The disclosure is of an improved textile construction, useful as underlayment for carpeting. The construction comprises high temperature resistant staple fibers needled to a scrim of interwoven, high-temperature resistant yarns. The needled fabric has one surface treated to bond the surface fibers in place and one moisture-impervious film surface.

DETAILED DESCRIPTION The invention comprises a fire retardant, acoustic attenuating, pad which comprises; a layer of fibrous material in the form of discrete staple fibers, said layer being consolidated through entanglement of the individual fibers said entanglements being of the character produced by a needling operation, said fibers being fibers of a synthetic, high-temperature resistant, polymeric resin; and a moisture barrier attached to one surface of the fibrous material layer.
The term "high-temperature resistant" as used herein means the yarns, fibers, resins, etc.
, do not decompose and burn at temperatures lower than about 350.
degree.
