Abstract

Placing a swirl nozzle composed of a yarn channel and an air-jet nozzle in a traditional ring spinning frame can reduce yarn hairiness. In this study, two types of swirl nozzles, namely, the circular swirl nozzle and the elliptical swirl nozzle, are designed to optimize the inside structure of the swirl nozzle and improve the yarn quality. Yarn performance is evaluated based on the hairiness, breaking strength, and evenness of the yarn. Experimental results show that the two types of swirl nozzles have effective effects on the ring yarn qualities compared with the traditional method. The mechanisms of the said effects can be explained via yarn de-twisting and re-twisting under the vortex action in the yarn channel. Yarn channels have different effects on yarn properties because of their different airflow patterns. The circular swirl nozzle is found to produce better yarn properties, including S3 value (the total number of hairiness equal to or exceeding 3 mm per 10 m), breaking strength, and evenness than the elliptical swirl nozzle under similar processing parameters
