Abstract [eng] Embroidered design element is designed to achieve the desired result for the evaluation, embroidery thread, embroidered material properties, the possibilities of embroidery machines and tools. Therefore, it is important to emphasize that there are no embroidery parameters set suitable for all the cases. In this thesis, the blue polyurethane coated polyester knitted fabric was selected which is embroidered using the same design of embroidery but changing different technological parameters and types of embroidery threads. This research also focuses on how non-standard embroidery threads could by affecting the quality of embroidered element by using the same technological parameters. Carried subjective quality evaluation as well as the measured geometric parameters of actual embroidered element are compared with the program designed element dimensions. There were identified the differences between embroidered element and initial thickness of the material, mechanical behavior of the embroidered elements is analyzed under uniaxial tension characteristics (breaking force and elongation at break). The optimal set of embroidery technological parameters was set and is considered as being suitable for increased functionality fluorescent and metallic embroidery threads which can also be applied to clothing. The paper showed that different embroidery technological parameters such as filling type (Tatami and Satin) and adaptation of different stitch densities affects geometrical and mechanical properties of the embroidered element. During embroidery process the base material is damaged and thus changes of the strength and the thickness of embroidered area increases. It was indicated that even if supporting tools (such as stabilizing non-woven material and pull compensation) are used, the differences between embroidered and designed elements are difficult to avoid. Plus, the studies have shown that the choice of different embroidery thread, even with the same set of technological parameters, affects not only the appearance of embroidered element but also might affect investigated mechanical properties. Based on the results of the research and the embroidered design element, there are offered some opportunities and ideas by using embroidery method for apparel products in the collection. The research methodology to collect data is placed on the scientific article titled “Comprehensive analysis of the quality of coated fabric embroidery” (Annex 3), for the scientific magazine “Fibers and Polymers” which is now being reviewed.
