Investigating the effect of guide construction on yarn tension

Abstract

This article examines the influence of the movement of yarn formed inside the spinning chamber along its surface, as well as the influence of friction of the yarn on the inner surface of the yarn outlet funnel on the tension of the yarn on the smooth inner surface of the yarn outlet device. It has been established that at a rotation speed of the spinning chamber of 58000 rpm, when moving around the yarn formation axis, the quality of the yarn increases, unevenness decreases and the tension force increases. The article presents equations describing the yarn tension at the input and output of the yarn from the yarn outlet compactor at various speeds. Due to the use of compactors, additional twist is imparted to the radial part of the yarn located in the spinning chamber; it has been established that additional twist increases the strength of the forming yarn, makes the process more stable, and reduces the number of yarn breaks.
