This invention relates to a packing for sealing the joint between members. Expansive graphite (41) is bonded integrally to at least one of the surfaces of a plurality of reinforcing fiber yarns (40) disposed in a longitudinal direction by an adhesive to constitute knitted yarns (4) having high sealability, high tensile strength and high toughness. A plurality of such yarns (4) are bundled to form a core (2) and the outer periphery of the core (2) is covered with a knit assembly (3) of the knitted yarns (2), a plurality of knitted yarns (2) are bundled and knitted (square knitting), or a plurality of knitted yarns (2) are bundled and twist knitted so as to obtain a packing of a free length. Since this packing can be used by cutting in to a required length on site in accordance with the dimension of the member, it is no longer necessary to produce, based on a forecast, a variety of annular packings in accordance with the dimensions of members, unlike in the case of preformed packings. |
