ABSTRACT:
A nonwoven thermal insulating stretch fabric is provided. The fabric comprises 10 to 90 weight percent elastomeric melt blown microfiber web, the microfibers having an average diameter of less than about 25 micrometers, and 10 to 90 weight percent crimped bulking fibers. The microfibers are bonded to the bulking fibers at points of contact and the fabric has substantially uniform stretch properties such that the fabric will recover to at least 90 percent of the original dimensions within one hour after being elongated to 125 percent of the original length.
