Abstract: According to the method for characterizing fancy yarn, at least one characteristic of the fancy yarn is scanned along the longitudinal direction of the fancy yarn. Values of the scanning are evaluated and the results of the evaluation are outputted. The results of the evaluation are the fancy yarn parameters such as base yarn mass, base yarn diameter, slub distance, mass increase (?M) of a slub, slub diameter increase, slub diameter, slub length (LE) and/or slub total mass. At least one result of the evaluation is outputted in the form of a graphic representation, for example as a scatter diagram. Such a graphic representation provides a clear representation of the measurement results. The occurring data is reduced and may be divided up into different categories.
