Description

TECHNICAL FIELD The present invention relates to a woven fabric and a woven product using the same.

In recent years, adverse effects on the mind and body (headache, nausea, irritability, etc.) due to extremely low frequency electromagnetic waves generated from household electric appliances and the like have been regarded as a problem. For example, when an electromagnetic wave was measured for a person wearing a non-earthed personal computer wearing an electromagnetic wave prevention apron, it was reported that the electric field was about 150 V/m. It is reported in Non-Patent Document 1 below, for example, that many of them suffer from allergies such as severe stiff shoulders, headaches, blurred vision, hay fever, and rhinitis.

Furthermore, recently, in the laboratory of Associate Professor Takuya Tsujiuchi of the Faculty of Human Sciences, Waseda University, "Research on the effects of alternating electric fields on the body" has begun, and it is shown that the autonomic nervous system is affected by electromagnetic waves. Suggested experimental data are published by Non-Patent Documents 2 and 3 below.

Generally, an electromagnetic wave refers to a phenomenon in which an electric field and a magnetic field vibrate in directions perpendicular to each other and is propagated in a space or substance, or an oscillating electromagnetic field thereof, and a composite wave (electric field) of an electric field (electric field) and a magnetic field (electric field). And the wave of magnetic energy). Here, in this specification, an electric field and an electric field, and a magnetic field and a magnetic field are used in the same meaning, and an electric field (electric field) is a range affected by electricity, and a magnetic field (magnetic field) is influenced by magnetism. Means a range.

A magnetic field is generated when an electric current flows through an electric device or the like. Therefore, no magnetic field is generated when the power switch of an electric device or the like is turned off. On the other hand, an electric field is generated only when a voltage is applied. That is, even when the power switch of an electric device or the like is turned off, the electric field is generated only by inserting the plug into the outlet.

Therefore, in order to suppress the generation of an electric field and escape from the above-mentioned adverse effects on the mind and body due to the influence of electromagnetic waves, it is important to remove the power plug of the electric device from the outlet or ground the electric device. is there. Since the power plug cannot be unplugged from the outlet while the electric device or the like is being used, the most realistic and effective method for suppressing the influence of electromagnetic waves is to ground the electric device or the like. By grounding an electric device or the like, the potential of the electric device or the like can be lowered. Specifically, since the potential has a property of propagating from higher to lower, it is possible to make it difficult to propagate to a person in the vicinity by lowering the potential of an electric device or the like.

In order to reduce adverse effects on the mind and body due to extremely low frequency electromagnetic waves generated from the above-mentioned household electric devices, etc., each country has set guidelines for electromagnetic waves to call for suppressing electromagnetic waves generated from electric devices. In particular, the guidelines (TCO regulations) established by the Swedish Trade Union Association set the strictest standards in the world, and it can be seen that Sweden's interest in electromagnetic waves is high. On the other hand, in the guidelines established by the Japanese industry group, the criteria for magnetic fields are the same as the aforementioned Swedish guidelines, but the criteria for electric fields are 5 times at 100V and 25 times at 200V compared to the Swedish guidelines. Is allowed, and it clearly shows the delay in response and low interest.

Regarding the extremely low frequency electromagnetic wave generated from the electric device as described above, the present inventor has found that the side connected to the ground line inside the device such as the electric device is a cold line of a single-phase two-wire power supply line, that is, By connecting to a grounded power supply line, we succeeded in grounding electric equipment, that is, in the same state as grounding. A USB-compatible electric field eliminator that suppresses generation has been developed (see Patent Document 1 below).

As a result, by installing this device in electric equipment such as existing notebook computers and hot carpets, it is possible to suppress extremely low frequency electromagnetic waves generated from electric equipment to extremely low levels, and therefore it is widely used in various fields. It is expected (see Patent Document 2 below).

So far, the main cause of extremely low frequency electromagnetic waves in a house is that they are generated from electric devices inside the house, or that high-voltage transmission lines stretched over the house Various things were said, such as what is generated is the main factor, but it was not clear what was clear, and only measures were taken for individual sources. For example, Patent Documents 3 and 4 have been proposed as techniques for shielding electromagnetic waves from the outside of a house.

Further, the inventor of the present invention has acquired as a patent a method for constructing a house that suppresses the propagation of extremely low frequency electromagnetic waves in the house (see Patent Document 5 below).

By the way, static electricity is also likely to be generated in the dry season, and this static electricity can be charged to various things and discharged between the human body and cause an unpleasant tingling electrical stimulus to the human body. These can cause various problems in combination with the above problems.

