Zusammenfassung:	This invention relates to composite fabrics having two layers of nonwoven fabric comprising entangled non-bonded nylon filaments and a reinforcing layer of fiberflass scrim adhesively attached to each of the nonwoven layers. The composite fabrics are useful as backings in a carpet assembly. On décrit des tissus composites qui présentent deux couches non tissées comprenant des filaments de nylon mêlés non fusionnés, et une couche de renforcement biaise en fibres de verre, collée à chacune des couches non tissées. Ces tissus composites servent de dossiers de tapis.
