Method and apparatus for forming a fibrous media

摘要

Embodiments for methods and apparatuses for forming a nonwoven web are described herein. In one embodiment, an apparatus includes one or more sources configured to dispense a first fluid flow stream comprising a fiber and a second fluid flow stream also comprising a fiber. The apparatus also includes a mixing partition downstream from the one or more sources, where the mixing partition is positioned between the first and second flow streams from the one or more sources. The mixing partition defines one or more openings that permit fluid communication between the two flow streams. The apparatus also includes a receiving region situated downstream from the one or more sources and designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream.

1. An apparatus for making a nonwoven web, the apparatus comprising:
a) a first source configured to dispense a first fluid flow stream comprising a first fiber; b) a second source configured to dispense a second fluid flow stream comprising a second fiber, wherein the first fluid stream comprises a first fiber and the second fluid stream comprises a second fiber, wherein the second fiber has different fiber characteristics than the first fiber; b) a mixing partition downstream from the first and second sources, the mixing partition positioned between the first and second flow streams, the mixing partition defining one or more openings in the mixing partition that permit fluid communication between the two flow streams; and c) a receiving region situated downstream from the first and second sources and designed to receive at least combined first and second fluid flow streams and form a nonwoven web by collecting first and second fibers from the combined first and second fluid flow streams; wherein the receiving region is positioned below at least a portion of the mixing partition so that portions of the second fluid flow stream pass through the one or more openings of the mixing partition onto the receiving region.
