<p>A process for forming a multiple component meltblown fiber comprising extruding a first distinct melt-processable polymer through a first extrusion orifice, simultaneously extruding a second distinct melt-processable polymer through a second extrusion orifice, fusing said first and second melt-processable polymers into an extruded composite filament after extrusion, and pneumatically attenuating said extruded composite filament with jets of high velocity gas so as to form said multiple component meltblown fiber.</p> |
