Annotation:

The application and development of electrically conductive embroidery systems is closely associated with the development of smart textile technologies. The latest smart embroidery systems are able to receive cell signals, control health status, warn at risk, etc. The formation of defects in embroidery systems is a problem faced during the technological processes, when textile materials are mechanically exposed to pressing, crushing, stretching and etc. Precision, reliability, appearance, wear properties and functionality of embroidered elements have a significant influence on the high qualitative requirements. The aim of the work to investigate and assess the influence of fabric structure on the quality and functionality of embroidery elements.

The thesis provides research on the accuracy of geometrical parameters of closed-circuit embroidery elements, taking into account the fabric properties and technological parameters of the process. In addition, an assessment of the uncertainty of method of the analysis of geometric parameters of embroidery elements is included. The thesis also provides research and analysis of the influence of technological parameters of the embroidery process on electrical conductivity of the embroidery element. The influence of speed of the embroidery process on the quality of embroidery elements was also assessed. The study includes research and analysis of the influence of exploitation factors on conductivity and geometrical parameters of the electrically conductive embroidery element.
