop a button with antibacterial properties. It was constructed as follows. In other words, the granular antibacterial agent is kept uniformly dispersed in the button forming material. It is characterized by being forced to become.

[0008] Considering the above-mentioned structural characteristics, the suitable material for forming the button is antibacterial agent granules. Plastic materials and gold that can be mixed inside or on the surface during the button formation stage Materials, etc. This plastic material includes polyester resin, acrylic resin, and nylon resin. resin, lactroid resin, ABS resin, etc., and metal materials such as zinc and tin. Examples include materials with low melting points, such as alloys with

[0009] In addition, as an antibacterial agent, it has low toxicity to the human body, and is effective at the button formation stage. It maintains its original granular shape before and after, for example, copper, silver, zinc, etc. Resistant to any antibacterial metal powder or heat-resistant carrier such as calcium phosphate. It is preferable to use a material obtained by exchanging and adsorbing bacterial metal ions.

0010 In addition, the uniform dispersion of antibacterial agent particles in the button forming material is similar to that of plastic materials. If it is a forming material, an appropriate dispersant is added during the process of forming it into a button. Obtained by adding . Specifically, polyester resin is used as the forming material. When using a dispersant such as N,N-dimethylformamide or sodium methylate, It can be used as In addition, if the button forming material is a metal material, the metal The temperature activity of metal material atoms or molecules in the molten state of the material can be utilized. Therefore, it is possible to obtain the same uniform dispersion structure as above by simply mixing antibacterial agent granules. Wear.

[0011]

[Effect]

The button configuration according to the present invention produces the following effects. Since the antibacterial agent particles are uniformly dispersed within the button, the antibacterial effect is maintained throughout the button. Evenly spread over the entire surface of the tube.

0012 In addition, antibacterial particles located near the surface of the button have a strong antibacterial effect. It has a fungal effect on the button surface, and its presence increases the distance from the button surface. The effect weakens as the temperature increases. Please note that antibacterial agents that are not present near the surface of the button When the forming material is plastic, the antibacterial effect depends on its molecular structure. In addition, if the forming material is a metal material, the micro pores that occur during casting. It is demonstrated through.

[0013] In addition, the uniformly dispersed structure of this antibacterial agent granule allows the antibacterial agent to be deposited in a very small amount on the button surface. Most of the antibacterial particles contained in the button are absorbed by the material forming the button. It is in a coating state. Therefore, direct contact with the button is also harmful to the human body. does not cause any harm due to its antibacterial properties.

[0014]

【Example】

(Example 1) The button of this example was manufactured by the following method. First, the button forming material raw material was prepared by mixing the following ingredients at a temperature of 40℃. Manufactured. Polyester resin raw material liquid 75% by weight Antibacterial agent 10% by weight Dispersing agent (DMF) 5% by weight The above antibacterial agent is made by exchanging and adsorbing silver ions to calcium phosphate powder. It is. Next, this forming material raw material is cured and formed into a plate shape at a temperature of 40 to 50°C. Next, this resin plate is cut out, and further processed by cutting, polishing, drilling and Buttons were obtained after polishing.

[0015] The button 1 thus obtained is shown in FIGS. 1 and 2. As shown, This button 1 has antibacterial agent particles 3 uniformly dispersed in its resin forming material 2. Contains and retains. Note that 4 is the front surface, 5 is the rear surface, and 6 is the clasp. This is an opening for the pinning thread.

[0016] Further, FIGS. 3 and 4 show the configuration of a control button that is not included in the present invention. In the illustrated control button 11, antibacterial agent particles 13 aggregate in the middle part inside the resin forming material 12. It is maintained in the state. In addition, the control button 21 has antibacterial agent particles 23... and its resin forming material 22. It is held unevenly in a partially aggregated state on the surface of the . In addition, 14 and 24 are The respective front surfaces, 15, 25 are the respective rear surfaces, and 16, 26 are the respective apertures. Ru.

[0017] In the control button 11, most of the antibacterial agent particles 13 are on its front and rear surfaces 14, Since it is almost completely isolated from 15, it is impossible to expect an effective antibacterial effect. At the same time, there will be a concentration of particles inside the button, so the structure of the button will be It has the disadvantage of weakening itself.

