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.

Abstract: The present invention provides an easy settable stretch fabric comprising three types of yarns: a rigid fiber, an elastic fiber, and a low-melt fiber, wherein the low-melt fiber comprises low-melt polymer which can be fused in the temperature between 60° C. to 200° C., being higher than the temperature used for normal textile process and household laundry, but lower than the temperature used for heat setting elastic fiber. The low-melt fiber can be selected from a group of fibers made from modified polyester, nylon, and polypropylene and the copolymer from them in the form of staple or filament.
