The present invention relates to packing for hermetically sealing a member. The packing in accordance with the present invention comprises knitting yarns each of which includes a plurality of longitudinally arranged reinforcing fiber yarns and expanded graphite integrally bonded to at least one side of the reinforcing fiber. yarns with adhesives. The knitting yarns are provided with excellent sealing properties and strong tensile strength and toughness. A plurality of such knitting yarns may be put together to form a core member. The core member may be covered, at the outer periphery, with a braided body of the knitting yarns. A plurality of such knitting yarns may be braided (square-knitted) or twisted. Thus, packing having a free length may be obtained. The packing thus obtained may be used cut, at a site, to a predetermined length according to the sizes of the object member to be sealed. This eliminates production, based on estimations in advance, of a variety of annular packing according to the sizes of object members to be sealed, as done in molded packing. |
