Abstract (en)
A self-crimping continuous-filament yarn comprises latent-crimp filaments having a periodic variation in denier greater than +/- 15% about a mean value combined with filaments having a lower shrinkage than the latent-crimp filaments. Each of the latent-crimp filaments is made by converging two individual molten streams travelling at different velocities and quenching the resulting combined streams to form a combined filament. The lower-shrinkage filaments are spun simultaneously and both kinds of filaments are withdrawn at a common spinning speed in excess of 2200 meters per minute. On developing the crimp there is produced a novel yarn having high bulk and a wool-like hand comprising developed crimp filaments having a periodic variation in denier greater than +/- 15% about a mean value combined with longer filaments protruding from the yarn in loops.
