Abstract
Abstract A flame-retardant woven fabric is composed of a warp interwoven with a weft. The threads of the warp contain substantially exclusively staple fibers, and the threads of the weft contain substantially exclusively flame-retardant matrix fibers. The respective thicknesses and densities of the warp and weft threads can be varied so that the matrix fiber content may be varied from about 50% to about 75%, by volume, of the total.
