Description

The present invention focuses on the conductivity and antibacterial properties possessed by metals, selects materials that effectively bring out health effects and antibacterial effects, and forms them into yarns, and possesses metals by weaving the formed yarns into cotton cloth. The present invention relates to a technique for imparting a function to a cloth.

Conventionally, focusing on the conductivity and adsorptivity of carbon fiber, patent literature has been proposed that has effects on odor absorption effect, far-infrared radiation ability, antibacterial effect, etc., and used for fabrics and clothes to improve human constitution and promote health It contributes to. In addition, a conductive metal is newly attached to the carbon fiber to further improve the far-infrared radiation ability and antibacterial effect of the carbon fiber.
However, the values are not shown for the odor absorption effect, far-infrared radiation ability, antibacterial effect, etc. possessed by carbon fiber and metal-added carbon fiber, and the current situation is that the characteristics are not fully utilized. .

For example, Patent Document 1 provides cloths and clothes having an antibacterial effect that prevents the proliferation of bacteria and the like while maintaining the odor absorption effect and far-infrared radiation ability of activated carbon fibers. This is because it has a structure in which copper is attached to one side of a woven fabric woven with activated carbon fiber woven yarn, and the surface of the cloth which is not attached with copper is placed facing the human body. Because of the odor absorption effect of activated carbon fiber and the difference in the ionization tendency of carbon and copper, carbon and copper are electrically bonded through the moisture of sweat coming out of the body, and the same effect as the dissimilar metal bond is exhibited. Ionization is promoted to obtain a bactericidal effect and to improve far-infrared radiation efficiency. "
It is generally possible to electrically couple different metals on the same surface as long as they face each other and a part of the body touches the surface. However, as in this proposal, the surface where copper is not attached is placed facing the human body, and it is only through water that the copper is attached to the surface that causes metal bonding. It doesn't seem common. Furthermore, values for the odor absorption effect, far-infrared radiation ability, and antibacterial effect when the dissimilar metal bond occurs are not shown.

Therefore, the present invention focuses on the conductivity and antibacterial properties of aluminum and copper, and the difference in ionization tendency of both metals, and the texture of the cotton cloth is obtained by forming both metals into a thread or fiber and weaving them into the cotton cloth. The present invention provides a sewing fabric that retains conductivity, health effects and antibacterial effects without breaking the skin.

In order to achieve the above-mentioned object, the conductive fiber sewing fabric according to claim 1, wherein two linear aluminum foils are entangled with one core yarn to form an entangled yarn, and the aluminum foil entangled yarn and copper The fibers are woven alternately in the vertical and horizontal directions, and the interval between the fibers is set in a range of 10 to 20 mm that can be piezoelectric through human skin due to the difference in ionization tendency between aluminum and copper.

The conductive fiber sewing fabric according to claim 2 is characterized in that the core yarn is a polyester fiber.

In the present invention, the interlaced yarn and the copper fiber composed of the polyester core yarn and the aluminum foil are alternately woven into the cotton cloth, so that the dissimilar metals are joined through the human skin, and the pain of the knee, the arm and the like is reduced. Contributes to the relief of stiff shoulders. Moreover, if the polyester foil is cored and the aluminum foil is twisted, the brittleness of the aluminum foil is supplemented by the strength of the polyester fiber, and it is not easily cut. If the interval in which the aluminum foil entangled yarn and the copper fiber are alternately woven is set to a range of 10 to 200 mm, an appropriate piezoelectric state is obtained through human skin due to the difference in ionization tendency of both metals. .

An embodiment of the present invention will be described with reference to FIGS.

