Abstract: Textile garments such as ladies'' hosiery and panty hose have improved stretch characteristics when knitted from bifilament yarns possessing a figure-eight-type cross section comprised of two prominent lobes connected by concave side portions of uniform symmetry. The particular geometry of these bifilaments causes preferential alignment at yarn crossing points whereby a random amount of twist is imparted to a knitted construction and entrapped between loop sections forming the network of the garments to enhance their stretch characteristics as compared to garments prepared from yarns having differently shaped cross sections.
