Research into reducing the hairiness of ring spun yarn by a swirler

A swirler can be fixed on the ring frame.In the process of yarnspinning,the rotating airflow inside the swirler can exert an effect on the twisting formation of yarn,thus improving the quality of yarn.The structure of the swirler and its mounting position on the ring frame are introduced.Meanwhile,the experiment is conducted and the air pressure inside the swirler and the influence of the swirler′s structure upon yarn hairiness are analyzed.Moreover,a comparative experiment is carried out on hairiness,breaking strength and unevenness of yarns before and after the swirler is fixed on the ring frame.The results show that the hairiness on the yarn surface is reduced,breaking strength and evenness improved after fixing the swirler.
