Key importance and the role of sewn seam in the woven fabric are presented. Fabric properties in the places joined with the sewn seam on which garment durability, applicability, appearance and quality depend are highlighted. Seam location is usually the weakest spot on the garment, especially when the great loads are present at these places. Mechanical properties of the sewn fabrics were investigated in different test conditions. The influence of the load on the sewn seam is analyzed in time intervals. Sample with seam have approximately 70% lower breaking properties (breaking force and elongation at break) than the sample without seam. By preloading the seam fabrics with 30%, 50% and 70% of elongation at break, for a 3-h period, the effect on mechanical properties were tested and the differences in pre-stretching intensity were observed. By conducting such test, it is expected that the fabric experience further degradation and that breaking properties further reduce, but the exact opposite occurred (breaking properties, by increasing the preload, increase even more), because of various material properties (structural fabric properties, raw material characteristics, seam characteristics).


The weaving process is constantly evolving in terms of productivity, quality, and possibilities of fabrication of different fabric structures and shapes. This article covers some issues that have still not been resolved and represents distracting factors in the woven fabrics production. In the development of woven fabric using the CAD technology, it is inevitably a deviation of the virtual image on the computer screen from the woven sample. According to comprehensive industry analyses, the findings of many authors who contributed to the resolution of these problems can be concluded that these problems are still present in the development and production of striped, checkered, and jacquard woven fabrics. In this article, jacquard, multicolor woven fabrics were investigated, with deviations in pattern sizes and shades of color in warp and weft systems compared to virtual simulation on the computer, as well as the tendency of the weft distortion arising from the weaving process leading to the pattern deformation.
