How Anti-Static Cleanroom Clothing Works
The approach to preventing static charge accumulation in cleanroom clothing is to conduct static charge from objects as quickly as possible through a specific pathway, dispersing or dissipating it. Therefore, anti-static cleanroom clothing should be made from fabrics containing highly conductive fibers. Currently, there are three main types of anti-static fabrics in use:
1. Exploiting the humidity dependence of the anti-static effect. Anti-static finishing, which involves adding hydrophilic polymers (surfactants) during spinning, allows the fabric to absorb moisture from the air, reducing surface impedance, minimizing static charge accumulation, and effectively dissipating static electricity from the human body.
2. Utilizing the conductivity of fibers. Antistatic agents and carbon black particles are added to the raw fiber to create conductive fibers. Through blending, interlacing, braiding, interweaving, or interweaving, the conductivity of the fibers or fabric is enhanced, creating anti-static fabrics that dissipate charge and prevent static charge accumulation.
3. Blended fabrics are created by incorporating a certain amount of metal fibers into the fibers. These fabrics offer excellent stability and washability. Anti-static work clothes (GB12014-1989), listed in the catalog of special labor protection products, are made of anti-static fabric to prevent static buildup and are suitable for use in fire or explosion hazardous locations. The anti-static fabric is manufactured by interweaving roughly evenly or uniformly interweaving anti-static fibers made entirely or partially of metallic or organic conductive materials, anti-static synthetic fibers, or a mixture of both.