The electrical stimulation caused by static electricity is not an exception even for towels and the like, and for example, Patent Document 6 below provides a technique relating to towels that generate little static electricity.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be embodied in many different forms, and is not limited to the exemplary descriptions of the embodiments and examples shown below.

FIG. 1 is a schematic diagram of a towel that is an example of a woven product (hereinafter also referred to as “this product”) using the woven fabric according to the present embodiment (hereinafter referred to as “the present woven fabric”), and FIG. FIG. 3 is a schematic view of this one section. In addition, FIG. 3 is an image diagram regarding the arrangement of the conductive fibers in the woven fabric 1.

This product uses this woven fabric at least in part, and is applicable to various products. This product is not limited to this, but in addition to towels, for example, underwear, underwear, towels, socks, hand towels, handkerchiefs, sheets, pillows, blankets, belly rolls, mufflers, hats, supporters, etc. You can

The present woven fabric 1 includes a large number of warp yarns 21, a large number of weft yarns 22 that are woven so as to intersect the large number of warp yarns 21, and a large number of pile yarns that are woven so as to intersect at least one of the large number of warp yarns 21 and the large number of weft yarns 22. 23, and at least a part of at least one of the plurality of warp yarns 21 and the plurality of weft yarns 22 is a conductive fiber 211, 221. In addition, in the example of the woven fabric 1, conductive fibers are woven in both the warp yarns and the weft yarns. Further, in the example of this figure, the fabrics of a large number of warp yarns 21 and a large number of weft yarns 22 are provided in two layers, and these are sewn together by a thread 222 for stitching.

As described above, the present woven fabric 1 is a combination of a large number of warp yarns and a large number of weft yarns, and is not limited as long as it can be provided as a product, but a towel or gauze provided with pile yarns, etc. Can be illustrated, but is not limited thereto. Further, the area (size) of the present woven fabric 1 can be appropriately set and is not particularly limited.

In the woven fabric material 1, the "conductive fiber" is a conductive material formed as a film around the basic fiber, and the "basic fiber" may retain the conductive material as a film. Examples of fibers that can be used as a base material include natural fibers and chemical fibers. When chemical fibers are used, acrylic fibers and nylon fibers can be preferably used, but not limited to these. In this case, the conductive substance formed as a film around the base fiber is preferably, but not limited to, digenite (Cu ₉ S ₅ ). Digenite is electrically conductive and can firmly coat the base fiber.

In the woven fabric 1, the conductive fibers 211 and 221 are woven in a large number of warp yarns and a large number of weft yarns with a width of 7 mm or more and 9 mm or less at a predetermined interval. By setting it in this range, it becomes possible to stably secure conductivity. In particular, in the case of the present fabric, as will be apparent from the examples described later, by setting it in this range, the property of letting out an AC electric field in combination with other warp yarns and weft yarns even if the user does not directly touch the conductive fiber is obtained. As well as being able to demonstrate, it becomes possible to discharge static electricity.

The distance between the widths of the conductive fibers is not limited as long as it has the above function, but is preferably in the range of 7 mm or more and 9 mm or less. By setting this range, it is possible to secure the range where the conductive fiber is not provided and to reduce the cost while maintaining the effect of this article.

In the woven fabric material 1, the warp yarns and the weft yarns may be single yarns or twin yarns, but are strong enough to secure the strength required for weaving with the conductive fibers to be woven. Is preferably maintained.

By the way, in general, the conductive fibers are thin basic fibers, and the coating around them is often thin, and in many cases it is not possible to secure sufficient strength. Further, when the conductive fiber is used as a single yarn, the conductive fiber becomes conspicuous if it is different in color from other warp yarns or weft yarns. Therefore, by twisting the conductive fiber with another single yarn (for example, cotton single yarn) to form a double yarn, the conductive fiber can be made as inconspicuous as possible and sufficient strength can be secured. In this case, it is preferable that the warp yarns or the weft yarns are single yarns or twin yarns having the same strength as the twin yarns containing the conductive fibers.

In the present woven fabric 1, the warp yarns and weft yarns between the conductive fibers, and the single yarns twisted with the conductive fibers are not limited, but at least natural fibers, specifically cotton and hemp. Either is preferable, and animal fibers such as wool may be used. These are common materials, and even if a special material is not used as in the above-mentioned known technique, the entire cloth can release an AC electric field and obtain an effect of preventing static electricity.

