〔産業上の利用分野〕
本発明は、導電性シート、導電性床材、電磁波シールド

電性織布に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conductive woven fabric used for conductive sheets, conductive flooring materials, electromagnetic shielding materials, IC packaging materials, static electricity removal brushes, and the like.
導電性を有する織布、織布、不織布等の繊維製品として
はカーボン繊維、無電解メツキ繊維、金属蒸着繊維、硫
化銅結合繊維等の導電性繊維や金属細線を一部に用いる
ことで導電性を付与したものが知られている。Fiber products such as woven fabrics, woven fabrics, and non-woven fabrics that have conductivity can be made conductive by partially using conductive fibers or thin metal wires such as carbon fibers, electroless plating fibers, metal-deposited fibers, and copper sulfide bonded fibers. It is known that this has been given.
また近年、ポリピロール、ポリアニリン、ポリチオフェ
ン等は良好な導電性を示すことが見出され、これらのモ
ノマー及び酸化剤を含有する水溶液中に織布、不織布、
糸等を浸漬して酸化重合して繊維表面に直接析出せしめ
、織布等に導電性を付与することも提案されている。In addition, in recent years, it has been discovered that polypyrrole, polyaniline, polythiophene, etc. exhibit good conductivity, and woven fabrics, nonwoven fabrics,
It has also been proposed to impart electrical conductivity to woven fabrics by immersing threads or the like to undergo oxidative polymerization and depositing directly on the fiber surfaces.
しかし、これら繊維製品に用いられる金属細線やカーボ
ン繊維は屈曲疲労が発生し易く、無電解メツキ繊維や金
属蒸着繊維は繊維表面よりの金属脱落が著しいという欠
点が有ると共に、いずれも極めて高価なものであって、
しかもこれらを織布の経糸、緯糸の一部に織り込むこと
は繊維の熱収縮性や伸び、屈曲性等が著しく異なるため
に極めて整経及び製織しにくく、又、その繁雑さゆえに
製造上の問題もあり、広く一般的には使用されてはいな
かった。However, the fine metal wires and carbon fibers used in these textile products are prone to bending fatigue, and the electroless plated fibers and metal-deposited fibers have the drawback of significant metal shedding from the fiber surface, and are both extremely expensive. And,
Furthermore, weaving these into some of the warp and weft threads of a woven fabric is extremely difficult to warp and weave because the heat shrinkability, elongation, bendability, etc. of the fibers are significantly different, and the complexity causes manufacturing problems. However, it was not widely used.
また、ポリピロール、ポリアニリン、ポリチオフェン等
にて織布、編布、不織布の全面を導電化処理したものは
色相的に濃く、外観的にも劣るものであり、またカセ状
の糸をモノマー及び酸化剤含有水溶液中に浸漬して得た
導電性糸はモノマーの酸化重合反応が極めて速いもので
あるから全体に均質な導電性を有するものが得られ難く
、この糸を用いた織布は得られてはいなかった。In addition, woven fabrics, knitted fabrics, and non-woven fabrics whose entire surface is made conductive with polypyrrole, polyaniline, polythiophene, etc. have a dark hue and are inferior in appearance. The conductive thread obtained by immersing it in a containing aqueous solution undergoes an extremely rapid oxidative polymerization reaction of the monomer, so it is difficult to obtain one that has uniform conductivity throughout, and a woven fabric using this thread is difficult to obtain. There was no one there.
本発明者は、従来の導電性織布とその製造方法の欠点を
解決せんと鋭意研究した結果、部分的に異なる導電性を
有する導電性織布をピロール等の導電化処理にて安定し
た品質で容易に得られることを見出し本発明に至った。As a result of intensive research to resolve the shortcomings of conventional conductive woven fabrics and their manufacturing methods, the inventors of the present invention achieved stable quality by applying conductive treatment such as pyrrole to conductive woven fabrics having partially different conductivities. The present invention was based on the discovery that it can be easily obtained.
すなわち本発明は、アニリン、チオフェン、ピロール及
びこれらの誘導体の群から選ばれたモノマーを酸化重合

方法である。That is, the present invention provides a conductive woven fabric in which a conductive polymer formed by oxidative polymerization of a monomer selected from the group of aniline, thiophene, pyrrole, and their derivatives is deposited on at least the fiber surface. A conductive woven fabric characterized by being formed of at least two types of fibers having different adsorption properties for the monomer, and an aqueous solvent for a monomer selected from the group of aniline, thiophene, pyrrole, and derivatives thereof. A conductive woven fabric made of at least two types of fibers having different monomer adsorption properties is immersed in a solution, and then immersed in an aqueous solvent solution of a chemical oxidizing agent to precipitate a conductive polymer on the fiber surface. This is a manufacturing method.

It is oxidatively polymerized and precipitated by an oxidizing agent. The woven fabric can be immersed in each aqueous solution using a batch method, in which the woven fabric is immersed in a monomer aqueous solution bath under certain conditions, taken out, and then immersed in an oxidizing agent solution bath. It is also possible to use a continuous method of moving the . Alternatively, the woven fabric may be immersed in an oxidizing agent solution, then immersed in an oxidizing agent solution, and then further immersed in an oxidizing agent solution to oxidatively polymerize the monomer and precipitate a conductive polymer.
