20110017414 | Method for making mineral fiber paper - Disclosed is a method for making fiber paper. In this method, mineral fibers and PVA resin are blended in water, thus forming first solution. Polymer fibers and PVA resin are blended in water, thus forming second solution. The first solution is mixed with the second solution. A wet paper-making machine is used to make mineral fiber paper from the mixture. | 01-27-2011 |
20110180225 | PANELS INCLUDING RENEWABLE COMPONENTS AND METHODS FOR MANUFACTURING - A panel includes about 0.1% to about 95% by weight of a renewable component. The panel has at least one of a CAC value of at least about 25, an NRC value of at least about 0.25 and an STC of at least about 25. A method for manufacturing such panels is also provided. | 07-28-2011 |
20120312488 | Method and Apparatus for Forming a Fibrous Media - 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. | 12-13-2012 |
