Hydrophilic polyurethane structures and methods of using the same

Abstract

Fiber supports include a base and hydrophilic polyurethane foam that directly contacts the fibers while being elastic and flexible for reshaping. Hydrophilic polyurethane foam has a density to hold over nineteen times its weight in liquids that absorb into the fibers in direct contact with the foam over time. Supports may be any shape or size, and may be rigid or flexible. Cylindrical shapes are useable to permit winding, curling, or spiraling of fibers about the support. The fibers are directly affixed to the foam for support and shaping. A clasp may be clamped or snapped over the fibers and foam support to compress the two directly together. If the support is flexible, the foam may be reshaped with the fibers, holding the shape during wearing or drying. During such wearing or drying, liquid held in the foam may be absorbed directly into the fiber, resulting in favorable chemical treatment.
