Abstract (en)

A process for the manufacture of packing yarn, comprising the deposition on an aromatic polyamide filament yarn, via a dispersion, of solid particles of polyfluorocarbon, and/or graphite, the yarn provided with particles being subjected to an after-blowing treatment with a fluid under pressure. Before the solid particles are deposited on the yarn, the yarn is subjected to a pre-blowing treatment with a fluid at a higher pressure, as a result of which the filaments of the yarn are interentangled and interlaced.
