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 of a slub, slub diameter increase, slub diameter, slub length and/or slub total mass. On evaluation, a measurement curve is produced from the values of the scanning, and an area (A(x)) between the measurement curve and a previously determined base yarn mass is computed. A permanent increase in the course of the area (A(x)) is used as a criterion for the presence of a slub. Slubs may be differentiated from yarn imperfections in a reliable manner by way of the area (A(x)).
