Abstract: A sealing material composition which comprises sheet-like members containing expanded graphite, and which hardly causes the sheet-like members to be broken is provided. A sealing material composition 1 comprises: a stacked body 5; and a long surrounding body 6 which surrounds the stacked body. The stacked body has a plurality of sheet-like members 10 each of which is formed into a tape-like shape by expanded graphite. In the stacked body, the plurality of sheet-like members are stacked in a direction which intersects with the longitudinal direction of the surrounding body, and, in the plurality of sheet-like members, sheet-like members which are adjacent to each other in the stacking direction are disposed to be displaced from each other in the longitudinal direction of the surrounding body, in a relatively movable manner.

Abstract: In order to manufacture a yarn in which filler materials are loaded into a tubular member, the method of manufacturing a yarn has a step of knitting a wire material to form the tubular member. In the step of knitting the wire material, knitting of the wire material is advanced by a plurality of knitting needles, which are placed substantially concentrically about a rotation axis, while revolvingly moving the knitting needles about the rotation axis. When a stitch is to be formed by the wire material, the wire material is prepared so that an arcuate loop portion, which defines a part of the external shape of the stitch, is expanded in a direction which, in a state where the tubular member is developed, is inclined with respect to a straight line that extends in the axial direction of the tubular member.

Abstract: A yarn in which slipping of filler materials from a tubular member can be reduced while suppressing the manufacturing cost is provided. The yarn has a tubular member, and a plurality of filler materials that are formed into a strip-like shape, and is configured by loading the filler materials into the tubular member in a state where the longitudinal directions of the filler materials are made extending along the axial direction of the tubular member. In the yarn, the tubular member is configured by using wire material that is knitted so as to produce stitches. The wire material has arcuate loop portions that define parts of external shapes of the stitches. In a state where the tubular member is developed, the loop portions are expanded in a direction that is inclined with respect to a straight line that extends in the axial direction of the tubular member.

Abstract: A gland packing provided in a fluid apparatus such as a pump and compressed in an axial direction so as to prevent penetration leakage of a fluid is provided. The gland packing has a packing base material 11 of a predetermined length including a band-like flat braid 12 braided by moving a plurality of yarns 13 along one track K. The band-like packing base material 11 is shaped into a ring by abutting longitudinal ends 12a and 12b of the packing base material 11 so that a width direction thereof is parallel with a packing axial direction, and is then compressed in the axial direction, whereby the packing base material 11 is overlappedly folded in a packing axial direction, with a longitudinal direction of the packing base material 11 as a direction of folding lines 14.
