In order to understand quantitatively the loss phenomena in the width of sewn fabrics, the relations between the loss in the width of sewn fabrics and each of the thickness of threads, the thickness of fabrics and the seam finishes were investigated by using various man-made leathers and polyester threads of different thickness. (1) In the relation between the thickness of the thread and the loss in the width of the sewn fabric, the thicker the thread, the larger the loss. (2) The loss in the width of the sewn fabric of welt seam is larger than that of open seam. (3) The thicker the fabric, the larger the loss in the width of the sewn fabric. Furthermore, there are high correlations between the thickness of fabrics and the loss in the width of sewn fabrics. (4) In the schematic models of the loss in the width of sewn fabrics, the theoretical loss in the width of the sewn fabric D can be approximately expressed as, D=(π-2)t+πα or D=πt+πα where t is the thickness of fabrics, α is the swelling in the area of the seam and is associated with the thickness of thread and the stitch density. As above mentioned, from the experimental and theoretical view points, it is made clear that the loss phenomena in the width of sewn fabrics is related to the fabric thickness, the thickness of the thread, the stitch density and the method of seam finishes.
