Patent number: 7820561Abstract: Coated, water-vapor-pervious and fungus resistant wovens, their production and also their use as sun and weather protection articles, a precleaned industrial woven fabric being treated at least once with an aqueous impregnant comprising a fungicide and a hydrophobicizer. The fabric thus impregnated and then dried is subsequently coated with an aqueous polyurethane dispersion which likewise contains a fungicide. After drying, the coated fabric is reimpregnated. The wovens are notable for fungus resistance, good water vapor perviousness and good watertightness against a high hydrohead in particular.Type: GrantFiled: May 2, 2005Date of Patent: October 26, 2010Assignee: Sattler AGInventor: Wolfgang Lube

Patent number: 7803725Abstract: A pliable reinforcement carrier membrane for use in a coated membrane composite includes a pliable non-woven fibrous mat of entangled polymeric fibers and a hydrophobic binder. The membrane is made so that a first surface of the mat has portions of a portion of the polymeric fibers of the mat protruding therefrom in extent and in sufficient amounts to give the first surface of the mat a fuzzy characteristic to facilitate adhesion of a coating material and a second surface of the fibrous mat has a generally smooth, non-fuzzy surface. A pliable waterproof composite, including the membrane, has a bottom surface formed by a filled asphalt, modified bitumen, or non-asphaltic polymeric coating that overlies and is adhered to the first surface of the mat to provide a barrier against liquid water transmission through the composite and a top surface formed by the second surface of the mat.Type: GrantFiled: January 23, 2007Date of Patent: September 28, 2010Assignee: Johns MansvilleInventors: Stephen Richard Payne, Albert George Dietz, III
