Anti-static ESD clothing: which fabric has better anti-static performance?
As we all know, the fabric of antistatic clothing determines the performance of antistatic clothing, so how to choose antistatic clothing?
The fabrics of antistatic clothing are usually polyester and polycotton. Polyester-cotton anti-static ESD clothing fabrics are soft and breathable, more comfortable to wear, and have more editions, but most companies still choose polyester-cotton anti-static ESD clothing, because polyester-cotton fibers are very long, so it is not easy to produce dandruff, and the density of the fabric can prevent the fabric or dust from falling off, color fastness and washing.
Anti-static overalls, anti-static split suits, anti-static onesies
According to the spacing and arrangement of the embedded conductive filaments in the fabric, the commonly used anti-static fabrics are mainly divided into 0.5mm, 0.5mm, 0.25mm and 0.25mm. The reason why anti-static ESD clothing is anti-static is because of the conductive filaments embedded in its fabric, the smaller the distance between the conductive filaments, the better the anti-static performance of the grid, and the better the anti-static performance of the stripes.
The resistance of antistatic insulating materials is different. Generally, the insulation resistance is greater than 1012Ω, while the antistatic resistance is between 106Ω~1012Ω. The insulation is not conductive, and the anti-static material is made, but the resistance value is relatively large, and the standard requires it to be between 10^6 and 10^9.
The performance of anti-static shoes and insulated shoes is different. Anti-static shoes are made by adding anti-static materials to the soles. Anti-static shoes have weak conductivity and can guide the excess charge of the human body to the ground, avoiding charge accumulation and electrostatic discharge, thereby eliminating static electricity in the human body. The sole of the shoe is made of non-conductive insulating material to insulate the human body from the ground. Even contact with conductive materials does not cause electric shock to the human body.
Anti-static shoes and insulated shoes have different applications. Anti-static shoes are commonly used in precision electronics, components and other electronic enterprises, optical instruments, pharmaceutical companies, etc., anti-static shoes in the process of use, friction does not produce static electricity, can protect electronic products from static damage, insulated shoes are mainly to protect the body from the influence of electricity, on the ground, and protective clothing has no special requirements, generally in the electrical aspect, to prevent the generation of stepping voltage and electric shock, but also to prevent grounding conduction and electric shock accidents.
