ABSTRACT:
A method of recognizing particle impurities in textile material includes the following steps: forming a thin fiber web; detecting each particle impurity by an electron-optical sensor; applying signals from the sensor to an image processing system; determining a specific characteristic for each particle impurity by an evaluating device forming part of the image processing system; classifying the particle impurities based on the specific characteristic by comparison with reference data; and counting the particle impurities.
