    • PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding coating material having light weight, proper extendibility and durability.
      SOLUTION: A first yarn member (10) is formed by bundling 48 polyester fibers and spirally winding a metal foil 12, obtained by tin-plating a copper foil. A second yarn member (20) is obtained by bundling 96 polyester fibers of the same as the previous fibers. Doubled yarns (10A, 10B, 10C, and 10D) obtained by doubling the two first yarn members of a first direction directed from an upper right toward a lower left, doubled yarns (20A, 20B, 20C and 20D), obtained by doubling the two second yarn members 20 of the first direction, doubled yarns (10a, 10b, 10c and 10d) obtained by doubling the two first yarn members of a second direction directed from an upper left toward a lower right, and doubled yarns (20a, 20b, 20c and 20d) obtained by doubling the two second yarn members of the first direction are crossed with each other so that when the doubled yarns of other direction crossed each other, with one doubled yarn of one direction being disposed at a position of two lower sides, the doubled yarns are then disposed at two upper sides.

    • 要解决的问题:提供具有重量轻,适当的可扩展性和耐久性的电磁波屏蔽涂层材料。 解决方案:第一纱线部件(10)通过捆扎48个聚酯纤维并螺旋卷绕金属箔12形成,该金属箔12是通过镀铜箔获得的。 通过将与以前的纤维相同的96个聚酯纤维捆扎而获得第二纱线部件(20)。 通过将两个第一纱线部件从右上方向左下方加倍的双重纱线(10A,10B,10C,10D),将纱线(20A,20B,20C和20D)倍增, 第一方向的两个第二纱线部件20,通过将两个第一纱线部件从左上方向右下方加倍而获得的双倍纱线(10a,10b,10c和10d)和双纱线(20a,20b) ,20c和20d)通过使第一方向的两个第二纱线部件加倍而彼此交叉,使得当另一方向的双股纱彼此交叉时,一个方向的一根双纱布置在两个下方的位置 然后将两倍的纱线设置在两个上侧。
