Abstract
In order to investigate the asymmetry in structure and properties of fabrics in the direction of the right and left 45° bias with respect to the warp, shingohsen twill weave and rayon plain weave were used. These two kinds of the bias samples for each fabrics were examined by the observation of scanning electron microscope photographs, microscope photographs, load-elongation curves and extension in length of circular flare skirts. The shape changes by extension, load-elongation curves and extension in length of circular flare skirts of two kinds of the bias samples were very different each other. These results show that the samples in the directions of the right and left 45° bias directions are asymmetrical with respect to the warp. The difference of two kinds of the bias samples for shingohsen and rayon materials both were seen due to the structure of the twist of the weaving threads and/or the textile weaves.
