There are many kinds of anti-static clothing on the fabric, but basically divided into 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 Belltron 9R series of conductive fibers of the Japanese bell spinning company are embedded in the warp or weft direction. It has high-efficiency, permanent anti-static, dust-proof performance, thin and smooth, and clear texture. A special overlocking machine is used in the process of making garments, which effectively reduces the generation of particles. The dust-free fastening tape avoids contamination of the environment by hair loss. According to the level requirements, different styles are provided, and conductive fibers are used to make the parts of the garment maintain electrical continuity; the sleeve tube is a unique double-layer structure, and the inner layer is made of conductive or anti-static rib to meet the requirements of high-level dust-free environment. The anti-static clothing adopts stainless steel fiber, sub-conductive fiber, anti-static synthetic fiber and polyester-cotton blended or mixed-woven fabric, which can automatically corona discharge or leak discharge, can eliminate clothes and human body charging, and also provide anti-static hats and socks. ,shoe. Its performance index is in line with GB12014-89 standard: cloth charge density ≤ 5μC
For different industries, electronics, chemicals, pharmaceuticals, aerospace, precision machinery, automobiles, and everyday life, the requirements of different grades of anti-static clothing are used.
For the electronics industry, it is mainly based on how high the requirements of the manufactured products are on static electricity, and secondly on the requirements for static electricity in all aspects of manufacturing. For example, semiconductor chip manufacturers have the highest requirements for electrostatic sensitivity, and some products have a withstand voltage of 50 volts. Therefore, the requirements for the workers' work clothes not only require low voltage, but also the electrostatic discharge effect is very good. For OEM foundries, the requirements for anti-static clothing are lower because they are mostly processed or assembled in a certain part of the product. Of course, the cost is a little lower.
Therefore, it is recommended that the factory must first understand the real requirements when purchasing anti-static clothing. It is best to consult some professional anti-static companies to avoid unnecessary costs.
General law:
Anti-static coveralls for semiconductor and chip factories
Anti-static split suit for pharmaceutical and mobile phone motherboard patch shop
Circuit board, mobile phone rear line finished assembly process for anti-static jacket
Conductive silk anti-static clothing is generally used in the workshop of the manufacturer. Polyester/cotton is used in office areas, outdoors or in areas where static electricity is not too high.
