Novel bicomponent fibers have a polyamide domain and a regenerated polymer domain which is embedded entirely within, and thereby completely surrounded by, the polyamide domain. The preferred bicomponent fibers have a sheath-core structure wherein the polyamide domain constitutes the sheath and the regenerated polymer constitutes the core. Preferably, the fibers are concentric sheath-core bicomponent trilobal fibers having a virgin nylon-6 sheath and a core formed from regenerated nylon-6 obtained from recycled carpet comprised of about 90 percent nylon-6 and about 10 percent of non-polymeric contaminants. |
