采用Matlab程序模拟纤维的运动轨迹,研究了网格圈型紧密纺纱系统吸气负压和网格圈外表面摩擦系数对集聚区纤维集聚效果的影响,比较了网格圈紧密纺纱和常规纺纱的成纱质量.结果表明:吸气负压为2 350 Pa,网格圈外表面摩擦系数为0.6时,紧密纺纱系统集聚区纤维的集聚效果较好,纤维的快速集聚和调整集聚时间短,出现较长时间的稳定集聚状态,纤维能够被集聚区气流有效地控制;与常规纱线比较,紧密纺纱线强力提高16.51%,纱线USTER条干提高5.7%,毛羽减少58.37%.

Fiber trajectory was simulated by Matlab software,effects of inspiratory negative pressure of lattice apron type compact spinning system and different friction coefficient in outer surface of lattice apron on effects of band effect in zone accumulation were researched,and its yarn quality was compared with that of regular spinning.The resulted showed that when negative pressure was 2 350Pa,friction coefficient of lattice apron was 0.6 fibre accumulated rapidly and accumulation-adjusting time was short;the period of steady accumulation was extended;fibre accumulation could be effectively controlled by airflow in accumulation zone. By using compact spinning technology,strength of the yarn increased by 16.5% evenness of yarn USTER increased by 5.7%,filoplume reduced by 58.37% compared with normal yarn.
