Abstract: This paper introduces the advantages and market demand of using air-jet vortex spinning to produce core-spun yarns, and reviews its formation principle, especially for the process of air-jet vortex core-spun yarn containing a metal wire. From the perspective of the equipment, the paper elaborates on the current research status of the processing equipment for air-jet vortex core-spun yarns. In the end, the followup research and development direction of air-jet vortex core-spun yarn processing equipment is pointed out, so as to provide a reference for its future development and progress.

Key words: air-jet vortex spinning; core-spun yarn; principle of yarn formation; equipment; research progress
