ABSTRACT:
A process for producing high performance, metallic coated staple fibers and nonwoven insulating webs made up of such fibers includes providing a nonwoven substantially two-dimensional web of fibers wherein at least a portion of 50 percent of the fibers are exposed to one or the other side of the web. This web is metallized with a low emissivity metal(s) and/or alloy(s) to produce a coated web wherein at least 50 percent of the surface area of the web fibers are coated with metal and or alloy. The coated web is shredded into individual, staple fibers which are thereafter united to produce a nonwoven, lofty three-dimensional insulating web having a density of between about 0.02 to 2 pounds per cubic foot.
