Electrostatic hazards in flexible packaging and printing production improve product performance
Anti-static clothing is made of special anti-static clean fabric. This fabric uses special polyester filaments to weave conductive fibers 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. Different styles are provided according to the level requirements, 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. .

Anti-static professional wear refers to work clothes that are sewn with anti-static fabric as a fabric to prevent static build-up on clothing. The antistatic fabric is a fabric obtained by mixing conductive fibers or antistatic synthetic fibers or a mixture of the two at substantially equal intervals or evenly during weaving. The conductive fiber is a general term for fibers made of a conductive material or a subconductive material using metal or organic materials in whole or in part, and has a volume resistivity ρv ~ between 104 and 109 Ω/cm.
Practice has shown that anti-static overalls can effectively suppress static electricity in clothing and eliminate or reduce the electrostatic discharge hazard. The table below gives a comparison of the human body's electrification when the operator wears different overalls.
Identification of ultra-clean fabrics for anti-static clothing:
Measuring the warp and weft density: The warp and weft density of the fabric is measured by the warp and weft density mirrors, and compared.
Resistance measurement: The warp and latitudinal resistance of the fabric were measured by a surface resistance tester and compared.
The principle of comparison is:
The selection resistance is relatively small;
If the resistance is the same, select the resistance value to be stable;
Pay attention to whether the fabric is added with antistatic agent during finishing (applicable to conductive silk with only conductive fibers in the warp direction, commonly known as striped cloth). The method is to measure the warp and weft resistance by surface resistance tester, if the same, Note that with the addition of antistatic agents, the measured resistance does not represent the true level.
