The Research on the Accuracy of the Geometrical Parameters of the Closed-Circuit Embroidery Element

The creation and application of embroidery systems in manufacturing the products of special purposes are rapidly expanding and requires a great accuracy of the elements. Both during the process of manufacturing and during the period of exploitation the shape of the embroidery element gets deformed and changes due to the impact of different mechanical forces. In the research, the form of five square elements of similar size but with different closed contour widths of 6 mm, 10 mm, 14 mm, 18 mm and 22 mm were analysed according to the characteristics of the materials affecting their performance. In the research there has been determined the inaccuracy of the whole width Fc and inner width FIc, different with respect to the threads of the structure of the fabric in all five closed-circuit square-shaped widths of the embroidery elements. The results of the research showed that irrespective of the width of the contour, the width of the embroidered element and the accuracy of the shape, in all cases, the direction of the fabric thread depends on the technological parameters of the process, and on the structure of the fabric, the operational, geometric properties depending on their characteristics.
