Authoritative anti-static fabric testing method

●Measure the latitude and longitude density of the anti-static fabric: Use a latitude and longitude density measuring mirror to measure the longitude and latitude of the fabric for comparison.

●Side resistance: Use a surface resistance tester to measure the warp and weft resistance of the fabric for comparison

Select the smaller one for the above two test results

If the resistances are the same, choose the one with stable resistance value

Pay attention to distinguish whether antistatic agent is added to the fabric during finishing (applicable to conductive silk with only conductive fibers added in the warp direction). The method is to use surface resistance The tester measures the warp and weft resistance of the fabric respectively. If they are the same, it means that an antistatic agent has been added, and the measured resistance does not represent the true resistance level.

●Look at the microstructure: use a magnifying glass to look at the quality of the cloth surface, and compare the size of the gaps between the fibers (and (related to the dust filtration rate), check whether there are attachments on the fiber surface (related to the amount of dust generated), and whether the fibers are arranged neatly and have consistent tightness. If the tightness is inconsistent, some of the fibers sent during wearing and cleaning will be simply sanded, which will affect the future wearing effect. .

●Check conductive fibers: Conductive fibers are the key raw materials in antistatic fabrics. The focus of checking conductive fibers is to see if Add conductive fibers according to specifications and standards, as well as what kind of conductive fibers to add and the quality of conductive fibers.

Detection method: Use scissors to cut the fabric along the edge of the black conductive fibers, separate the black conductive fibers, and use a high-power magnifying glass to see if there are one or more thick ones. fibers, and use a surface resistance tester to detect the resistance of the separated conductive fibers. Continuously separate multiple conductive fibers and measure them one by one to deduce whether each black silk contains conductive fibers.

● Contrast fabric Process parameters: The supplier is required to provide the basic parameters of the fabric, such as yarn weave, fabric composition, finished product width, etc. The key depends on what kind of conductive fiber the fabric provided is used.
