Abstract
Abstract HEAVIER DENIER CRIMPED YARNS OF CONTINUOUS FILAMENTS ARE DISCLOSED WHEREIN FILAMENT CRIMP AND ENTANGLEMENT PROVIDE A COMBINATION OF ELASTIC AND STABILIZED BULK WHICH IS PARTICULARLY DESIRABLE FOR TUFTED, CUT-PILE FABRICS. THE YARN BULK AND COHESIVENESS IS SUCH THAT THERE IS LITTLE BLOOMING OR EXPANDING OF THE CUT ENDS AND THE TUFTS REMAIN UPRIGHT, SO THAT GOOD TUFT DEFINITION IS MAINTAINED WHEN CARPETS ARE SUBJECTED TO HEAVY TRAFFIC. AN ECONOMICAL FLUID JET PROCESS FOR PRODUCING THE NOVEL YARN IS DISCLOSED.
