  • Oil absorbent layered fabric sheet
    Patent number: 5156743
    Abstract: A method for removing oil from the surface of a body of water using a layered sheet comprised of natural fabric fibers to absorb oil between the layers in the sheet, the natural fabric fibers in the sheet not requiring or undergoing treatment by or with synthetic chemical compositions during formation of the layered sheet. The layered sheet absorbs at least seven times its weight in oil without submerging in water. The layered sheet is placed on the floating oil which is absorbed by the sheet. The sheet is later removed from the water surface and compressed to squeeze oil from between the layers of the sheet.
