<p>Apparatus (100, 101, 102) and die cartridge assembly (18, 44, 45, 47) adaptedfor use with same for producing fibrous material (212). The apparatus (100) comprisesa removably attachable die cartridge assembly (18) that adapts to conventionalspunmelt equipment. The die cartridge assembly (18) is removably positionablebeneath an extrusion body (10) for effecting formation of fibrous material byfibrillation of polymer films. The cartridge assembly (18) includes at leastone polymer passage (19) communicating with a molten polymer source (10) fordirecting molten polymer onto at least one film forming surface (20, 28) definedby the cartridge assembly (18), and also defines at least one gas passage (222,22, 30) communicating with a gas source (16) for directing pressurized gas (220)against the molten polymer (210) in the form of a film for effecting formationof the fibrous material (212).</p> |
