Abstract:

The value of twist is an essential yarn property for a spinner. This paper presents an analysis of the influence of changes in the yarn twist value on yarn tension and the stability of yarn formation conditions, including the balloon shape, while using a ring-spinning machine. In order to carry out this analysis, a computer program was used, which was designed on the basis of a mathematical model developed by the author of the dynamics of the twisting-andwinding unit. The results of numerical calculations are presented in the form of charts.

Tags: ring spinning machine, twisting-and-winding unit, yarn twist, yarn motion dynamics, mathematical model, numerical experiment.
