Abstract
Abstract Disclosed is a waterproof, moisture-breathable, non-macerating and hypoallergenic fabric including a moisture-absorbent, non-macerating hypoallergenic substrate formed from natural or synthetic fibers, the moisture absorbency of the substrate being provided by the inherent moisture absorbency of the fiber selected and the attractive capillarity of the formed substrate. An acrylic polymer basecoat is coated onto said substrate. The basecoat has sufficient viscosity when applied to prevent strikethrough when the basecoat is applied to the substrate. A topcoat is selected from the group consisting of polyether urethane and silicone latex and is coated onto the basecoat.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
A waterproof, moisture-breathable, and hypoallergenic fabric comprising: a moisture-absorbent, non-macerating hypoallergenic substrate formed from natural or synthetic fibers, the moisture absorbency of said substrate being provided by the inherent moisture absorbency of the fiber selected and the attractive capillarity of the formed substrate; an acrylic polymer basecoat coated onto said substrate, said basecoat having sufficient viscosity when applied to prevent strikethrough when said basecoat is applied to said substrate; and a topcoat selected from the group consisting of polyether urethane and silicone latex coated onto said basecoat, whereby said fabric can maintain prolonged direct contact with skin without causing maceration.
Claim 2
Dependent Claim
