  • Process for producing self-crimping polyamide yarns
    Patent number: 4238439
    Abstract: A melt spinning process for producing nominal 20 denier per filament polyamide yarn having a latent bulk of at least 18% is provided. The process employs polyhexamethylene adipamide modified to contain from 1 to 10 mole % of recurring units of the formula ##STR1## whereby wind-up speeds ranging from 1830 to 4570 meters per minute and higher are attainable. The resulting yarn has a usable bulk, when developed, for carpet yarn applications without further texturing of the yarn.