In the woven fabric material 1, the pile yarn height is preferably in the range of 2 mm or more and 4 mm or less. Here, the "height" of the pile yarn means a length from one warp yarn or one weft yarn of the woven pile yarn to the folded portion (one warp yarn or one warp yarn or one weft yarn woven next from one warp yarn or one weft yarn). Half of the length up to one weft thread), which means the length of the portion shown in FIG. 3, for example. In the present woven fabric 1, by setting the pile length to 2 mm or more, the warp yarns and the weft yarns can be sufficiently covered, and the contact area between the metal contained in the conductive fibers and the human body can be sufficiently suppressed. Become.

Regarding the pile yarn, as described above, it is possible to suppress the tint caused by the conductive fibers appearing on the surface and to prevent the metal from directly touching the human body, but not providing it. Even in the case, the performance can be sufficiently maintained.

Further, in the present woven fabric 1, the fabric has a double structure, one of which is a woven fabric in which warp threads and weft threads are woven without using conductive fibers, specifically a gauze cloth, and the other. Is a towel cloth in which conductive fibers are woven and pile yarns are also woven. By doing so, one side is not woven with conductive fibers and does not come into direct contact with the skin. On the other hand, as will be described later, since the pile yarn is woven, even if the conductive fiber is woven, it is hard to touch the skin, and contact with a metal or the like can be suppressed as much as possible. The gauze cloth and the towel cloth can be integrated by weaving so that a part of the weft thread or the warp thread is intertwined with each other. Of course, it is preferable that the woven fabric 1 of the present invention has a double structure. However, from the viewpoint of being able to obtain the effects of the present invention, it is of course possible to have a single structure.

As described above, according to the present invention, it is possible to provide a woven fabric that can release an AC electric field and prevent electrostatic charge without using a large amount of a special material. Specifically, this woven fabric is provided with pile yarns by weaving a large number of warp yarns and a large number of weft yarns with conductive fibers, thereby suppressing the area where a person touches the metal in the conductive fibers while ensuring conductivity. be able to. In addition, this woven fabric can exhibit sufficient electrostatic characteristics simply by weaving conductive fibers, can be used for fabrics that use commonly used general chemical fibers, and can suppress price increases. ..

Here, a woven fabric was actually produced and its effect was confirmed. This will be specifically described below.

(Dough 1)
First, using cotton having a thickness of 30th single yarn and conductive fiber having a thickness of 40th single yarn (Sanderron (registered trademark) manufactured by Japan Silkworm Dyeing Co., Ltd.) on each of the warp side and the weft side, While weaving conductive fibers with a width of 8 mm, weaving them in a grid pattern at intervals of 8 mm, and further weaving pile yarns with a pile length of 3.5 mm to make a towel cloth. And a towel of gauze cloth and double cloth in which weft was woven was prepared. The area of this cloth was 140 cm×200 cm. A photograph of the produced towel is shown in FIG.

Then, the effect of suppressing the electric field was confirmed for this woven fabric. Specifically, this towel is placed on two 100V household indoor wirings, connected to a ground device, and then the electric field value (A) on it and the electric field value at a position 30 cm away from it ( B) was measured by measuring each. An image diagram in this case is shown in FIG. This measurement was performed using an electric field measuring instrument Fauser Field Meter FM6. As a result, in this towel with conductive fibers of 8 mm width arranged at intervals of 8 mm, 30 V/m was observed in (A) and 3 V/m in (B), which is considered to be the most severe in Sweden. It was confirmed that the value could be suppressed to about the MPR-II regulation numerical value of. On the other hand, it was 590 V/m in (A) and 150 V/m in (B) when no towel was placed. Further, the same measurement was performed using a towel having the same structure except that the conductive fiber was not woven, but the result was the same as when nothing was present.

Further, this towel was placed on a hot carpet for household use, and the effect of suppressing the electric field was confirmed in the same manner as above. An image of the arrangement position on the hot carpet is shown in FIG.

As a result, as shown in Table 1 below, it was confirmed that the electric field could be sufficiently suppressed. Similar to the above, in the state where the present towel was not arranged, as shown in Table 1 below, sufficient electric field suppression could not be performed. Further, the same measurement was performed using a towel having the same structure except that the conductive fiber was not woven, but the result was the same as when nothing was present.

On the other hand, the same measurement as above was performed on a towel having the same structure except that the width of the conductive fibers and the distance between the conductive fibers were changed. The results are shown in Table 2 below. According to this result, it was confirmed that the width of the conductive fibers could be preferably 7 mm or more, while the distance between the conductive fibers was also preferably 9 mm or less. On the other hand, by setting the width of the conductive fiber to be equal to or less than the width of the conductive fiber, the amount of the conductive fiber can be reduced to ¼ or less in one sheet of fabric, and the cost can be reduced.

As described above, the effect of the present invention can be confirmed by the present example and the comparative example.
