Fabric surface resistance test method and test fixture

Abstract

The invention relates to a fabric surface resistance test method and a test fixture. The method comprises the steps of weaving a conductive fabric into a rectangular shape, weaving flexible electrodesat two ends of the conductive fabric, respectively placing an electrode block on the two flexible electrodes, connecting the electrode blocks with a power supply to form a loop, measuring the currentof the loop, and dividing the voltage of the power supply by the current of the loop to obtain the surface resistance of the fabric. The fixture comprises a flat plate, a clamp a, a clamp b, a detachable electrode block, a mechanism I, a mechanism II, a mechanism III a mechanism IV. The flat plate is used for laying the conductive fabric to be measured; the clamp a and the clamp b are located onthe two opposite sides and used for clamping the conductive fabric to be measured; the electrode block is connected with the mechanism II, the mechanism III and the mechanism IV at the same time; andthe mechanism II, the mechanism III and the mechanism IV are used for moving the electrode block in the X direction, the Y direction and the Z direction respectively. The test method is easy to operate. The fabric surface resistance can be rapidly and accurately measured. The test device is easy and convenient to operate, and the measurement error is small.

Description

technical field [0001] The invention belongs to the technical field of intelligent textiles, and relates to a fabric surface resistance test method and a test fixture. Background technique [0002] With the development of smart textiles, the demand for conductive textiles is also increasing. Conductive textiles are widely used in sensors, heating clothing, textile capacitors, and electromagnetic shielding fabrics. The principles of these applications work by converting electrical signals into mechanical and thermal signals. Under small changes, devices that can accurately measure electrical signals are particularly important. At the same time, conductive textiles will deform during wearing, so it is necessary to study the influence of deformation on fabric resistance. [0003] The flexible conductive fabrics that are widely used in daily life are mainly conductive knitted fabrics and conductive woven fabrics. During the weaving process of conductive fabric, the interlacin...
