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.
