Drape is a unique property that allows a fabric to be bent in more than one
direction with double curvature. For many years, textile researchers studi
ed this attribute in order to evaluate the drape quality and improve the dr
ape appearance of garments. However, fabric drape can be more realistically
investigated by considering seams. At present, research in this area is ve
ry limited. This paper presents a fundamental drape analysis of seamed fabr
ics using Cusick's drapemeter. Simple plain and twill woven fabrics with va
rious fiber contents of cotton, linen, silk, wool, and polyester are given
radial and circular seams. The effects of seam allowance and seam position
are investigated experimentally. Drape behavior is determined and compared
in terms of drape coefficient, node analysis, and drape profile. Investigat
ing drape on seamed fabrics can improve apparel design and fabric end-use a
pplications. Moreover, it contributes to garment drape prediction for the c
lothing CAD system.
