Abstract
A packing for hermetically sealing a member. The packing in accordance with the present invention comprises braiding 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, so that the braiding yarns are provided with excellent sealing properties and strong tensile strength and toughness. A plurality of such braiding yarns may be put together to form a core member. The core member may be covered, at the outer periphery thereof, with a braided body of the braiding yarns. A plurality of such braiding yarns as put together may be braided (square-knitted). Alternatively, a plurality of such braiding yarns (4) as put together may be twisted. Thus, packing having a free length may be obtained. The packing thus obtained may be used as cut, at a site, to a predetermined length according to the size of the object member to be sealed. This eliminates production, based on estimations in advance, of a variety of annular packings according to the sizes of object members to be sealed, as done in molded packing.
