As is widely known, copper is one of the metal materials that human beings have used for a long time. It is rich in malleability, high in conductivity, and added to low carbon steel to give corrosion resistance without vulnerable steel. There are a variety of physical and chemical properties, such as to prevent the occurrence of, has been known as a very useful metal often used widely in the electrical, electronic, mechanical industry.

However, it is known that such copper has a bactericidal action which has not been scientifically understood sufficiently called a microscopic action. This trace metal action has been used in various medical devices since copper was known as a sanitary metal in the medical field since a botanist named Negeri in 1893 discovered that 10 million copper ions act to kill algae. In addition, it has been about 6,000 years since humans have actually used copper, and human beings have empirically made various objects by using micro-actions in various fields and used them in daily life. For example, Dongju Electronics, Dongdaeya, fairy tales, door handles are good examples.

On the other hand, as an example of applying the trace action of copper, there were copper fibers in which anoxic copper wires having a diameter of 10 mm to 20 mm were continuously increased over time with a drawing machine and finally tapered to a diameter of 30 μm. The copper fiber has a surface area in contact with water or air is maximized, so that a small amount of copper, which has been exerted for a long time, occurs rapidly, and thus sterilization ability or residual chlorine removal ability is maximized. For example, socks and shoe insoles containing athlete's foot preventive copper fibers are used. In addition, ultra-fine copper fibers are used as sterilizing filters in some foreign large home appliance companies that produce air cleaners and humidifiers.

The effect of these fibers on airborne bacteria or bacteria in the water was tested by Northview Pacific Laboratories Inc., a designated inspection agency of the US Food and Drug Administration (FDA), and air was 91.9% in 3 hours. Good results were reported with 93.8% bacterial reduction and 99.9999% with water.

In addition, a test comparing the screen mesh type filter made of the same material with the conventional membrane filter was conducted by Northview Pacific Laboratories Inc., and the air pump coupled to each filter was operated for 2 hours. Next, each filter was incubated in a bacterial incubator, the average number of bacteria decreased by 82.9%.

In addition, anyone can confirm that chlorine is injected into the water cup filled with water, and then the copper fiber is inserted and wetted to completely remove the chlorine by the micro action of the copper fiber.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
