Abstract
Tufted carpets which are conformable and stretchable make use of a stretchable carpet backing formed from a composite fabric. The stretchable carpet backing fabric is formed of a stretchable elastic net and at least one nonwoven fibrous layer overlying the stretchable elastic net. The fibers of the fibrous layer extend through said elastic net to mechanically secure the fibrous layer to the elastic net and form a unitary coherent elastic fabric.
