Zusammenfassung:	THE SUBJECT INVENTION IS DIRECTED TO FIBERS AND POLYMER BLEND COMPOSITIONSHAVING IMPROVED BONDING PERFORMANCE. IN PARTICULAR, THE SUBJECT INVENTION PERTAINS TO A MULTICONSTITUENT FIBER COMPRISING A BLEND OF A POLYPROPYLENE POLYMER AND A HIGH MOLECULAR WEIGHT (THAT IS, LOW MELT INDEX OR MELT FLOW) ETHYLENE POLYMER. THE SUBJECT INVENTION FURTHER PERTAINS TO THE USE OF THE FIBER AND POLYMER BLEND COMPOSITION WHICH HAS IMPROVED BONDING PERFORMANCE IN VARIOUS END USE APPLICATIONS, ESPECIALLY WOVEN AND NONWOVEN FABRICS SUCH AS, FOR EXAMPLE, DISPOSABLE INCONTINENCE GARMENTS AND DIAPERS. THE FIBERS HAVE GOOD SPINNABILITY AND PROVIDE A FABRIC HAVING GOOD BOND STRENGTH AND GOOD ELONGATION.
