Zusammenfassung:	A lofty, nonwoven material having a nonwoven web having a plurality of substantially continuous fibers oriented in a z-direction of the nonwoven web and a method for producing the lofty, nonwoven material from as-formed z-direction fibers. The method is fast, having no mechanical manipulation of the fibers to slow it down, easily adjustable and allows for in-line processing. The material can be varied from preponderantly open to preponderantly closed in its web structure. Un material no tejido y esponjado que tiene una tela no tejida que tiene una pluralidad de fibras esencialmente continuas orientadas en una direccion-z de la tela no tejida y un metodo para producir el material no tejido y esponjado de fibras en la direccion-z como son formadas. El metodo es rapido, no tiene una manipulacion mecanica de las fibras para desacelerarlas, es facilmente ajustable y permite un procesamiento en linea. El material puede ser variado de preponderantemente abierto a preponderantemente cerrado en su estructura tejida.
