What is the antistatic principle of antistatic clothing?


Fabrics made of anti-static clothing are generally added with conductive fibers to reduce the resistance of the garment (generally controlled below 10 9 ohms), which is conducive to conductive charge discharge.

 

ESD clothing is best used with anti-static wrist straps, anti-static shoes, and anti-static flooring. Static electricity on the human body and clothing can be discharged into the earth through wrist straps or anti-static grounding devices to prevent static electricity. .

ESD clothes sewn with antistatic fabrics for the fabric. The antistatic fabric is a fabric formed by mixing electrically conductive fibers or antistatic synthetic fibers or a mixture of both of them at substantially equal intervals or evenly during spinning. The conductive fiber refers to a generic name of a fiber made of a conductive material or a sub-conductive material using all or part of a metal or an organic material, and has a volume resistivity between 104 and 109 Ω/cm. According to the distribution of the conductive component in the fiber, the conductive fiber can be divided into three types: a conductive component uniform type, a conductive component overlay type, and a conductive component composite type. At present, the vast majority of anti-static fabrics are made of conductive fibers, and in particular, composites of conductive components are used, that is, composite fibers are the most used.

 

The anti-static clothing made of conductive fiber is added to the chemical fiber fabric, and the elimination of electricity is based on the leakage and neutralization of the charge and the two mechanisms. When grounded, the static electricity on the fabric is neutralized by the corona discharge of the conductive fiber, and can also be discharged through the conductive fiber to the ground; when it is not grounded, it is eliminated by means of a weak corona discharge of the conductive fiber.
