So how to distinguish whether antistatic agent is added to the fabric (mainly conductive wires or striped cloth with conductive fibers added in the warp direction)? The specific method is to test the warp and weft resistances in turn through a surface resistance tester. If they are the same, it means that antistatic agent exists, but the measured resistance does not represent the actual level.
Examine the microstructure; Check the quality of cloth surface with a high magnification magnifying glass, compare the gap size between fibers (related to the dust filtration rate), and check whether there are any attachments (dust production) on the fiber surface, whether the fibers are arranged neatly and whether the tightness is consistent (if they are inconsistent, some fibers are easy to be sanded when washed and easy to accumulate dust when worn).
Detection of conductive fiber: As the key fabric of ultra-clean antistatic clothing, the detection method lies in whether conductive fiber is added according to the specification and what kind of conductive fiber is added.
The specific method is to carefully cut the fabric along the edges of the conductive fibers with scissors, then separate the conductive fibers, use a magnifying glass to see if there are several coarse fibers, and use a surface resistance tester to test the resistance. Generally speaking, conductive wires are made of carbon organic conductive fibers, black or gray, with a value of about 200, ranging from 1F-6F.
