Patent number: 11280033Abstract: The invention refers to a cover nonwoven for an interior lining for a vehicle, comprising a nonwoven fabric consisting of at least two nonwoven layers, a first nonwoven layer and a second nonwoven layer, wherein a first outer surface of the nonwoven fabric is formed by a surface of the first nonwoven layer and a second outer surface of the nonwoven fabric is formed by a surface of the second nonwoven layer, and wherein the first nonwoven layer and the second nonwoven layer are inseparably bonded on the entire surface. According to the invention, the first nonwoven layer is formed of a rough polypropylene spunlaced nonwoven and the second nonwoven layer is formed of a dense polypropylene spun-bonded nonwoven, wherein the first outer surface of the nonwoven fabric is suitable for the application of a pressure-sensitive adhesive, and wherein the second outer surface of the nonwoven fabric has hydrophobic properties.Type: GrantFiled: September 25, 2019Date of Patent: March 22, 2022Assignee: SANDLER AGInventors: Stefan Kreuzer, Ulrich Hornfeck

Patent number: 10857042Abstract: Disclosed is a nonwoven laminate having a texture for improved absorption and distribution of body liquids in sanitary products. The absorption and distribution effect is caused by perforations distributed in a pattern-like manner in combination with elevations present on one side of the nonwoven laminate.Type: GrantFiled: December 21, 2017Date of Patent: December 8, 2020Assignee: SANDLER AGInventors: Andreas Burger, Uwe Bernhuber, Wolfgang Höflich

Patent number: 10316445Abstract: The invention relates to an extensible non-woven, in particular, cover sheet material for a multi-layer laminate comprising hydroentangled staple fibers, where the non-woven contains 5 to 25 wt % of binder fibers made of thermoplastic material, in particular 10-15 wt % of binder fibers, and is in addition to hydroentanglement thermally bonded. Furthermore, the invention relates to an elastic multi-layer laminate for use in an elastic component for personal hygiene products composed of elastic base material covered on one or both sides by cover material, where the cover material is formed from extensible non-woven fabric.Type: GrantFiled: August 2, 2016Date of Patent: June 11, 2019Assignee: SANDLER AGInventors: Uwe Bernhuber, Alexander Obermoser

Patent number: 7772143Abstract: The invention relates to a multilayer, composite, fleece material having a core layer and at least one cover layer attached to the core layer, where the at least one cover layer is needled with the core layer such that fibers of the at least one cover layer protrude into the core layer. The multilayer, composite, fleece material is intended for use in the manufacture of interior panels of vehicles and to have improved mechanical properties, low thermal conductivity, very low tendency to produce emissions, and good acoustic properties when used for that purpose, as well as enable its inexpensive manufacture.Type: GrantFiled: September 12, 2007Date of Patent: August 10, 2010Assignee: Sandler AGInventors: Stefan Hermann, Wolfgang Höflich

Patent number: 6966939Abstract: The invention describes a multi-layer filter structure and the use of a multi-layer filter structure for the dust removal from gases, wherein a coarse dust filter layer, a fine dust filter layer, and a support layer are disposed behind one another in the direction from the inflow side to the outflow side, and which is designed such that the fiber diameter distribution within the coarse dust filter layer and fine dust filter layer has a gradient, and that the fiber diameters of the coarse dust filter layer and fine dust filter layer continually decrease from the inflow side to the outflow side. This multi-layer filter structure may be used in a filter cassette for industrial dust removal, as well as in a stationary or mobile home dust cleaning device.Type: GrantFiled: April 23, 2003Date of Patent: November 22, 2005Assignees: Branofilter GmbH, Sandler AGInventors: Jürgen Rammig, Uwe Schmierer, Ulrich Hornfeck, Roland Straub
