Effect of Negative Pressure on Yarn Quality in Compact Spinning with Inspiratory Groove

Abstract:

The flow field in condensing zone of compact spinning with inspiratory groove was developed with Fluent 6.3 and the distribution of velocity was analyzed too. Also the effect of negative pressure on the yarn quality was analyzed and the experiment was done to prove the effect of negative pressure on the yarn qualities. The results show that the fiber can not be compacted well when negative pressure is too small, but it will add the energy consumption, attach the fibers firmly to the bottom of the compact groove by the effect of flow field and reduce the fiber migration, cause the fibers to be absorbed from the holes or the holes to be plugged when the negative pressure is too big. Therefore, in order to ensure the fibers being compacted well and reduce the energy consumption, the selection of negative pressure in compact spinning with inspiratory groove should be less than -3000pa.
