Patent number: 7682995Abstract: A triple layer woven industrial fabric, particularly suitable for through-air drying applications, has a paper side (PS) layer and a machine side (MS) layer of polymeric warp and weft yarns woven to a repeat pattern wherein all the warp yarns are arranged as vertically stacked pairs, all the weft yarns comprise pairs of intrinsic weft binder yarns, and each pair of weft yarns forms an unbroken weft path in both the PS layer and the MS layer whereby when either the first or second member of the pair passes from the PS layer to the MS layer, the other member of the pair passes from the MS layer to the PS layer at an exchange point located between at least one common pair of warp yarns.Type: GrantFiled: August 4, 2004Date of Patent: March 23, 2010Assignee: AstenJohnson, Inc.Inventors: Richard Stone, Dale B. Johnson

Patent number: 7674510Abstract: A fiber fabric includes a first fiber layer formed of a plurality of first fiber bundles, a second fiber layer formed of a plurality of second fiber bundles, a retaining thread group formed of a plurality of retaining threads, and a constraint thread group formed of a plurality of constraint threads. The first fiber layer is laminated in adjacent to the second fiber layer. The first fiber bundles diagonally intersect the second fiber bundles at an angle of 45 degrees. Accordingly, it is possible to improve a production efficiency of an overlapped sheet which gives excellent moldability and a strength, and has an increased thickness by overlapping the fiber fabrics.Type: GrantFiled: June 8, 2006Date of Patent: March 9, 2010Assignee: Kabushiki Kaisha Toyota JidoshokkiInventor: Ryuta Kamiya

Publication number: 20100056006Abstract: A multilayer ceramic matrix composite structure is disclosed. The ceramic matrix composite structure may include a three-dimensional weave fabric forming a core layer. The ceramic matrix composite structure may also include a two-dimensional weave fabric attached to an outer top surface of the three-dimensional weave fabric such that the two-dimensional weave fabric forms a top layer, and a two-dimensional weave fabric attached to an outer bottom surface of the three-dimensional weave fabric generally opposite to the outer top surface such that the two-dimensional weave fabric forms a bottom layer. The structure may include increased interlaminar shear strength.Type: ApplicationFiled: September 4, 2008Publication date: March 4, 2010Inventor: Christian X. Campbell

Patent number: 7578317Abstract: In combination with a high-speed spun-bond apparatus, rather than using a circulating sieve belt for collecting the stretched filaments and forming the web, a fabric having a 4-shed double layer with support shute weave design is used. This fabric is commonly referred to as a 4B weave and 4B weave with stuffer in center. In general, the fabric has a permeability ranging from 400 to 800 cfm with a woven or pin seam where the seam permeability and caliper varies only slightly with respect to the rest of the fabric.Type: GrantFiled: October 25, 2002Date of Patent: August 25, 2009Assignee: Albany International Corp.Inventors: Mark J. Levine, David Graham, Bill Houfek, Thomas L. Israel
