  • Patent number: 5626556
    Abstract: The invention concerns how the loop portion of a VELCRO fastener can be RF welded to a compression sleeve or other similar article. By using a simpler two-step method, in which the loop portion is provided with a backing laminated thereto, both labor and material costs have been reduced over the prior art five-step method.

  • Patent number: 4515594
    Abstract: An improved surgical dressing or surgical sponge being a composite nonwoven and knitted fabric structure having high fluid absorbency and capillarity characteristics, is prepared by knitting a set of chain stitch wales of hydrophilic yarns, with said chain stitch wales being interconnected laterally by sets of filling courses, said filling course yarns being also comprised preferably of hydrophilic material. The chain stitch wale yarns are interknit through a light-weight, absorbent, non-woven web. The centrally disposed non-woven web is pliable and deformable so that capillary fibrous bundles of non-woven fabrics may be drawn into intimate physical contact with the yarns forming the loops of the chain stitch wales and their associated filling courses, resulting in a composite material having enhanced absorbancy and capillarity characteristics.

  • Patent number: 4173131
    Abstract: A lightweight, porous knitted elastic bandage is produced from a warp of false-twist synthetic yarns with a filling inlay of regular yarns. The filling yarns are arranged in varying patterns across the warp yarns so that a portion of their length lies in looped and cursive configuration upon the surface of the bandage, and the structure is so open that overlapping layers of the bandage cling to each other in substantially non-displaceable relationship.

  • Patent number: 4027667
    Abstract: A therapeutic stocking comprising, a circumferentially elastic boot portion having an upper thigh panel for exerting a desired compressive pressure against the upper thigh of a wearer's leg. The upper thigh panel has a limited vertical stretch relative a hip panel for accurate placement of the upper thigh panel on the wearer's upper thigh. The stocking has waist support means, and the hip panel extends between the support means and the upper thigh panel along the side of the wearer's hip. The hip panel is vertically stretchable between the support means and the upper thigh panel to permit placement of the support means on the wearer's waist a variable distance from the upper thigh while the upper thigh panel remains at its proper position on the wearer's upper thigh.
