Description
The present invention is chiefly directed to the footwear with anti-belts electrical conductivity characteristic that use in the operating environment of being afraid of static, it is Electically conductive shoes, for example, make with in the clean room at large scale integrated circuit (LSI), perhaps the footwear that in using the places such as oil, gasoline and organic solvent of managing inflammability, explosion hazard, use with anti-belts electrical conductivity characteristic.
In recent years, a lot of dress materials and footwear are high megohmite insulants, owing to use materials such as synthetic resin, synthetic fibers and synthetic rubber, produce static naturally when wearing.
Therefore, making or using in the environment of electronic instrument of LSI (large scale integrated circuit) or super LSI etc., for the LSI that prevents to cause, the damage of super LSI by static, in addition, in order not make, be necessary to take suitable anti-charged measure because of static is brought in the operating environment attached to the dust on the clothes.In addition, cause danger such as fire and blast owing in the environment of the material that uses inflammabilities such as oil, gasoline and organic solvent, explosion hazard, exist, so be necessary to take anti-charged measure because of static.
Being not only the environment that must strictly get rid of static as described above, is exactly air dried the time, and the spark of generation of static electricity also often makes the people feel under the weather.
In order to solve relevant issues, prevented for making sole have electric conductivity that the footwear of human body static electrification from having carried out various research and development in the past.
As making sole have the method for electric conductivity, the handlebar additive adds the method for making Electically conductive shoes in the resin itself that constitutes sole.
For example, open the scheme that proposes in the clear 59-62003 communique and be real public clear 59-32324 number, real fair 2-28721 number, spy, constitute Electically conductive shoes by the sole of the polyvinyl chloride resin complex injection mo(u)lding of using the cation system, nonionic system, anion system or the various interfacial agents of both sexes or their articles for use etc. that add as charged preventor.In these documents,, resin complex that mixes carbon black and the resin that in polyurethane, has added charged preventor (real public clear 59-32324 number, real fair 2-28721 number) have also been spoken of in addition as the material at the bottom of this Electically conductive shoes.
In addition, open in the 2000-14404 communique the spy, introduced heat foamable sclerosis using with respect to 100 weight portions by specific ethylene-vinyl acetate base copolymer, the component of polymer of any formation of the component of polymer that perhaps specific ethylene-vinyl acetate base copolymer and acrylonitrile butadiene rubber are formed, charged preventor (for example, the quaternary ammonium salt that contains 1～10 weight portion, the cation of stearoyl amido propyl-dimethyl-β hydroxyethyl ammonium nitrate etc. is an activating agent, anion system or nonionic are activating agent, the amphoteric surfactant slaine, polyol derivative, alkylamine derivative etc.), blowing agent, the mixture of crosslinking agent obtains prevents charged material for sole of shoe.
But, additive adding sole resin itself is being produced in the method for electric conductivity, because exist that the moulding that produces because of the addition of additive is bad, inappropriate situation such as bonding bad of member, so be necessary to consider relation with rerum naturas such as the mouldability of material, cementabilities.In addition, in these methods, because the additive of charged preventor etc. is added in the middle of the major part of sole as other material, so improved the cost of material itself.
The method that in material for sole of shoe, adds additive in this wise, owing to changed the rerum natura of material, consider from performance (resiliency after mouldability, the making etc.) aspect of its requirement, on its addition, be limited, in addition, for sole, because the thickness more than needing necessarily on its performance, so it is also limited that the thickness by the attenuate sole suppresses the method for charged preventor.Owing to these reasons, also repeatedly discussed by the method that other approach makes sole have the electric conductivity part.
Open in the clear 63-46101 communique the spy, the structure that proposes is, added the preventing in the static electrification footwear of polyamine fat sole of the polyamine fat resin of the additive (the metal fine powder charged preventor that carbon black or quaternary ammonium salt are such) that improves electric conductivity in use, be set up in parallel two plate electrodes up and down, one of them electrodes on the interior end, another electrode is imbedded inside at the bottom of the Electically conductive shoes, this two plate electrode is coupled together or connect with same electrode with conductive material.Because electrode is set up in parallel up and down on two of sole, so has in fact shortened at the interval below electrode and the sole, its result guarantees the electric conductivity between pin electrodes in contact part and the sole surface easily.Therefore, although very high,,, also can provide footwear with sufficiently high electric conductivity even if sole is thick sole also without the thickness of attenuate sole with sacrifice wearing comfortableness as the resistance value of the polyamine fat resin of material for sole of shoe.But, because inside at the bottom of textural plate electrode is in Electically conductive shoes, can not be corresponding with the manufacture method of habitual injection mo(u)lding sole, so that Sole moulding becomes is very miscellaneous, in addition, can not be with sole pattern diversified corresponding.
Have again, the charged footwear that prevent that the spy opens the proposition of 2000-102401 communique are, the interior end top and below have contact-making surface and wire that the conductive filament sewing forms be set to banded elongated conductive part, the interior end contact this elongated conductive part above, the middle end contact above-mentioned elongated conductive part below, above-mentioned in the end and centre at the end respectively setting contact with the part of above-mentioned elongated conductive part and become the contact portion of contact.And the contact portion at the interior end constitutes with conductive filament sewing, the member of the die-cut portion that the contact portion at the middle end is formed by the member (for example EVA foaming body) at the end in the middle of constituting with the conductive fabric winding is die-cut or the monomer material formation of electric conductivity.These charged footwear that prevent even if its middle end is to be made of the EVA that does not have electric conductivity, owing to have contact portion, also are the soles that electric conductivity can be provided.But, this contact portion is after die-cut member, again winding the die-cut portion of conductive fabric insert once more in this hole punching, perhaps insert the different member of electric conductivity, so manufacturing process is very miscellaneous, in addition, because the part at the end is not an one with the middle end in the middle of die-cut, so the sole that is in contact with it has uncomfortable sensation.In addition, owing to use die-cut method on the middle end,, can not provide too big conductive region with respect to the centre surface area at the end.
In addition, have the Electically conductive shoes that so-called grounding construction is arranged from the sole to the ground plane for the conductive member that metal for example etc. is set at material for sole of shoe with at middle the end, proposed very many motions.But these motions all have in the time of can not obtaining sufficient conductive effect, complex structure or wear footwear shortcomings such as foot sense of touch difference.
Purpose of the present invention is exactly in order to solve with the indeterminable problem of above-mentioned prior art, a kind of thickness and shape that does not limit sole is provided, do not influence sufficient sense of touch etc. snugness of fit, can easily adjust the Electically conductive shoes of the electric conductivity of sole.
The objective of the invention is in addition, provide a kind of by the simpler method of complicated procedures of forming is not set on making, use the good footwear of the original resiliency that always uses with non-conductive material (generally being EVA), do not add the Electically conductive shoes that additive such as charged preventor just can be made.
In order to achieve the above object, present inventors have carried out conscientiously research.Found that, can provide to have the simpler method of on the middle end that the footwear such as EVA good by common resiliency constitute with non-conducting material, using than prior art of method the conduction road is set, make from the interior end of the conduction processing of the upside at the middle end to the Electically conductive shoes that has the sole structure of electric conductivity the footwear outer bottom with electric conductivity of the downside at the middle end.
