摘要： The present invention provides protective goods, for example arctic clothing which allows long-time working even under the low temperature environment; said protective goods being characterized by excellent workability, heat-insulation and anti-static feature, without being hardened and embrittled, especially at the temperature of -10 degrees Celsius or below, further, under the environment of very low temperature such levels as -30 degrees Celsius or -60 degrees Celsius, furthermore even under the environment of extremely-low temperature on the level of -100 to -250 degrees Celsius. Protective goods made from a multiple-layer composite cloth, where the composite cloth comprises a surface fabric, an intermediate fibrous-insulator and a lining fabric, mainly composed of aramid fiber, respectively, wherein 1) the surface fabric and the lining fabric, comprises meta-aramid fiber by weight of 50 to 100 percent, para-aramid fiber by weight of 0 to 10 percent and other flame-retardant fiber by weight of 0 to 40 percent, with provision that the total weight-percent of meta-aramid fiber, para-aramid fiber and other flame-retardant fiber, is 100; 2) the intermediate fibrous-insulator comprises a multiple-laminated felt made from aramid fiber; and 3) electro-conductive yarns (a) are arranged along the lengthwise direction of the surface fabric at a density of 1 to 5 per inch and additional electro-conductive yarns and/or tapes (b) are arranged along the direction intersecting the lengthwise direction to form contact points with the electro-conductive yarns (a), whereby triboelectric charge on the outside surface of the protective goods is less than 0.6 micro-coulomb/m2.
