The present invention is directed to continuous filament nonwoven fabrics, and more specifically directed to continuous filament nonwoven fabrics for use as low-cost disposable airline and rescue operation blankets. Continuous filament fabrics are formed utilizing the spunbond process. The spunbond process and the manner of preparing a spunbond web is set forth in U.S. Pat. No. 3,341,394 to Kinney and U.S. Pat. No. 4,043,201 to Brock, et al., both of which are herein incorporated by reference. The filamentary blankets of the present invention may be disposed after a single use or semi-reusable, wherein the blanket has a limited number of uses before needing to be replaced. Such blankets are suitable for a variety of applications, such as insulative blankets, emergency rescue blankets, institutional blankets, airline blankets, and other applications where blankets are used only a limited number of times or in some cases only once before being discarded.
