Beschreibung
Zusammenfassung:	Disclosed are fibrous structures comprised of shaped fibers wherein the thickness of the compressed fibrous structure at 1.00 psi is >/=1.3 times that of a similar compressed structure having the same area density and made from round cross section fibers of the same dpf as the shaped fibers. The invention is useful in articles such as coats, gloves, boats, shoes, etc. made using the structures disclosed herein. The surprising feature of structures according to the present invention is the thickness retention at high pressures. This retained thickness under pressure translates directly into decreased heat transfer or improved insulation.
