Airjet (Vortex) Yarns

Vortex spinning can be viewed as a refinement of jet spinning, or a natural development in fasciated yarn technology. As in all other fasciated yarns, the structure of vortex yarn consists of a core of parallel fibres held together by wrapper fibres.

This has been revealed by examining an untwisted vortex yarn sample under the Scanning Electron Microscope. Subsequently, the physical properties of the vortex and air-jet yarns produced from different polyester cotton blends were compared. Results indicated that vortex yarns have tenacity advantages over air jet yarns, particularly with high cotton contents
