Static tear strength is one of the most important criteria of strength property assessment of many textile groups. Taking into account the significance of this criterion, research on possibilities of theoretical prediction of fabric tear strength is carried out. Problem of tearing strength is very complex, because according to the literature and research done so far, the tear force depends on many factors, i.e., parameters of threads, fabric structure, as well as force distribution and geometrical relationships taking place in so called tearing zone. In presented paper a trial of detailed description of events in cotton fabric tearing zone with taking into consideration the geometry of tearing zone was undertaken. Firstly, research on designing and building of stand for registration and computer image analysis was undertaken, moreover the methodology of a proper registration and analysis of obtained tearing images, and then quality and quantity assessment of events is the tearing zone was establish. Experiment was carried out for model cotton fabrics of such a structure, which enables observations of changes during tearing one set of threads at the assumption than the parametrers of another set of threads are unchangeable. There are presented results concering the effectiveness of image analysis system for assessment of static tearing in fabrics, description of static phases, characteristic parameters of tearing zone and analysis of geometry of tearing zone, as well as influence of parameters of cotton fabric structure, and parameters of tearing zone.
