  • Patent number: 4535016
    Abstract: An insulating material for an insulated article and a method for making same are provided. The article comprises goose down or similar insulation, together with an excess of submicron finely divided hydrophobic particulate metal or metalloid oxide pigment contained in an envelope. The envelope is tightly woven (or similar) fabric which is permeable to gas, but retains the pigment. An envelope having good breathability and, hence, dryability is provided together with improved insulation and resistence to water penetration and absorption. In addition, the envelope may be compressed when not in use and still recover its loft thereafter when the pressure is released.
