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 judgment method of the weaving mode of a conductive fabric and the type of conductive yarn. The method includes the steps of laying the to-be-detected fabric on a tabletop atfirst and utilizing a universal meter to randomly measure the resistance of different continuous parts of the to-be-detected fabric in the warp direction and the weft direction; then, clipping the to-be-detected fabric into strip-shaped samples and fixing the two ends of each fabric sample; placing the fabric samples on a judgment device, conducting data collection according to resistance / currentchanges of the to-be-detected fabric samples during constant-speed stretching and obtaining a relational graph between the resistance / current and time or between the resistance / current and stretching; according to the features of the relational graph, judging the weaving mode of the to-be-detected fabric and judging the type of the conductive yarn. The judgment device involved in the judgment method includes the fabric samples, wherein the two ends of each fabric sample are fixed and clamped by electrodes; the fabric samples are connected with a switch, a standard resistor and a DC power source in series, the standard resistor is connected with low-pass filtering in parallel, and the low-pass filtering is electrically connected with a data collecting device and a PC. The weaving mode of the fabric can be judged quickly and accurately, and the type of the conductive yarn in the fabric is also judged.

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 ...
