Zusammenfassung:	The present invention is directed to a high-loft nonwoven including a binder or stabilizer including a polyurethaneurea composition that provides flexibility and compression recovery to the nonwoven structure. Included is a polyurethaneurea dispersion as a stabilizer or binder for the short-length fibers which create the high-loft nonwoven structure. The invention is useful as an improved alternative for such things as polyurethane foam in applications such as bra cups.
