Abstract
Skewness in woven fabric results when filling yarns are displaced from a line perpendicular to warp yarns. Effects of skewness on drape of four-gore skirts, the level at which skewness becomes excessive, and the relationship of shear hysteresis to skewness were investigated Skirts were made from fabric a manufacturer supplied with near zero skewness and with four varying levels of induced skewness. The drape profile of skirts, worn by a manikin suspended from the ceiling, was photographed. Plexiglass, with quadrant lines and two holes for the manikin legs, was positioned at the bottom of the skirt. Slides were projected onto a viewing screen interfaced to a digitizer and computer. Digitized data included area of the profile, distance from the apex of nodes to the intersection of the quadrant lines, distance between apexes of adjacent nodes, and area of asymmetry between the right and left sides. Differences were significant for distance between apexes of adjacent nodes and for asymmetry. All skewness levels were excessive for distance between adjacent nodes and 4.4% for asymmetry. Linearity was significant for both variables. Pearson's correlation between shear recovery in the filling direction and the levels of skewness was -0.8527.
