An analysis of the air-jet yarn texturing process. Part 3, Filament behaviour during texturing

Experiments performed with a current industrial-texturing nozzle on a specially designed singlehead texturing machine are described. These involve the use of high-speed still and cine photography, together with measurements of yam speed on emergence from the nozzle and yarn-tension measurements at various stages of the process. The results of these experiments provide a better understanding of the filament behaviour during the texturing process. They also provide useful information regarding the effects of texturing speed, overfeed ratio, and texturing with and without water on the mechanisms of the process.
