A yarn of exfoliated graphite as a base material that is improved so as to have enriched flexibility free from any stick-out of exfoliated graphite at ordinary bending processing, thereby avoiding any partial loss of exfoliated graphite at twisting or braiding operation for preparing of a gland packing. Yarn (1) for gland packing is produced by filling the interior of tubular member (3) obtained by knitting or folding Inconel wire (2) of 0.1 mm diameter with fibrous exfoliated graphite (4) being in the form of a fiber with a cross section set so as to exhibit an aspect ratio, being a quotient of width (w) divided by thickness (t), of 1 to 5. |
