Abstract
The invention relates to a method and a device for evaluating the quality of a yarn ( ). In order that further aspects of the quality of a yarn may be taken into consideration and explained by measured values so that the quality of a yarn is as a whole substantially detectable, measured values relating on the one hand to the yarn exposed to friction and on the other hand to the yarn not exposed to friction are to be derived from the yarn. Both measured values are used to form a further measured value which represents a further qualitative feature.
