Bending behavior of woven fabrics with vertical seams

This paper presents a study of the bending properties of fabric strips with vertical plain seam. The "second moment of area" of a seamed cross section determines the bending behavior of such a strip. Fabric thickness, seam th ickness, distance of the neutral axis from the surface of the cross section , and seam allowance width are involved. Various woven fabrics with differe nt seam allowances are investigated. Bending length and bending rigidity ob tained from the experimental results are highly related to the second momen t of area of the seamed fabric cross section.
