ABSTRACT:
The present invention concerns a process for preparing essentially smooth filament yarns having several loose filament ends stick out, wherein at least a portion of the used filaments has a flex abrasion resistance of below abt. 1 500 revol. and wherein a filament bonding is imparted in known manner to the filament yarns subject to this treatment and wherein same are then submitted to a transversal stress, at which occasion the filaments having a flex abrasion resistance of below 1 500 revol. break in irregular intervals and wherein the thus obtained loose filament ends of the filament yarns may, optionally, be temporarily interlaced by known methods so as to ameliorate the filament bonding and the filament yarns so obtained. These yarns are distinguished by excellent uniform characteristics all over their length and may be worked up to fabrics having an extremely low tendency to pilling.
