アースする方法(アース法)
静電防止剤を加工品に付着させる方法(総加工法)
吸湿性のある物質で被膜する方法(加湿方法)
除電ブロアーで反対イオンを吹きつける方法(ブロアー法)
しかし これらの方法は要求がすべて満たされないものであり、実用上不充分であった。
In order to prevent the above-described static electricity failure, it is necessary to quickly reduce the amount of generated static electricity so that static electricity does not accumulate. The following method has been adopted as a specific method for preventing static electricity.
Grounding method (grounding method)
Method to attach antistatic agent to processed products (total processing method)
Method of coating with hygroscopic substance (humidification method)

However, these methods do not satisfy all the requirements and are insufficient in practical use.

本発明の目的は物体の生産活動時や人体の日常動作において、物体や人体の静電気帯電を中和して、帯電量を減少させ、生産の効率アップ、作業環境の改善を人体の疲労、筋肉痛、こむらかえりなどの症状を軽減させるため、放電組紐、放電布帛などの静電気帯電中和材料を提供する事にある。   The object of the present invention is to neutralize the electrostatic charge of an object or human body during production activities of the object or in the daily operation of the human body, thereby reducing the amount of charge, increasing the production efficiency, and improving the work environment. An object of the present invention is to provide an electrostatic charge neutralizing material such as a discharge braid and a discharge cloth in order to alleviate symptoms such as pain and swaying.

上記の本発明の目的は、物体・人体の静電気帯電を中和させるために物体・人体に接触する組紐・布帛の中に炭素繊維の短繊維からなる静電気中和芯材を構成してなる各種用具を提供する事にある。また、これらの用具は電源が不要で、物体・人体の必要部分に接触、非接触で取り付ける事により目的が達成されるのである。   The above-mentioned object of the present invention is to provide various types of electrostatic neutralizing cores composed of short carbon fiber fibers in braids and fabrics that come into contact with the object / human body in order to neutralize the electrostatic charge of the object / human body.

A cloth coated with the surface of an unemployed cloth after being mixed with a binder made of a conductive acrylic resin or the like. Thereby, the static electricity neutralization core material is comprised.

炭素素繊維又は合成繊維に金属メッキした繊維の短繊維は短繊維繊度が0.5〜3デニール、長さが1〜12mmのものが適用できる。
この炭素繊維又は合成繊維に金属メッキした繊維の短繊維はパルプを混合して混抄紙を作り。テープにするかまたは、バインダーに混合して、布帛表面にコーテングすることにより静電気中和芯材とすることが出来る。
この混抄紙やコーテングした静電気中和芯材は、炭素繊維又は合成繊維に金属メッキした繊維の短繊維が布帛表面から、突出しており、この突出により物体や人体の静電気と反対イオンを大気中から集めて中和させるようにしたものである。
The short fibers of the carbon fibers or the metal fibers plated on the synthetic fibers may be those having a short fiber fineness of 0.5 to 3 denier and a length of 1 to 12 mm.
This carbon fiber or synthetic fiber short metal fiber is mixed with pulp to make a mixed paper. A static neutralizing core material can be obtained by forming a tape or mixing it with a binder and coating the surface of the fabric.
In this mixed paper or coated electrostatic neutralizing core material, short fibers of carbon fibers or metal fibers plated on synthetic fibers protrude from the fabric surface, and this protrusion causes ions opposite to the static electricity of the object or human body to come out from the atmosphere. They are collected and neutralized.

本発明においては、上記静電気中和芯材を組紐の中心部、又は織物や不織布の層間に配置させる事から、芯材の炭素繊維や合成繊維に金属メッキした繊維の微細なホコリが出ない。したがって,IT関係、精密機械、高級印刷などの工程の静電気中和、防止の材料や、包装材料を作ることが出来る。   In the present invention, since the above-mentioned electrostatic neutralizing core material is disposed in the center portion of the braid or between the layers of the woven fabric and the non-woven fabric, the fine dust of the metal-plated carbon fiber or synthetic fiber in the core material does not appear. Therefore, it is possible to produce static neutralization and prevention materials and packaging materials for processes such as IT, precision machinery, and high-grade printing.

この芯材は組紐や二重布帛の中心部に存在し、表面からは見えないが、通気性があり
表層の素材を通して、静電気中和の効果がある。
This core material is present at the center of the braid or double fabric and is not visible from the surface, but is breathable and has an effect of neutralizing static electricity through the surface material.

