Yarn tension is a phenomenon of fundamental importance for rotor yarn formation. The problem of dynamic tensions during spinning is of essential importance, as it may result in the possible decrease in yarn quality parameters, such as irregularity of linear density, elongation, tenacity, and the number of faults. We analysed the parameter dependencies which characterise sliver feeding the spinning machine, as well as the dependencies of linear density of the product manufactured on the tension which appears during the process of rotor spinning. This research fragment, on the basis of which the influence of the yarn's linear density on the tension estimated, is discussed in this paper. The measuring method and equipment used is presented.
