Abstract
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.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
120 words
A knitted structure comprised of successive courses and wales of false-twisted polyamide bifilament yarns of 7 to 30 deniers composed of prominent lobes having an intercept angle ranging from 10* to 54* circular peripheral surfaces connected together by concave side portions of uniform symmetry to form a figureeight cross section configuration, said lobes having surfaces of curvature no greater than the surface curvature of said concave side portions, said yarns being aligned at yarn crossing points so that a lobe portion of one yarn rests against a concave side portion of an adjacent yarn whereby twist is entrapped between loop sections forming the course and wale construction network of the knitted structure thereby enhancing the stretch characteristics of said structure.
