Loop formation mechanism in the air-jet texturing process

A brief introduction to the air-jet texturing process is given, with reference to similarities between air-jet textured yarns and spun yarns, differences between them and stretch yarns, and developments in texturing nozzles. Researches undertaken at various universities on the investigation of the loop formation mechanism are reviewed. An alternative explanation of the loop formation mechanism is offered by detailed reference to current research in the Department of Mechanical Engineering at Loughborough University of Technology, this being based on high-speed photography and flow measurement methods applied mainly to the standard core HemaJet produced by Heberlein of Switzerland. It is argued that the suggested mechanism applies generally to all texturing nozzles.
