Different functions of anti-static clothing
Different functions of various anti-static clothing
There are many types of anti-static compliant fabrics, but basically there are two types of conductive silk and TC cotton. According to the weaving method of conductive silk, it is divided into straight fabric and mesh fabric.
The fabric is made of special polyester filament, and the warp or weft direction is woven with Japanese Bell Textile Company BELLTRON9R series conductive fiber. It has the characteristics of high efficiency, permanent anti-static, dustproof, thin and smooth, and clear texture. In the process of making garments, special overlock machinery is used to effectively reduce the generation of particles. The dust-free hook-and-loop fastener avoids polluting the environment due to hair loss. Provide different styles according to level requirements, and use conductive fiber to sew, so that the clothing parts maintain electrical continuity; the sleeve pants are a unique double-layer structure, and the inner layer uses conductive or antistatic ribs to meet the requirements of high-level dust-free environments Anti-static clothing is made of stainless steel fiber, sub-conducting fiber, anti-static synthetic fiber and polyester-cotton blended or woven fabric, which can automatically corona discharge or leakage discharge, can eliminate clothing and human body charging, and provide anti-static hats and socks ,shoe. Its performance index accords with GB12014-89 standard: cloth charge density ≤5ΜC
For different industries, electronic, chemical, pharmaceutical, aerospace, precision machinery, automobiles, and daily life will use different levels of anti-static clothing requirements.
For the electronics industry, it depends mainly on how high the static electricity requirements of the manufactured products, and secondly on the static electricity requirements in all aspects of manufacturing. For example, semiconductor chip manufacturers have the highest requirements for electrostatic sensitivity, and some products have a voltage resistance of 50 volts. Therefore, the requirements for workers ’uniforms not only require a low voltage, but also have a very good static discharge effect. For OEM foundries, because most of them are processing or assembly of a certain part of the product, the requirements for anti-static clothing are lower. Of course the cost is lower.
Therefore, it is recommended that when purchasing anti-static clothing, factories must first figure out their true requirements. It is best to find some professional anti-static companies to consult, so as not to pay some unnecessary costs.

Applicable anti-static coveralls for semiconductor and chip factories
Anti-static split suit for pharmaceutical and mobile phone motherboard patch workshop
The antistatic jacket is suitable for the assembly process of circuit board and mobile phone rear line finished products
Conductive silk anti-static clothing is generally used in the workshop of the manufacturer. Polyester and cotton are mostly used in the office area, outdoor or in areas with low static electricity requirements.
