ABSTRACT OF THE DISCLOSURE A bonded nonwoven fabric is provided which is made from layers of continuous isotactic polypropylene filaments of specific denier and tenacity in each layer. The fabric has a machine direction layer on each of its surfaces and a cross- machine directlon layer therebetween which constitutes 40 to 60% of the total fabric welght. Each layer consists essen- tially of 65 to 90% by weight of matrix filaments and 10 to 35% by weight of isotactic polypropylene binder. The nonwovens are particularly useful as primary carpet backings for cut-pile tufted carpets having a high tufted-tongue-tear strength, low fuzz buildup on beck dyeing and high optical cover at relatively low basis weight.
