Patent ID: 7465283

Claim:
A cast or support assembly comprising: a compressible padding layer including a padding material formed of double knit type fabric material having an inner layer of finely woven or knit material with openings defining a smooth surface structure, and an outer layer of coarsely woven or knit material with openings therethrough spaced from said inner layer by an open work matrix of filaments which are integrally woven or knit into said inner and said outer layers of woven or knit material, the outer layer openings being larger than the openings of the inner layer, the padding layer being devoid of a hardening material such that the padding layer remains compressible upon exposure to water; and a hardenable layer including an outer water hardenable double knit type material overlying said padding material, said outer double knit material being impregnated with water activatable hardening material to provide the desired immobilization; wherein the matrix of filaments are formed from wicking yarns to facilitate moisture transfer from the inner layer to the outer layer; whereby the spacing between layers of said padding material in addition to the holes therethrough, facilitate air circulation to accomplish rapid drying of the cast assembly.
