Controlled loft and density nonwoven webs and method for producing

摘要

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.
