Background

The ring is one of the key parts of ring spinning frame, and has the main function of matching with the traveller, twisting the fiber strand output by the drafting mechanism through the high-speed rotation of the traveller to form a yarn with certain strength, and winding the yarn on the ring bobbin. During spinning, the steel ring and the steel traveler rotate at high speed along the ring track, and the high-speed sliding non-lubricating friction causes abrasion and high temperature of the ring and the steel traveler. When the abrasion reaches a certain degree, the quality of the yarn is fluctuated and even worsened, the broken ends are increased, the yarn needs to be periodically replaced, and the yarn is a fixed consumption of a spinning mill. In addition, because the ring and the traveller are a pair of dry friction pairs, high temperature can be generated at high speed instantly, particularly when the ring or the traveller is worn, the traveller can not run smoothly, the instantly generated temperature can be higher, and when the spandex core-spun yarn, the filament core-spun yarn and other varieties are produced, the traveller can fuse spandex filaments and chemical fiber filaments to cause quality problems.
