Beschreibung
Zusammenfassung:	Included are multiple component elastic fibers prepared by a solution-spinning process such as dry spinning or wet spinner of spandex fibers including polyurethaneurea and polyurethane compositions. These fibers have a cross-section including at least two separate regions with definable boundaries wherein at least one region defined by the boundaries of the cross-section includes a polyurethaneurea or polyurethane composition. One region of the fiber includes a fusibility improvement additive to enhance adhesion to itself or to a substrate.
