Description

【０００１】
【発明の属する技術分野】
本発明は、例えばホテルや病院や事務所等の室内を歩行中に、人体に帯電する静電気により電撃等の不快感が生じるのを防止する技術に関する。
【０００２】
【従来の技術】
従来、例えばスリッパ等の履物を履いた人がホテルや病院や事務所等の室内を歩行すると、床面と履物底との摩擦によって床と履物の双方に静電気が発生して帯電し、その履物を履いた人間も静電気からの誘導によって帯電する。このような人体への帯電は、例えば抵抗値の低い金属等の導体に接触した際に、電撃（火花放電）等の不快感を生じさせるため、例えば金属等と手の間に、電気抵抗値が１０^６〜１０^１１Ω程度の抵抗の大きい静電気拡散部材を配置して、電撃の防止を図ったり、加湿器や散水の使用により環境湿度を６０〜６５％以上に上げ、静電気を拡散しやすくして、人体への帯電を抑制したり、特開平６−３３５４０１号のような導電性スリッパを導電性床上で使用して、人体に帯電した静電気を床から拡散させるような技術が知られている。
【０００３】
【発明が解決しようとする課題】
ところが、金属等と手の間に抵抗の大きい静電気拡散部材を配置するような技術は、機能上配置が不可能な場合があったり、美観上適切でない場合がある。
また、加湿器や散水によって湿度を上げる方法は、適用空間部が広すぎたり、散水が出来ない場所であったりすると効果が少ないか、または効果が得られず、また導電性床を使用する技術は、床材が高価なため、設備費がかかる等の問題がある。
また、導電性素材からなる導電性スリッパ等の履物と、導電性床材との両方を組み合わせて使用することは、一般の住宅やホテル等では行うことが難しく、また、いずれか一方だけを使用するのでは、効果の面で充分でなかった。
【０００４】
そこで本発明は、一般的に使用されている絶縁性の床を使用したフロアでも、履物を通して静電気が拡散されて人体に帯電しにくいようにし、電撃による不快感を防止するとともに、一般の履物でも簡易に静電防止効果が得られる静電防止材を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するため本発明は、履物の底に静電防止材を設けた履物であって、前記静電防止材は、起毛のある導電性不織布であり、且つ前記起毛の繊維径が数μｍ〜数十μｍであり、前記起毛のある導電性不織布は、接地面側に起毛が存在するように設けられるようにした。

【０００６】
すなわち、履物を履いた人が床を歩行すると、床と履物の摩擦により、床と履物の両者にお互いに逆極性の静電気が発生する。ここで床が絶縁性であれば、履物が絶縁性の場合は勿論、履物が導電性であっても静電気が人体に帯電し、床が導電性であれば、履物が絶縁性の場合に静電気は人体に帯電する。
この場合、人体への帯電電位が２ｋＶ以下の場合は、抵抗値の低い金属等の導体に触れても殆ど電撃を感じないが、２〜３ｋＶ以上になると電撃を感じて不快な思いをすることが多くなる。
【０００７】
このような絶縁物に帯電する静電気を効果的に除去するには、帯電電荷と逆極性のイオンにより中和することであり、静電気の中和に利用されるイオンの発生方法としてはコロナ放電による方法が一般的である。
このコロナ放電は、先の尖った針電極や、細線電極や、曲率半径が極めて小さい電極の近傍に不平等電界が形成され、その電界が局部的に絶縁破壊電界強度を超えることによって起きる放電であり、導電性繊維の起毛はコロナ放電を生じさせるのに最適である。
このため、履物用の静電防止材として、歩行によって床と履物との間に生じる静電気を導電性繊維の起毛のコロナ放電作用によって、電撃を感じない程度まで緩和出来るようにする。
【０００８】
すなわち、本発明の静電防止材を、一般の導電性を有さないスリッパや、サンダルや、カジュアルシューズや、スポーツシューズ等の履物底に対して、接地面側に起毛が存在するように、起毛のある導電性不織布を両面テープや接着剤や縫製等の手段によって固定すれば良い。
または、本静電防止材の、起毛のある導電性不織布を基材としたレザーや人口皮革等のスリッパ等を作製し、少なくとも靴底部分は、基材となる起毛のある導電性不織布における起毛が接地面側に出るようにすれば良い。
この際、起毛のある導電性不織布としては、ステンレス繊維などの金属繊維や、カーボン繊維や、合成樹脂繊維を導電化した導電性繊維が使用出来、これら導電性繊維を交絡した導電性不織布の起毛のあるものが適用でき、特に、多数の針状の起毛が不織布の表面に存在するものが好ましい。
【０００９】
更に本発明では、前記起毛の繊維径が、数μｍ〜数十μｍであるようにした。ここで、コロナ放電は、電荷が集中する電極先端の曲率に依存し、曲率が小さいほど発生しやすい。このため、起毛の繊維径は数μｍ〜数十μｍとした。

