Abstract:

The structural paaameters (the distance from the front roller nip point to the inlet of hollow spindle, guidance body structure, jet orifice structure, hollow spindle structure, and vortex chamber structure) of nozzle play a significant role in determining the spinning quality. The fundamental research progress in nozzle structure was reviewed. The advancement of nozzle structure techniques and the associate numerical simulation method on practical nozzle structure optimization is analyzed. In addition, the important influence of the main structural parameters on the spinning quality through the existing research was emphasized, and the causes of different optimal structural parameters on flow field was analyzed by studying the coupling of fiber and airflow and the spinning experiment. The shortcomings of relying on flow field analysis separately were expounded. It is suggested that the appropriate flow field prediction model should be selected and the analysis of considering fiber properties is more valuable. Finally, it is suggested several meaningful conclusions and recommendations for future direction, facilitating the fast development of this wonderful vortex spinning technology.
