    • 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.
    • 提供绝缘物品的绝缘材料及其制造方法。 该制品包括鹅绒或类似的绝缘,以及包含在包封中的过量的亚微米细分散的疏水性颗粒金属或类金属氧化物颜料。 信封是密封的(或类似的)织物,其可渗透气体,但保留颜料。 提供具有良好透气性,因此具有干燥性的包膜,同时具有改善的绝缘性和耐水渗透性和吸收性。 此外,当不使用时,信封可能被压缩,并且此后当释放压力时仍然恢复其放样。
