Abstract

An insulated composite fabric that includes an inner fabric layer, an outer fabric layer, and an insulating-filler fabric layer enclosed between the inner fabric layer and the outer fabric layer. The insulating-filler fabric layer is a textile fabric with a raised surface on at least one side of the fabric. The insulating-filler fabric layer comprises fibers having an axial core surrounded by a multiplicity of radially extending, axially-elongated whiskers, separated by axially-extending grooves.
