Problems solved by technology

When analyzing the fabric, it is necessary to analyze the weaving method of the fabric. Generally, the fabric needs to be disassembled and analyzed. This process can accurately determine the weaving method of the fabric, but the disassembly process needs to be completed manually and is time-consuming.
When the color, shape and feel of the conductive yarn in the fabric are close to or consistent with the color, shape and feel of the non-conductive yarn in the fabric, or even when it is necessary to distinguish the type of conductive yarn used in fabric manufacturing, manual direct observation of the fabric is relatively difficult. It is difficult to give a quick and effective judgment
At present, there is no method for quickly detecting the weaving mode of conductive fabric and identifying the type of conductive yarn in the fabric in the prior art literature

Abstract

The invention discloses a weaving method of a conductive fabric and a method for judging the type of the conductive yarn. The steps are as follows: firstly spread the fabric to be tested on a table, and use a multimeter to randomly measure the warp and weft of different continuous parts of the fabric to be tested. Then cut the fabric to be tested into a strip sample; then fix the two ends of the fabric sample; place the fabric sample on the judging device, and check the resistance / current change of the tested fabric sample during the stretching process at a constant speed Carry out data collection, and obtain the relationship diagram of resistance / current versus time or resistance / current versus elongation; judge the weaving method of the tested fabric and the category of all conductive yarns according to the characteristics of the relationship diagram. The judging device used in this judging method includes a fabric sample fixed at both ends and holding electrodes, the fabric sample is connected in series with a switch, a standard resistor and a DC power supply, the standard resistor is connected in parallel with a low-pass filter, and the low-pass filter and data acquisition Electrical appliances and PC electromechanical connection. The invention can quickly and accurately determine the weaving mode of the fabric and the type of the conductive yarn in the fabric.

Description

technical field [0001] The invention belongs to the technical field of conductive fabric detection, and in particular relates to a weaving method of conductive fabric, a conductive yarn type judging device and a judging method thereof. Background technique [0002] At present, in order to achieve antistatic, electromagnetic shielding and conductive effects in the existing technology, conductive fabrics generally have the following weaving methods. The first is to weave conductive filaments or short fiber yarns into the fabric at intervals. Conductive fabrics The whole is not conductive, but only conductive filaments or conductive spun yarns are conductive; the second is to use conductive filaments or spun yarns to weave, and the fabric is conductive as a whole or along a certain system. The yarn direction is conductive; the third is to use conductive materials to coat the fabric to make the whole conductive. When analyzing the fabric, it is necessary to analyze the weaving ...
