Abstract: A low density fabric substrate for a medical bandaging product. The substrate has a plurality of longitudinally-extending voids formed in the fabric for permitting water penetration through the fabric thickness from one of the major faces to the other major faces. A reactive system is impregnated into or coated onto the substrate and remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to sufficient moisture to form a rigid, self supporting structure. A soft, flexible protective material covers at least one of the major faces of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the material is in use.

Abstract: A medical bandaging product, including a sleeve formed of moisture-impervious material and sealable to prevent entry of moisture, and a medical material positioned in the sleeve and sealed therein against entry of moisture until use. The medical material is a substrate having two marginal areas of relatively lower modulus yarns and/or a more open knitted structure to provide reduced abrasion against the skin. A reactive system on the substrate remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to sufficient moisture to form a rigid, self supporting structure. A soft, flexible protective material covers at least one of the major faces of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the material is in use.

Abstract: There is provided a testing device for testing the seam of a garment that includes a mechanical abrader frame holding elongate members and a control unit. The mechanically oscillating elongate members are each connected to an actuator located within the frame. A test sample is placed on the elongate members of the mechanical abrader frame. Actuators are attached to the connection rods that extend through openings in the front wall of the frame and attach to each of the elongate members for imparting extending and retracting movement to the elongate member. Each of the actuators has an attachment member affixed to its rear end that permits a support rod to pass therethrough allowing for a degree of rotation about the support rod as the connection rod is extended and retracted. A control unit regulates movement of the elongate members and determines the number of revolutions of the elongate members. A method for testing the seam abrasion of a garment seam is also provided.

Abstract: A cast tape or medical bandaging product formed from a resin-coated or impregnated fabric material that includes a knitted substrate having a combination of non-fiberglass high and low tenacity yarns such as polypropylene, polyester and elastomer. The polypropylene and polyester yarns have a high number of filaments, typically 48 to 90 filaments. This significantly improves the surface area of the fabric, that helps help to hold the curable resin onto the fabric and avoids pooling. This in turn improves lamination layer-to-layer and gives the substrate high strength.
