Benefits of wearing anti-static clothing in electronics factories
Our country has requirements for anti-static work clothes in terms of clothing structure, anti-static performance, strength, etc. The manufacturing structure of clothing directly affects its anti-static effect. Therefore, the structural design of anti-static work clothes must ensure:
Metal accessories are generally not allowed on anti-static work clothes. When metal buttons and zippers must be used, it should be strictly ensured that the metal accessories are not directly exposed when worn to avoid sparks caused by discharge, causing fires and explosions.
Anti-static work clothes should all be made of anti-static fabrics without lining. When lining (pockets, reinforcement cloth, etc.) must be used, the exposed area of the lining should be less than 20% of the exposed area of the entire anti-static clothing; for cold-proof clothing or other anti-static clothing with special requirements, when the exposed area of the lining exceeds 20% of the exposed area of the entire anti-static clothing, the mask and lining should be detachable. The national standard for the anti-static performance of anti-static work clothes has put forward requirements for the amount of charge on a single piece of clothing under certain washing resistance conditions: for qualified anti-static work clothes, each finished product must be marked with the manufacturer name (or factory mark), factory address, product name, trademark, size specification, product grade, and production date; each package must indicate the item number, product name, size, grade, production unit, and factory date, and be accompanied by product instructions, etc. Anti-static clothing is dust-proof and anti-static, which is the main feature of this clothing. Dust-free is the key among the keys. Anti-static work clothes are generally made of polyester. The main thing is to achieve the best dust-free, which is why dust-free anti-static clothing is separated from anti-static clothing!
At present, the anti-static fabrics on the market are mainly of the following types:
Anti-static fabrics are ordinary fabrics mixed with conductive fibers. This kind of anti-static fabric is now generally accepted and recognized because it is not affected by the environment. The antistatic performance of this antistatic fabric is related to the type of conductive fiber and the distribution of conductive metals, graphite, carbon black, etc. in the fiber. It can be divided into four types: uniform conductive component type, conductive component covering type, conductive component composite type and conductive component mixed type. Among them, other composite conductive fibers containing conductive components such as carbon black and graphite can be directly used for weaving filaments. If a conductive filament is embedded in the warp yarn at a certain interval (such as about 1.5 cm), a good antistatic effect can be obtained. It is currently the best conductive fiber for weaving antistatic clothing.
