  • Patent number: 4172456
    Abstract: A full-length, anti-embolism stocking extends over a wearer's leg and is adapted to exhibit a controlled, graduated compressive force on the leg. The compressive force is greatest in the ankle area and diminishes over the length of the stocking to a minimum at the top. Three distinct and defined sections make up the stocking, a lower section covering the calf and foot has a one-way stretch in a circumferential direction, an upper section covering the thigh also has a one-way stretch in a circumferential direction, and an intermediate section covering the knee has a two-way stretch. The knee and calf-foot sections comprise a fabric formed with a jersey stitch incorporating an elastomeric yarn. In the knee section the elastomeric yarn is knit-in to provide the two-way stretch and in the calf-foot section it is laid-in to provide only a one-way, circumferential stretch.
