ABSTRACT:
Disclosed is a multiple-layered non-woven fabric particularly suited for use as backings for tufted carpets in view of its excellent strength and dimensional stability properties. The non-woven fabric is characterized by specifically defined strength parameters and by a graduaton of bonds throughout the thickness thereof, so that both surfaces differ from each other insofar as the degree of filament bonding is concerned.
