Impact of Vertical and Horizontal Forces on the Seam in the Technological Process of Sewing Knit Fabrics

Abstract The aim of this study was to determine the increase in vertical and horizontal forces of the presser foot on the seam during the technological process of sewing knit fabrics. The research was performed on three types of knit fabrics: double jersey (rib one plus one), interlock knit fabric, and bleached interlock knit fabric. In order to meet the criterion of seam quality, it is necessary to adjust the above-mentioned parameters optimally. Depending on the type of the knit fabric, the values of the investigated forces change, and by increasing the number of layers and the sewing speed, the force values increase.
