Description

Technical Field

[0001] The utility model relates to the technical field of textile electrostatic performance testing, in particular to a device for automatically testing point-to-point resistance of fabrics. Background Art

[0002] The detection of surface resistivity of textile fabrics is one of the most common detection items in the production and trade of textiles. The commonly used detection instrument is a point-to-point resistivity tester, which is specially used to measure the surface resistance of anti-static engineering. It can measure the point-to-point resistance of anti-static fabrics, the surface resistivity of anti-static clothing, etc. It can be used by anti-static product manufacturers, standard metrology departments, and scientific research units. When using the point-to-point resistivity tester, a sample of textile fabric is taken, placed on an insulating table, and then the two test electrodes of the tester are placed on the sample at a certain distance to detect the resistivity. At present, the two test electrodes need to be placed manually, which has the following defects:

[0003] Each sample needs to be tested for 5 sets of data, and each set of data must be measured through the above steps. In order to prevent the risk of electric shock, the operator needs to turn off the power after each set of data is tested, and then turn on the power again after the electrode group is rearranged. Repeated switching is time-consuming and may cause wear and tear on the tester. In addition, the operator may forget to turn off the power, resulting in the risk of electric shock. Improper operation may cause the risk of electric shock.

[0004] Manual placement of test electrodes may result in the center distance of the electrodes not meeting the standard or the two electrodes not being placed in a straight line, resulting in inaccurate final data. Utility Model Content
