How to buy real ESD anti-static fabrics
Generally, anti-static fabrics will have black conductive threads, but this can be true or 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 procurement of many companies, it is a headache to purchase high-quality anti-static clothing. The first is that I don’t know how to test its anti-static clothing. The second is that after purchasing the anti-static clothing, the anti-static clothing passed the test. However, after using it for a period of time, I discovered that its product does not have anti-static functions and is no different from ordinary work clothes. the difference. Take anti-static work clothes as an example. When purchasing, the point-to-point resistance was tested and it met the national standards. However, after the clothes were cleaned several times, when the point-to-point resistance was tested, it was found that they no longer met the national anti-static clothing testing requirements. specification. The main problem is that when purchasing this anti-static clothing, the fabric of this anti-static clothing has been treated with anti-static agent, so no matter how the point-to-point resistance is tested, it can meet the national standards.
The specific way to distinguish anti-static clothing is that you wash the cloth and wash it several times. If it is fake, then the anti-static liquid will no longer be anti-static after being washed away. If it is made of conductive thread, the effect will probably remain the same. Details 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, don't just try to quote cheap. Quotation is not the key, the key is whether the quality of anti-static clothing has achieved the effect of preventing static electricity.
