ABSTRACT:
There are described a multicomponent compound yarn composed of at least three components, wherein a first component comprises from 40 to 70 percent by volume of thermoplastic fibers, a second component comprises from 10 to 30 percent by volume of polyfluorocarbon fibers, and a third component comprises from 10 to 50 percent by volume of fiber made of a polymer whose melting point is at least 20.degree. C. above the melting point of the fibers of the first component, and processes for producing it. The multicomponent compound yarn described is used for producing the sliding layer of plain bearings or of sliding ring seals.
