Investigation of Open End Yarn Tension Using an Elastic Yarn-Guide

Abstract

This paper presents the results of Open End (OE) yarn tension investigation using a yarn-guide funnel with an elastic element. Obtained were the dependencies of tension change on such factors as body mass, elastic element rigidity, yarn coordinates on the funnel surface, and the speed of yarn moving. The values of these factors cause fluctuations in yarn tension and, consequently, in yarn structure and characteristics. On the basis of experiments, it was shown that due to using of a yarn-guide funnel with an elastic element, a decrease in yarn unevenness is achieved. It is easily regulated by the funnel mass, the rigidity rate of the elastic element, and the spinning speed.
