Patent number: 9790629Abstract: A moisture vapor permeable, water impermeable composite sheet material is provided which is suitable for use as a housewrap material, and is also useful for other applications such as tarpaulins, or as covers for automobile, boats, patio furniture or the like. The composite sheet material includes a nonwoven substrate and an extrusion-coated polyolefin film layer overlying one surface of the substrate. The nonwoven substrate is comprised of polymeric fibers randomly disposed and bonded to one another to form a high tenacity nonwoven web. The nonwoven substrate has a grab tensile strength of at least 178 Newtons (40 pounds) in at least one of the machine direction (MD) or the cross-machine direction (CD). The extrusion coated polyolefin film layer is intimately bonded to the nonwoven substrate. The film layer has micropores formed therein to impart to the composite sheet material a moisture vapor transmission rate (MVTR) of at least 35 g/m2/24 hr. at 50% relative humidity and 23° C.Type: GrantFiled: November 19, 2012Date of Patent: October 17, 2017Assignee: Fiberweb, LLCInventors: Gary W. Anderson, Susannah D. Gelotte

Publication number: 20030199217Abstract: A housewrap material for controlling moisture in the walls of a building includes a moisture vapor permeable, water impermeable sheet material having opposite surfaces with a plurality of drainage channels formed in the sheet material for directing the flow of liquid and for imparting to the sheet material a three-dimensional configuration. The sheet material has a crush resistance under a load of about 2.65 psi of at least 50%. In one embodiment, the integral drainage channels are defined by a plurality of generally parallel extending peaks and valleys that allow water to be drained from the wall. The composite nonwoven material has sufficient strength and stiffness to impart significant crush resistance to the composite, so that the integral drainage channels will not be collapsed or destroyed by the subsequent application of siding, stucco, paneling or the like to the building. Preferably, the composite sheet material has a crush resistance of at least 50% when subjected to a pressure of about 2.65 psi.Type: ApplicationFiled: March 11, 2003Publication date: October 23, 2003Applicant: Reemay, Inc.Inventors: Arthur H. Cashin, Gary W. Anderson, Susannah D. Gelotte

Publication number: 20020148547Abstract: The present invention provides a nonwoven fabric of a multilayer construction including a first fibrous web layer which defines one outer surface of the nonwoven fabric and a second fibrous web layer which defines the opposite outer surface of the fabric. The first fibrous web layer comprises bicomponent or biconstituent fibers which include both a relatively higher fusion point first polymer and a lower fusion point second polymer. The second fibrous web layer comprises fibers of the relatively higher fusion point first polymer. A plurality of fusion bonds serve to bond the fibers of the first web and the fibers of the second web to form a coherent multilayer fabric. The first and second fibrous webs may be bonded directly to one another by the fusion bonds. Alternatively, one or more intermediate layers may be located between the outer first and second fibrous webs.Type: ApplicationFiled: December 27, 2001Publication date: October 17, 2002Inventors: Jean-Claude Abed, Michael Limbaugh, Susannah D.
