Optimization of flow guiding device for siro condensed spinning
摘要
Abstract
To evaluate the application effect of three condensed flow guiding devices in the spinning process,a 6.025 g/10 m viscose roving was selected for siro condensed spinning experiment.By controlling the negative pressure and installing different flow guiding devices,five spinning schemes were designed for spinning,and the yarn quality of the five spinning schemes was tested.Simulations were conducted on the condensed area of siro condensed spinning to optimize the selection of flow guiding device.The results showed that the three types of flow guiding devices could reduce the number of 3 mm hairiness,improve the yarn breaking tenacity,and have little effect on yarn evenness CV,but it could appropriately reduce yarn neps,thin places and thick places.Under the same negative pressure(1 000 Pa)condition,the yarn quality with and without the installation of the three types of flow guiding devices were compared.The flow guiding device I could reduce the number of 3 mm hairness by a maximum of 30.8%,increase the breaking tenacity of yarn by a maximum of 14.5%,the spinning effect was the best.By simulating the flow field,the numerical simulation results of three types of guide devices in the condensing area were compared.The simulated airflow velocity of using guide device I was the largest as 42 m/s,which had the best theoretical effect.It is considered that all the three types of flow guiding devices can reduce negative pressure while ensuring yarn quality,and flow guiding device I has the best application effect.关键词