【００１１】
ここで、本発明の静電防止材は、前述のように、起毛のある導電性不織布を、接地面側に起毛が存在するように導電性のない一般の履物の履物底に接着または縫着するようにしても良く、また、基材の周囲に合成皮革や合成樹脂レザー等の被覆材を被せたような履物において、基材を起毛のある導電性不織布とし、履物の接地面側の被覆材を開放して接地面側の基材となる起毛のある導電性不織布における起毛を露出させるようにしても良く、また、履物底自体を起毛のある導電性不織布で構成し、起毛を接地面側に存在させるようにしても良い。
【００１２】
【発明の実施の形態】
本発明の実施の形態について添付した図面に基づき説明する。
ここで図１は本発明に係る履物用の静電防止材を接地面側から見た説明図、図２は図１のＡ−Ａ線拡大断面図、図３は同静電防止材を履物の接地面側に貼り付けた状態の説明図、図４は本発明に係る静電防止手段を採用した履物の一例を示す説明図、図５は各種履物を使用して歩行し、人体に帯電した電位測定を比較した試験結果図である。
【００１３】
本発明に係る履物用の静電防止材及び履物は、例えばホテルや病院や事務所等の一般の床面を歩いた時でも、人体に帯電する静電気が抑制されて電撃等の不快感を防止出来るようにされ、安価に且つ簡易な構成で達成出来るようにされている。
【００１４】
まず静電防止材の構成から説明すると、この静電防止材１は、図１、図２に示すように、靴やスリッパやサンダル等の履物の接地面側に貼り付け可能とされ、導電性繊維からなる導電性不織布２の裏面側に両面テープの接着層３が設けられ、その上に離型紙４が付着されており、導電性不織布２の底面側には起毛部２ａが形成されている。
【００１５】
そして、図３に示すように、離型紙４を剥がして接着層３を履物５の接地面側に貼り付ければ、起毛部２ａが床面に接触するようにしており、本実施例では、導電性不織布２として、表面側に多数の突起状の起毛部２ａが形成されるアキレス株式会社製のＳＴ不織布（商品名）としている。
【００１６】
ここで、前述のように、導電性繊維としては、金属繊維やカーボン繊維の他、ポリエステル系、ポリアミド系、ポリアクリル系、ポリオレフィン系、ポリウレタン系等の合成樹脂繊維を導電化したものが使用可能であり、合成樹脂繊維を導電化する方法としては、ポリピロールやポリアニリン等の導電性ポリマーを繊維表面及び／又は繊維内部に複合化する方法や、硫化銅を繊維表面に被覆する方法等、一般に繊維の導電化に使用されている任意の技術が適用可能である。
【００１７】
また、導電化する前の合成樹脂繊維を交絡して得られる不織布を導電化するようにしても良い。
【００１８】
また、静電防止材１を履物５の底に貼り付ける手段は、両面テープの接着層３に限られるものではなく、通常の接着剤によるようにしても良く、また縫い付けるようにしても良く、特に限定されるものではない。

因みに、このような静電防止材１は、ホテル等において使い捨て方式にすることも可能である。
【００２０】

そしていずれの場合も、接地面側に起毛部が形成されており、前記静電防止材１と同様な静電防止効果が得られるようにしている。
【００２１】

BACKGROUND OF THE INVENTION
The present invention relates to a technique for preventing unpleasant feeling such as electric shock caused by static electricity charged on a human body while walking in a room of a hotel, hospital, office, or the like.
[0002]
[Prior art]
Conventionally, when a person wearing footwear such as slippers walks in a room such as a hotel, hospital or office, static electricity is generated on both the floor and the footwear due to friction between the floor surface and the footwear bottom, and the footwear is charged. The person who wears is charged by induction from static electricity. Such charging of the human body may cause discomfort such as electric shock (spark discharge) when contacting a conductor such as a metal having a low resistance value. However, it is easy to disperse static electricity by disposing a static-resistant diffusion member with a large resistance of about 10 ⁶ to 10 ¹¹ Ω to prevent electric shock or using a humidifier or watering to raise the environmental humidity to 60 to 65% or more. In addition, there is known a technique for suppressing charging of the human body or diffusing static electricity charged on the human body from the floor by using a conductive slipper such as JP-A-6-335401 on the conductive floor. Yes.
[0003]
[Problems to be solved by the invention]
However, the technique of disposing an electrostatic diffusion member having high resistance between a metal or the like and a hand may not be functionally disposed or may not be aesthetically appropriate.
In addition, the method of increasing the humidity by using a humidifier or watering is not effective or is not effective if the application space is too wide or watering is not possible, and the technology uses conductive floors. However, since the flooring is expensive, there are problems such as high equipment costs.
In addition, it is difficult to use both footwear such as conductive slippers made of conductive material and conductive flooring in general houses and hotels, and use only one of them. However, the effect was not sufficient.
[0004]
Therefore, the present invention makes it difficult for static electricity to diffuse through footwear and prevent the human body from being charged easily even in a floor using an insulating floor that is generally used, and prevents discomfort due to electric shock. It aims at providing the antistatic material from which the antistatic effect is acquired easily.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a footwear in which an antistatic material is provided on the bottom of the footwear, wherein the antistatic material is a conductive non-woven fabric with napping, and a fiber diameter of the napping is several. The conductive non-woven fabric having a raised surface that is μm to several tens of μm is provided so that the raised surface exists on the ground surface side.

