Publication number: 20110203226Abstract: Provided is a three-ply insulating material which has combined properties to selected gases and vapors, thermal insulation, and humidity control. The device is built as a composite of three layers. The outer layer is made from breathable non woven composite. This layer is adjacent to and bonded to the middle layer, composed of high loft fibrous material with substantial weight to volume ratio, between about 2 to about 20 kg/m3. This middle layer is adjacent to a third layer of breathable non woven composite. The composite layered structure so designed forms an insulation blanket with thermal resistance of about 0.8 m2 ° K/W and moisture vapor transmission rate (MVTR) between 50 and 10000 l/m2/hr.Type: ApplicationFiled: October 27, 2009Publication date: August 25, 2011Inventor: Yael Bonneh

Publication number: 20110184365Abstract: An absorbing structure has a sequence of layers, including at least first and second outer layers with at least a liquid storage layer disposed therebetween. The layers are disposed on top of one another and form a layered structure. At least the liquid storage layer has a cellulose material, preferably cellulose fibers, and a super absorbing polymer SAP, preferably SAP particles and/or SAP fibers. The liquid storage layer uses at least less binder material than the other liquid storing plies of the absorbing structure. The liquid storing plies are adjacent to the liquid storage layer. Preferably, the liquid storage layer does not have binder material.Type: ApplicationFiled: January 28, 2010Publication date: July 28, 2011Inventors: Henning Röttger, Stefanie Lutter, Ralf Ehmke

Publication number: 20110070420Abstract: A nonwoven is formed from one or more performance enhancing fibers together with one or more cellulosic fibers. The nonwoven could include low melting fibers for holding the nonwoven together on melting, and could include one or more optional fibers which impart a characteristic of interest to the nonwoven. The cellulosic fiber in the nonwoven is treated with fire resistant chemicals. The nonwoven has enhanced fire barrier performance, such as char elongation and char strength.Type: ApplicationFiled: October 18, 2010Publication date: March 24, 2011Applicant: TINTORIA PIANA US, INC.Inventors: Sang-Hoon Lim, Andrea Piana

Patent number: 7886378Abstract: The invention is in the field of child, human, or animal or unnatural protective covers for beds, furniture, car seats, floors, or any surface that needs to be protected from spills, or waste or bedwetting or accidental discharges of any type. The invention is washable, and has patterns that look nice and can be varied. In its preferred form, there are about five layers, with the top pleasing to the human eye and skin, which is quilted or otherwise attached to the second layer that is substantially absorbent such as a batting type of material that allows some liquid or other material to pass to the third set of liquid catching layers, which is typically a polymer having bonded thereto two cotton type fabric layers. All layers are bound together in some fashion.Type: GrantFiled: September 30, 2006Date of Patent: February 15, 2011Assignee: Incog-Neato CorporationInventor: Tammy Lynn Cheskis

Patent number: 7884038Abstract: The invention relates to a lining element, in particular an interior lining and/or covering element, for motor vehicles, having a decorative layer and a support layer structure with at least one support layer, in which the air permeability and/or density and/or the mass per unit area of the support layer structure are preset for controlling the acoustic properties, and to a method for producing a lining element, in particular an interior lining element or covering element for motor vehicles, having a decorative layer and a support layer structure of at least one support layer with controlled acoustic properties. In particular, the acoustic properties of the lining element are controlled by matching the thickness, and/or the mass per unit area, and/or the air permeability of the lining element in zones, or over the entire surface, to sound emissions which are to be absorbed.Type: GrantFiled: November 30, 2005Date of Patent: February 8, 2011Assignee: Ideal Automotive GmbHInventor: Hubert Röding
