Abstract: Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
