How to buy real anti-static clothing
Usually, the fabrics used in anti-static clothing will have black conductive threads, but this is true and false. Because the cost of anti-static fabrics is high, some markets will use ordinary polyester fabrics to print black lines, and then soak them in anti-static liquid. , so that the cloth has a certain anti-static effect for a period of time.
For the purchasers of many companies, buying high-quality anti-static clothing is a headache. First of all, I don't know how to test its anti-static clothing. Second, after purchasing the anti-static clothing, the anti-static clothing has passed the test, but after using it for a period of time, I found that the product does not have anti-static function, and it has nothing to do with ordinary work clothes. the difference.
Take anti-static work clothes as an example. When purchasing, the point-to-point resistance was detected, which reached the national standard. However, after the clothing was cleaned several times, it was found that the point-to-point resistance test did not meet the national anti-static clothing test. specification. The main problem is that at the time of purchasing this anti-static clothing, the fabric of this anti-static clothing has already been impregnated with anti-static agent, so no matter how 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 several times. If it is fake, the anti-static liquid will not be anti-static after washing it off. The parameters are usually the surface resistivity of 10^6~10^9 ohms.
Therefore, when purchasing anti-static clothing, the quality of anti-static clothing is the key, not just a cheap price. Quotation is not the key, the key is whether the quality of anti-static clothing has achieved the effect of preventing static electricity.
