Material identification of anti-static clothing
Anti-static clothing is made of special anti-static clean fabric. This fabric is made of special polyester filament, and conductive fibers are interwoven in warp or weft direction. It has excellent anti-static and dust-proof performance, thin and smooth, and clear texture. In the process of making garments, special overlock machines are used to effectively reduce the generation of particles. The dust-free hook and loop tape avoids polluting the environment due to hair loss. Different styles are provided according to the level requirements, and conductive fiber is used to sew all parts of the garment to maintain electrical continuity; the sleeves and trousers have a unique double-layer structure, and the inner layer uses conductive or anti-static ribs to meet the requirements of other dust-free environments.
Consumer principle:
Anti-static professional wear refers to work clothes sewn with anti-static fabric as the fabric to prevent the accumulation of static electricity on clothing. Anti-static fabrics are fabrics made by mixing conductive fibers or anti-static synthetic fibers or both at roughly equal intervals or evenly during weaving. Conductive fiber refers to a general term for fibers made of conductive materials or sub-conductive materials that are wholly or partly made of metals or organics, and their volume resistivity ρv is between 104 and 109Ω/cm.
Practice shows that anti-static work clothes can effectively suppress static electricity in clothing and eliminate or reduce the hazards of electrostatic discharge. The following table shows the comparison of the human body charged when the operator wears different work clothes.
Identification of ultra-clean fabrics for anti-static clothing:
Measure the warp and weft density: use a warp and weft density mirror to measure the warp and weft density of the fabric and compare them.
Resistance measurement: use a surface resistance tester to measure the warp and weft resistance of the fabric and compare them.
The principle of comparison is:
Choose a relatively small resistance;
If the resistance is the same, choose a stable resistance value;
Pay attention to distinguish whether antistatic agent is added to the fabric after finishing (applicable to conductive silk with only conductive fibers added in the warp direction, commonly known as striped cloth). The method is to measure the resistance in the warp and weft directions with a surface resistance tester, if the same, It means that with antistatic agent, the measured resistance does not represent the true level.
