Method for forming a fibrous media
First Claim
1. A method of making a nonwoven web using an apparatus, comprising:
- i) dispensing, from the apparatus, a first fluid stream from a first source and a second fluid stream from a second source,ii) providing a mixing partition downstream from the first and second source, the mixing partition positioned between the first fluid stream and the second fluid stream, the mixing partition defining one or more openings in the mixing partition that permit fluid communication from at least one fluid stream to another, wherein a receiving region is positioned below at least a portion of the mixing partition so that portions of the second fluid stream pass through the openings of the mixing partition onto the first fluid stream and onto the receiving region;
iii) collecting fiber on the receiving region situated downstream from the first and second sources, the receiving region configured to receive the first and second fluid streams and form a wet layer by collecting the fiber;
iv) drying the wet layer to form the nonwoven web;
wherein the first fluid stream comprises a fiber, the second fluid stream comprises a fiber and wherein the first fluid stream has a different composition than the second fluid stream.

Abstract
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.

18. A method of making a nonwoven web using an apparatus, comprising:
-
i) dispensing a first fluid stream from a first source, wherein the first fluid stream comprises a fiber; ii) dispensing a second fluid stream from a second source, wherein the second fluid stream comprises a fiber, wherein the first fluid stream has a different composition than the second fluid stream, iii) providing a mixing partition downstream from the first and second source, the mixing partition positioned between the first fluid stream and the second fluid stream, the mixing partition defining one or more openings in the mixing partition that permit fluid communication from at least one fluid stream to another, wherein a receiving region is positioned below at least a portion of the mixing partition so that portions of the second fluid stream pass through the openings of the mixing partition onto the first fluid stream and onto the receiving region, wherein at least one of the openings extends across the entire web in the cross web direction; iv) collecting fiber on the receiving region situated downstream from the first and second sources, the receiving region configured to receive the first and second fluid streams and form a wet layer by collecting the fiber; v) drying the wet layer to form the nonwoven web.
