Analysis of bending and drape properties of seamed fabrics

This paper investigated the change of fabric bending performance of different seams,with focuses on the change of drape with different seam type,widths and related causes.The results showed that the bending length and bending rigidity at the seam obviously increased compared with the original fabric;some main drape parameters of the samples with radial or circular edge seams were greater than those of un-sewn samples,such as drape coefficient,average radius,stiffness index and so on;and as to sample with radial seams,the drape coefficient was influenced by the seam width,seam position,seam′s bending length and rigidity.The study has offered some guidance for the evaluation of seamed fabrics as well as garment shape and simulation.
