Compound yarn producing the sliding layer of plain bearings made of fiber-reinforced thermoplastics
First Claim
1. A multicomponent compound yam composed of at least three components comprising a first component of from 40 to 70 percent by volume of thermoplastic fibers having a melting point above the use temperature Of the yam, a second component of from 10 to 30 percent by volume of polyfluorocarbon fibers, and a third component of from 10 to 50 percent by volume of fiber made of a polymer whose melting point is at least 20°
- C. above the melting point of the fibers of the first component, and wherein the component fibers are statistically uniformly distributed over the cross-section of the compound yarn in a multiplicity of regions in which the fibers of each component predominate in turn.

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° 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.
