The present invention provides a nonwoven fabric laminate comprising a thermally-bonded multiconstituent fiber nonwoven web. The multiconstituent fiber is composed of a highly dispersed blend of at least two different thermoplastic polymers which are present as a dominant continuous phase and at least one noncontinuous phase dispersed therein. The noncontinuous phase exists as an elongated fibrillar polymer domain oriented generally in the direction of the fiber axis. The polymer of the noncontinuous phase has a melting temperature below that of said continuous phase, and the lower melting noncontinuous phase comprises from about 2.5 to about 20 percent by weight of the fiber. The fabric laminate also comprises at least one other web bonded to the multiconstituent fibers of the thermally bonded nonwoven web and a multiplicity of thermal bonds formed from the polymer of said multiconstituent fibers and bonding the multiconstituent fibers of said thermally bonded web to said at least one other web.
