Embodiment Construction

[0018] The present invention will be described in detail below in combination with specific embodiments.

[0019] The invention is used for accurately testing the surface specific resistance and volume specific resistance of fabrics with certain geometric shapes and various specifications, as well as the thickness of the fabrics. The inventive device such as figure 1 As shown, it includes the test volume resistance system and the test surface resistance system. Both the test volume resistance system and the test surface resistance system include a stainless steel disc electrode 1 and a stainless steel ring electrode 2. The stainless steel disc electrode 1 and the stainless steel ring electrode 2 are the same layer and is in contact with the upper surface of the fabric 5, the stainless steel circular electrode 2 surrounds the circumference of the stainless steel disc electrode 1, the stainless steel disc electrode 3 is located below the fabric 5 and contacts the lower surface o...

Abstract

The invention discloses a fabric surface specific resistance and volume specific resistance testing device which is characterized in that a fabric clamping device uses a three-electrode system to serve as the testing electrode of fabric surface specific resistance and volume specific resistance, and the three electrodes include two concentric electrodes contacting with the upper surface of fabric and an electrode contacting with the lower surface of the fabric; during volume specific resistance and surface specific resistance testing, the three electrodes are respectively connected with the anodes and the cathodes of a ground resistance meter and a high resistance meter to perform measuring; a resistance testing part comprises the high resistance meter which is used for being connected with the electrodes to perform measuring, and a volume specific resistance/surface specific resistance switching switch is used for selecting whether the two electrodes for testing the volume specific resistance are connected to the high resistance meter or the two electrodes for testing the surface specific resistance are connected to the high resistance meter. The fabric surface specific resistance and volume specific resistance testing device has the advantages that the device is suitable for testing the volume specific resistance and surface specific resistance of fabric of various specifications, fabric thickness can be tested at the same time, and testing results are accurate.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a testing device for fabric surface specific resistance and volume specific resistance. Background technique [0002] The conductance of materials includes surface conductance and bulk conductance. Usually when testing the electrical conductivity of fabrics, it is provided according to ASTM D257-14, GB / T 1400-2006 and ASTM D 4238-1990, GB / T 12703.6-2010, the test method for the volume resistivity and surface resistivity of solid insulating materials Test method for fabric resistance test. Due to the contact resistance between the electrode and the material, in order to overcome the contact resistance, the electrode is usually selected with a larger weight to eliminate the impact of the contact resistance on the measurement, so a ring with a larger mass is also used in the three-electrode test system mentioned in the above standard and cylindrical electrodes. In the actual test, ...
