摘要
An apparatus for making a high loft, non-woven web exhibiting excellent recovery is disclosed. The web has a 3-dimensional structure with fibers oriented in the x, y and z directions. The apparatus includes a die having 2 to 20 rows of nozzles with each row containing a plurality of nozzles. A pair of moving surfaces is located from a distal end of each nozzle. The pair of moving surfaces form a convergent passage. A pair of heaters is used to heat each of the pair of moving surfaces. A plurality of filaments are deposited onto the pair of moving surfaces and are routed through the convergent passage to form a 3-dimensional structure having two thin outer skins.
