Flat composite body, for use in textile applications as carpets, padding elements, floor or wall coverings

Abstract From the Canadian patent

A flat composite body (1) comprising a top layer (2) containing fibers or filaments and a support layer (3), which is at least passively needle-bondable with the two layers (2, 3) including between them an internal layer of granular particles (6) for example, sand and being needle bonded to each other through the internal layer. A composite body (1) of this configuration may be used as a self laying carpet or carpet tiles. By means of sand additions, an especially favorable sound attenutation is obtained. The high level capacity and poor thermal conductivity provide positive behavior in a fire.
