ABSTRACT:
Polyamide conjugate filaments are prepared by a spinstretch process wherein two polyamides (e.g. two nylon 66 polymers) having different terminal velocity distances are melt spun at a spinning speed of at least 1829 mpm to form filaments in which the polymers are arranged in an eccentric configuration along the length of the filaments. The filaments are then stretched in-line at a stretch ratio greater than 1.0 prior to their being collected with the processing conditions and polyamides being selected to provide filaments having a high level of high-load crimp and a low level of boiling water shrinkage. The filaments are particularly useful in the construction of stretch garments and, especially, ladies' leg hose and pantyhose.
