Abstract
Abstract A highly conformable orthopedic bandage which exhibits a high "green strength" is provided for immobilizing or supporting parts of the body comprising a textile-like, apertured, porous, nonwoven polyester fabric of essentially unbonded, mechanically entangled fibers randomly entangled with each other in a pattern of localized entangled regions interconnected by fibers extending between adjacent entangled regions, impregnated with a settable composition.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
A highly conformable orthopedic bandage of improved green strength comprising: a textile-like, apertured, porous, nonwoven polyester fabric of essentially unbonded, mechanically entangled fibers randomly entangled with each other in a pattern of localized entangled regions interconnected by fibers extending between adjacent entangled regions and having a tensile strength of at least 1.0 pound per inch width of the fabric, an extent of elongation of from about 25 to about 100% in machine direction and of from about 40 to about 120% in cross direction of its relaxed length and width respectively, a fabric weight of from about 0.5 to about 3.0 ounces per square yard, a degree of openness defined by the presence of 50 to 500 apertures per square inch with an aperture size of from about 1/64 × 1/64 to about 1/8 × 1/8 inches; said fabric impregnated with a settable plaster of Paris composition.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
48 words
The orthopedic bandage of claim 1 wherein said plaster of Paris composition is coated onto said nonwoven polyester fabric from a slurry composition comprising plaster of Paris, and about 30 to about 85 parts by weight of water per 100 parts by weight of said plaster of Paris.
Claim 4
Dependent Claim
77 words
The orthopedic bandage of claim 1 wherein said fabric has a tensile strength of at least about 3 pounds per inch width, an extent of elongation of about 35 to 90% in machine direction and of about 40 to 110% in cross direction of its relaxed length and width respectively, a degree of openness of about 80 to 200 apertures per square inch with an aperture size of about 3/64 × 3/64 to 7/64 × 7/64 inches.