また、本発明における芯材の組紐用は混式抄紙法によって作った紙をスリットしたテープであり、炭素繊維や金属メッキを施した短繊維は安定して集束している。
布帛用は水溶性アクリル系樹脂などからなるバインダーでコーテング、熱処理したもので、水に浸けても安定している。

図1、図2において、1はポリプロピレン組紐の外層フイラメントヤーン、2は炭素繊維または金属繊維の表面に金属メッキを施した短繊維5〜40重量%を紙に抄込んで目付30〜100g/mの混抄紙テープであり、炭素繊維の先端が芯材の表面に突出している。
3は炭素繊維又は金属繊維の表面に金属メッキを施した繊維の短繊維がバインダーに混合されてコーテング短繊維等の混合樹脂層であり、その先端が突出している。

本発明においては、芯材2.3、の表面から炭素繊維又は合成繊維に金属メッキした繊維の短繊維の一端または両端が突出しているため、仮に帯電した物体、人体がこの紐または布帛に接近し10mm以内の非接触でも、接触でも帯電体の静電気は中和して帯電が無くなる。芯材にある静電気中和材の炭素繊維又は合成繊維に金属メッキした繊維の1本毎の突出した一端又は両端が、アンテナの役目を果しており、物体、人体の帯電イオン(+と仮定する)と反対のイオン(−イオン)が大気イオンの中から集って中和して帯電を除去する物理作用として働く。大気イオンは大気中に浮遊している帯電微粒子を総称しているものであるが、ここで物体、人体が+に帯電していると仮定すると大気中の−イオンが、放電材料の、紐、布帛の静電気中和材に含まれる炭素繊維又は金属メッキした繊維の先端に集って、イオン平衡になる。すなわち中和するのである。   In the present invention, since one end or both ends of the short fiber of the fiber plated with carbon fiber or synthetic fiber is projected from the surface of the core material 2.3, a temporarily charged object or human body approaches this string or fabric. However, even if it is non-contact within 10 mm or contact, the static electricity of the charged body is neutralized to eliminate the charge. The protruding one or both ends of each of the carbon neutralized carbon fiber or synthetic fiber metal-plated fibers in the core material serve as antennas, and charged ions of objects and human bodies (assuming +) The ions (-ions) opposite to the negative ions collect from the atmospheric ions and neutralize to act as a physical action to remove the charge. Atmospheric ions are a collective term for charged fine particles floating in the atmosphere. Here, assuming that an object or a human body is charged to +, the − ions in the air are The carbon fibers or the metal-plated fibers contained in the cloth's electrostatic neutralizing material gather at the tips of the fibers to reach ionic equilibrium. That is, it is neutralized.

上記の繊維炭素繊維又は合成繊維に金属メッキしたの太さは出来るだけ細い方が良く、また繊維長は出来るだけ長い方が良い。イオンを集めやすいためである。具体的には繊度が0.5〜3デニール、長さが1〜15mmのものが好ましい。
炭素繊維又は合成繊維に金属メッキした金属繊維の静電気中和の除電効果については三者略同程度である。
試験条件はポリエステルフイルムを2、4、8、10KVに帯電させて35m/min
で走行させ、測定電極とフイルムの間隔を2mm、室温20℃湿度35%の時の残留電荷は次の通りである。
The thickness of the above-described carbon fiber or synthetic fiber plated with metal is preferably as thin as possible, and the fiber length is preferably as long as possible. This is because it is easy to collect ions. Specifically, a fineness of 0.5 to 3 denier and a length of 1 to 15 mm are preferable.
About the static elimination effect of the static electricity neutralization of the metal fiber which plated the carbon fiber or the synthetic fiber with metal, it is substantially the same as the three.

炭素繊維は金属繊維又は金属メッキ繊維と比較し、静電気中和能力、性能は同程度であるが、錆びない、軽量、(比重は金属繊維の1/4)、安価(コスト1/2以下)、金属繊維より加工性は良好である。
金属繊維の短繊維を合成繊維と混紡して紐にした商品も市場に出ているが、紡績糸は微細なホコリの発生があり、フイルム工程、精密機械,IT機器などへの使用には適合しない。
本発明は表面が合成繊維のフイラメントヤーンで覆はれており、微細なホコリがでないのも特徴である。
Compared to metal fiber or metal-plated fiber, carbon fiber has the same level of static electricity neutralization capability and performance, but does not rust, is lightweight (specific gravity is 1/4 that of metal fiber), and is inexpensive (cost is less than 1/2). The processability is better than that of metal fibers.
There are products on the market that are made by blending short fibers of metal fibers with synthetic fibers, but spun yarns generate fine dust and are suitable for use in film processes, precision machinery, IT equipment, etc. do not do.
The present invention is also characterized in that the surface is covered with a synthetic fiber filament yarn and there is no fine dust.
