Melt-bondable, bicomponent fibers suitable for use in nonwoven articles, said fibers having as a first component a polymer capable of forming fibers and as a second component a compatible blend of polymers capable of adhering to the surface of the first component. The second component has a melting temperature at least 30.degree. C. below the melting temperature of the first component, but at least about 130.degree. C. The blend of polymers of the second component comprises a compatible mixture of at least a partially crystalline polymer and an amorphous polymer.
