Abstract
A woven fabric is described which is capable of resisting temperatures above 1000.degree. F. without significant loss of strength and which is a functional replacement for similar fabrics manufactured from asbestos. The fabric is woven with a plied yarn in which one ply is a spun yarn comprising spun aramide fibers and the other ply is a continuous glass filament yarn. The relative amounts of aramide ply and glass filament ply making up the total yarn may be varied, however a preferred yarn comprises a minor amount of aramide ply and a major amount of glass filament ply. A most preferred yarn comprises 35 percent aramide ply and 65 percent glass filament ply.
