Abstract

The invention provides a yarn wear resistance detection method. The yarn to be detected is wound by a turning plate in an upside-down state. After the winding of the detected yarn is completed, the turning plate starts to turn over to make the yarn on one end of the turning plate turn over. Friction is carried out during the flipping process. During each flipping process of the flipping board, the yarn on the end face of the flipping plate is subjected to the friction operation for hairiness detection and analysis. In the process of detection and analysis, when it is found that the hairiness length detection and analysis data have obvious changes, the wear resistance of the yarn can be measured by the total number of times the turning plate is turned at this time; if no yarn hairiness is found in the above process. When there is an obvious sudden change in the length analysis data and there is a hairy yarn group formed on the yarn, a high-definition camera is used to photograph and analyze the yarn on the end face of the rubbing operation on the turning plate.
