Compatibilized blends of polypropylene, linear low density polyethylene and a low molecular weight plastomer are disclosed. The blend preferably contains at least about 50 percent by weight of crystalline polypropylene, from about 10 to about 50 percent by weight of LLDPE dispersed in a matrix of the polypropylene, and a compatibilizing amount of an ethylene/alpha-olefin plastomer having a weight average molecular weight between about 5,000 to about 50,000, a density of less than about 0.90 g/cm.sup.3, and a melt index of at least about 50 dg/min. The blend is useful in the formation of melt spun and melt blown fibers. Also disclosed are spun bonded-melt blown-spun bonded fabrics made from the blends.
