Effect of Seam Allowance of a Plain Seam on Bending of Woven Fabrics Available to Purchase

The present paper investigates the effect of real seams on fabric bending using Peirce’s fabric cantilever. The effect of a plain seam with different seam allowances and seam positions are discussed on bending of the fabric cantilever. Vertical and horizontal seams are studied experimentally in terms of bending length. Simple structured fabrics of plain and twill weaves with various fiber contents such as cotton, silk, wool and polyester are used. Theoretical study of a vertical seam on bending properties of woven fabrics are exhibited. Experimental bending behavior of vertical seam is explained using the second moment of area ofthe fabric cross section.
