We present here an analysis of the stages of static tearing in cotton fabrics for wing-shaped test specimens. For the analysis and measurements of geometry of the tearing zone, a program for image analysis was realized and video film elaborated. Moreover, the influence of the constructional features of woven fabrics and fabric structure, and also the testing conditions on the tear force and tearing zone parameters were examined.