Initially, the manufacturing method and property of the entangled yarn comprised with a polyester core yarn and aluminum foil are demonstrated .
FIG. 1 is a schematic view of a entangled yarn composed of a polyester core yarn and an aluminum foil. The entangled yarn 1, a polyester core yarn 2 and the shaft core is formed of aluminum foil 3 on the wound was a structure helically thereabout. Since the tensile strength of the shaft core is larger than that of the aluminum foil, the aluminum foil is not cut. Since aluminum is a foil, it is a light conductive material, and since it is a foil, the current density is large.
The aluminum foil 3 is used by being cut to a width of 0.2 to 0.3 mm. This dimension is approximately the same as the diameter of the polyester core yarn 2, and is easy to wind around the core yarn, and has a width that is difficult to fray after winding. Further, a plurality of the aluminum foils 3 are used, and the polyester core yarns 2 are wound so as not to be seen. If the core yarn appears when the entangled yarn 1 is bent, it becomes partially insulative and the conductivity decreases.
Although the aluminum fiber has low flexibility and can be shaped, it cannot be put to practical use. However, the durable entangled yarn 1 was formed by using the polyester core yarn and the aluminum foil.

Next, the copper fiber corresponding to the entangled yarn 1 composed of the polyester core yarn and the aluminum foil will be described.
Copper is thinly stretched and formed as a fiber, is flexible, and has electrical conductivity, so that it can be a fibrous static eliminating material. This material also has natural antibacterial properties.
When copper and aluminum are joined, a potential difference is generated between different metals, and an electric field is formed in some form through human skin between copper and aluminum, which have a low ionization tendency. In other words, an electric field is generated between aluminum, which has a high tendency to ionize, and smaller copper, and the human skin provides a field of this electric field, but the formation of this electric field has health effects such as elimination of stiff shoulders. It becomes a factor to express.

Next, as for the cloth in which the entangled yarn 1 and the copper fiber are woven, the cloth used in the present invention is an interior fabric, clothes, pajamas or clothes lining, and a soft texture is a preferable material for human skin. ing.

Finally, a method for weaving the forming yarn into a cotton cloth in order to effectively bring out the health effect and antibacterial effect by focusing on the conductivity and antibacterial property of aluminum and copper will be described.
FIG. 2 shows a basic structure in which the interlaced yarn 1 and the copper fiber 5 are woven into the cotton cloth 4 in the vertical and horizontal directions, at equal intervals, and alternately, and forms a sewing fabric 6.
The entangled yarn 1 is electrically conductive yarns wrapped with aluminum foil to the axis of the polyester core yarn, copper fiber 5 is also a yarn exhibiting conductivity as well. One of these two types of conductive thread forms two sides that intersect at right angles, and the other also forms two sides that intersect at right angles. A potential difference occurs between the two metals. The interval is set so that the arm or the like can easily contact the two kinds of metals. If this grid is small, the contact area with the arm is large, but the price is high. On the other hand, if the mesh is too large, it is impossible to contact the two kinds of metals at the same time, no potential difference occurs between different kinds of metals, and functions such as health effects and antibacterial effects do not appear.
As a method of weaving the entangled yarn 1 and the copper fiber 5 into the cloth 4, there are methods such as hand-sewing and sewing.

In the above, an example is shown in consideration of the properties of each thread material and the sewing fabric using the material.
The number of aluminum foils 3 constituting the entangled yarn 1 shown in FIG. Further, a width of 0.2 to 0.3 mm which is the same as the diameter of the polyester core yarn 2 to be formed is appropriate. The entangled yarn 1 is formed while applying a squeezing step so that the flexibility of the polyester core yarn 2 can be followed.
FIG. 2 shows a sewing fabric 6 in which entangled yarns 1 and copper fibers 5 are arranged vertically and horizontally. If the distance between the squares is 10 to 20 mm, a potential difference between different metals can be generated in any part of the body such as arms, shoulders, legs, knees, and torso, and the health effect of eliminating pain such as stiff shoulders can be achieved. It can be expressed.

  The present invention is a fabric that contributes to health, such as relief of pain in each part of the body such as knees, arms, feet, and relief of stiff shoulders, such as towels, handkerchiefs, underwear, etc. Used for At the same time, since copper fiber has a deodorizing and antibacterial effect, it can be applied to clothes that deodorize nonenal which is the main component of aging odor.
