Abstract
A sorbent glass fiber material is useful for sorbing spills of water and water-soluble liquids. The sorbent material includes glass fibers combined with hydrophilic absorbent particles. The particles may be made from polymers having hydrophilic groups such as crosslinked polyacrylamide, crosslinked sulfonated polystyrene, crosslinked polyacrylate, crosslinked polymethacrylates, crosslinked copolymers of acrylates and methacrylates, and mixtures thereof. The glass fibers may be bindered (e.g., batting insulation) or unbindered (e.g., loose-fill blown wool insulation).
