Anti-static clothing fabric and test conductive fiber
Use the surface resistance tester to measure the warp and weft resistance of the fabric, and compare them. Choose a smaller resistance. If the resistance is the same, choose a stable resistance value;
Pay attention to whether the fabric is added with antistatic agent during finishing (applicable to conductive silk with only warp direction and conductive fiber, commonly known as striped cloth). It means that antistatic agent is added, then the measured resistance does not represent the true level.
Look at the microstructure: look at the quality of the cloth with a high magnifying glass, compare the size of the gap between the fibers (related to the dust filter rate), see if there are attachments on the surface of the fiber (related to the amount of dust), and see if the fibers are arranged neatly and tightly. (If the looseness is inconsistent, some loose fibers are easy to scrub when wearing and washing, and will dust when wearing later).
Check conductive fiber: conductive fiber is the key raw material in anti-static ultra-clean fabric, check conductive fiber is to see if conductive fiber is added according to the specification and what kind of conductive fiber is added
The inspection method is: carefully cut the fabric along the edge of the black conductive fiber with scissors, and separate the black conductive fiber, use a magnifying glass to observe whether there is one or several relatively thick fibers, and use the surface resistance test The instrument measures the resistance of the separated conductive fibers. Dismantling several pieces in succession can basically determine whether each black wire in the fabric contains conductive fibers. (The conductive silk is made of carbon organic conductive fiber, which is black or gray, generally around 20D, between 1F and 6F. In order to meet the strength requirements when weaving, an ordinary black or white polyester fiber needs to be combined fiber)
