Abstract
In this series of articles, the sewing feeding force and its regularity which is an indicator to stitch size regularity were measured using two different computer–based measuring systems under the real conditions of sewing process. The first system is an indirect method based on measuring the electric power consumption due to fabric feeding. The second system was established to measure the feeding force directly using a gauge piece and a strain meter. The effect of sewing machine parameters in terms of speed, presser foot pressure and stitch size on the feeding force and its regularity from stitch to another were studied. The effect of sewing parameters in terms of number of fabric layers and sewing line direction were also studied. The effect of sewing machine parameters on the shear distance between fabric layers and the relation between feeding force regularity and stitch length regularity were investigated. The established computer based measuring system could be used as a testing instrument to identify the different ideal sewing parameters for different kinds of fabrics in order to control the sewing quality.
