With the improvement of people’s living standards, customized work clothes have become a major trend in society, and science and technology continue to develop and advance. More and more companies are equipping special work clothes for corporate special staff, which not only facilitates corporate management but also protects special workers. personal safety. How much do you know about anti-static work clothes? Let’s learn the specific content together.
Anti-static work clothes refer to uniforms sewn with anti-static fabrics as fabrics in order to prevent the accumulation of static electricity on clothing. Anti-static fabric is a fabric made by mixing conductive fibers or anti-static synthetic fibers at roughly equal intervals or evenly during weaving, or a mixture of both.
Conductive fiber refers to the general term for fibers made entirely or partially of conductive materials or sub-conductive materials using metal or organic matter. Its volume resistivity ρv∼ is between ¹04∼¹09Ω/cm. According to the distribution of conductive components in the fiber, conductive fibers can be divided into homogeneous conductive components, covered conductive components and composite conductive components. At present, the vast majority of anti-static fabrics are made of conductive fibers, especially composite types with conductive components, that is, composite fibers are mostly used.
Anti-static work clothes are made by adding conductive fibers to chemical fiber fabrics. The electricity dissipation is based on two mechanisms: charge leakage and neutralization. When grounded, the static electricity on the fabric is not only neutralized by the corona discharge of the conductive fibers, but also discharged to the earth through the conductive fibers; when not grounded, the static electricity on the fabric is eliminated by the weak corona discharge of the conductive fibers.
Practice has shown that anti-static work clothes can effectively suppress static electricity in clothing and eliminate or reduce the hazards of electrostatic discharge. When the human body carries out various activities, the electrostatic voltage value on clothing has greatly exceeded the electrostatic discharge damage threshold of many electrostatic sensitive devices. Therefore, when touching or approaching these components, the sensitive devices may be damaged. It should also be pointed out that wearing pure cotton work uniforms is generally considered safe because it prevents the accumulation of static electricity in clothing.
In fact, this view is one-sided and is basically true only when the relative humidity of the air is higher than 50%; when the relative humidity is relatively low, the charge of pure cotton products increases significantly. Tests have shown that when the relative humidity is below 30%, the charge capacity of pure cotton fabrics is equivalent to that of polyester; when the relative humidity is below 20%, the charge capacity of cotton fabrics is even higher than that of some chemical fiber fabrics.
Therefore, in areas with dry climates, we cannot expect to use pure cotton products to eliminate static electricity hazards from clothing under any circumstances. Based on the above reasons, in order to effectively prevent the harm of electrostatic discharge to the human body, operators must wear anti-static work clothes.
Business units and staff who are exposed to static environments should learn relevant corporate knowledge. They must have strict purchasing standards for anti-static work clothes, anti-static shoes, gloves and other safety protection equipment, and use them according to professional cleaning and maintenance methods. , must be meticulous and regularly detect various anti-static indicators to ensure the effective use of anti-static work clothes.
