Abstract

PURPOSE: To provide a gland packing whose lubricating property and sealing ability are stably retained for a long period, by impregnating a filler containing a specified percent by weight of a hydrophilic resin into spaces and surfaces of braided fibers that constitute the main material of the gland packing.
CONSTITUTION: The gland packing A consists of the braided fibers 1 that constitute the major part of the packing and the filler 2 that has been impregnated into the spaces and the surfaces of the fibers 2. The filler 2 contains 1W20wt% of a hydrophilic resin 4 such as a polyethylene glycol, a polyacryl acid resin, or the like. The resin 4 contains a lubrication retaining agent 3 such as fluoroplastic fine particles, wax, or the like. Thus, the friction coefficient can be reduced due to the resin 4, the seizure with a shaft or the like can be prevented, and the lubricating property can be improved. Due to the lubrication retaining agent 3 the sealing ability can be retained, and particularly if a fluid to be sealed is aqueous, the packing is prevented from being disolved by the water that would penetrate to cause leakage.