[0018] In addition, in the control button 21, the antibacterial agent particles 23... are near the front surface 24 or the rear surface 25. When present, its antibacterial effect is effectively exerted, but its presence concentrates on the surface area. Therefore, people may come into contact with the antibacterial agent granules 23, and the surrounding area may be affected by oxidative deterioration of the antibacterial agent particles 23 itself. The antibacterial agent particles become ineffective due to environmental influences, and the antibacterial agent granules are easily released due to surface abrasion. There is a risk that the antibacterial effect will last for several years, so it is impossible to expect that the antibacterial effect will last for several years. In addition, the presence of antibacterial agent particles near the surface prevents coloring of buttons. There are drawbacks such as being the cause of poor performance.

[0019] The various drawbacks of the contrast buttons 11 and 21 as described above are the same as those of the button according to the present invention. 1 does not occur. That is, the antibacterial agent particles 3 are uniformly dispersed in the resin forming material 2. , and its antibacterial action is also scattered on its surfaces 4 and 5, as described later. Effectively demonstrated. Furthermore, this antibacterial effect exists near such surfaces 4 and 5. Even if the antibacterial agent granules 3... are mainly responsible, other antibacterial agent granules 3... are also responsible for the resin forming material. Depending on the molecular composition of 2, it exerts its antibacterial action on surfaces 4, 5. Also, this antibacterial agent The uniform scattering structure of the particles 3 prevents the button 11 from becoming weakened and discolored. This eliminates the effects of antibacterial agents and reduces the chance of human contact with antimicrobial agents.

Next, the antibacterial effect of Button 1 was tested by the following means. First, a test solution was prepared as follows. In other words, Escherichia coli (IFO 3301) frozen and preserved on a heart infusion agar medium was cultured at 35°C for 20 hours, two to three colonies of this cultured E. coli were scraped off with a platinum loop, and this was added to 30 ml of infusion broth. The cells were cultured with horizontal shaking at 35°C for 17 hours. Next, this cultured E. coli was added to 1/2000 volume of the phosphoric acid buffer solution to give a bacterial count of 5×10 ⁵ cells/ml, and this was used as a test solution.

[0021] In addition, antibacterial activity was measured as follows. First, the button 1 to be tested is placed in a sterilized container with a cap, and the surface 4 of the button 1 is 5 ml of the above-mentioned test solution was applied onto the container, and the inside of the container was sealed with a cap to serve as a sample. Next, this sample was divided into static cultures at 25°C for 6 hours, 24 hours, and 48 hours. fed. In addition, buttons of the same shape and size made purely from the same material can be used in the same manner as above. The cells were used as control buttons, and statically cultured in the same manner as above.

[0022] Next, count the colonies on the test button 1 and the control button surface. The number of E. coli bacteria was determined. Regarding the test buttons, the content of antibacterial agent granules 3 was 10% by weight, 20% by weight, and 20% by weight. Prepare samples of 30% by weight and 30% by weight, process them in the same manner as above, and use them as samples. I asked for These results are shown in Table 1 below.

[Table 1]

[0023] According to the results in Table 1, the button according to the present invention is not affected by the antibacterial agent. Although there is a limit depending on the content of tobacco, effective antibacterial action is achieved after a certain period of time. You can confirm that the function is being used, and also compare it with the control button. This effect is also judged to be significant.

[0024] (Example 2) The button in this example was obtained by the following manufacturing method. First, an alloy material of zinc and tin was brought into a molten state at a temperature of approximately 450°C. Next, copper ions are exchanged and adsorbed to calcium phosphate powder in this melt. A granular antibacterial agent is mixed in at a ratio of 7% by weight, and the molten material after this mixing is immediately boiled. The mixture was poured into a mold. Next, it is left to cool naturally, taken out from the mold, and subjected to surface polishing to become a finished button. Ta. We confirmed that this metal button also has the same antibacterial effect as the resin button 1 mentioned above. It was also confirmed that the effect lasted for a long time.

[0025]

[Effect of the idea]

Since the present invention is constructed as described above, it has the following effects. In the button according to the present invention, as mentioned above, the effective antibacterial action is spread over the entire surface. This is because it suppresses the proliferation or kills various types of fungi. It can be used hygienically. Moreover, its action lasts for a long time, matching the period of use as a button. Also, even if it comes into contact with the button, it will not cause any harm to people, so please use it for opening and closing. The function as a button is not impaired either.

[0026] In addition, the formed button maintains a certain strength and has the desired coloring. Since it can be obtained as a button, a variety of buttons can be obtained as before.
