An apparatus for producing a high loft, nonwoven web from a single polypropylene polymer, the nonwoven web having: (i) a fiber size distribution of from 0 μm to about 15 μm with at least about 25% of the fibers being above 4 μm, (ii) a thickness of less than about 250 millimeters, (iii) a basis weight ranging from about 50 g/m 2 to about 3,000 g/m 2, (iv) a three dimensional structure with fibers oriented in the x, y and z directions that form V, U or C-shaped structures when viewed in cross-section of the nonwoven web taken parallel to a machine direction, the apex of said V, U or C-shaped structure facing in the machine direction, and (v) a recovery value ranging from about 20% to about 99% after being compressed under a pressure of 1.7 kPa (0.25 psi) for a time period of 30 minutes, the apparatus comprising: a die connected to an extruder and having 2 to 20 rows of nozzles, each row containing a plurality of nozzles each ejecting a filament formed from the single polypropylene polymer and each of the plurality of nozzles having a distal end; a pair of movable collectors (44, 46) located between about 10 cm to about 150 cm of the distal end of each of the plurality of nozzles, a convergent passage formed by the pair of movable collectors with the convergent passage converging to a nip and having an entry that receives the filaments from the nozzles of the die and an exit that delivers the non-woven web downstream; one pair of heaters (45, 47) associated with each pair of movable collectors and heating the pair of movable collectors, the pair of heaters configured to heat the pair of movable collectors to an elevated temperature that is: less than a melting temperature of the polypropylene polymer; high enough to thermally bonding portions of the polypropylene filaments that contact the heated moving collectors at the entry of the convergent passage and form a pair of outer skins (13, 15) on the nonwoven web; and low enough to not bond the fibers in the x, y and z directions that form the V, U or C-shaped structures to each other between the pair of outer skins. a die connected to an extruder and having 2 to 20 rows of nozzles, each row containing a plurality of nozzles each ejecting a filament formed from the single polypropylene polymer and each of the plurality of nozzles having a distal end; a pair of movable collectors (44, 46) located between about 10 cm to about 150 cm of the distal end of each of the plurality of nozzles, a convergent passage formed by the pair of movable collectors with the convergent passage converging to a nip and having an entry that receives the filaments from the nozzles of the die and an exit that delivers the non-woven web downstream; one pair of heaters (45, 47) associated with each pair of movable collectors and heating the pair of movable collectors, the pair of heaters configured to heat the pair of movable collectors to an elevated temperature that is: less than a melting temperature of the polypropylene polymer; high enough to thermally bonding portions of the polypropylene filaments that contact the heated moving collectors at the entry of the convergent passage and form a pair of outer skins (13, 15) on the nonwoven web; and low enough to not bond the fibers in the x, y and z directions that form the V, U or C-shaped structures to each other between the pair of outer skins. less than a melting temperature of the polypropylene polymer; high enough to thermally bonding portions of the polypropylene filaments that contact the heated moving collectors at the entry of the convergent passage and form a pair of outer skins (13, 15) on the nonwoven web; and low enough to not bond the fibers in the x, y and z directions that form the V, U or C-shaped structures to each other between the pair of outer skins.
