转杯纺假捻盘捻陷作用分析

Analysis of twist fault of navel in rotor spinning

因关于转杯纺假捻盘的阻捻及捻陷作用的研究尚存争议,为此,在分析转杯纺假捻盘两段纱条的运动以及建立加捻区的捻度变化模型的基础上,对假捻盘的阻捻及捻陷作用进行系统地研究。首先,定义了纱条的公转运动以及自转运动的概念,经分析认为假捻盘存在捻陷作用,但不存在阻捻作用。之后,制作了实验装置,采用模拟实验的方法进一步研究了假捻盘的捻陷作用,得到了捻陷作用发生时纱条的捻度传递曲线。研究结果表明,随着纱条张力的增大,捻陷作用不易发生。

It doesn＇t reach any agreement about the research of twist fault and twist deterrent of navel in rotor spinning. On the basis of the motion analysis of both ends yarns of the navel and the model building of twist fault and twist deterrent. Firstly, two concepts about revolution motion and spinning motion of yarn are defined, then it deny the twist deterrent and determine the twist fault. Finally, it adopt the simulation experiment to study the twist fault of the navel by making experiment device, and get the twist transfer curve as the twist fault occurs and the conclusion that twist fault is less likely to appear with the increase of yarn＇s tension.
