PURPOSE: To provide compound yarn suitable for production of a sliding layer of plain bearings and sliding ring seals, especially those made of fiber reinforced thermoplastics.

CONSTITUTION: A multicomponent compound yarn and processes for producing the yarn are disclosed. The compound yarn is composed of at least three components wherein a first component comprises 40-70 vol.% thermoplastic fibers, a second component comprises 10-30 vol.% polyfluorocarbon fibers and a third component comprises 10-50 vol.% fiber made of a polymer whose melting point is at least ≥20°C above the melting point of the fibers of the first component.
