How to buy real anti-static clothing
Generally, the fabrics used in anti-static clothing will have black conductive yarns, but there are real and false points. Because anti-static fabrics are expensive, some markets will use ordinary polyester fabrics to print black threads, and then soak them in anti-static liquid. Medium, so that the cloth has a certain anti-static effect in a period of time.

For purchasers of many companies, buying high-quality anti-static clothing is a headache. First, I don’t know how to test the anti-static clothing. Second, after purchasing the anti-static clothing, the anti-static clothing is qualified, but after a period of use, it is discovered that the product does not have anti-static function, which is nothing like ordinary work clothes. the difference.
Take the anti-static work clothes as an example. When purchasing, the point-to-point resistance was tested to meet the national standard. However, after the clothing was cleaned for several times, the point-to-point resistance test found that it did not meet the national anti-static clothing test. specification. The main problem is that when purchasing this anti-static clothing, the fabric of this anti-static clothing has been impregnated with an anti-static agent, so no matter what the point-to-point resistance is tested, it can reach the national standard.
The detailed method of distinguishing anti-static clothing is that you wash the fabric and wash it a few more times. If it is fake, then the anti-static liquid will not be anti-static if it is washed off. If it is a conductive wire, the effect is probably the same, detailed The parameters are usually the surface resistivity of 10^6~10^9 ohms.
Therefore, when purchasing anti-static clothing, the quality of the anti-static clothing is the key.