[0006]
That is, when a person wearing footwear walks on the floor, static electricity having opposite polarities is generated on both the floor and the footwear due to friction between the floor and the footwear. If the floor is insulative, the footwear is insulative, and even if the footwear is conductive, static electricity is charged to the human body. If the floor is conductive, the footwear is insulative. Is charged to the human body.
In this case, when the charged potential to the human body is 2 kV or less, even if it touches a conductor such as a metal having a low resistance value, almost no electric shock is felt. Will increase.
[0007]
In order to effectively remove the static electricity charged in such an insulator, neutralization is performed with ions having a polarity opposite to that of the charged electric charge. As a method of generating ions used for neutralization of static electricity, corona discharge is used. The method is common.
This corona discharge is a discharge that occurs when an unequal electric field is formed in the vicinity of a sharp needle electrode, a thin wire electrode, or an electrode with a very small radius of curvature, and the electric field locally exceeds the breakdown field strength. Yes, the raising of the conductive fibers is optimal for causing corona discharge.
For this reason, as an antistatic material for footwear, the static electricity generated between the floor and the footwear by walking can be mitigated to the extent that no electric shock is felt by the corona discharge action of the raised conductive fibers.
[0008]
In other words, the antistatic material of the present invention is such that there are raised brushes on the grounding surface side with respect to footwear such as slippers, sandals, casual shoes, sports shoes, etc. that do not have general conductivity. What is necessary is just to fix the electrically conductive nonwoven fabric with raising by means, such as a double-sided tape, an adhesive agent, and sewing.
Alternatively, a slipper such as leather or artificial leather made of the antistatic material with a raised conductive nonwoven fabric as a base material is produced, and at least the shoe sole portion is raised in the conductive nonwoven fabric with the raised base material. Should be on the ground side.
At this time, as the conductive nonwoven fabric with raised hairs, metal fibers such as stainless fibers, carbon fibers, and conductive fibers made of synthetic resin fibers can be used, and the conductive nonwoven fabric raised by entanglement of these conductive fibers can be used. of certain things can be applied, particularly preferably one in which a large number of needle-like napped present on the surface of the nonwoven fabric.
[0009]
Furthermore, in the present invention, the raised fiber has a fiber diameter of several μm to several tens of μm. Here, the corona discharge depends on the curvature of the electrode tip where the charge is concentrated, and the corona discharge is more likely to occur as the curvature is smaller. Therefore, the fiber diameter of brushed was several μm~ several tens [mu] m.

[0011]
Here, as described above, the antistatic material of the present invention adheres or sews a conductive non-woven fabric with brushing to a footwear bottom of ordinary footwear that is not conductive so that there is brushing on the ground surface side. In addition, in footwear in which a base material is covered with a covering material such as synthetic leather or synthetic resin leather, the base material is made of a conductive non-woven fabric with brushed, and the grounding surface side of the footwear is covered. may be made to expose the brushed in the conductive nonwoven fabric by opening the timber a brushed as a base material of the ground surface, also the shoe sole itself is made of a conductive nonwoven fabric with a brushed, ground surface brushed You may make it exist in the side.
[0012]

FIG. 4 is an explanatory view showing an example of footwear adopting the antistatic means according to the present invention, and FIG. 5 is a case where a person walks using various footwear and charges the human body. It is the test result figure which compared the measured electric potential.
[0013]
The antistatic material for footwear and footwear according to the present invention prevents discomfort such as electric shock by suppressing static electricity charged to the human body even when walking on a general floor surface such as a hotel, hospital or office. It can be achieved at low cost and with a simple configuration.
[0014]
First, the structure of the antistatic material will be described. As shown in FIGS. 1 and 2, the antistatic material 1 can be attached to the grounding surface side of footwear such as shoes, slippers, and sandals.

[0015]
As shown in FIG. 3, when the release paper 4 is peeled off and the adhesive layer 3 is attached to the grounding surface side of the footwear 5, the raised portions 2a are brought into contact with the floor surface. The non-woven fabric 2 is an ST nonwoven fabric (trade name) manufactured by Achilles Co., Ltd. in which a number of protruding raised portions 2a are formed on the surface side.
[0016]
Here, as described above, as the conductive fibers, in addition to metal fibers and carbon fibers, polyester, polyamide, polyacrylic, polyolefin, polyurethane, and other synthetic resin fibers can be used. As a method of making synthetic resin fibers conductive, generally, fibers such as a method in which a conductive polymer such as polypyrrole or polyaniline is compounded on the fiber surface and / or inside the fiber, or a method in which copper sulfide is coated on the fiber surface are used. Any technique that is used for the electrical conduction of can be applied.
[0017]
Moreover, you may make it electrically conductive the nonwoven fabric obtained by entanglement with the synthetic resin fiber before electrically conducting.

This is an example in which the covering material 10 on the ground surface side is opened to expose the base material 9 in the same part.
In either case, a raised portion is formed on the ground surface side so that the same antistatic effect as that of the antistatic material 1 can be obtained.
