Numerical simulation of the yarn formation process in Rieter air jet spinning
Original language description
This paper presents a three-dimensional numerical simulation of the airflow field inside Rieter air jet spinning nozzle. The velocity and pressure distribution were analyzed to describe the principle of yarn formation. The analysis of velocity components and static pressure revealed how the air vortices are created inside the nozzle. A theoretical study along with experimental verification was performed to investigate the influence of nozzle pressure on air jet yarn tenacity and the results were in good agreement. The results show that increasing nozzle pressure resulted initially in improving yarn tenacity but at high pressure tenacity deteriorates.
