How to buy a real anti-static clothing

Usual antistatic fabric , there will be black conductive wire, but there are true and false , because the high cost of anti-static cloth , some markets will use the usual polyester fabric printing black line , and then soaked in anti-static solution, the cloth has a certain period of time antistatic effect.
About a lot of procurement , the procurement of high quality anti-static clothing , is a vexing problem . First, I do not know how to detect its anti-static clothing , the second is to pick up a anti-static clothing , in the acquisition of the division of qualified, but with some time, only to find that their products do not have the anti-static function, and normally there is no difference of goods . Take anti-static work clothes , in the time of purchase , point to point resistance measurement device to reach the national standard, however , clothes washing several times in the future , its point resistance measurement , it was found , is now inconsistent with national anti-static service testing specifications. The main problem is that, in the purchase of this anti-static clothing after midnight, this fabric has anti-static clothing with antistatic agents disseminated over , so whatever point resistance tests can reach national norms.
Detailed distinction , you can wash the cloth , wash a few times , if it is false, it is not washed off antistatic liquid antistatic , if it is electrically conductive wire , the role is probably the same, detailed parameters are usually is the appearance of resistance 10 ^ 6 - 10 ^ 9 ohms.
So when in the acquisition of goods , reminds us that the quality of goods is vital, not only to offer goods cheaper Fig . Quotations are not crucial , the key lies in the quality of goods is not reached to prevent static.
