Patent number: 5983586Abstract: Fibrous insulation suitable for use in insulation cavities in buildings includes mineral fibers in an amount within the range of from about 90 to about 99 percent by weight, and organic material, in the form of organic fibers and organic particles, in an amount within the range of from about 1 to about 10 percent by weight. The mineral fibers and the organic material are integrated together so that the organic material is distributed generally uniformly among the mineral fibers. At least a majority, or about 50 percent by weight and, more preferably, a substantial amount, or about 75 percent by weight, of the organic material is in the form of organic fibers. The fibrous insulation is preferably binderless and encapsulated.Type: GrantFiled: November 24, 1997Date of Patent: November 16, 1999Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: Clarke Berdan, II, Larry J.

Patent number: 5885390Abstract: An irregularly shaped glass fiber is provided which enjoys improved resiliency, and openness in pack structures. Wool packs and other wool portions having such irregularly shaped fibers may be processed directly through needling to form a non-woven material without intervening steps such as carding or blending of fibers which accompany conventional glass fiber processing operations. In a further aspect of the invention, a non-woven material including irregularly shaped fibers in a generally continuous wool tow is produced by "unwinding" a fiberglass wool pack collected by a direct forming method. Product applications include simplified, lower cost processing, and new uses of the irregularly shaped fibers produced by rotary fiberization in filtration elements, sorbants, gaskets, packings, shingles, composite structural elements, furnishings, textiles, yarns, and blown-in insulation systems.Type: GrantFiled: September 21, 1994Date of Patent: March 23, 1999Assignee: Owens-Corning Fiberglas Technology Inc.Inventors: Roberta L. Alkire, Ralph E. Brandon, Larry J. Grant, Todd Green, George T. Henry, Kimberley A. Householder, William S. Miller

Patent number: 5876529Abstract: A method of forming an integrated pack of organic and mineral fibers includes centrifuging mineral fibers from molten mineral material using a mineral fiber spinner, directing the mineral fibers into a downwardly moving veil, generating an array of aligned organic fibers from a die and directing the organic fibers into contact with the mineral fibers to integrate the organic fibers with the mineral fibers, and collecting the integrated mineral fibers and organic fibers as a fibrous pack.Type: GrantFiled: November 24, 1997Date of Patent: March 2, 1999Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: Larry J. Grant, Michael T. Pellegrin, Jay W. Hinze, Qingyu Zeng

Patent number: 5755851Abstract: A method for collecting long glass fibers produces substantial lattice uniformity, eliminates the need for binder, and results in a generally rectangular wool pack which displays significant compressibility and recovery desired for commercial products. Generally spiral flow of fibers in the veil is captured on collecting conveyors and conveyed through direct forming apparatus with generally minimal disturbance of the spiral relationship between glass fibers. Further, a system is disclosed for producing wool insulation products of long glass fibers in accordance with the method. The principles and practices of the method and system may further be employed with short fibers to produce a wool pack of generally oriented short fibers.Type: GrantFiled: January 2, 1997Date of Patent: May 26, 1998Assignee: Owens Corning Fiberglas Technology Inc.Inventors: James W. Scott, Larry J. Grant
