To solve the problems caused by static electricity, can use the following two methods:

(a) the preventing static electricity (electric)

(two) the static reducing or lead to the accumulation of.

For the first method, the mechanism of electrostatic generationin do not understand, is made to a synthetic fiber does not generate static electricity in the friction and contact process,does not seem to realize; therefore the anti-static measures are based on the method of reducing volume of static electricity andlead to static electricity is the main. The commonly used methodof fabric antistatic finishing, two is blended, interwoven or othermethod of mixed woven into the fabric with conductive fiber, to lead to static electricity.

The fabric antistatic finishing of the antistatic agent is adsorbed on the surface of the fabric, the antistatic mechanism is due to moisture absorption and the electrostatic leakage. Usually the antistatic agent is a surface active agent or other hydrophilic compounds, because of too small and binding force of the fabric, the poor durability, usually after a few washing or dry cleaning will lose the antistatic effect. In the relative humidity is lower, the antistatic agent and antistatic properties of lowmoisture absorption change greatly decreased. Therefore,antistatic agent and antistatic finishing can not solve the problem of durability and low humidity conditions.

At present, the method of adding conductive fiber in the fabric isantistatic the most effective method, but also high-tech latest achievements in textile industry application. It has theadvantages of good antistatic effect, durable antistatic properties. The use of conductive fiber is the basic direction of anti electrostatic technology of textile materials. The antistaticmechanism is due to produce a very mild corona dischargebetween conductive fiber, when the voltage reaches a certainvalue, namely the corona discharge no spark of the elimination of static electricity. This phenomenon is usually considered asthe fabric of the conductive fibers in the electrostatic field, so that the air around the ionization and the formation of positive and negative ions, a fabric with static charge neutralization of positive and negative ions in the opposite, another is the chargeneutralization and environment of earth, so as to eliminate the static electricity. A significant difference between the corona discharge and electrostatic leakage is, also can well eliminate electrostatic fabric of the corona discharge in unclean, andelectrostatic leakage to ground or in the air humidity can makestatic elimination.

Application experience at home and abroad, coating type and composite type of organic conductive fiber is most suitable formanufacturing permanent antistatic textile. From the demandcharacteristics of textile products anti-static function, conductive fiber has the following two types: (1) applies to civil textile dyeing properties need various metal compound composite white highconductive organic conductive fiber; (2) adapted to specificfunctional textiles (such as clean proof overalls, electromagnetic shielding fabric) need the carbon coated or black carbon composite conductive organic conductive fiber. Organic conductive fibers such as company I used the United StatesSolutia of belong to this kind of composite conductive fiber, with its production of antistatic lining, the antistatic effect after washing 50 times not to drop, after 100 times washing can stillreach national standard anti-static overalls, anti static electricityindex.
