Abstract

A cloth weft densitometer has been proposed and its propriety verified by a preliminary experiment. The method is based on the counting of cloth wefts by a CCD camera with a shutter speed of 1 ms. The experiment shows that the densitometer can be used perfectly for many types of cloth if the cloth speed of less than approximately 10 m/min. The accuracy of the cloth-weft counting is above 99%, provided that the image contrast of the weft on the CCD camera is sufficiently high. Only 2-step digitation by the A/D converter is needed for 99% accuracy.
