ABSTRACT:
For both orthopedic and sports uses, a foamed plastic pad is integrally molded to a fabric. More particularly, a knitted sleeve is constructed having a terry loop on the interior surface of a hydrophobic yarn (e.g. acrylic) and an exterior surface of a hydrophilic yarn (e.g. cotton), whereby moisture is wicked away from the surface in a hydrokinetic fashion. A soft, hydrophilic polyurethane foam pad, which acts as a sponge, absorbs the moisture, is molded integrally with the sleeve, leaving the terry loops free for skin contact. For sports uses, knitted or woven fabrics may be employed, and stiffer, polyurethane foams are preferred.
