Method and device for resistance detection of conductive yarn

Abstract

The present invention provides a method and device for resistance detection of a conductive yarn. A whole conductive yarn sample is wound on an insulated rectangular plate to allow the winding conductive yarn to form a plurality of yarn sections arranged in parallel at one side of the insulated rectangular plate; the insulated rectangular plate is provided with two yarn end gap ports which are configured to respectively fix head and the tail ends of the conductive yarn sample; conductive clips of the cathode and the anode of a resistance measuring meter are respectively clamped at and connected with the end portions of the conductive yarn sample at the two yarn end gap ports to measure the resistance value of the whole conductive yarn sample; and the conductive clips of the cathode and the anode of a resistance measuring meter are respectively clamped at and connected with two ends of the yarn sections arranged in parallel, the work width of the conductive clips are required to cross the yarn sections to measure the parallel resistance value of the yarns. The method and device for resistance detection of the conductive yarn can conveniently detect the resistance value of the whole conductive yarn and conveniently detect the parallel resistance value of one set of the conductive yarns.

AI Technical Summary

Problems solved by technology

Therefore, the expansion and application of the production of conductive textiles in the industry has led to the concern of the conductive quality of conductive yarns. At present, there are no corresponding detection method standards in the field of conductive protective products at home and abroad. The upstream leading raw materials for conductive protective products are The key bottleneck to ensure the conductivity of its finished products restricts the popularization and application of such products to a certain extent. The research on the conductivity of conductive yarn is an urgent need for the development of the industry

[0003] At present, the production status of domestic conductive yarns is also mixed. The phenomenon of using diversified conductive materials in conductive yarns is becoming more and more prominent. The diversification of materials has different changes for different types of finished products, and the market is in disorderly competition. , is not conducive to the stability and improvement of product quality
