ABSTRACT:
Multi-filament thermoplastic bounce crimped yarns having improved fiber-fiber coherency and intermediate non-entangled yarns and methods and apparatus for making such yarns. The process is characterized by the use of a novel bounce crimper which produces a bounce crimped yarn substantially free of filament loops and filament entanglement which is then fluid vortex interlaced to produce a very fiber-fiber coherent yarn.
