Effect of Actual Overfeed Ratio on Natural Curvature of Overfed Seams

Abstract

In this paper, XIANGRONG XI and ISAO AJIKI define an actual overfeed ratio depending on the recovered length of an overfed seam. In particular, the effect of the actual overfeed ratio on the bending properties of the overfed seam was measured and the effect of fabric recovery on the fabric overfeed ratio was investigated. The results show that, for all samples, the natural curvature of an overfed seam increases proportionally as the actual overfeed ratio increase, which is different from the situation with the overfeed ratio. The two definitions of actual overfeed ratio and overfeed ratio can be connected by factor η, which is affected by stitch length, and by the recovery and compressive properties of fabric. The results also show that the factor provided the same varying tendency as the fabric recovery ratio, and that the differences between the factor and the recovery ratio depended on the kind of fabric involved.
