ABSTRACT
Sliding stitches represented by removing seam elements under the action of a load, displacement caused by the removal of material assembled edges. This phenomenon may occur during the product behavior, causing an aesthetically unpleasant. Dragging causes of concern:The type and characteristics of the materials assembled by stitching: a use for the realization of the assembly materials of wires with a very low coefficient of friction to facilitate its movement to the starting position; a degree of complexity of the structure of materials assembled directly influence the phenomenon of sliding as the structure is simple, the more risk there will be movement into seam yarns; a density material also has an influence on the slides forward - low density material will slide easier in stitching.The technological process of sewing. Parameters of the sewing operation have direct and significant influence on the phenomenon of sliding stitching: a stitch type - the stitching is more rigid, the greater risk of developing slides forward; a stitch density - a density as high as possible to allow better establishment of yarn materials, given an approximation as possible of the ideal situation, the pace is so small that each strand of material is trapped into the mesh stitching individually.Using a higher value for the sewing needle thread tension reduces the risk of sliding materials with the into seam.
