摘要:

为深入了解网眼罗拉集聚纺集聚效果的影响因素,借助CFD计算流体动力学软件及MatLab工具,探讨负压、网眼罗拉表面摩擦因数对集聚效果的影响。结果表明:在定负压条件下,随着表面摩擦因数的减小,集聚效果逐渐变好,可得出临界表面摩擦因数;在变负压条件下,网眼罗拉表面临界摩擦因数与负压存在着正相关趋势,因此,需合理选择负压与网眼罗拉表面摩擦因数,以加工低能耗、低成本、高品质的集聚纺纱线。

Abstract:

For complete understanding the factors influencing the compacting effect of compact spinning with perforated roller, the effect of negative pressure and surface friction of perforated rollers on the compacting effect was investigated by using CFD and MatLab software. The results indicated that compacting effect becomes better with deceasing of the surface friction coefficient when the negative pressure is fixed, and the critical friction can be obtained. There is a positive correlation between the critical friction and the changing negative pressure. Therefore, it is necessary to choose reasonable negative pressure and surface friction of rollers for low energy consumption, low cost, and high quality of compact yarns.
