Abstract
An elastomeric nonwoven absorbent web is provided. The web comprises a nonwoven fibrous matrix of elastomeric melt-blown small diameter fibers and absorbent staple fibers or absorbent particulate material, wicking staple fibers, and bulking staple fibers dispersed throughout the matrix. This web is particularly useful in an absorbent elastomeric wound dressing. The wound dressing has a fluid permeable, compliant, low adherency wound contacting layer, an intermediate conformable, fluid-absorbent element, i.e., the elastomeric nonwoven absorbent web, and a soft, compliant cover layer.
