Description

r\ CLOTH STRUCTURE
Technical Field
The present invention relates to a cloth structure, and more particularly, the present invention relates to a cloth structure containing a silver-coated textile and which is capable of providing disinfectant and antibacterial function and effectively intercepting electromagnetic waves.
Background Art
As modern society is industrialized and highly developed, environmental pollutions including air pollution, water pollution, etc. increase and thereby, various diseases break out. Therefore, modern people are concerned more about their health than before and demand products grown by organic agriculture or health supplementary foods. In addition, various products beneficial to health are highlighted. Recently, following such trends of consumers, many health products such as clothes, shoes, etc. are made to exhibit disinfectant and antibacterial function.
As materials used in these health products, natural materials, for example charcoal, yellow soil, jade and mugwort are widely used. Recently, health products containing silver(Ag) are produced. From ancient times, Silver(Ag) is known as a stable metal that does not change even when several decades have passed. Its metallic characteristics are such that it is hardly ionized but rather easily reduced, that is, it does not readily lose an electron, and it is a highly stable metal that tends to exist in its natural state. Meanwhile, silver ion(Ag+) released from silver has such superior disinfectant and antibacterial effects that it can disrupt respiration and propagation of bacteria. Currently, antibacterial fiber using silver has been developed and widely used. Such fiber is typically prepared by absorbing or spray-absorbing atomized silver onto fibers using their electrical polarity.
When applying charcoal and jade to clothes for disinfectant and antibacterial effects, generally charcoal and jade are atomized and sealed in a cloth, which is then fixed to the clothes, or atomized and then directly attached to the clothes. However, according to these methods, the increase in volume gives a poor appearance and causes inconvenience in use. In terms of preparation process, they require complex processes and large process cycle times.
Also, the powders of charcoal and jade tend to escape while a user wears the clothes or during washing of the clothes. Therefore, there occurs a problem regarding durability. Further, since the powders having disinfectant and antibacterial effects are not evenly distributed, their functions are not uniformly exerted.
In addition, silver has an electromagnetic wave shielding effect. Nevertheless, there are no conventional cloth structures using silver which can effectively shield the electromagnetic waves emitted from electric and electronic appliances and communication equipments.

Best Mode for Carrying Out the Invention
Reference will now be made in greater detail to a preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings.
Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1 shows a perspective view having cross-sections of a cloth structure according to the first embodiments of the present invention. As shown in Fig. 1, the cloth structure according to the first embodiments of the present invention comprises a silver coat textile layer(lθ) comprising a textile(12), a first silver coat layer(14) coated with silver ion(Ag+) to a predetermined thickness on the upper surface of the textile(12) and a second silver coat layer(16) coated with silver ion(Ag+) to a predetermined thickness on the lower surface of the textile(12), and a first adhesion layer(20) formed with a desired material to a predetermined thickness over a surface of the silver coat textile layer(lθ). The silver coat textile layer(lθ) is formed by charging an electrolytic bath having metallic anode dipped therein with an electrolyte containing silver ions and continuously passing a textile through the electrolyte. Here, by making direct current flow through the metallic anode a constant voltage is maintained across the textile. The silver ions from the anode move and are electrodeposited to upper and lower surfaces of the textile. However, the coating process of the silver coat textile is not limited to the above-described method but can be carried out using various equipments according to various methods.
Then, the first adhesion layer(20) is formed over the silver coat textile(lθ). The bonding of the first adhesion layer(20) to the silver coat textile(lθ) is carried out by means of an adhesive, by a thermal pressing process including applying heat to the first adhesion layer(20) and attaching the first adhesion layer(20) to the silver coat textile(lθ) using a pressing means such as a roller, or by stitching with a coupling thread. Meanwhile, in the cloth structure according to the first embodiment, the first adhesion layer(20) can be made of soft plastics, rubber or foamed polyurethane, which can be formed into a structure of a shoe or a shoe sole, or cut into a shoe sole to be applied to a shoe cushion, as shown in Fig. 1. In these cases, since the first and second silver coat layers(14,16) perform disinfectant and antibacterial functions, hygiene of feet is improved and development of odor is prevented, whereby feet can be kept in good health.
Also, in the cloth structure of the first embodiment, the first adhesion layer(20) can be made of fabrics for underclothes (cotton, etc.), which are of benefit to human bodies. Fig. 2 shows a perspective view having cross-sections of a cloth structure according to the second embodiments of the present invention, wherein common reference symbols are used for the same portions shown in Fig. 1.
As shown in Fig. 2, the cloth structure according to the second embodiments of the present invention comprises a silver coat textile layer (10) comprising a textile(12), a first silver coat layer(14) coated with silver ion(Ag+) to a predetermined thickness on the upper surface of the textile(12) and a second silver coat layer(16) coated with silver io^Ag*) to a predetermined thickness on the lower surface of the textile(12), and a first adhesion layer(20) formed with a desired material to a predetermined thickness over a surface of the silver coat textile layer(l 0) and provided with pleats(22) at a predetermined interval. By this constitution, air spaces are formed between the silver coat textile layer(lθ) and the pleats(22) of the first adhesion layer(22) and provide thermostat function and cushioning function.
When applying the cloth structure according to the second embodiment to clothes, thermostat function of the clothes is improved and the weak cushioning function provides snug and comfortable feeling to a wearer of the clothes. Also, when the cloth structure with the first adhesion layer(20) of leather is used in production of gloves, the thermostat effect is doubled by the air spaces formed between the silver coat textile layer(lθ) and the pleats(22), as well as the disinfectant effect being improved.

In the bandage constructed as above, agents for treatment are applied under the pleats(22) and the cloth structure is attached to a body(29) of the bandage so that the first perforations(18) accords with perforations formed on the body(29) of the bandage. By this, ventilation through the first and second perforations( 18,26) is achieved, the disinfectant and antibacterial effects are provided by the silver ions of the first and second silver coat layers, and moreover, the contact between the agents and the wound by the pleats is improved, thereby maximizing the treatment effect.
Particularly, when the bandage constructed as above is attached onto joint parts of the body such as knee and elbow, since the pleats(22) formed over the first adhesion layer(20) are folded or unfolded(contract or expand) upon movements of the joint parts, the bandage can easily separated and firmly attached to the joint parts. Here, if a part of the bandage where the cloth structure with the pleats(22) is attached is also provided with pleats(28a) the contraction and expansion of the bandage can be achieved more smoothly.
