Abstract
A knitted therapeutic medical compression stocking made from courses of bi-component fibers inlaid courses of spandex yarn. The use of bi-component yarns, in particular, crimped yarns having an elastomeric core preferably of a polyurethane and a thermoplastic sheath preferably of a polyamide when knit with inlaid courses of bare spandex, covered spandex, or spandex covered with a bi-component yarn forms therapeutic medical stockings that provide excellent compression control. In addition, these therapeutic stockings are more transparent than conventional therapeutic stockings. The therapeutic stockings of the present invention may be knit on a conventional circular hosiery knitting machine.
